description: Build and customize EmDash CMS sites on Astro. Use when creating pages, defining collections, writing seed files, querying content, rendering Portable Text, setting up menus/taxonomies/widgets, configuring deployment, or any task involving an EmDash-powered Astro site. Assumes basic Astro knowledge but provides all EmDash-specific patterns.

# Building an EmDash Site
|
||||
|
||||
EmDash is a CMS built on Astro. It stores schema in the database (not in code), serves content via live content collections, and provides a full admin UI at `/_emdash/admin`. Sites are standard Astro projects with the `emdash` integration.
|
||||
|
||||
## Common Gotchas
|
||||
|
||||
These are the things that silently break sites. Know them before you start.
|
||||
|
||||
1. **Image fields are objects, not strings.** `post.data.featured_image` is `{ id, src, alt }`. Writing `<img src={post.data.featured_image} />` renders `[object Object]`. Use `<Image image={post.data.featured_image} />` from `"emdash/ui"`.
|
||||
|
||||
2. **`entry.id` vs `entry.data.id` are different things.** `entry.id` is the slug (use in URLs). `entry.data.id` is the database ULID (use for `getEntryTerms`, `Comments`, and other API calls that need the real ID). Mixing them up causes silent empty results.
|
||||
|
||||
3. **Taxonomy names must match the seed exactly.** If your seed defines `"name": "category"`, you must query `getTerm("category", slug)` -- not `"categories"`. Wrong name = empty results, no error.
|
||||
|
||||
4. **Always pass `cacheHint` to `Astro.cache.set()`.** Every query returns a `cacheHint`. Call `Astro.cache.set(cacheHint)` on every page that queries content, or cache invalidation won't work when editors publish changes.
|
||||
|
||||
5. **No `getStaticPaths` for CMS content.** EmDash content is dynamic. Pages must be server-rendered (`output: "server"` in `astro.config.mjs`).
|
||||
|
||||
## File Structure
|
||||
|
||||
Every EmDash site has these key files:
|
||||
|
||||
```
|
||||
my-site/
|
||||
├── astro.config.mjs # Astro config with emdash() integration
|
||||
├── src/
|
||||
│ ├── live.config.ts # EmDash loader registration (boilerplate)
|
||||
│ ├── pages/ # Astro pages (all server-rendered)
|
||||
│ ├── layouts/ # Layout components
|
||||
│ └── components/ # Reusable components
|
||||
├── seed/
|
||||
│ └── seed.json # Schema + demo content
|
||||
├── emdash-env.d.ts # Generated types (from `emdash types`)
|
||||
└── package.json
|
||||
```
|
||||
|
||||
## Workflow
|
||||
|
||||
### 1. Configure the project
|
||||
|
||||
Read **[references/configuration.md](references/configuration.md)** for `astro.config.mjs`, `live.config.ts`, deployment targets (Node vs Cloudflare), and type generation.
|
||||
|
||||
### 2. Design the schema
|
||||
|
||||
Read **[references/schema-and-seed.md](references/schema-and-seed.md)** for collection definitions, field types, taxonomies, menus, widget areas, sections, bylines, and the complete seed file format.
|
||||
|
||||
### 3. Build the pages
|
||||
|
||||
Read **[references/querying-and-rendering.md](references/querying-and-rendering.md)** for content queries, Portable Text rendering, the Image component, visual editing attributes, caching, and common page patterns (list, detail, taxonomy archive, RSS, search, 404).
|
||||
|
||||
### 4. Wire up site features
|
||||
|
||||
Read **[references/site-features.md](references/site-features.md)** for site settings, navigation menus, taxonomies, widget areas, search, SEO meta, comments, and page contributions.
|
||||
|
||||
### 5. Create the seed file
|
||||
|
||||
Write `seed/seed.json` with collections, fields, taxonomies, menus, widgets, and sample content. Validate with:
|
||||
|
||||
```bash
|
||||
npx emdash seed seed/seed.json --validate
|
||||
```
|
||||
|
||||
### 6. Run and verify
|
||||
|
||||
```bash
|
||||
npx emdash dev # Start dev server (runs migrations + seeds, and generates types)
|
||||
```
|
||||
|
||||
The admin UI is at `http://localhost:4321/_emdash/admin`.
|
||||
|
||||
## Quick API Cheat Sheet
|
||||
|
||||
```typescript
|
||||
// Content (entries have .data.byline and .data.bylines eagerly loaded)
|
||||
import { getEmDashCollection, getEmDashEntry } from "emdash";
|
||||
const { entries, nextCursor, cacheHint } = await getEmDashCollection("posts", {
|
||||
limit: 10,
|
||||
cursor,
|
||||
orderBy: { published_at: "desc" },
|
||||
});
|
||||
const { entry: post, cacheHint } = await getEmDashEntry("posts", slug);
|
||||
|
||||
// Site features
|
||||
import {
|
||||
getSiteSettings,
|
||||
getMenu,
|
||||
getTaxonomyTerms,
|
||||
getTerm,
|
||||
getEntryTerms,
|
||||
getEntriesByTerm,
|
||||
getWidgetArea,
|
||||
search,
|
||||
getSection,
|
||||
getSeoMeta,
|
||||
} from "emdash";
|
||||
|
||||
// Bylines (standalone queries -- usually not needed since entries have bylines attached)
|
||||
import { getByline, getBylineBySlug } from "emdash";
|
||||
|
||||
// UI components
|
||||
import {
|
||||
PortableText,
|
||||
Image,
|
||||
Comments,
|
||||
CommentForm,
|
||||
WidgetArea,
|
||||
EmDashHead,
|
||||
EmDashBodyStart,
|
||||
EmDashBodyEnd,
|
||||
} from "emdash/ui";
|
||||
import LiveSearch from "emdash/ui/search";
|
||||
|
||||
// Page context (for plugin contributions)
|
||||
import { createPublicPageContext } from "emdash/page";
|
||||
```
|
||||
|
||||
## Plugins
|
||||
|
||||
EmDash supports plugins for extending the CMS with hooks, storage, settings, admin UI, API routes, and custom Portable Text block types. Consider a plugin when you need to:
|
||||
|
||||
- React to content lifecycle events (e.g., send a notification on publish, sync to an external service)
|
||||
- Add custom admin pages or dashboard widgets
|
||||
- Add custom block types to the Portable Text editor (e.g., embedded maps, code playgrounds, CTAs)
|
||||
- Provide a reusable service (e.g., analytics, forms, comments via a third-party provider)
|
||||
|
||||
Plugins are registered in `astro.config.mjs`:
|
||||
|
||||
```javascript
|
||||
emdash({
|
||||
database: sqlite({ url: "file:./data.db" }),
|
||||
storage: local({ directory: "./uploads", baseUrl: "/_emdash/api/media/file" }),
|
||||
plugins: [myPlugin()],
|
||||
}),
|
||||
```
|
||||
|
||||
**To build a plugin, load the `creating-plugins` skill** (in `.agents/skills/creating-plugins/`). It covers plugin anatomy, hooks, storage, admin UI, API routes, Portable Text blocks, capabilities, and the full `definePlugin()` API.

# Configuration
|
||||
|
||||
## astro.config.mjs
|
||||
|
||||
### Node.js (local development / self-hosted)
|
||||
|
||||
```javascript
|
||||
import node from "@astrojs/node";
|
||||
import react from "@astrojs/react";
|
||||
import { defineConfig } from "astro/config";
|
||||
import emdash, { local } from "emdash/astro";
|
||||
import { sqlite } from "emdash/db";
|
||||
|
||||
export default defineConfig({
|
||||
output: "server",
|
||||
adapter: node({ mode: "standalone" }),
|
||||
image: {
|
||||
layout: "constrained",
|
||||
responsiveStyles: true,
|
||||
},
|
||||
integrations: [
|
||||
react(),
|
||||
emdash({
|
||||
database: sqlite({ url: "file:./data.db" }),
|
||||
storage: local({
|
||||
directory: "./uploads",
|
||||
baseUrl: "/_emdash/api/media/file",
|
||||
}),
|
||||
}),
|
||||
],
|
||||
devToolbar: { enabled: false },
|
||||
});
|
||||
```
|
||||
|
||||
### Cloudflare (D1 + R2)
|
||||
|
||||
```javascript
|
||||
import cloudflare from "@astrojs/cloudflare";
|
||||
import react from "@astrojs/react";
|
||||
import { d1, r2 } from "@emdash-cms/cloudflare";
|
||||
import { defineConfig } from "astro/config";
|
||||
import emdash from "emdash/astro";
|
||||
|
||||
export default defineConfig({
|
||||
output: "server",
|
||||
adapter: cloudflare(),
|
||||
image: {
|
||||
layout: "constrained",
|
||||
responsiveStyles: true,
|
||||
},
|
||||
integrations: [
|
||||
react(),
|
||||
emdash({
|
||||
database: d1({ binding: "DB", session: "auto" }),
|
||||
storage: r2({ binding: "MEDIA" }),
|
||||
}),
|
||||
],
|
||||
devToolbar: { enabled: false },
|
||||
});
|
||||
```
|
||||
|
||||
Requires a `wrangler.jsonc` with D1 and R2 bindings:
|
||||
|
||||
```jsonc
|
||||
{
|
||||
"name": "my-site",
|
||||
"compatibility_date": "2026-02-24",
|
||||
"compatibility_flags": ["nodejs_compat"],
|
||||
"assets": { "directory": "./dist" },
|
||||
"d1_databases": [
|
||||
{
|
||||
"binding": "DB",
|
||||
"database_name": "my-site",
|
||||
"database_id": "", // from `wrangler d1 create my-site`
|
||||
},
|
||||
],
|
||||
"r2_buckets": [
|
||||
{
|
||||
"binding": "MEDIA",
|
||||
"bucket_name": "my-site-media",
|
||||
},
|
||||
],
|
||||
}
|
||||
```
|
||||
|
||||
### Plugins
|
||||
|
||||
Register plugins in `astro.config.mjs`:
|
||||
|
||||
```javascript
|
||||
import { auditLogPlugin } from "@emdash-cms/plugin-audit-log";
|
||||
|
||||
emdash({
|
||||
database: sqlite({ url: "file:./data.db" }),
|
||||
storage: local({ directory: "./uploads", baseUrl: "/_emdash/api/media/file" }),
|
||||
plugins: [auditLogPlugin()],
|
||||
}),
|
||||
```
|
||||
|
||||
## live.config.ts
|
||||
|
||||
Every EmDash site needs this file at `src/live.config.ts`. It's boilerplate -- the same in every project:
|
||||
|
||||
```typescript
|
||||
import { defineLiveCollection } from "astro:content";
|
||||
import { emdashLoader } from "emdash/runtime";
|
||||
|
||||
export const collections = {
|
||||
_emdash: defineLiveCollection({ loader: emdashLoader() }),
|
||||
};
|
||||
```
|
||||
|
||||
This registers EmDash's live content collections with Astro. All content types are served through the single `_emdash` collection -- you query specific types using `getEmDashCollection("posts")` etc.
|
||||
|
||||
## emdash-env.d.ts
|
||||
|
||||
Auto-generated at the project root when the dev server starts. Provides TypeScript types for your collections. This is the file your `tsconfig.json` includes.
|
||||
|
||||
```typescript
|
||||
/// <reference types="emdash/locals" />
|
||||
|
||||
import type { PortableTextBlock } from "emdash";
|
||||
|
||||
export interface Post {
|
||||
id: string;
|
||||
slug: string | null;
|
||||
status: string;
|
||||
title: string;
|
||||
featured_image?: {
|
||||
id: string;
|
||||
src?: string;
|
||||
alt?: string;
|
||||
width?: number;
|
||||
height?: number;
|
||||
};
|
||||
content?: PortableTextBlock[];
|
||||
excerpt?: string;
|
||||
createdAt: Date;
|
||||
updatedAt: Date;
|
||||
publishedAt: Date | null;
|
||||
}
|
||||
|
||||
declare module "emdash" {
|
||||
interface EmDashCollections {
|
||||
posts: Post;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The dev server regenerates this file automatically when schema changes. You can also generate it manually:
|
||||
|
||||
## Type Generation
|
||||
|
||||
```bash
|
||||
# From local dev server (writes emdash-env.d.ts at project root)
|
||||
npx emdash types
|
||||
|
||||
# From remote instance
|
||||
npx emdash types --url https://my-site.pages.dev
|
||||
|
||||
# Custom output path
|
||||
npx emdash types --output src/types/cms.ts
|
||||
```
|
||||
|
||||
The CLI also writes `.emdash/schema.json` with the raw schema for tooling.
|
||||
|
||||
## package.json
|
||||
|
||||
Key dependencies for a Node.js site:
|
||||
|
||||
```json
|
||||
{
|
||||
"dependencies": {
|
||||
"astro": "^6.0.0",
|
||||
"emdash": "workspace:*",
|
||||
"@astrojs/node": "^9.0.0",
|
||||
"@astrojs/react": "^4.0.0",
|
||||
"react": "^18.0.0",
|
||||
"react-dom": "^18.0.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
For Cloudflare, replace `@astrojs/node` with `@astrojs/cloudflare` and add `@emdash-cms/cloudflare`.
|
||||
|
||||
## Dev Server
|
||||
|
||||
```bash
|
||||
npx emdash dev # Start dev server (runs migrations, applies seed)
|
||||
npx emdash dev --types # Start and generate types from schema
|
||||
```
|
||||
|
||||
The admin UI is at `http://localhost:4321/_emdash/admin`. On first run, you'll go through setup to create an admin account.

# Querying and Rendering Content
|
||||
|
||||
## Content Queries
|
||||
|
||||
All query functions are imported from `"emdash"`.
|
||||
|
||||
### getEmDashCollection
|
||||
|
||||
Fetch multiple entries from a collection. Returns `{ entries, error, cacheHint, nextCursor }`.
|
||||
|
||||
```typescript
|
||||
import { getEmDashCollection } from "emdash";
|
||||
|
||||
// Basic
|
||||
const { entries: posts } = await getEmDashCollection("posts");
|
||||
|
||||
// With options
|
||||
const { entries: posts, cacheHint } = await getEmDashCollection("posts", {
|
||||
status: "published",
|
||||
limit: 10,
|
||||
orderBy: { published_at: "desc" },
|
||||
where: { category: "news" },
|
||||
});
|
||||
```
|
||||
|
||||
Options:
|
||||
|
||||
- `status` -- filter by status (`"published"`, `"draft"`, etc.)
|
||||
- `limit` -- max entries
|
||||
- `cursor` -- opaque cursor for keyset pagination (pass `nextCursor` from a previous result)
|
||||
- `orderBy` -- `{ field: "asc" | "desc" }` (default: `{ created_at: "desc" }`)
|
||||
- `where` -- filter by field values or taxonomy terms. Supports arrays for OR: `{ category: ["news", "featured"] }`
|
||||
- `locale` -- filter by locale (when i18n is configured)
|
||||
|
||||
### getEmDashEntry
|
||||
|
||||
Fetch a single entry by slug. Returns `{ entry, error, isPreview, cacheHint }`.
|
||||
|
||||
```typescript
|
||||
import { getEmDashEntry } from "emdash";
|
||||
|
||||
const { entry: post, cacheHint } = await getEmDashEntry("posts", slug);
|
||||
|
||||
if (!post) {
|
||||
return Astro.redirect("/404");
|
||||
}
|
||||
```
|
||||
|
||||
### Entry Shape
|
||||
|
||||
```typescript
|
||||
interface ContentEntry<T> {
|
||||
id: string; // The slug (used in URLs)
|
||||
data: T; // All fields, including system fields
|
||||
edit: EditProxy; // Visual editing attributes (spread onto elements)
|
||||
}
|
||||
|
||||
// data includes system fields plus your custom fields:
|
||||
interface PostData {
|
||||
id: string; // Database ULID (use for taxonomy lookups, etc.)
|
||||
slug: string;
|
||||
status: string;
|
||||
title: string;
|
||||
featured_image?: {
|
||||
id: string;
|
||||
src?: string;
|
||||
alt?: string;
|
||||
width?: number;
|
||||
height?: number;
|
||||
};
|
||||
content?: PortableTextBlock[];
|
||||
createdAt: Date;
|
||||
updatedAt: Date;
|
||||
publishedAt: Date | null;
|
||||
// Bylines (eagerly loaded)
|
||||
byline: BylineSummary | null; // Primary author
|
||||
bylines: ContentBylineCredit[]; // All credits (with roleLabel, source)
|
||||
// ... your custom fields
|
||||
}
|
||||
```
|
||||
|
||||
**Important:** `entry.id` is the slug (for URLs), `entry.data.id` is the database ULID (for API calls like `getEntryTerms`).
|
||||
|
||||
### Caching
|
||||
|
||||
Query results include a `cacheHint` for Astro's Route Caching:
|
||||
|
||||
```astro
|
||||
---
|
||||
const { entries: posts, cacheHint } = await getEmDashCollection("posts");
|
||||
Astro.cache.set(cacheHint);
|
||||
---
|
||||
```
|
||||
|
||||
Always call `Astro.cache.set(cacheHint)` -- it enables automatic cache invalidation when content changes.
|
||||
|
||||
## Rendering Portable Text
|
||||
|
||||
### PortableText component
|
||||
|
||||
```astro
|
||||
---
|
||||
import { PortableText } from "emdash/ui";
|
||||
---
|
||||
<PortableText value={post.data.content} />
|
||||
```
|
||||
|
||||
Renders standard blocks (paragraphs, headings, lists, blockquotes, code blocks, images) and inline marks (bold, italic, code, strikethrough, links).
|
||||
|
||||
### Custom block types
|
||||
|
||||
For custom PT blocks (e.g., marketing components), pass a `components` prop:
|
||||
|
||||
```astro
|
||||
---
|
||||
import { PortableText } from "emdash/ui";
|
||||
import Hero from "./blocks/Hero.astro";
|
||||
import Features from "./blocks/Features.astro";
|
||||
|
||||
const customTypes = {
|
||||
"marketing.hero": Hero,
|
||||
"marketing.features": Features,
|
||||
};
|
||||
---
|
||||
<PortableText value={page.data.content} components={{ type: customTypes }} />
|
||||
```
|
||||
|
||||
Each custom component receives the block data as props.
|
||||
|
||||
## Image Component
|
||||
|
||||
**Always use the EmDash Image component for CMS images.** Image fields are objects, not strings.
|
||||
|
||||
```astro
|
||||
---
|
||||
import { Image } from "emdash/ui";
|
||||
---
|
||||
|
||||
{/* Correct -- passes the image object */}
|
||||
<Image image={post.data.featured_image} />
|
||||
|
||||
{/* Also works with explicit props */}
|
||||
{post.data.featured_image?.src && (
|
||||
<img src={post.data.featured_image.src} alt={post.data.featured_image.alt || ""} />
|
||||
)}
|
||||
```
|
||||
|
||||
**Common mistake:**
|
||||
|
||||
```astro
|
||||
{/* WRONG -- image is an object, not a string */}
|
||||
<img src={post.data.featured_image} />
|
||||
```
|
||||
|
||||
## Visual Editing Attributes
|
||||
|
||||
Entries include `edit` attributes for inline editing. Spread them onto the element that displays the field:
|
||||
|
||||
```astro
|
||||
<h1 {...post.edit.title}>{post.data.title}</h1>
|
||||
<p {...post.edit.excerpt}>{post.data.excerpt}</p>
|
||||
<div {...post.edit.featured_image}>
|
||||
<Image image={post.data.featured_image} />
|
||||
</div>
|
||||
```
|
||||

## Common Page Patterns
|
||||
|
||||
### List page (e.g., `/posts/index.astro`)
|
||||
|
||||
```astro
|
||||
---
|
||||
import { getEmDashCollection, getEntryTerms } from "emdash";
|
||||
import { Image } from "emdash/ui";
|
||||
import Base from "../../layouts/Base.astro";
|
||||
|
||||
const { entries: posts, cacheHint } = await getEmDashCollection("posts", {
|
||||
orderBy: { published_at: "desc" },
|
||||
});
|
||||
Astro.cache.set(cacheHint);
|
||||
|
||||
const sortedPosts = posts.toSorted((a, b) => {
|
||||
const dateA = a.data.publishedAt?.getTime() ?? 0;
|
||||
const dateB = b.data.publishedAt?.getTime() ?? 0;
|
||||
return dateB - dateA;
|
||||
});
|
||||
---
|
||||
<Base title="Posts">
|
||||
{sortedPosts.map(post => (
|
||||
<article>
|
||||
{post.data.featured_image && <Image image={post.data.featured_image} />}
|
||||
<a href={`/posts/${post.id}`}>{post.data.title}</a>
|
||||
{post.data.excerpt && <p>{post.data.excerpt}</p>}
|
||||
</article>
|
||||
))}
|
||||
</Base>
|
||||
```
|
||||
|
||||
### Detail page (e.g., `/posts/[slug].astro`)
|
||||
|
||||
```astro
|
||||
---
|
||||
import { getEmDashEntry, getEntryTerms, getSeoMeta } from "emdash";
|
||||
import { Image, PortableText } from "emdash/ui";
|
||||
import Base from "../../layouts/Base.astro";
|
||||
|
||||
const { slug } = Astro.params;
|
||||
if (!slug) return Astro.redirect("/404");
|
||||
|
||||
const { entry: post, cacheHint } = await getEmDashEntry("posts", slug);
|
||||
if (!post) return Astro.redirect("/404");
|
||||
|
||||
Astro.cache.set(cacheHint);
|
||||
|
||||
const seo = getSeoMeta(post, {
|
||||
siteTitle: "My Blog",
|
||||
siteUrl: Astro.url.origin,
|
||||
path: `/posts/${slug}`,
|
||||
});
|
||||
|
||||
const tags = await getEntryTerms("posts", post.data.id, "tag");
|
||||
---
|
||||
<Base title={seo.title} description={seo.description}>
|
||||
<article>
|
||||
{post.data.featured_image && (
|
||||
<div {...post.edit.featured_image}>
|
||||
<Image image={post.data.featured_image} />
|
||||
</div>
|
||||
)}
|
||||
<h1 {...post.edit.title}>{post.data.title}</h1>
|
||||
<PortableText value={post.data.content} />
|
||||
{tags.length > 0 && (
|
||||
<div>
|
||||
{tags.map(t => <a href={`/tag/${t.slug}`}>{t.label}</a>)}
|
||||
</div>
|
||||
)}
|
||||
</article>
|
||||
</Base>
|
||||
```
|
||||
|
||||
### Taxonomy archive (e.g., `/category/[slug].astro`)
|
||||
|
||||
```astro
|
||||
---
|
||||
import { getTerm, getEmDashCollection } from "emdash";
|
||||
import Base from "../../layouts/Base.astro";
|
||||
|
||||
const { slug } = Astro.params;
|
||||
const term = slug ? await getTerm("category", slug) : null;
|
||||
if (!term) return Astro.redirect("/404");
|
||||
|
||||
const { entries: posts } = await getEmDashCollection("posts", {
|
||||
where: { category: term.slug },
|
||||
orderBy: { published_at: "desc" },
|
||||
});
|
||||
---
|
||||
<Base title={`${term.label} posts`}>
|
||||
<h1>{term.label}</h1>
|
||||
{posts.map(post => (
|
||||
<a href={`/posts/${post.id}`}>{post.data.title}</a>
|
||||
))}
|
||||
</Base>
|
||||
```
|
||||
|
||||
### RSS feed (e.g., `/rss.xml.ts`)
|
||||
|
||||
```typescript
|
||||
import type { APIRoute } from "astro";
|
||||
import { getEmDashCollection } from "emdash";
|
||||
|
||||
const siteTitle = "My Site";
|
||||
|
||||
export const GET: APIRoute = async ({ url }) => {
|
||||
const siteUrl = url.origin;
|
||||
const { entries: posts } = await getEmDashCollection("posts", {
|
||||
orderBy: { published_at: "desc" },
|
||||
limit: 20,
|
||||
});
|
||||
|
||||
const items = posts
|
||||
.filter((p) => p.data.publishedAt)
|
||||
.map((post) => {
|
||||
const postUrl = `${siteUrl}/posts/${post.id}`;
|
||||
return ` <item>
|
||||
<title>${escapeXml(post.data.title)}</title>
|
||||
<link>${postUrl}</link>
|
||||
<guid isPermaLink="true">${postUrl}</guid>
|
||||
<pubDate>${post.data.publishedAt!.toUTCString()}</pubDate>
|
||||
<description>${escapeXml(post.data.excerpt || "")}</description>
|
||||
</item>`;
|
||||
})
|
||||
.join("\n");
|
||||
|
||||
return new Response(
|
||||
`<?xml version="1.0" encoding="UTF-8"?>
|
||||
<rss version="2.0" xmlns:atom="http://www.w3.org/2005/Atom">

||||

|
||||
<title>${escapeXml(siteTitle)}</title>

|
||||

|
||||

|
||||

|
||||

|
||||
{
|
||||
headers: {
|
||||
"Content-Type": "application/rss+xml; charset=utf-8",
|
||||
"Cache-Control": "public, max-age=3600",
|
||||
},
|
||||
},
|
||||
);
|
||||
};
|
||||
|
||||
function escapeXml(s: string): string {
|
||||
return s
|
||||
.replace(/&/g, "&")
|
||||
.replace(/</g, "<")
|
||||
.replace(/>/g, ">")
|
||||
.replace(/"/g, """)
|
||||
.replace(/'/g, "'");
|
||||
}
|
||||
```
|
||||
|
||||
### 404 page (`/404.astro`)
|
||||
|
||||
```astro
|
||||
---
|
||||
import Base from "../layouts/Base.astro";
|
||||
---
|
||||
<Base title="Not Found">
|
||||
<h1>Page not found</h1>
|
||||
<p>The page you're looking for doesn't exist.</p>
|
||||
<a href="/">Go home</a>
|
||||
</Base>
|
||||
```
|
||||
|
||||
### Empty state
|
||||
|
||||
When a collection has no content, show a helpful empty state:
|
||||
|
||||
```astro
|
||||
{posts.length === 0 ? (
|
||||
<section>
|
||||
<h2>No posts yet</h2>
|
||||
<p>Create your first post in the admin panel.</p>
|
||||
<a href="/_emdash/admin/content/posts/new">Create a post</a>
|
||||
</section>
|
||||
) : (
|
||||
/* ... render posts ... */
|
||||
)}
|
||||
```
|
||||
|
||||
## Pagination
|
||||
|
||||
`getEmDashCollection` supports cursor-based keyset pagination. Pass `cursor` from a previous result's `nextCursor` to get the next page:
|
||||
|
||||
```astro
|
||||
---
|
||||
const cursor = Astro.url.searchParams.get("cursor") ?? undefined;
|
||||
const { entries, nextCursor, cacheHint } = await getEmDashCollection("posts", {
|
||||
limit: 10,
|
||||
cursor,
|
||||
orderBy: { published_at: "desc" },
|
||||
});
|
||||
Astro.cache.set(cacheHint);
|
||||
---
|
||||
{entries.map(post => (
|
||||
<a href={`/posts/${post.id}`}>{post.data.title}</a>
|
||||
))}
|
||||
{nextCursor && <a href={`?cursor=${nextCursor}`}>Next page</a>}
|
||||
```
|
||||
|
||||
`nextCursor` is `undefined` when there are no more results.
|
||||
|
||||
## Date Formatting
|
||||
|
||||
Dates come as `Date` objects. Use `toLocaleDateString` or `Intl.DateTimeFormat`:
|
||||
|
||||
```typescript
|
||||
const formatted = post.data.publishedAt?.toLocaleDateString("en-US", {
|
||||
year: "numeric",
|
||||
month: "long",
|
||||
day: "numeric",
|
||||
});
|
||||
```

# Schema and Seed Files
|
||||
|
||||
The seed file (`seed/seed.json`) defines the site's entire schema and optional demo content. It's applied on first run or via `npx emdash seed seed/seed.json`.
|
||||
|
||||
## Seed File Structure
|
||||
|
||||
```json
|
||||
{
|
||||
"$schema": "https://emdashcms.com/seed.schema.json",
|
||||
"version": "1",
|
||||
"meta": {
|
||||
"name": "My Site",
|
||||
"description": "A description of this site",
|
||||
"author": "Author Name"
|
||||
},
|
||||
"settings": { ... },
|
||||
"collections": [ ... ],
|
||||
"taxonomies": [ ... ],
|
||||
"menus": [ ... ],
|
||||
"widgetAreas": [ ... ],
|
||||
"sections": [ ... ],
|
||||
"bylines": [ ... ],
|
||||
"content": { ... }
|
||||
}
|
||||
```
|
||||
|
||||
## Collections
|
||||
|
||||
Collections define content types. Each collection becomes a database table (`ec_{slug}`).
|
||||
|
||||
```json
|
||||
{
|
||||
"slug": "posts",
|
||||
"label": "Posts",
|
||||
"labelSingular": "Post",
|
||||
"supports": ["drafts", "revisions", "search", "seo"],
|
||||
"commentsEnabled": true,
|
||||
"fields": [ ... ]
|
||||
}
|
||||
```
|
||||
|
||||
### Collection Supports
|
||||
|
||||
| Support | Description |
|
||||
| ----------- | ------------------------- |
|
||||
| `drafts` | Draft/published workflow |
|
||||
| `revisions` | Revision history |
|
||||
| `search` | Full-text search indexing |
|
||||
| `seo` | SEO meta fields in admin |
|
||||
|
||||
### Slug Rules
|
||||
|
||||
- Lowercase alphanumeric + underscores: `/^[a-z][a-z0-9_]*$/`
|
||||
- Max 63 characters
|
||||
- Cannot conflict with reserved slugs
|
||||
|
||||
## Field Types
|
||||
|
||||
| Type | Column type | Runtime shape | Notes |
|
||||
| -------------- | ----------- | ------------------------------------- | ---------------------------- |
|
||||
| `string` | TEXT | `string` | Single line text |
|
||||
| `text` | TEXT | `string` | Multi-line text (textarea) |
|
||||
| `number` | REAL | `number` | Floating point |
|
||||
| `integer` | INTEGER | `number` | Whole numbers |
|
||||
| `boolean` | INTEGER | `boolean` | Stored as 0/1 |
|
||||
| `datetime` | TEXT | `Date` | ISO 8601 string in DB |
|
||||
| `image` | TEXT | `{ id, src?, alt?, width?, height? }` | **Object, not a string** |
|
||||
| `reference` | TEXT | `string` (ID) | Reference to another entry |
|
||||
| `portableText` | JSON | `PortableTextBlock[]` | Rich text as structured JSON |
|
||||
| `json` | JSON | `any` | Arbitrary JSON data |
|
||||
|
||||
### Field Definition
|
||||
|
||||
```json
|
||||
{
|
||||
"slug": "title",
|
||||
"label": "Title",
|
||||
"type": "string",
|
||||
"required": true,
|
||||
"searchable": true
|
||||
}
|
||||
```
|
||||
|
||||
Fields can have:
|
||||
|
||||
- `slug` (required) -- field identifier
|
||||
- `label` (required) -- display label in admin
|
||||
- `type` (required) -- one of the types above
|
||||
- `required` -- validation
|
||||
- `searchable` -- include in full-text search index
|
||||
|
||||
### Common Field Patterns
|
||||
|
||||
**Blog post:**
|
||||
|
||||
```json
|
||||
"fields": [
|
||||
{ "slug": "title", "label": "Title", "type": "string", "required": true, "searchable": true },
|
||||
{ "slug": "featured_image", "label": "Featured Image", "type": "image" },
|
||||
{ "slug": "content", "label": "Content", "type": "portableText", "searchable": true },
|
||||
{ "slug": "excerpt", "label": "Excerpt", "type": "text" }
|
||||
]
|
||||
```
|
||||
|
||||
**Portfolio project:**
|
||||
|
||||
```json
|
||||
"fields": [
|
||||
{ "slug": "title", "label": "Title", "type": "string", "required": true, "searchable": true },
|
||||
{ "slug": "featured_image", "label": "Featured Image", "type": "image", "required": true },
|
||||
{ "slug": "client", "label": "Client", "type": "string" },
|
||||
{ "slug": "year", "label": "Year", "type": "string" },
|
||||
{ "slug": "summary", "label": "Summary", "type": "text", "searchable": true },
|
||||
{ "slug": "content", "label": "Content", "type": "portableText", "searchable": true },
|
||||
{ "slug": "gallery", "label": "Gallery", "type": "json" },
|
||||
{ "slug": "url", "label": "Project URL", "type": "string" }
|
||||
]
|
||||
```
|
||||
|
||||
**Page (minimal):**
|
||||
|
||||
```json
|
||||
"fields": [
|
||||
{ "slug": "title", "label": "Title", "type": "string", "required": true, "searchable": true },
|
||||
{ "slug": "content", "label": "Content", "type": "portableText", "searchable": true }
|
||||
]
|
||||
```
|
||||
|
||||
## Taxonomies
|
||||
|
||||
Taxonomies are tag/category systems attached to collections.
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "category",
|
||||
"label": "Categories",
|
||||
"labelSingular": "Category",
|
||||
"hierarchical": true,
|
||||
"collections": ["posts"],
|
||||
"terms": [
|
||||
{ "slug": "development", "label": "Development" },
|
||||
{ "slug": "design", "label": "Design" }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
- `hierarchical: true` -- tree structure (like WordPress categories)
|
||||
- `hierarchical: false` -- flat list (like WordPress tags)
|
||||
- `collections` -- which collections this taxonomy applies to
|
||||
- `terms` -- pre-defined terms to create
|
||||
|
||||
## Menus
|
||||
|
||||
Navigation menus, managed from the admin UI.
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "primary",
|
||||
"label": "Primary Navigation",
|
||||
"items": [
|
||||
{ "type": "custom", "label": "Home", "url": "/" },
|
||||
{ "type": "custom", "label": "About", "url": "/pages/about" },
|
||||
{ "type": "custom", "label": "Posts", "url": "/posts" }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
Menu item types:
|
||||
|
||||
- `custom` -- arbitrary URL
|
||||
- Content references are resolved at render time
|
||||
|
||||
## Widget Areas
|
||||
|
||||
Named regions where editors can add configurable widgets.
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "sidebar",
|
||||
"label": "Sidebar",
|
||||
"description": "Widget area displayed on single post pages",
|
||||
"widgets": [
|
||||
{
|
||||
"type": "component",
|
||||
"componentId": "core:search",
|
||||
"title": "Search"
|
||||
},
|
||||
{
|
||||
"type": "component",
|
||||
"componentId": "core:categories",
|
||||
"title": "Categories"
|
||||
},
|
||||
{
|
||||
"type": "component",
|
||||
"componentId": "core:tags",
|
||||
"title": "Tags"
|
||||
},
|
||||
{
|
||||
"type": "component",
|
||||
"componentId": "core:recent-posts",
|
||||
"title": "Recent Posts",
|
||||
"settings": { "count": 5, "showDate": true }
|
||||
},
|
||||
{
|
||||
"type": "component",
|
||||
"componentId": "core:archives",
|
||||
"title": "Archives",
|
||||
"settings": { "type": "monthly", "limit": 6 }
|
||||
},
|
||||
{
|
||||
"type": "content",
|
||||
"title": "About",
|
||||
"content": [
|
||||
{
|
||||
"_type": "block",
|
||||
"style": "normal",
|
||||
"children": [{ "_type": "span", "text": "Some rich text content." }]
|
||||
}
|
||||
]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Widget types
|
||||
|
||||
| Type | Description | Key fields |
|
||||
| ----------- | ------------------------- | ------------------------- |
|
||||
| `content` | Rich text (Portable Text) | `content` |
|
||||
| `menu` | Navigation menu | `menuName` |
|
||||
| `component` | Core or custom component | `componentId`, `settings` |
|
||||
|
||||
### Core widget components
|
||||
|
||||
- `core:search` -- search form
|
||||
- `core:categories` -- category list with counts
|
||||
- `core:tags` -- tag cloud
|
||||
- `core:recent-posts` -- latest posts list
|
||||
- `core:archives` -- monthly archive links
|
||||
|
||||
## Sections (Reusable Blocks)
|
||||
|
||||
Reusable content blocks that editors can insert via `/section` slash command in the editor.
|
||||
|
||||
```json
|
||||
{
|
||||
"slug": "newsletter-signup",
|
||||
"title": "Newsletter Signup",
|
||||
"description": "A call-to-action block for newsletter subscriptions",
|
||||
"keywords": ["newsletter", "subscribe", "email", "cta"],

"_type": "block",
|
||||
"style": "h3",
|
||||
"children": [{ "_type": "span", "text": "Stay in the loop" }]
|
||||
},

"style": "normal",
|
||||
"children": [{ "_type": "span", "text": "Get notified when new posts are published." }]
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
## Bylines
|
||||
|
||||
Named author profiles, independent of user accounts.
|
||||
|
||||
```json
|
||||

}
|
||||
}
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Media references in seed content
|
||||
|
||||
Use `$media` for image fields -- EmDash downloads and stores the image:
|
||||
|
||||
```json
|
||||
"featured_image": {
|
||||
"$media": {
|
||||
"url": "https://images.unsplash.com/photo-xxx?w=1200&h=800&fit=crop",
|
||||
"alt": "Description",
|
||||
"filename": "my-image.jpg"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
For external images without downloading:
|
||||
|
||||
```json
|
||||
"featured_image": "https://images.unsplash.com/photo-xxx?w=1200"
|
||||
```
|
||||
|
||||
### Reference fields in seed content
|
||||
|
||||
Use `$ref:id` format to reference other entries:
|
||||
|
||||
```json
|
||||
"author": "$ref:byline-editorial"
|
||||
```
|
||||
|
||||
### Portable Text in seed content
|
||||
|
||||
Content fields of type `portableText` are arrays of blocks:
|
||||
|
||||
```json
|
||||
[
|
||||
{
|
||||
"_type": "block",
|
||||
"style": "normal",
|
||||
"children": [{ "_type": "span", "text": "A paragraph." }]
|
||||
},
|
||||
{
|
||||
"_type": "block",
|
||||
"style": "h2",
|
||||
"children": [{ "_type": "span", "text": "A heading" }]
|
||||
},
|
||||
{
|
||||
"_type": "block",
|
||||
"style": "blockquote",
|
||||
"children": [{ "_type": "span", "text": "A quote." }]
|
||||
}
|
||||
]
|
||||
```
|
||||
|
||||
Inline marks (bold, italic, links):
|
||||
|
||||
```json
|
||||
{
|
||||
"_type": "block",
|
||||
"style": "normal",
|
||||
"children": [
|
||||
{ "_type": "span", "text": "This is " },
|
||||
{ "_type": "span", "text": "bold", "marks": ["strong"] },
|
||||
{ "_type": "span", "text": " and " },
|
||||
{ "_type": "span", "text": "italic", "marks": ["em"] }
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
Block styles: `normal`, `h1`-`h6`, `blockquote`.
|
||||
|
||||
### Draft content
|
||||
|
||||
Set `"status": "draft"` to create unpublished content:
|
||||
|
||||
```json
|
||||
{
|
||||
"id": "post-draft",
|
||||
"slug": "work-in-progress",
|
||||
"status": "draft",
|
||||
"data": { ... }
|
||||
}
|
||||
```
|
||||
|
||||
## Validation
|
||||
|
||||
```bash
|
||||
npx emdash seed seed/seed.json --validate
|
||||
```
|
||||
|
||||
Catches:
|
||||
|
||||
- Image fields with raw URLs (should use `$media`)
|
||||
- Reference fields with raw IDs (should use `$ref:id`)
|
||||
- PortableText not an array or missing `_type`
|
||||
- Type mismatches (string vs number, etc.)
|
||||
|
||||
## Applying Seeds
|
||||
|
||||
```bash
|
||||
npx emdash seed seed/seed.json # Apply with content
|
||||
npx emdash seed seed/seed.json --no-content # Schema only (no sample content)
|
||||
```
|
||||
|
||||
## Exporting Seeds
|
||||
|
||||
```bash
|
||||
npx emdash export-seed # Schema only
|
||||
npx emdash export-seed --with-content # Schema + all content
|
||||
npx emdash export-seed --with-content=posts,pages # Specific collections

# Site Features
|
||||
|
||||
## Site Settings
|
||||
|
||||
```typescript
|
||||
import { getSiteSettings, getSiteSetting } from "emdash";
|
||||
|
||||
// All settings
|
||||
const settings = await getSiteSettings();
|
||||
settings.title; // "My Site"
|
||||
settings.tagline; // "A description"
|
||||
settings.logo?.url; // Resolved media URL
|
||||
settings.favicon?.url;
|
||||
|
||||
// Single setting
|
||||
const title = await getSiteSetting("title");
|
||||
```
|
||||
|
||||
Available keys: `title`, `tagline`, `logo`, `favicon`, `social`, `timezone`, `dateFormat`.
|
||||
|
||||
Use these instead of hard-coding site name, logo, etc.
|
||||
|
||||
## Navigation Menus
|
||||
|
||||
```typescript
|
||||
import { getMenu, getMenus } from "emdash";
|
||||
|
||||
// Fetch a named menu
|
||||
const menu = await getMenu("primary");
|
||||
|
||||
// List all menus
|
||||
const menus = await getMenus();
|
||||
```
|
||||
|
||||
### Rendering a menu
|
||||
|
||||
```astro
|
||||
---
|
||||
import { getMenu } from "emdash";
|
||||
const primaryMenu = await getMenu("primary");
|
||||
---
|
||||
<nav>
|
||||
{primaryMenu?.items.map(item => (
|
||||
<a href={item.url} target={item.target}>{item.label}</a>
|
||||
))}
|
||||
</nav>
|
||||
```
|
||||
|
||||
### Nested menus (dropdowns)
|
||||
|
||||
```astro
|
||||
{primaryMenu?.items.map(item => (
|
||||
<li>
|
||||
<a href={item.url}>{item.label}</a>
|
||||
{item.children.length > 0 && (
|
||||
<ul class="submenu">
|
||||
{item.children.map(child => (
|
||||
<li><a href={child.url}>{child.label}</a></li>
|
||||
))}
|
||||
</ul>
|
||||
)}
|
||||
</li>
|
||||
))}
|
||||
```
|
||||
|
||||
### MenuItem shape
|
||||
|
||||
```typescript
|
||||
interface MenuItem {
|
||||
id: string;
|
||||
label: string;
|
||||
url: string; // Resolved URL
|
||||
target?: string; // "_blank" etc.
|
||||
children: MenuItem[];
|
||||
}
|
||||
```
|
||||
|
||||
## Taxonomies
|
||||
|
||||
```typescript
|
||||
import { getTaxonomyTerms, getTerm, getEntryTerms, getEntriesByTerm } from "emdash";
|
||||
|
||||
// All terms in a taxonomy (name must match your seed's "name" field exactly)
|
||||
const categories = await getTaxonomyTerms("category");
|
||||
const tags = await getTaxonomyTerms("tag");
|
||||
|
||||
// Single term by slug
|
||||
const term = await getTerm("category", "news");
|
||||
// { id, name, slug, label, children, count }
|
||||
|
||||
// Terms for a specific entry (use data.id, not entry.id!)
|
||||
const postCategories = await getEntryTerms("posts", post.data.id, "category");
|
||||
const postTags = await getEntryTerms("posts", post.data.id, "tag");
|
||||
|
||||
// Entries with a specific term
|
||||
const newsPosts = await getEntriesByTerm("posts", "category", "news");
|
||||
```
|
||||
|
||||
**Important:** The taxonomy name argument must match exactly what your seed defines in `"name"`. The blog seed uses `"category"` and `"tag"` (singular). Using `"categories"` returns empty results with no error.
|
||||
|
||||
**Important:** `getEntryTerms` takes the database ULID (`post.data.id`), not the slug (`post.id`).
|
||||
|
||||
### Displaying post terms
|
||||
|
||||
```astro
|
||||
---
|
||||
const tags = await getEntryTerms("posts", post.data.id, "tag");
|
||||
---
|
||||
{tags.map(t => (
|
||||
<a href={`/tag/${t.slug}`}>{t.label}</a>
|
||||
))}
|
||||
```
|
||||
|
||||
### Filtering by taxonomy
|
||||
|
||||
```astro
|
||||
---
|
||||
const { entries: posts } = await getEmDashCollection("posts", {
|
||||
where: { category: term.slug },
|
||||
orderBy: { published_at: "desc" },
|
||||
});
|
||||
---
|
||||
```
|
||||
|
||||
## Widget Areas
|
||||
|
||||
Render a named widget area:
|
||||
|
||||
```astro
|
||||
---
|
||||
import { WidgetArea } from "emdash/ui";
|
||||
---
|
||||
<aside>
|
||||
<WidgetArea name="sidebar" />
|
||||
</aside>
|
||||
```
|
||||
|
||||
The `WidgetArea` component automatically renders all widgets in the area (search, categories, tags, recent posts, rich text, etc.) with appropriate HTML and CSS classes.
|
||||
|
||||
### Manual widget rendering
|
||||
|
||||
For more control, use the `getWidgetArea` function:
|
||||
|
||||
```astro
|
||||
---
|
||||
import { getWidgetArea } from "emdash";
|
||||
import { PortableText } from "emdash/ui";
|
||||
|
||||
const sidebar = await getWidgetArea("sidebar");
|
||||
---
|
||||
{sidebar?.widgets.map(widget => (
|
||||
<div class="widget">
|
||||
{widget.title && <h3>{widget.title}</h3>}
|
||||
{widget.type === "content" && widget.content && (
|
||||
<PortableText value={widget.content} />
|
||||
)}
|
||||
</div>
|
||||
))}
|
||||
```
|
||||
|
||||
## Search
|
||||
|
||||
### LiveSearch component (instant search)
|
||||
|
||||
```astro
|
||||
---
|
||||
import LiveSearch from "emdash/ui/search";
|
||||
---
|
||||
<LiveSearch
|
||||
placeholder="Search..."
|
||||
collections={["posts", "pages"]}
|
||||
/>
|
||||
```
|
||||
|
||||
Customizable CSS classes:
|
||||
|
||||
```astro
|
||||
<LiveSearch
|
||||
placeholder="Search..."
|
||||
class="site-search"
|
||||
inputClass="site-search-input"
|
||||
resultsClass="site-search-results"
|
||||
resultClass="site-search-result"
|
||||
collections={["posts", "pages"]}
|
||||
expandOnFocus={{ collapsed: "180px", expanded: "280px" }}
|
||||
/>
|
||||
```
|
||||
|
||||
Theme via CSS variables:
|
||||
|
||||
```css
|
||||
:root {
|
||||
--emdash-search-bg: var(--color-bg);
|
||||
--emdash-search-text: var(--color-text);
|
||||
--emdash-search-muted: var(--color-muted);
|
||||
--emdash-search-border: var(--color-border);
|
||||
--emdash-search-hover: var(--color-surface);
|
||||
--emdash-search-highlight: var(--color-text);
|
||||
}
|
||||
```
|
||||
|
||||
### Programmatic search
|
||||
|
||||
```typescript
|
||||
import { search } from "emdash";
|
||||
|
||||
const results = await search("hello world", {
|
||||
collections: ["posts", "pages"],
|
||||
status: "published",
|
||||
limit: 20,
|
||||
});
|
||||
// { results: SearchResult[], total, nextCursor? }
|
||||
```
|
||||
|
||||
Each result has: `collection`, `id`, `title`, `slug`, `snippet` (HTML with `<mark>` highlights), `score`.
|
||||
|
||||
### Search page
|
||||
|
||||
```astro
|
||||
---
|
||||
import LiveSearch from "emdash/ui/search";
|
||||
import Base from "../layouts/Base.astro";
|
||||
|
||||
const query = Astro.url.searchParams.get("q") || "";
|
||||
---
|
||||
<Base title="Search">
|
||||
<h1>Search</h1>
|
||||
<LiveSearch
|
||||
placeholder="Search posts..."
|
||||
collections={["posts", "pages"]}
|
||||
/>
|
||||
</Base>
|
||||
```
|
||||
|
||||
### Keyboard shortcut
|
||||
|
||||
Add Cmd+K / Ctrl+K to focus search:
|
||||
|
||||
```html
|
||||
<script>
|
||||
document.addEventListener("keydown", (e) => {
|
||||
if ((e.metaKey || e.ctrlKey) && e.key === "k") {
|
||||
e.preventDefault();
|
||||
document.querySelector(".site-search-input")?.focus();
|
||||
}
|
||||
});
|
||||
</script>
|
||||
```
|
||||
|
||||
### Search prerequisites
|
||||
|
||||
Search requires per-collection enablement:
|
||||
|
||||
1. In admin: Edit Content Type -> check "Search" in Features
|
||||
2. Mark fields as `"searchable": true` in the seed file
|
||||
3. Only searchable fields of searchable collections are indexed
|
||||
|
||||
## SEO Meta
|
||||
|
||||
Generate SEO meta from content entries:
|
||||
|
||||
```typescript
|
||||
import { getSeoMeta } from "emdash";
|
||||
|
||||
const seo = getSeoMeta(post, {
|
||||
siteTitle: "My Blog",
|
||||
siteUrl: Astro.url.origin,
|
||||
path: `/posts/${slug}`,
|
||||
defaultOgImage: featuredImageUrl, // Optional fallback
|
||||
});
|
||||
|
||||
// Returns: { title, description, canonical, ogImage, robots }
|
||||
```
|
||||
|
||||
Use in your layout's `<head>`:
|
||||
|
||||
```astro
|
||||
<title>{seo.title}</title>
|
||||
<meta name="description" content={seo.description} />
|
||||
<link rel="canonical" href={seo.canonical} />
|
||||
<meta property="og:image" content={seo.ogImage} />
|
||||
{seo.robots && <meta name="robots" content={seo.robots} />}
|
||||
```
|
||||
|
||||
## Comments
|
||||
|
||||
Built-in comments system:
|
||||
|
||||
```astro
|
||||
---
|
||||
import { Comments, CommentForm } from "emdash/ui";
|
||||
---
|
||||
<Comments collection="posts" contentId={post.data.id} threaded />
|
||||
<CommentForm collection="posts" contentId={post.data.id} />
|
||||
```
|
||||
|
||||
Comments are enabled per-collection in the seed: `"commentsEnabled": true`.
|
||||
|
||||
## Page Contributions (Plugin Head/Body Injection)
|
||||
|
||||
Plugins can inject content into the `<head>` and `<body>` of pages. To support this, use the page contribution components:
|
||||
|
||||
```astro
|
||||
---
|
||||
import { EmDashHead, EmDashBodyStart, EmDashBodyEnd } from "emdash/ui";
|
||||
import { createPublicPageContext } from "emdash/page";
|
||||
|
||||
const pageCtx = createPublicPageContext({
|
||||
Astro,
|
||||
kind: content ? "content" : "custom",
|
||||
pageType: "article",
|
||||
title: fullTitle,
|
||||
pageTitle: post.data.title,
|
||||
description,
|
||||
canonical,
|
||||
image,
|
||||
content: { collection: "posts", id: post.data.id, slug },
|
||||
});
|
||||
---
|
||||
<html>
|
||||
<head>
|
||||
<!-- your meta tags -->
|
||||
<EmDashHead page={pageCtx} />
|
||||
</head>
|
||||
<body>
|
||||
<EmDashBodyStart page={pageCtx} />
|
||||
<!-- your content -->
|
||||
<EmDashBodyEnd page={pageCtx} />
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
|
||||
This enables plugins (analytics, tracking pixels, structured data, etc.) to contribute to any page.
|
||||
|
||||
## Bylines
|
||||
|
||||
Bylines are author profiles, independent of user accounts. They support guest authors and multi-author attribution with role labels.
|
||||
|
||||
### Eagerly loaded on entries
|
||||
|
||||
Bylines are automatically attached to every entry by the query layer:
|
||||
|
||||
```astro
|
||||
{/* Primary author */}
|
||||
{post.data.byline && (
|
||||
<span>{post.data.byline.displayName}</span>
|
||||
)}
|
||||
|
||||
{/* All credits (includes roleLabel for co-authors, guest essays, etc.) */}
|
||||
{post.data.bylines?.map(credit => (
|
||||
<span>
|
||||
{credit.byline.displayName}
|
||||
{credit.roleLabel && <em> ({credit.roleLabel})</em>}
|
||||
</span>
|
||||
))}
|
||||
```
|
||||
|
||||
- `entry.data.byline` -- primary `BylineSummary` or `null`
|
||||
- `entry.data.bylines` -- array of `ContentBylineCredit` (each has `.byline`, `.roleLabel`, `.source`)
|
||||
|
||||
### Standalone query functions
|
||||
|
||||
```typescript
|
||||
import { getByline, getBylineBySlug } from "emdash";
|
||||
|
||||
// Look up a specific byline
|
||||
const byline = await getBylineBySlug("jane-doe");
|
||||
```
|
||||
|
||||
### BylineSummary shape
|
||||
|
||||
```typescript
|
||||
interface BylineSummary {
|
||||
id: string;
|
||||
slug: string;
|
||||
displayName: string;
|
||||
bio: string | null;
|
||||
avatarMediaId: string | null;
|
||||
websiteUrl: string | null;
|
||||
isGuest: boolean;
|
||||
}
|
||||
```
|
||||
|
||||
### ContentBylineCredit shape
|
||||
|
||||
```typescript
|
||||
interface ContentBylineCredit {
|
||||
byline: BylineSummary;
|
||||
sortOrder: number;
|
||||
roleLabel: string | null; // e.g., "Guest essay", "Photographer"
|
||||
source?: "explicit" | "inferred"; // "inferred" = fallback from author_id
|
||||
}
|
||||
```
|
||||
|
||||
## Dark Mode Pattern
|
||||
|
||||
Cookie-based theme switching (no flash on load):
|
||||
|
||||
```html
|
||||
<!-- In <head>, before styles load -->
|
||||
<script is:inline>
|
||||
(function () {
|
||||
var c = document.cookie;
|
||||
var i = c.indexOf("theme=");
|
||||
var theme = i >= 0 ? c.slice(i + 6).split(";")[0] : null;
|
||||
if (theme === "dark" || theme === "light") {
|
||||
document.documentElement.classList.add(theme);
|
||||
} else if (window.matchMedia("(prefers-color-scheme: dark)").matches) {
|
||||
document.documentElement.classList.add("dark");
|
||||
}
|
||||
})();
|
||||
</script>
|
||||
```
|
||||
|
||||
Then use CSS variables that change based on `.dark` class:
|
||||
|
||||
```css
|
||||
:root {
|
||||
--color-bg: #ffffff;
|
||||
--color-text: #1a1a1a;
|
||||
}
|
||||
:root.dark {
|
||||
--color-bg: #0d0d0d;
|
||||
--color-text: #ededed;
|
||||
}
|
||||
```
|
||||
|
||||
## Layout Pattern
|
||||
|
||||
A typical base layout:
|
||||
|
||||
```astro
|
||||

||||
import { getMenu, getEmDashCollection } from "emdash";
|
||||
import { WidgetArea, EmDashHead, EmDashBodyStart, EmDashBodyEnd } from "emdash/ui";

content?: { collection: string; id: string; slug?: string | null };
|

}
|
||||
|
||||
const { title, pageTitle, description, image, content } = Astro.props;
|
||||
const menu = await getMenu("primary");

# Creating EmDash Plugins
|
||||
|
||||
EmDash plugins extend the CMS with hooks, storage, settings, admin UI, API routes, and custom Portable Text block types. All plugins are TypeScript packages.
|
||||
|
||||
## Plugin Types
|
||||
|
||||
EmDash has two plugin formats:
|
||||
|
||||
| Type | Format | Admin UI | Where it runs |
|
||||
| ------------ | ------------------------------------------------------- | ------------------ | ------------------------------------------- |
|
||||
| **Standard** | `definePlugin({ hooks, routes })` | Block Kit | Isolate on Cloudflare, in-process elsewhere |
|
||||
| **Native** | `createPlugin()` / `definePlugin()` with `id`+`version` | React or Block Kit | Always in host isolate |
|
||||
|
||||
**Standard is the default.** Most plugins should use it. Standard plugins can be published to the marketplace and work in both trusted and sandboxed modes.
|
||||
|
||||
**Native is an escape hatch** for plugins that need React admin components, direct DB access, or custom Astro components. Native plugins can only run in `plugins: []` -- they cannot be sandboxed or published to the marketplace.
|
||||
|
||||
## Plugin Anatomy
|
||||
|
||||
Every plugin has two parts that **run in different contexts**:
|
||||
|
||||
1. **Plugin descriptor** (`PluginDescriptor`) — returned by the factory function in `index.ts`. Declares metadata (id, version, capabilities, storage). **Runs at build time in Vite** (imported in `astro.config.mjs`). Must be side-effect-free.
|
||||
2. **Plugin definition** (`definePlugin()`) — contains the runtime logic (hooks, routes). **Runs at request time on the deployed server.** Has access to the full plugin context (`ctx`). Lives in a separate file (typically `sandbox-entry.ts`).
|
||||
|
||||
These must be in **separate entrypoints** because they execute in completely different environments:
|
||||
|
||||
```
|
||||
my-plugin/
|
||||
├── src/
|
||||
│ ├── index.ts # Descriptor factory (runs in Vite at build time)
|
||||
│ ├── sandbox-entry.ts # Plugin definition with definePlugin() (runs at deploy time)
|
||||
│ ├── admin.tsx # Admin UI exports (React) — optional, native only
|
||||
│ └── astro/ # Site-side rendering components — optional, native only
|
||||
│ └── index.ts # Must export `blockComponents`
|
||||
├── package.json
|
||||
└── tsconfig.json
|
||||
```
|
||||
|
||||
## Minimal Plugin (Standard Format)
|
||||
|
||||
The simplest possible plugin -- just hooks:
|
||||
|
||||
```typescript
|
||||
// src/index.ts — descriptor factory, runs in Vite at build time
|
||||
import type { PluginDescriptor } from "emdash";
|
||||
|
||||
export function myPlugin(): PluginDescriptor {
|
||||
return {
|
||||
id: "my-plugin",
|
||||
version: "1.0.0",
|
||||
format: "standard",
|
||||
entrypoint: "@my-org/my-plugin/sandbox",
|
||||
options: {},
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
```typescript
|
||||
// src/sandbox-entry.ts — plugin definition, runs at request time
|
||||
import { definePlugin } from "emdash";
|
||||
import type { PluginContext } from "emdash";
|
||||
|
||||
export default definePlugin({
|
||||
hooks: {
|
||||
"content:afterSave": {
|
||||
handler: async (event: any, ctx: PluginContext) => {
|
||||
ctx.log.info(`Saved ${event.collection}/${event.content.id}`);
|
||||
},
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
The descriptor is what gets imported in `astro.config.mjs`. The `entrypoint` field points to the module containing the `definePlugin()` default export. For standard plugins, this is the `./sandbox` export from `package.json`.
|
||||
|
||||
Key differences from native format:
|
||||
|
||||
- No `id`, `version`, or `capabilities` in `definePlugin()` -- those live in the descriptor
|
||||
- `definePlugin()` is an identity function providing type inference
|
||||
- Hook handlers use `(event, ctx)` two-arg pattern
|
||||
- Route handlers use `(routeCtx, ctx)` two-arg pattern
|
||||
- Exported as `default` (not a factory function)
|
||||
|
||||
## Plugin ID Rules
|
||||
|
||||
- Lowercase alphanumeric + hyphens only
|
||||
- Simple (`my-plugin`) or scoped (`@my-org/my-plugin`)
|
||||
- Unique across all installed plugins
|
||||
|
||||
## Registration
|
||||
|
||||
The descriptor is imported in `astro.config.mjs` (Vite context):
|
||||
|
||||
```typescript
|
||||
import { myPlugin } from "@my-org/my-plugin";
|
||||
|
||||
export default defineConfig({
|
||||
integrations: [
|
||||
emdash({
|
||||
plugins: [myPlugin()], // runs in-process
|
||||
// OR
|
||||
sandboxed: [myPlugin()], // runs in isolate on Cloudflare
|
||||
}),
|
||||
],
|
||||
});
|
||||
```
|
||||
|
||||
Standard plugins work in either array. Native plugins only work in `plugins: []`.
|
||||
|
||||
## Trusted vs Sandboxed Plugins
|
||||
|
||||
EmDash has two execution modes. Plugin code is identical in both — only the enforcement changes.
|
||||
|
||||
| | Trusted | Sandboxed |
|
||||
| ------------------- | ----------------------------------------- | ------------------------------------------------------ |
|
||||
| **Runs in** | Main process | Isolated V8 isolate (Dynamic Worker Loader) |
|
||||
| **Install method** | `astro.config.mjs` (code change + deploy) | Admin UI (one-click from marketplace) |
|
||||
| **Capabilities** | Advisory (not enforced) | Enforced at runtime via RPC bridge |
|
||||
| **Resource limits** | None | CPU 50ms, 10 subrequests, 30s wall-time, ~128MB memory |
|
||||
| **Network access** | Unrestricted | Blocked; only via `ctx.http` with `allowedHosts` |
|
||||
| **Data access** | Full database access | Scoped to declared capabilities |
|
||||
| **Node.js APIs** | Full access | Not available (V8 isolate only) |
|
||||
| **Available on** | All platforms | Cloudflare Workers only |
|
||||
| **Best for** | First-party code, reviewed npm packages | Third-party extensions, marketplace plugins |
|
||||
|
||||
### Trusted Mode
|
||||
|
||||
Trusted plugins are npm packages or local files added in `astro.config.mjs`. They run in-process with your Astro site.
|
||||
|
||||
- **Capabilities are documentation only.** Declaring `["read:content"]` documents intent but isn't enforced — the plugin has full process access.
|
||||
- Only install from sources you trust. A malicious trusted plugin has the same access as your application code.
|
||||
|
||||
### Sandboxed Mode
|
||||
|
||||
Sandboxed plugins run in isolated V8 isolates on Cloudflare Workers via [Dynamic Worker Loader](https://developers.cloudflare.com/workers/runtime-apis/bindings/worker-loader/). Each plugin gets its own isolate.
|
||||
|
||||
- **Capabilities are enforced.** If a plugin declares `["read:content"]`, it can only call `ctx.content.get()` and `ctx.content.list()`. Attempting `ctx.content.create()` throws a permission error.
|
||||
- **Network is blocked by default.** Direct `fetch()` calls fail. Plugins must use `ctx.http.fetch()`, which validates against `allowedHosts`.
|
||||
- **Storage is scoped.** A plugin can only access its own KV and storage collections.
|
||||
- **Admin UI uses Block Kit.** Sandboxed plugins describe their UI as JSON blocks -- no plugin JavaScript runs in the browser. See [Block Kit reference](./references/block-kit.md).
|
||||
- **No Portable Text block types.** PT blocks require Astro components for site-side rendering (`componentsEntry`), which are loaded at build time from npm. Sandboxed plugins are installed at runtime and can't ship components. PT blocks are a native-plugin-only feature.
|
||||
- **Routes work.** Standard plugin routes are available in both trusted and sandboxed modes via the sandbox runner's `invokeRoute()` RPC.
|
||||
|
||||
Sandboxing is not available on Node.js. All plugins run in trusted mode on non-Cloudflare platforms.
|
||||
|
||||
### Developing for Both Modes
|
||||
|
||||
Write the same code. Develop locally in trusted mode (faster iteration, easier debugging). Deploy to sandboxed mode in production without code changes. With the standard format, the same entrypoint serves both modes -- no separate sandbox entry needed.
|
||||
|
||||
```typescript
|
||||
// src/sandbox-entry.ts -- works in both trusted and sandboxed modes
|
||||
import { definePlugin } from "emdash";
|
||||
import type { PluginContext } from "emdash";
|
||||
|
||||
export default definePlugin({
|
||||
hooks: {
|
||||
"content:afterSave": {
|
||||
handler: async (event: any, ctx: PluginContext) => {
|
||||
// Trusted: ctx.http present because descriptor declares network:fetch
|
||||
// Sandboxed: ctx.http present and enforced via RPC bridge
|
||||
if (!ctx.http) return;
|
||||
await ctx.http.fetch("https://api.analytics.example.com/track", {
|
||||
method: "POST",
|
||||
body: JSON.stringify({ contentId: event.content.id }),
|
||||
});
|
||||
},
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Key constraint for sandbox compatibility: **no Node.js built-ins** (`fs`, `path`, `child_process`, etc.) in backend code. Use Web APIs instead.
|
||||
|
||||
## Capabilities
|
||||
|
||||
Capabilities control what APIs are available on `ctx`. Always declare what your plugin needs — even in trusted mode, they document intent and are required for sandboxed execution.
|
||||
|
||||
| Capability | Grants | `ctx` property |
|
||||
| ----------------- | ---------------------------------------------------------------------- | -------------- |
|
||||
| `read:content` | `ctx.content.get()`, `ctx.content.list()` | `content` |
|
||||
| `write:content` | `ctx.content.create()`, `ctx.content.update()`, `ctx.content.delete()` | `content` |
|
||||
| `read:media` | `ctx.media.get()`, `ctx.media.list()` | `media` |
|
||||
| `write:media` | `ctx.media.getUploadUrl()`, `ctx.media.delete()` | `media` |
|
||||
| `network:fetch` | `ctx.http.fetch()` (restricted to `allowedHosts`) | `http` |
|
||||
| `read:users` | `ctx.users.get()`, `ctx.users.list()`, `ctx.users.getByEmail()` | `users` |
|
||||
| `email:send` | `ctx.email.send()` — send email through the pipeline | `email` |
|
||||
| `email:provide` | Can register `email:deliver` exclusive hook (transport provider) | — |
|
||||
| `email:intercept` | Can register `email:beforeSend` / `email:afterSend` hooks | — |
|
||||
|
||||
Storage (`ctx.storage`) and KV (`ctx.kv`) are **always available** — no capability needed. They're automatically scoped to the plugin.
|
||||
|
||||
**Email capabilities are distinct:**
|
||||
|
||||
- `email:send` — for plugins that _consume_ email (call `ctx.email.send()`)
|
||||
- `email:provide` — for plugins that _deliver_ email (implement the transport, e.g. Resend, SMTP)
|
||||
- `email:intercept` — for plugins that _observe or transform_ email (middleware hooks)
|
||||
|
||||
```typescript
|
||||
// In the descriptor (index.ts)
|
||||
export function myPlugin(): PluginDescriptor {
|
||||
return {
|
||||
id: "my-plugin",
|
||||
version: "1.0.0",
|
||||
format: "standard",
|
||||
entrypoint: "@my-org/my-plugin/sandbox",
|
||||
options: {},
|
||||
capabilities: ["read:content", "network:fetch"],
|
||||
allowedHosts: ["api.example.com", "*.googleapis.com"], // Wildcards supported
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
When a marketplace plugin is installed, the admin sees a capability consent dialog listing what the plugin can access. Users must approve before installation.
|
||||
|
||||
## Publishing to the Marketplace
|
||||
|
||||
Standard plugins can be published to the EmDash Marketplace for one-click installation:
|
||||
|
||||
```bash
|
||||
emdash plugin bundle --dir packages/plugins/my-plugin # creates .tar.gz
|
||||
emdash plugin login # authenticate via GitHub
|
||||
emdash plugin publish --tarball dist/my-plugin-1.0.0.tar.gz
|
||||
```
|
||||
|
||||
See [Publishing Reference](./references/publishing.md) for bundle format, validation, and security audit details.
|
||||
|
||||
## Package Exports
|
||||
|
||||
Configure `package.json` exports so EmDash can load each entry point:
|
||||
|
||||
```json
|
||||
{
|
||||
"name": "@my-org/my-plugin",
|
||||
"type": "module",
|
||||
"exports": {
|
||||
".": "./src/index.ts",
|
||||
"./sandbox": "./src/sandbox-entry.ts",
|
||||
"./admin": "./src/admin.tsx"
|
||||
},
|
||||
"peerDependencies": {
|
||||
"emdash": "^0.1.0"
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
| Export | Context | Purpose |
|
||||
| ------------- | ----------------- | ---------------------------------------------------------------------- |
|
||||
| `"."` | Vite (build time) | Descriptor factory -- imported in `astro.config.mjs` |
|
||||
| `"./sandbox"` | Server (runtime) | `definePlugin({ hooks, routes })` -- loaded by `entrypoint` at runtime |
|
||||
| `"./admin"` | Browser | React components for admin pages/widgets (native plugins only) |
|
||||
| `"./astro"` | Server (SSR) | Astro components for site-side block rendering (native plugins only) |
|
||||
|
||||
The `"."` export has the descriptor. The `"./sandbox"` export has the implementation. The descriptor's `entrypoint` field points to `"./sandbox"`. Only include `./admin` and `./astro` exports for native-format plugins.
|
||||
|
||||
## Plugin Features
|
||||
|
||||
Each feature is optional. Add only what your plugin needs:
|
||||
|
||||
| Feature | Where | Standard | Native | Purpose |
|
||||
| ------------------- | ---------------------------- | -------- | ------ | ----------------------------------------------------- |
|
||||
| **Hooks** | `definePlugin({ hooks })` | Yes | Yes | React to content/media/lifecycle events |
|
||||
| **Storage** | descriptor `storage` | Yes | Yes | Document collections with indexed queries |
|
||||
| **KV** | `ctx.kv` in hooks/routes | Yes | Yes | Key-value store for internal state |
|
||||
| **API Routes** | `definePlugin({ routes })` | Yes | Yes | REST endpoints at `/_emdash/api/plugins/<id>/<route>` |
|
||||
| **Admin Pages** | Block Kit `admin` route | Yes | Yes | Admin pages via Block Kit (JSON blocks) |
|
||||
| **Widgets** | Block Kit `admin` route | Yes | Yes | Dashboard cards via Block Kit |
|
||||
| **React Admin** | `admin.entry` + React export | No | Yes | React-based admin pages and widgets (native only) |
|
||||
| **PT Blocks** | `admin.portableTextBlocks` | No | Yes | Custom block types in the Portable Text editor |
|
||||
| **Site Components** | `componentsEntry` | No | Yes | Astro components for rendering blocks on the site |
|
||||
|
||||

|
||||
return { blocks: [] };
|
||||
},
|
||||

|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
## Plugin Context
|
||||
|
||||
All hooks and routes receive `ctx` (PluginContext):
|
||||
|
||||
```typescript
|
||||
interface PluginContext {
|
||||
plugin: { id: string; version: string };
|
||||
storage: Record<string, StorageCollection>; // Declared collections
|
||||
kv: KVAccess; // Key-value store
|
||||
log: LogAccess; // Structured logger
|
||||
content?: ContentAccess; // If "read:content" capability
|
||||
media?: MediaAccess; // If "read:media" capability
|
||||
http?: HttpAccess; // If "network:fetch" capability
|
||||
users?: UserAccess; // If "read:users" capability
|
||||
cron?: CronAccess; // Always available — scoped to plugin
|
||||
email?: EmailAccess; // If "email:send" capability AND a provider is configured
|
||||
}
|
||||
```
|
||||
|
||||
Capabilities are declared in the **descriptor** (not in `definePlugin()` for standard format):
|
||||
|
||||
```typescript
|
||||
// In the descriptor
|
||||
export function myPlugin(): PluginDescriptor {
|
||||
return {
|
||||
id: "my-plugin",
|
||||
version: "1.0.0",
|
||||
format: "standard",
|
||||
entrypoint: "@my-org/my-plugin/sandbox",
|
||||
options: {},
|
||||
capabilities: ["read:content", "network:fetch"],
|
||||
allowedHosts: ["api.example.com"],
|
||||
storage: { events: { indexes: ["timestamp"] } },
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
## Output Checklist
|
||||
|
||||
When creating a standard-format plugin, provide:
|
||||
|
||||
1. **`src/index.ts`** -- Descriptor factory (runs in Vite at build time)
|
||||
2. **`src/sandbox-entry.ts`** -- `definePlugin({ hooks, routes })` as default export (runs at request time)
|
||||
3. **`package.json`** -- With exports `"."` (descriptor) and `"./sandbox"` (implementation)
|
||||
4. **`tsconfig.json`** -- Standard TypeScript config
|
||||
|
||||
For native-format plugins (React admin, PT blocks, Astro components), also provide:
|
||||
|
||||
5. **`src/admin.tsx`** -- Admin entry point with React components
|
||||
6. **`src/astro/index.ts`** -- Block components export (if PT blocks)

# Admin UI
|
||||
|
||||
Plugins extend the admin panel with React pages and dashboard widgets.
|
||||
|
||||
## Entry Point
|
||||
|
||||
Export pages and widgets from `src/admin.tsx`:
|
||||
|
||||
```typescript
|
||||
// src/admin.tsx
|
||||
import { SettingsPage } from "./components/SettingsPage";
|
||||
import { ReportsPage } from "./components/ReportsPage";
|
||||
import { StatusWidget } from "./components/StatusWidget";
|
||||
|
||||
// Pages keyed by path (must match admin.pages paths)
|
||||
export const pages = {
|
||||
"/settings": SettingsPage,
|
||||
"/reports": ReportsPage,
|
||||
};
|
||||
|
||||
// Widgets keyed by ID (must match admin.widgets IDs)
|
||||
export const widgets = {
|
||||
status: StatusWidget,
|
||||
};
|
||||
```
|
||||
|
||||
Reference in plugin definition:
|
||||
|
||||
```typescript
|
||||
definePlugin({
|
||||
id: "my-plugin",
|
||||
version: "1.0.0",
|
||||
|
||||
admin: {
|
||||
entry: "@my-org/my-plugin/admin",
|
||||
pages: [
|
||||
{ path: "/settings", label: "Settings", icon: "settings" },
|
||||
{ path: "/reports", label: "Reports", icon: "chart" },
|
||||
],
|
||||
widgets: [{ id: "status", title: "Status", size: "half" }],
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Pages mount at `/_emdash/admin/plugins/<plugin-id>/<path>`.
|
||||
|
||||
## Pages
|
||||
|
||||
React components. Use `usePluginAPI()` to call plugin routes.
|
||||
|
||||
```typescript
|
||||
// src/components/SettingsPage.tsx
|
||||
import { useState, useEffect } from "react";
|
||||
import { usePluginAPI } from "@emdash-cms/admin";
|
||||
|
||||
export function SettingsPage() {
|
||||
const api = usePluginAPI();
|
||||
const [settings, setSettings] = useState<Record<string, unknown>>({});
|
||||
const [saving, setSaving] = useState(false);
|
||||
|
||||
useEffect(() => {
|
||||
api.get("settings").then(setSettings);
|
||||
}, []);
|
||||
|
||||
const handleSave = async () => {
|
||||
setSaving(true);
|
||||
await api.post("settings/save", settings);
|
||||
setSaving(false);
|
||||
};
|
||||
|
||||
return (
|
||||
<div>
|
||||
<h1>Settings</h1>
|
||||
<label>
|
||||
Site Title
|
||||
<input
|
||||
type="text"
|
||||
value={settings.siteTitle || ""}
|
||||
onChange={(e) => setSettings({ ...settings, siteTitle: e.target.value })}
|
||||
/>
|
||||
</label>
|
||||
<button onClick={handleSave} disabled={saving}>
|
||||
{saving ? "Saving..." : "Save"}
|
||||
</button>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
## Widgets
|
||||
|
||||
Dashboard cards with at-a-glance info.
|
||||
|
||||
```typescript
|
||||
// src/components/StatusWidget.tsx
|
||||
import { useState, useEffect } from "react";
|
||||
import { usePluginAPI } from "@emdash-cms/admin";
|
||||
|
||||
export function StatusWidget() {
|
||||
const api = usePluginAPI();
|
||||
const [data, setData] = useState({ count: 0 });
|
||||
|
||||
useEffect(() => {
|
||||
api.get("status").then(setData);
|
||||
}, []);
|
||||
|
||||
return (
|
||||
<div className="widget-content">
|
||||
<div className="score">{data.count}</div>
|
||||
</div>
|
||||
);
|
||||
}
|
||||
```
|
||||
|
||||
### Widget Sizes
|
||||
|
||||
| Size | Width |
|
||||
| ------- | -------------------- |
|
||||
| `full` | Full dashboard width |
|
||||
| `half` | Half width |
|
||||
| `third` | One-third width |
|
||||
|
||||
## usePluginAPI()
|
||||
|
||||
Auto-prefixes plugin ID to route URLs:
|
||||
|
||||
```typescript
|
||||
const api = usePluginAPI();
|
||||
|
||||
const data = await api.get("status"); // GET /.../plugins/<id>/status
|
||||
await api.post("settings/save", { enabled: true }); // POST with body
|
||||
const result = await api.get("history?limit=50"); // Query params
|
||||
```
|
||||
|
||||
## Admin Components
|
||||
|
||||
Pre-built components from `@emdash-cms/admin`:
|
||||
|
||||
```typescript
|
||||
import { Card, Button, Input, Select, Toggle, Table, Loading, Alert } from "@emdash-cms/admin";
|
||||
```
|
||||
|
||||
## Auto-Generated Settings
|
||||
|
||||
If your plugin only needs settings, skip custom pages — use `settingsSchema` and EmDash generates the form:
|
||||
|
||||
```typescript
|
||||
admin: {
|
||||
settingsSchema: {
|
||||
apiKey: { type: "secret", label: "API Key" },
|
||||
enabled: { type: "boolean", label: "Enabled", default: true },
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Build Configuration
|
||||
|
||||
Admin components need a separate build entry:
|
||||
|
||||
```typescript
|
||||
// tsdown.config.ts
|
||||
export default {
|
||||
entry: {
|
||||
index: "src/index.ts",
|
||||
admin: "src/admin.tsx",
|
||||
},
|
||||
format: "esm",
|
||||
dts: true,
|
||||
external: ["react", "react-dom", "emdash", "@emdash-cms/admin"],
|
||||
};
|
||||
```
|
||||
|
||||
Keep React and `@emdash-cms/admin` as externals to avoid bundling duplicates.
|
||||
|
||||
## Plugin Descriptor
|
||||
|
||||
The descriptor (returned by factory function) also declares admin metadata:
|
||||
|
||||
```typescript
|
||||
export function myPlugin(options = {}): PluginDescriptor {
|
||||
return {
|
||||
id: "my-plugin",
|
||||
entrypoint: "@my-org/my-plugin",
|
||||
version: "1.0.0",
|
||||
options,
|
||||
adminEntry: "@my-org/my-plugin/admin",
|
||||
adminPages: [{ path: "/settings", label: "Settings", icon: "settings" }],
|
||||
adminWidgets: [{ id: "status", title: "Status", size: "half" }],
|
||||
};
|
||||
}
|

# API Routes
|
||||
|
||||
Plugin routes work in both standard and native plugins, and in both trusted and sandboxed modes. Sandboxed plugin routes are invoked via the sandbox runner's `invokeRoute()` RPC.
|
||||
|
||||
Plugin routes expose REST endpoints at `/_emdash/api/plugins/<plugin-id>/<route-name>`.
|
||||
|
||||
## Defining Routes
|
||||
|
||||
```typescript
|
||||
import { definePlugin } from "emdash";
|
||||
import { z } from "astro/zod";
|
||||
|
||||
definePlugin({
|
||||
id: "forms",
|
||||
version: "1.0.0",
|
||||
|
||||
routes: {
|
||||
// Simple route
|
||||
status: {
|
||||
handler: async (ctx) => {
|
||||
return { ok: true };
|
||||
},
|
||||
},
|
||||
|
||||
// Route with input validation
|
||||
submissions: {
|
||||
input: z.object({
|
||||
formId: z.string().optional(),
|
||||
limit: z.number().default(50),
|
||||
cursor: z.string().optional(),
|
||||
}),
|
||||
handler: async (ctx) => {
|
||||
const { formId, limit, cursor } = ctx.input;
|
||||
const result = await ctx.storage.submissions!.query({
|
||||
where: formId ? { formId } : undefined,
|
||||
orderBy: { createdAt: "desc" },
|
||||
limit,
|
||||
cursor,
|
||||
});
|
||||
return {
|
||||
items: result.items,
|
||||
cursor: result.cursor,
|
||||
hasMore: result.hasMore,
|
||||
};
|
||||
},
|
||||
},
|
||||
|
||||
// Nested path
|
||||
"settings/save": {
|
||||
input: z.object({
|
||||
enabled: z.boolean().optional(),
|
||||
apiKey: z.string().optional(),
|
||||
}),
|
||||
handler: async (ctx) => {
|
||||
for (const [key, value] of Object.entries(ctx.input)) {
|
||||
if (value !== undefined) {
|
||||
await ctx.kv.set(`settings:${key}`, value);
|
||||
}
|
||||
}
|
||||
return { success: true };
|
||||
},
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
## Route URLs
|
||||
|
||||
| Plugin ID | Route Name | URL |
|
||||
| --------- | --------------- | ---------------------------------------- |
|
||||
| `forms` | `status` | `/_emdash/api/plugins/forms/status` |
|
||||
| `forms` | `submissions` | `/_emdash/api/plugins/forms/submissions` |
|
||||
| `seo` | `settings/save` | `/_emdash/api/plugins/seo/settings/save` |
|
||||
|
||||
## Handler Context
|
||||
|
||||
```typescript
|
||||
interface RouteContext<TInput = unknown> extends PluginContext {
|
||||
input: TInput; // Validated input
|
||||
request: Request; // Original request
|
||||
plugin: { id: string; version: string };
|
||||
storage: Record<string, StorageCollection>;
|
||||
kv: KVAccess;
|
||||
content?: ContentAccess; // If capability declared
|
||||
media?: MediaAccess;
|
||||
http?: HttpAccess;
|
||||
log: LogAccess;
|
||||
}
|
||||
```
|
||||
|
||||
## Input Validation
|
||||
|
||||
Use Zod schemas. Invalid input returns 400.
|
||||
|
||||
```typescript
|
||||
routes: {
|
||||
create: {
|
||||
input: z.object({
|
||||
title: z.string().min(1).max(200),
|
||||
email: z.string().email(),
|
||||
priority: z.enum(["low", "medium", "high"]).default("medium"),
|
||||
tags: z.array(z.string()).optional(),
|
||||
}),
|
||||
handler: async (ctx) => {
|
||||
// ctx.input is typed and validated
|
||||
const { title, email, priority } = ctx.input;
|
||||
// ...
|
||||
},
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
Input sources:
|
||||
|
||||
- **POST/PUT/PATCH** — Request body (JSON)
|
||||
- **GET/DELETE** — URL query parameters
|
||||
|
||||
## Return Values
|
||||
|
||||
Return any JSON-serializable value. Response is always `Content-Type: application/json`.
|
||||
|
||||
```typescript
|
||||
return { success: true, data: items }; // Object
|
||||
return items; // Array
|
||||
return 42; // Primitive
|
||||
```
|
||||
|
||||
## Errors
|
||||
|
||||
Throw to return error response:
|
||||
|
||||
```typescript
|
||||
throw new Error("Item not found"); // 500 with { error: "Item not found" }
|
||||
|
||||
// Custom status code
|
||||
throw new Response(JSON.stringify({ error: "Not found" }), {
|
||||
status: 404,
|
||||
headers: { "Content-Type": "application/json" },
|
||||
});
|
||||
```
|
||||
|
||||
## HTTP Methods
|
||||
|
||||
Routes respond to all methods. Check `ctx.request.method`:
|
||||
|
||||
```typescript
|
||||
handler: async (ctx) => {
|
||||
switch (ctx.request.method) {
|
||||
case "GET":
|
||||
return await ctx.storage.items!.get(ctx.input.id);
|
||||
case "DELETE":
|
||||
await ctx.storage.items!.delete(ctx.input.id);
|
||||
return { deleted: true };
|
||||
default:
|
||||
throw new Response("Method not allowed", { status: 405 });
|
||||
}
|
||||
};
|
||||
```
|
||||
|
||||
## Common Patterns
|
||||
|
||||
### Settings CRUD
|
||||
|
||||
```typescript
|
||||
routes: {
|
||||
settings: {
|
||||
handler: async (ctx) => {
|
||||
const settings = await ctx.kv.list("settings:");
|
||||
const result: Record<string, unknown> = {};
|
||||
for (const entry of settings) {
|
||||
result[entry.key.replace("settings:", "")] = entry.value;
|
||||
}
|
||||
return result;
|
||||
},
|
||||
},
|
||||
"settings/save": {
|
||||
handler: async (ctx) => {
|
||||
const input = await ctx.request.json();
|
||||
for (const [key, value] of Object.entries(input)) {
|
||||
if (value !== undefined) await ctx.kv.set(`settings:${key}`, value);
|
||||
}
|
||||
return { success: true };
|
||||
},
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
### Paginated List
|
||||
|
||||
```typescript
|
||||
routes: {
|
||||
list: {
|
||||
input: z.object({
|
||||
limit: z.number().min(1).max(100).default(50),
|
||||
cursor: z.string().optional(),
|
||||
status: z.string().optional(),
|
||||
}),
|
||||
handler: async (ctx) => {
|
||||
const { limit, cursor, status } = ctx.input;
|
||||
const result = await ctx.storage.items!.query({
|
||||
where: status ? { status } : undefined,
|
||||
orderBy: { createdAt: "desc" },
|
||||
limit,
|
||||
cursor,
|
||||
});
|
||||
return {
|
||||
items: result.items.map((item) => ({ id: item.id, ...item.data })),
|
||||
cursor: result.cursor,
|
||||
hasMore: result.hasMore,
|
||||
};
|
||||
},
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
### External API Proxy
|
||||
|
||||
Requires `network:fetch` capability and `allowedHosts`:
|
||||
|
||||
```typescript
|
||||
definePlugin({
|
||||
capabilities: ["network:fetch"],
|
||||
allowedHosts: ["api.weather.example.com"],
|
||||
|
||||
routes: {
|
||||
forecast: {
|
||||
input: z.object({ city: z.string() }),
|
||||
handler: async (ctx) => {
|
||||
const apiKey = await ctx.kv.get<string>("settings:apiKey");
|
||||
if (!apiKey) throw new Error("API key not configured");
|
||||
|
||||
const response = await ctx.http!.fetch(
|
||||
`https://api.weather.example.com/forecast?city=${ctx.input.city}`,
|
||||
{ headers: { "X-API-Key": apiKey } },
|
||||
);
|
||||
|
||||
if (!response.ok) throw new Error(`API error: ${response.status}`);
|
||||
return response.json();
|
||||
},
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
## Calling from Admin UI
|
||||
|
||||
```typescript
|
||||
import { usePluginAPI } from "@emdash-cms/admin";
|
||||
|
||||
const api = usePluginAPI();
|
||||
const data = await api.get("status");
|
||||
await api.post("settings/save", { enabled: true });
|
||||
```
|
||||
|
||||
## Calling Externally
|
||||
|
||||
```bash
|
||||
curl https://your-site.com/_emdash/api/plugins/forms/submissions?limit=10
|
||||
|
||||
curl -X POST https://your-site.com/_emdash/api/plugins/forms/create \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"title": "Hello"}'
|
||||
```
|
||||
|
||||
Plugin routes don't have built-in auth. Admin-only routes are protected by the admin session middleware.

# Block Kit
|
||||
|
||||
Declarative JSON UI for sandboxed plugin admin pages. The host renders blocks — no plugin JavaScript runs in the browser. Inspired by Slack's Block Kit but not identical — similar concepts and naming, different block/element types and capabilities.
|
||||
|
||||
Trusted plugins (declared in `astro.config.ts`) can ship custom React components instead. Block Kit is for runtime-installed sandboxed plugins.
|
||||
|
||||
Block Kit elements are also used for [Portable Text block editing fields](./portable-text-blocks.md). When a plugin declares `fields` on a block type, the editor renders a Block Kit form.
|
||||
|
||||
## How It Works
|
||||
|
||||
1. User navigates to plugin admin page
|
||||
2. Admin sends `page_load` interaction to plugin's admin route
|
||||
3. Plugin returns `BlockResponse` with array of blocks
|
||||
4. Admin renders blocks using `BlockRenderer`
|
||||
5. User interacts (button click, form submit) → interaction sent back
|
||||
6. Plugin returns new blocks
|
||||
|
||||
```typescript
|
||||
routes: {
|
||||
admin: {
|
||||
handler: async (ctx) => {
|
||||
const interaction = await ctx.request.json();
|
||||
|
||||
if (interaction.type === "page_load") {
|
||||
return {
|
||||

],
|
||||
submit: { label: "Save", action_id: "save" },
|
||||
},
|
||||
],
|
||||
};
|
||||
}
|
||||
|
||||
if (interaction.type === "form_submit" && interaction.action_id === "save") {
|
||||
await ctx.kv.set("settings", interaction.values);
|
||||
return {
|
||||
blocks: [/* updated blocks */],
|

# Hooks Reference
|
||||
|
||||
Hooks let plugins run code in response to events. Declared in `definePlugin({ hooks })`.
|
||||
|
||||
## Signature
|
||||
|
||||
```typescript
|
||||
async (event: EventType, ctx: PluginContext) => ReturnType;
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
Simple handler or full config:
|
||||
|
||||
```typescript
|
||||
// Simple
|
||||
hooks: {
|
||||
"content:afterSave": async (event, ctx) => {
|
||||
ctx.log.info("Saved");
|
||||
}
|
||||
}
|
||||
|
||||
// Full config
|
||||
hooks: {
|
||||
"content:afterSave": {
|
||||
priority: 100, // Lower runs first (default: 100)
|
||||
timeout: 5000, // Max execution time ms (default: 5000)
|
||||
dependencies: [], // Plugin IDs that must run first
|
||||
errorPolicy: "abort", // "abort" | "continue"
|
||||
handler: async (event, ctx) => {
|
||||
ctx.log.info("Saved");
|
||||
}
|
||||
}

"content:afterDelete": async (event, ctx) => {
|
||||
ctx.log.info(`Deleted ${event.collection}/${event.id}`);
|
||||
await ctx.storage.cache!.delete(`${event.collection}:${event.id}`);
|
||||
}
|
||||
```
|
||||
|
||||
Event: `{ id: string, collection: string }`
|
||||
Returns: `void`
|
||||
|
||||
## Media Hooks
|
||||
|
||||
### `media:beforeUpload`
|
||||
|
||||
Runs before upload. Return modified file info, void to keep, or throw to cancel.
|
||||
|
||||
```typescript
|
||||
"media:beforeUpload": async (event, ctx) => {
|
||||
const { file } = event;
|
||||
|
||||
if (!file.type.startsWith("image/")) {
|
||||
throw new Error("Only images allowed");
|
||||
}
|
||||
|
||||
if (file.size > 10 * 1024 * 1024) {
|
||||
throw new Error("Max 10MB");
|
||||
}
|
||||
|
||||
return { ...file, name: `${Date.now()}-${file.name}` };
|
||||
}
|
||||
```
|
||||
|
||||
Event: `{ file: { name: string, type: string, size: number } }`
|
||||
Returns: `{ name: string, type: string, size: number } | void`
|
||||
|
||||
### `media:afterUpload`
|
||||
|
||||
Runs after successful upload.
|
||||
|
||||
```typescript
|
||||
"media:afterUpload": async (event, ctx) => {
|
||||
ctx.log.info(`Uploaded ${event.media.filename}`, { id: event.media.id });
|
||||
}
|
||||
```
|
||||
|
||||
Event: `{ media: { id: string, filename: string, mimeType: string, size: number | null, url: string, createdAt: string } }`
|
||||
Returns: `void`
|
||||
|
||||
## Email Hooks
|
||||
|
||||
Email hooks require specific capabilities. Without the required capability, hooks are silently skipped.
|
||||
|
||||
### `email:beforeSend`
|
||||
|
||||
**Requires:** `email:intercept` capability.
|
||||
|
||||
Runs before email delivery. Return modified message, or `false` to cancel delivery. Handlers are chained — each receives the output of the previous one.
|
||||
|
||||
```typescript
|
||||
definePlugin({
|
||||
id: "email-footer",
|
||||
capabilities: ["email:intercept"],
|
||||
hooks: {
|
||||
"email:beforeSend": async (event, ctx) => {
|
||||
return { ...event.message, text: event.message.text + "\n\n-- Sent via EmDash" };
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Event: `{ message: EmailMessage, source: string }`
|
||||
Returns: `EmailMessage | false`
|
||||
|
||||
### `email:deliver`
|
||||
|
||||
**Requires:** `email:provide` capability. **Exclusive hook** — exactly one provider is active.
|
||||
|
||||
Implements email transport (e.g. Resend, SMTP, SES). Selected by the admin in Settings > Email.
|
||||
|
||||
```typescript
|
||||
definePlugin({
|
||||
id: "emdash-resend",
|
||||
capabilities: ["email:provide", "network:fetch"],
|
||||
allowedHosts: ["api.resend.com"],
|
||||
hooks: {
|
||||
"email:deliver": {
|
||||
exclusive: true,
|
||||
handler: async ({ message }, ctx) => {
|
||||
const apiKey = await ctx.kv.get("settings:apiKey");
|
||||
await ctx.http!.fetch("https://api.resend.com/emails", {
|
||||
method: "POST",
|
||||
headers: { Authorization: `Bearer ${apiKey}` },
|
||||
body: JSON.stringify({ to: message.to, subject: message.subject, text: message.text }),
|
||||
});
|
||||
},
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Event: `{ message: EmailMessage, source: string }`
|
||||
Returns: `void`
|
||||
|
||||
### `email:afterSend`
|
||||
|
||||
**Requires:** `email:intercept` capability.
|
||||
|
||||
Runs after successful delivery. Fire-and-forget — errors are logged but don't propagate.
|
||||
|
||||
```typescript
|
||||
definePlugin({
|
||||
id: "email-logger",
|
||||
capabilities: ["email:intercept"],
|
||||
hooks: {
|
||||
"email:afterSend": async (event, ctx) => {
|
||||
ctx.log.info(`Email sent to ${event.message.to}`, { source: event.source });
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Event: `{ message: EmailMessage, source: string }`
|
||||
Returns: `void`
|
||||
|
||||
## Cron Hook
|
||||
|
||||
### `cron`
|
||||
|
||||
Runs on a schedule. Configure schedules via `ctx.cron.schedule()` in `plugin:activate`.
|
||||
|
||||
```typescript
|
||||
definePlugin({
|
||||
id: "cleanup",
|
||||
hooks: {
|
||||
"plugin:activate": async (_event, ctx) => {
|
||||
await ctx.cron!.schedule("daily-cleanup", { schedule: "0 2 * * *" });
|
||||
},
|
||||
cron: async (event, ctx) => {
|
||||
if (event.name === "daily-cleanup") {
|
||||
// ... cleanup logic
|
||||
}
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Event: `{ name: string, data?: Record<string, unknown> }`
|
||||
Returns: `void`
|
||||
|
||||
## Public Page Hooks
|
||||
|
||||
Public page hooks let plugins contribute to the rendered output of public site pages. Templates opt in to these contributions with `<EmDashHead>`, `<EmDashBodyStart>`, and `<EmDashBodyEnd>` components.
|
||||
|
||||
### `page:metadata`
|
||||
|
||||
Contributes typed metadata to `<head>` — meta tags, OG properties, canonical/alternate links, and JSON-LD. Works in both trusted and sandboxed modes.
|
||||
|
||||
Returns structured contributions that core validates, dedupes (first-wins), and renders. Plugins never emit raw HTML through this hook.
|
||||
|
||||
```typescript
|
||||
"page:metadata": async (event, ctx) => {
|
||||
if (event.page.kind !== "content") return null;
|
||||
|
||||
return [
|
||||
{ kind: "meta", name: "author", content: "My Blog" },
|
||||
{
|
||||
kind: "jsonld",
|
||||
id: `schema:${event.page.content?.collection}:${event.page.content?.id}`,
|
||||
graph: {
|
||||
"@context": "https://schema.org",
|
||||
"@type": "BlogPosting",
|
||||
headline: event.page.pageTitle ?? event.page.title,
|
||||
description: event.page.description,
|
||||
},
|
||||
},
|
||||
];
|
||||
}
|
||||
```
|
||||
|
||||
Event: `{ page: PublicPageContext }`
|
||||
Returns: `PageMetadataContribution | PageMetadataContribution[] | null`
|
||||
|
||||
Contribution types:
|
||||
|
||||
- `{ kind: "meta", name: string, content: string, key?: string }` — `<meta name="..." content="...">`
|
||||
- `{ kind: "property", property: string, content: string, key?: string }` — `<meta property="..." content="...">` (OpenGraph)
|
||||
- `{ kind: "link", rel: "canonical" | "alternate", href: string, hreflang?: string, key?: string }` — `<link>` tag (HTTP/HTTPS URLs only)
|
||||
- `{ kind: "jsonld", id?: string, graph: object | object[] }` — `<script type="application/ld+json">`
|
||||
|
||||
Dedupe rules: first contribution wins per key. Canonical is singleton.
|
||||
|
||||
### `page:fragments` (Trusted Only)
|
||||
|
||||
Contributes raw HTML, scripts, or markup to `head`, `body:start`, or `body:end`. **Trusted plugins only.** Sandboxed plugins cannot register this hook — the manifest schema rejects it.
|
||||
|
||||
```typescript
|
||||
"page:fragments": async (event, ctx) => {
|
||||
return [
|
||||
{
|
||||
kind: "external-script",
|
||||
placement: "head",
|
||||
src: "https://www.googletagmanager.com/gtm.js?id=GTM-XXXXX",
|
||||
async: true,
|
||||
},
|
||||
{
|
||||
kind: "html",
|
||||
placement: "body:start",
|
||||
html: '<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-XXXXX" height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>',
|
||||
},
|
||||
];
|
||||
}
|
||||
```
|
||||
|
||||
Event: `{ page: PublicPageContext }`
|
||||
Returns: `PageFragmentContribution | PageFragmentContribution[] | null`
|
||||
|
||||
Contribution types:
|
||||
|
||||
- `{ kind: "external-script", placement, src, async?, defer?, attributes?, key? }`
|
||||
- `{ kind: "inline-script", placement, code, attributes?, key? }`
|
||||
- `{ kind: "html", placement, html, key? }`
|
||||
|
||||
Placements: `"head"`, `"body:start"`, `"body:end"`
|
||||
|
||||
## Execution Order
|
||||
|
||||
1. Lower `priority` values run first
|
||||
2. Equal priorities: plugin registration order
|
||||
3. `dependencies` array forces ordering regardless of priority
|
||||
|
||||
## Error Handling
|
||||
|
||||
- `errorPolicy: "abort"` (default) — pipeline stops, operation may fail
|
||||
- `errorPolicy: "continue"` — error logged, remaining hooks still run
|
||||
|
||||
Use `"continue"` for non-critical operations (analytics, notifications, external syncs).

# Portable Text Block Types
|
||||
|
||||
**Trusted plugins only.** PT blocks require Astro components for site-side rendering (`componentsEntry`), loaded at build time from an npm package. Sandboxed/marketplace plugins cannot define PT blocks.
|
||||
|
||||
Plugins can add custom block types to the Portable Text editor. These appear in the slash command menu and can be inserted into any `portableText` field.
|
||||
|
||||
## Declaring Block Types
|
||||
|
||||
In `definePlugin()`, declare blocks under `admin.portableTextBlocks`:
|
||||
|
||||
```typescript
|
||||
admin: {
|
||||
portableTextBlocks: [
|
||||
{
|
||||
type: "youtube",
|
||||
label: "YouTube Video",
|
||||
icon: "video",
|
||||
placeholder: "Paste YouTube URL...",
|
||||
fields: [
|
||||
{ type: "text_input", action_id: "id", label: "YouTube URL" },
|
||||
{ type: "text_input", action_id: "title", label: "Title" },
|
||||
{ type: "text_input", action_id: "poster", label: "Poster Image URL" },
|
||||
],
|
||||
},
|
||||
{
|
||||
type: "codepen",
|
||||
label: "CodePen",
|
||||
icon: "code",
|
||||
placeholder: "Paste CodePen URL...",
|
||||
},
|
||||
],
|
||||
}
|
||||
```
|
||||
|
||||
### Block Config Fields
|
||||
|
||||
| Field | Type | Description |
|
||||
| ------------- | -------- | ----------------------------------------------- |
|
||||
| `type` | `string` | Block type name (used in PT `_type`). Required. |
|
||||
| `label` | `string` | Display name in slash command menu. Required. |
|
||||
| `icon` | `string` | Icon key. Optional. |
|
||||
| `description` | `string` | Description in slash command menu. Optional. |
|
||||
| `placeholder` | `string` | Input placeholder text. Optional. |
|
||||
| `fields` | `array` | Block Kit form fields for editing UI. Optional. |
|
||||
|
||||
### Icons
|
||||
|
||||
Named icons: `video`, `code`, `link`, `link-external`. Unknown or missing falls back to a generic cube icon.
|
||||
|
||||
### Fields
|
||||
|
||||
When `fields` is declared, the editor renders a Block Kit form for editing. When omitted, a simple URL input is shown.
|
||||
|
||||
Fields use Block Kit element syntax:
|
||||
|
||||
```typescript
|
||||
fields: [
|
||||
{
|
||||
type: "text_input",
|
||||
action_id: "id",
|
||||
label: "URL",
|
||||
placeholder: "https://...",
|
||||
},
|
||||
{ type: "text_input", action_id: "title", label: "Title" },
|
||||
{ type: "text_input", action_id: "poster", label: "Poster Image" },
|
||||
{ type: "number_input", action_id: "start", label: "Start Time (seconds)" },
|
||||
{ type: "toggle", action_id: "autoplay", label: "Autoplay" },
|
||||
{
|
||||
type: "select",
|
||||
action_id: "size",
|
||||
label: "Size",
|
||||
options: [
|
||||
{ label: "Small", value: "small" },
|
||||
{ label: "Medium", value: "medium" },
|
||||
{ label: "Large", value: "large" },
|
||||
],
|
||||
},
|
||||
];
|
||||
```
|
||||
|
||||
See [Block Kit reference](./block-kit.md) for all element types.
|
||||
|
||||
The `action_id` of each field becomes a key in the Portable Text block data. The field with `action_id: "id"` is treated as the primary identifier (typically the URL).
|
||||
|
||||
### Data Flow
|
||||
|
||||
1. User types `/` in the editor and selects a block type
|
||||
2. Modal opens with Block Kit form (or simple URL input if no fields)
|
||||
3. User fills in fields and submits
|
||||
4. Block is inserted with `_type` set to the block type and field values as properties
|
||||
5. Editing an existing block re-opens the modal pre-populated
|
||||
|
||||
Portable Text output:
|
||||
|
||||
```json
|
||||
{
|
||||
"_type": "youtube",
|
||||
"_key": "abc123",
|
||||
"id": "https://youtube.com/watch?v=dQw4w9WgXcQ",
|
||||
"title": "Never Gonna Give You Up",
|
||||
"poster": "https://img.youtube.com/vi/dQw4w9WgXcQ/0.jpg"
|
||||
}
|
||||
```
|
||||
|
||||
## Site-Side Rendering
|
||||
|
||||
To render block types on the site, export Astro components from a `componentsEntry`.
|
||||
|
||||
### Component File
|
||||
|
||||
```typescript
|
||||
// src/astro/index.ts
|
||||
import YouTube from "./YouTube.astro";
|
||||
import CodePen from "./CodePen.astro";
|
||||
|
||||
// This export name is required
|
||||
export const blockComponents = {
|
||||
youtube: YouTube,
|
||||
codepen: CodePen,
|
||||
};
|
||||
```
|
||||
|
||||
### Astro Component
|
||||
|
||||
```astro
|
||||
---
|
||||
// src/astro/YouTube.astro
|
||||
const { id, title, poster } = Astro.props.node;
|
||||
|
||||
// Extract video ID from URL
|
||||
const videoId = id?.match(/(?:v=|youtu\.be\/)([^&]+)/)?.[1] ?? id;
|
||||
---
|
||||
|
||||
<div class="youtube-embed">
|
||||
<iframe
|
||||
src={`https://www.youtube-nocookie.com/embed/${videoId}`}
|
||||
title={title || "YouTube Video"}
|
||||
allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture"
|
||||
allowfullscreen
|
||||
></iframe>
|
||||
</div>
|
||||
```
|
||||
|
||||
Component receives `Astro.props.node` with the full block data.
|
||||
|
||||
### Plugin Descriptor
|
||||
|
||||
Set `componentsEntry` in the descriptor:
|
||||
|
||||
```typescript
|
||||
export function myPlugin(options = {}): PluginDescriptor {
|
||||
return {
|
||||
id: "my-plugin",
|
||||
entrypoint: "@my-org/my-plugin",
|
||||
componentsEntry: "@my-org/my-plugin/astro",
|
||||
version: "1.0.0",
|
||||
options,
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
### Package Exports
|
||||
|
||||
Add the `./astro` export:
|
||||
|
||||
```json
|
||||
{
|
||||
"exports": {
|
||||
".": { "types": "./dist/index.d.ts", "import": "./dist/index.js" },
|
||||
"./admin": { "types": "./dist/admin.d.ts", "import": "./dist/admin.js" },
|
||||
"./astro": {
|
||||
"types": "./dist/astro/index.d.ts",
|
||||
"import": "./dist/astro/index.js"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Auto-Wiring
|
||||
|
||||
Plugin block components are automatically merged into `<PortableText>` on the site. Merge order:
|
||||
|
||||
1. EmDash defaults (lowest priority)
|
||||
2. Plugin block components
|
||||
3. User-provided components (highest priority)
|
||||
|
||||
Site authors don't need to import anything. User components take precedence over plugin defaults.
|
||||
|
||||
## Complete Example
|
||||
|
||||
```typescript
|
||||
// src/index.ts
|
||||
import { definePlugin } from "emdash";
|
||||
import type { PluginDescriptor } from "emdash";
|
||||
|
||||
export function embedsPlugin(options = {}): PluginDescriptor {

# Publishing to the Marketplace
|
||||
|
||||
Sandboxed plugins can be published to the EmDash Marketplace for one-click installation from the admin UI.
|
||||
|
||||
## Bundle Format
|
||||
|
||||
Published plugins are `.tar.gz` tarballs:
|
||||
|
||||

| `manifest.json` | Yes | Metadata extracted from `definePlugin()` |
|
||||
| `backend.js` | No | Bundled sandbox code (self-contained ES module) |

||||
| `README.md` | No | Plugin documentation |

|
||||
## Package Exports for Bundling
|
||||
|
||||
The bundle command uses `package.json` exports to find entrypoints:
|
||||
|
||||
```json
|
||||
{
|
||||
"exports": {
|
||||
".": { "import": "./dist/index.mjs" },
|
||||
"./sandbox": { "import": "./dist/sandbox-entry.mjs" },
|
||||
"./admin": { "import": "./dist/admin.mjs" }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
| Export | Purpose | Built as |
|
||||
| ------------- | ----------------------------- | ------------------------------------ |
|
||||
| `"."` | Main entry — extract manifest | Externals: `emdash`, `@emdash-cms/*` |
|
||||
| `"./sandbox"` | Backend code for the sandbox | Fully self-contained (no externals) |
|
||||
| `"./admin"` | Admin UI components | Fully self-contained |
|
||||
|
||||
If `"./sandbox"` is missing, the command looks for `src/sandbox-entry.ts`.
|
||||
|
||||
## Build and Publish
|
||||
|
||||
```bash
|
||||
# Bundle only (inspect first)
|
||||
emdash plugin bundle
|
||||
tar tzf dist/my-plugin-1.0.0.tar.gz
|
||||
|
||||
# Publish (uploads to marketplace)
|
||||
emdash plugin publish
|
||||
|
||||
# Build + publish in one step
|
||||
emdash plugin publish --build
|
||||
```
|
||||
|
||||
First-time publish authenticates via GitHub device authorization. Token stored in `~/.config/emdash/auth.json` (30-day expiry).
|
||||
|
||||
## Validation
|
||||
|
||||
The bundle command checks:
|
||||
|
||||
- **Size limit** — Total bundle under 5MB
|
||||
- **No Node.js built-ins** — `backend.js` cannot import `fs`, `path`, etc.
|
||||
- **Sandbox-incompatible features** — Warns if the plugin declares `portableTextBlocks`, `admin.entry` (React components), or API `routes`, since these require trusted mode
|
||||
- **Icon dimensions** — 256x256 PNG (warns if wrong)
|
||||
- **Screenshot limits** — Max 5, max 1920x1080
|
||||
|
||||
## Security Audit
|
||||
|
||||
Every published version is automatically audited for:
|
||||
|
||||
- Data exfiltration patterns
|
||||
- Credential harvesting via settings
|
||||
- Obfuscated code
|
||||
- Resource abuse (crypto mining, etc.)
|
||||
- Suspicious network activity
|
||||
|
||||
Verdict: **pass**, **warn**, or **fail** — displayed on marketplace listing.
|
||||
|
||||
## Version Requirements
|
||||
|
||||
- Each version must have higher semver than the last
|
||||
- Cannot overwrite or republish an existing version
|
||||
- Plugin ID is auto-registered on first publish

# Storage, KV & Settings
|
||||
|
||||
Plugins have three data mechanisms:
|
||||
|
||||
| Mechanism | Purpose | Access |
|
||||
| ------------------- | ----------------------------------------- | ---------------------- |
|
||||
| **Storage** | Document collections with indexed queries | `ctx.storage` |
|
||||
| **KV** | Key-value pairs for state and settings | `ctx.kv` |
|
||||
| **Settings Schema** | Auto-generated admin UI for configuration | `admin.settingsSchema` |
|
||||
|
||||
## Storage Collections
|
||||
|
||||
Declare in `definePlugin({ storage })`. EmDash creates the schema automatically — no migrations.
|
||||
|
||||
```typescript
|
||||
definePlugin({
|
||||
id: "forms",
|
||||
version: "1.0.0",
|
||||
|
||||
storage: {
|
||||
submissions: {
|
||||
indexes: [
|
||||
"formId", // Single-field index
|
||||
"status",
|
||||
"createdAt",
|
||||
["formId", "createdAt"], // Composite index
|
||||
],
|
||||
},
|
||||
forms: {
|
||||
indexes: ["slug"],
|
||||
},
|
||||
},
|
||||
});
|
||||
```
|
||||
|
||||
Storage is scoped to the plugin — `submissions` in plugin `forms` is separate from `submissions` in another plugin.
|
||||
|
||||
### CRUD
|
||||
|
||||
```typescript
|
||||
const { submissions } = ctx.storage;
|
||||
|
||||
await submissions.put("sub_123", { formId: "contact", email: "user@example.com" });
|
||||
const item = await submissions.get("sub_123");
|
||||
const exists = await submissions.exists("sub_123");
|
||||
await submissions.delete("sub_123");
|
||||
```
|
||||
|
||||
### Batch Operations
|
||||
|
||||
```typescript
|
||||
const items = await submissions.getMany(["sub_1", "sub_2"]); // Map<string, T>
|
||||
|
||||
await submissions.putMany([
|
||||
{ id: "sub_1", data: { formId: "contact", status: "new" } },
|
||||
{ id: "sub_2", data: { formId: "contact", status: "new" } },
|
||||
]);
|
||||
|
||||
const deletedCount = await submissions.deleteMany(["sub_1", "sub_2"]);
|
||||
```
|
||||
|
||||
### Querying
|
||||
|
||||
Only indexed fields can be queried. Non-indexed queries throw.
|
||||
|
||||
```typescript
|
||||
const result = await ctx.storage.submissions.query({
|
||||
where: {
|
||||
formId: "contact",
|
||||
status: "pending",
|
||||
},
|
||||
orderBy: { createdAt: "desc" },
|
||||
limit: 20,
|
||||
});
|
||||
|
||||
// result.items - Array of { id, data }
|
||||
// result.cursor - Pagination cursor
|
||||
// result.hasMore - Boolean
|
||||
```
|
||||
|
||||
### Where Operators
|
||||
|
||||
```typescript
|
||||
// Exact match
|
||||
where: { status: "pending" }
|
||||
|
||||
// Range
|
||||
where: { createdAt: { gte: "2024-01-01" } }
|
||||
where: { score: { gt: 50, lte: 100 } }
|
||||
|
||||
// In
|
||||
where: { status: { in: ["pending", "approved"] } }
|
||||
|
||||
// Starts with
|
||||
where: { slug: { startsWith: "blog-" } }
|
||||
```
|
||||
|
||||
### Pagination
|
||||
|
||||
```typescript
|
||||
let cursor: string | undefined;
|
||||
do {
|
||||
const result = await ctx.storage.submissions!.query({
|
||||
orderBy: { createdAt: "desc" },
|
||||
limit: 100,
|
||||
cursor,
|
||||
});
|
||||
// process result.items
|
||||
cursor = result.cursor;
|
||||
} while (cursor);
|
||||
```
|
||||
|
||||
### Counting
|
||||
|
||||
```typescript
|
||||
const total = await ctx.storage.submissions!.count();
|
||||
const pending = await ctx.storage.submissions!.count({ status: "pending" });
|
||||
```
|
||||
|
||||
### Index Design
|
||||
|
||||
| Query Pattern | Index Needed |
|
||||
| ---------------------------------------- | ------------------------- |
|
||||
| Filter by `formId` | `"formId"` |
|
||||
| Filter by `formId`, order by `createdAt` | `["formId", "createdAt"]` |
|
||||
| Order by `createdAt` only | `"createdAt"` |
|
||||
|
||||
Composite indexes support filtering on the first field + ordering by the second.
|
||||
|
||||
### Type Safety
|
||||
|
||||
```typescript
|
||||
interface Submission {
|
||||
formId: string;
|
||||
status: "pending" | "approved" | "spam";
|
||||
createdAt: string;
|
||||
}
|
||||
|
||||
// Cast in hook/route handlers
|
||||
const submissions = ctx.storage.submissions as StorageCollection<Submission>;
|
||||
```
|
||||
|
||||
### Full API
|
||||
|
||||
```typescript
|
||||
interface StorageCollection<T = unknown> {
|
||||
get(id: string): Promise<T | null>;
|
||||
put(id: string, data: T): Promise<void>;
|
||||
delete(id: string): Promise<boolean>;
|
||||
exists(id: string): Promise<boolean>;
|
||||
getMany(ids: string[]): Promise<Map<string, T>>;
|
||||
putMany(items: Array<{ id: string; data: T }>): Promise<void>;
|
||||
deleteMany(ids: string[]): Promise<number>;
|
||||
query(options?: QueryOptions): Promise<PaginatedResult<{ id: string; data: T }>>;
|
||||
count(where?: WhereClause): Promise<number>;
|
||||
}
|
||||
```
|
||||
|
||||
## KV Store
|
||||
|
||||
General-purpose key-value store. Use for internal state, cached computations, or programmatic access to settings.
|
||||
|
||||
```typescript
|
||||
interface KVAccess {
|
||||
get<T>(key: string): Promise<T | null>;
|
||||
set(key: string, value: unknown): Promise<void>;
|
||||
delete(key: string): Promise<boolean>;
|
||||
list(prefix?: string): Promise<Array<{ key: string; value: unknown }>>;
|
||||
}
|
||||
```
|
||||
|
||||
### Key Naming Conventions
|
||||
|
||||
| Prefix | Purpose | Example |
|
||||
| ----------- | ----------------------------- | ----------------- |
|
||||
| `settings:` | User-configurable preferences | `settings:apiKey` |
|
||||
| `state:` | Internal plugin state | `state:lastSync` |
|
||||
| `cache:` | Cached data | `cache:results` |
|
||||
|
||||
```typescript
|
||||
await ctx.kv.set("settings:webhookUrl", url);
|
||||
await ctx.kv.set("state:lastRun", new Date().toISOString());
|
||||
const allSettings = await ctx.kv.list("settings:");
|
||||
```
|
||||
|
||||
## Settings Schema
|
||||
|
||||
Declare `admin.settingsSchema` to auto-generate a settings form in the admin UI:
|
||||
|
||||
```typescript
|
||||
admin: {
|
||||
settingsSchema: {
|
||||
siteTitle: {
|
||||
type: "string",
|
||||
label: "Site Title",
|
||||
description: "Used in title tags",
|
||||
default: "",
|
||||
},
|
||||
maxItems: {
|
||||
type: "number",
|
||||
label: "Max Items",
|
||||
default: 100,
|
||||
min: 1,
|
||||
max: 1000,
|
||||
},
|
||||
enabled: {
|
||||
type: "boolean",
|
||||
label: "Enabled",
|
||||
default: true,
|
||||
},
|
||||
theme: {
|
||||
type: "select",
|
||||
label: "Theme",
|
||||
options: [
|
||||
{ value: "light", label: "Light" },
|
||||
{ value: "dark", label: "Dark" },
|
||||
],
|
||||
default: "light",
|
||||
},
|
||||
apiKey: {
|
||||
type: "secret",
|
||||
label: "API Key",
|
||||
description: "Encrypted at rest",
|
||||
},
|
||||
},
|
||||
}
|
||||
```
|
||||
|
||||
### Setting Types
|
||||
|
||||
| Type | UI | Notes |
|
||||
| --------- | ------------ | ----------------------------------------- |
|
||||
| `string` | Text input | Optional `multiline: true` for textarea |
|
||||
| `number` | Number input | Optional `min`, `max` |
|
||||
| `boolean` | Toggle | |
|
||||
| `select` | Dropdown | Requires `options: [{ value, label }]` |
|
||||
| `secret` | Masked input | Encrypted at rest, never shown after save |
|
||||
|
||||
### Reading Settings
|
||||
|
||||
Settings are accessed via KV with `settings:` prefix:
|
||||
|
||||
```typescript
|
||||
const enabled = (await ctx.kv.get<boolean>("settings:enabled")) ?? true;
|
||||
const apiKey = await ctx.kv.get<string>("settings:apiKey");
|
||||
```
|
||||
|
||||
Schema defaults are UI defaults only — not auto-persisted. Handle missing values with `??` or persist defaults in `plugin:install`:
|
||||
|
||||
```typescript
|
||||
"plugin:install": async (_event, ctx) => {
|
||||
await ctx.kv.set("settings:enabled", true);
|
||||
await ctx.kv.set("settings:maxItems", 100);
|
||||
}
|
||||
```
|
||||
|
||||
## When to Use What
|
||||
|
||||
| Use Case | Mechanism |
|
||||
| -------------------------------------------- | --------------------------------- |
|
||||
| Admin-editable preferences | `settingsSchema` + KV `settings:` |
|
||||
| Internal state (timestamps, cursors) | KV `state:` |
|
||||
| Collections of documents (logs, submissions) | Storage |
|
||||
| Cached computations | KV `cache:` |

# Editing Flow
|
||||
|
||||
How content editing works through the CLI. Covers Portable Text conversion, `_rev` tokens, and raw mode.
|
||||
|
||||
## Portable Text and Markdown
|
||||
|
||||
EmDash stores rich text as [Portable Text](https://portabletext.org/) (PT) — a structured JSON format. The CLI automatically converts between PT and markdown so you work with a familiar text format.
|
||||
|
||||
### Automatic Conversion
|
||||
|
||||
- **On read**: PT arrays in `portableText` fields are converted to markdown strings
|
||||
- **On write**: markdown strings in `portableText` fields are converted back to PT arrays
|
||||
- **Non-PT fields** (string, text, number, etc.) pass through unchanged
|
||||
|
||||
The CLI detects which fields need conversion by fetching the collection's field schema.
|
||||
|
||||
### Supported Markdown Syntax
|
||||
|
||||
Standard blocks (lossless round-trip):
|
||||
|
||||
| Markdown | PT block |
|
||||
| ---------------------------- | ------------------------------------------ |
|
||||
| `# Heading` through `######` | h1-h6 blocks |
|
||||
| Plain paragraph | normal block |
|
||||
| `> Quote` | blockquote |
|
||||
| `- item` / `* item` | bullet list (nesting via 2-space indent) |
|
||||
| `1. item` | numbered list (nesting via 2-space indent) |
|
||||
| ` ``` ```lang``` ` | code block with language |
|
||||
| `` | image block |
|
||||
|
||||
Inline marks:
|
||||
|
||||
| Markdown | PT mark |
|
||||
| ------------- | --------------- |
|
||||
| `**bold**` | `strong` |
|
||||
| `_italic_` | `em` |
|
||||
| `` `code` `` | `code` |
|
||||
| `~~strike~~` | `strikethrough` |
|
||||
| `[text](url)` | link annotation |
|
||||
|
||||
### Unknown Blocks (Opaque Fences)
|
||||
|
||||
Blocks the converter doesn't recognize (custom blocks, embeds, etc.) are serialized as HTML comments:
|
||||
|
||||
```markdown
|
||||
<!--ec:block {"_type":"callout","level":"warning","text":"Be careful"} -->
|
||||
```
|
||||
|
||||
These survive round-trips intact. You can see and move them, but editing the JSON risks corruption. On write, they're deserialized back to the original PT block.
|
||||
|
||||
### Raw Mode
|
||||
|
||||
Skip markdown conversion entirely to work with raw PT JSON:
|
||||
|
||||
```bash
|
||||
npx emdash content get posts 01ABC123 --raw
|
||||
```
|
||||
|
||||
Use raw mode when:
|
||||
|
||||
- You need exact control over PT structure
|
||||
- You're working with custom block types
|
||||
- You're copying PT between items without transformation
|
||||
|
||||
### Writing Content
|
||||
|
||||
When creating or updating content, each field is checked:
|
||||
|
||||
- `portableText` field + **string value** → converts markdown to PT before sending
|
||||
- `portableText` field + **array value** → sends as raw PT (no conversion)
|
||||
- Any other field type → sends as-is
|
||||
|
||||
```bash
|
||||
# Markdown string — converted to PT automatically
|
||||
npx emdash content create posts --data '{"title": "Hello", "body": "# Welcome\n\nThis is **bold**."}'
|
||||
|
||||
# Raw PT array — passed through as-is
|
||||
npx emdash content create posts --data '{"title": "Hello", "body": [{"_type": "block", "children": [{"_type": "span", "text": "Welcome"}]}]}'
|
||||
```
|
||||
|
||||
## Auto-Publishing
|
||||
|
||||
The CLI is designed for agents. It auto-publishes on `create` and `update` by default so agents get read-after-write consistency without managing the draft/publish lifecycle.
|
||||
|
||||
### How It Works
|
||||
|
||||
- **`create`** — creates the item, then publishes it. The returned item is in `published` status.
|
||||
- **`update`** — updates the item. If the collection uses revisions and the update created a draft revision, it auto-publishes to promote the draft to the content table. The returned item reflects the updated data.
|
||||
- **`get`** — returns the latest state. If a pending draft exists (e.g. someone edited in the admin UI but didn't publish), the draft data is returned instead of the published data. Use `--published` to see only published data.
|
||||
|
||||
Use `--draft` on create/update to skip auto-publishing.
|
||||
|
||||
### Why Auto-Publish?
|
||||
|
||||
EmDash collections can support draft revisions. When they do, `update` writes data to a draft revision instead of the content table. Without auto-publish, an agent would update, then `get` the item, and see stale published data — not the changes it just made. Auto-publish eliminates this confusion.
|
||||
|
||||
## Read-Before-Write
|
||||
|
||||
Updates use `_rev` tokens for optimistic concurrency — the same principle as a file editing tool that requires you to read a file before you can edit it. You must see what you're overwriting.
|
||||
|
||||
### The Analogy
|
||||
|
||||
Think of it like a filesystem edit tool:
|
||||
|
||||
1. You **read** the file to see its current contents
|
||||
2. You decide what to change
|
||||
3. You **write** with a reference to the version you read
|
||||
|
||||
If someone else changed the file between your read and your write, the write fails — you can't overwrite changes you haven't seen. The `_rev` token is your proof that you've seen the current state.
|
||||
|
||||
### How It Works
|
||||
|
||||
1. `content get` returns the item with a `_rev` token in the output
|
||||
2. You pass that `_rev` back to `content update` via `--rev`
|
||||
3. The server checks: if the item has changed since your read, it returns **409 Conflict**
|
||||
4. A successful update returns a new `_rev` for subsequent edits
|
||||
|
||||
### What Is a `_rev` Token?
|
||||
|
||||
An opaque base64 string. Don't parse it — just pass it back.
|
||||
|
||||
### CLI Workflow
|
||||
|
||||
The CLI **requires** `--rev` on updates. The typical workflow:
|
||||
|
||||
```bash
|
||||
# 1. Read the item — note the _rev in the output
|
||||
npx emdash content get posts 01ABC123
|
||||
# Output includes: _rev: MToyMDI2LTAyLTE0...
|
||||
|
||||
# 2. Update with the _rev you received — auto-publishes by default
|
||||
npx emdash content update posts 01ABC123 \
|
||||
--rev MToyMDI2LTAyLTE0... \
|
||||
--data '{"title": "New Title"}'
|
||||
# Output shows updated item with new _rev
|
||||
```
|
||||
|
||||
If you try to update without `--rev`, the CLI rejects the command. This ensures you always know what you're overwriting.
|
||||
|
||||
### Conflict Handling
|
||||
|
||||
If someone else updated the item between your read and write:
|
||||
|
||||
```
|
||||
EmDashApiError: Content has been modified since last read (version conflict)
|
||||
status: 409
|
||||
code: CONFLICT
|
||||
```
|
||||
|
||||
Resolution: re-read with `get`, inspect the new state, then `update` with the fresh `_rev`.
|
||||
|
||||
### Which Operations Need `_rev`?
|
||||
|
||||
Only `update`. All other operations are either idempotent or non-destructive:
|
||||
|
||||
| Command | `--rev` needed? | Why |
|
||||
| ------------------- | --------------- | ------------------------ |
|
||||
| `content create` | No | Nothing exists yet |
|
||||
| `content update` | **Yes** | Overwrites existing data |
|
||||
| `content delete` | No | Soft delete, reversible |
|
||||
| `content publish` | No | Idempotent status change |
|
||||
| `content unpublish` | No | Idempotent status change |
|
||||
| `content schedule` | No | Only changes metadata |
|
||||
| `content restore` | No | Restores from trash |

# EmDash CLI
|
||||
|
||||
The EmDash CLI (`emdash` or `ec`) manages EmDash CMS instances. Commands fall into two categories:
|
||||
|
||||
- **Local commands** — work directly on a SQLite file, no running server needed: `init`, `dev`, `seed`, `export-seed`, `auth secret`
|
||||
- **Remote commands** — talk to a running EmDash instance via HTTP: `types`, `login`, `logout`, `whoami`, `content`, `schema`, `media`, `search`, `taxonomy`, `menu`
|
||||
|
||||
## Authentication
|
||||
|
||||
Remote commands resolve auth automatically:
|
||||
|
||||
1. `--token` flag
|
||||
2. `EMDASH_TOKEN` env var
|
||||
3. Stored credentials from `emdash login`
|
||||
4. Dev bypass (localhost only — no token needed)
|
||||
|
||||
For local dev servers, just run the command — auth is handled automatically. For remote instances, run `emdash login --url https://my-site.pages.dev` first.
|
||||
|
||||
## Custom Headers & Reverse Proxies
|
||||
|
||||
Sites behind Cloudflare Access or other reverse proxies need auth headers on every request. The CLI supports this via `--header` flags and environment variables.
|
||||
|
||||
### Service Tokens (Recommended for CI/Automation)
|
||||
|
||||
```bash
|
||||
# Single header
|
||||
npx emdash login --url https://my-site.pages.dev \
|
||||
--header "CF-Access-Client-Id: xxx.access" \
|
||||
--header "CF-Access-Client-Secret: yyy"
|
||||
|
||||
# Short form
|
||||
npx emdash login -H "CF-Access-Client-Id: xxx" -H "CF-Access-Client-Secret: yyy"
|
||||
|
||||
# Via environment (newline-separated)
|
||||
export EMDASH_HEADERS="CF-Access-Client-Id: xxx
|
||||
CF-Access-Client-Secret: yyy"
|
||||
npx emdash login --url https://my-site.pages.dev
|
||||
```
|
||||
|
||||
Headers are persisted to `~/.config/emdash/auth.json` after login, so subsequent commands inherit them automatically.
|
||||
|
||||
### Cloudflare Access Browser Flow
|
||||
|
||||
If you don't have service tokens and `cloudflared` is installed, the CLI will automatically:
|
||||
|
||||
1. Detect when Access blocks the request
|
||||
2. Try to get a cached JWT via `cloudflared access token`
|
||||
3. Fall back to `cloudflared access login` for browser-based auth
|
||||
|
||||
This works for interactive use but isn't suitable for CI. Use service tokens for automation.
|
||||
|
||||
### Generic Reverse Proxy Auth
|
||||
|
||||
The `--header` flag works with any auth scheme:
|
||||
|
||||
```bash
|
||||
# Basic auth
|
||||
npx emdash login --url https://example.com -H "Authorization: Basic dXNlcjpwYXNz"
|
||||
|
||||
# Custom auth header
|
||||
npx emdash login --url https://example.com -H "X-API-Key: secret123"
|
||||
```
|
||||
|
||||
## Quick Reference
|
||||
|
||||
### Database Setup
|
||||
|
||||
```bash
|
||||
# Initialize database with migrations
|
||||
npx emdash init
|
||||
|
||||
# Start dev server (runs migrations, starts Astro)
|
||||
npx emdash dev
|
||||
|
||||
# Start dev server and generate types from remote
|
||||
npx emdash dev --types
|
||||
|
||||
# Apply a seed file
|
||||
npx emdash seed .emdash/seed.json
|
||||
|
||||
# Export database as seed
|
||||
npx emdash export-seed > seed.json
|
||||
npx emdash export-seed --with-content > seed.json
|
||||
```
|
||||
|
||||
### Type Generation
|
||||
|
||||
```bash
|
||||
# Generate types from local dev server
|
||||
npx emdash types
|
||||
|
||||
# Generate from remote
|
||||
npx emdash types --url https://my-site.pages.dev
|
||||
|
||||
# Custom output path
|
||||
npx emdash types --output src/types/cms.ts
|
||||
```
|
||||
|
||||
Writes `.emdash/types.ts` (TypeScript interfaces) and `.emdash/schema.json`.
|
||||
|
||||
### Authentication
|
||||
|
||||
```bash
|
||||
# Login (OAuth Device Flow)
|
||||
npx emdash login --url https://my-site.pages.dev
|
||||
|
||||
# Check current user
|
||||
npx emdash whoami
|
||||
|
||||
# Logout
|
||||
npx emdash logout
|
||||
|
||||
# Generate auth secret for deployment
|
||||
npx emdash auth secret
|
||||
```
|
||||
|
||||
### Content CRUD
|
||||
|
||||
The CLI is designed for agents. Create and update auto-publish by default so agents get read-after-write consistency without managing drafts.
|
||||
|
||||
```bash
|
||||
# List content
|
||||
npx emdash content list posts
|
||||
npx emdash content list posts --status published --limit 10
|
||||
|
||||
# Get a single item (Portable Text fields converted to markdown)
|
||||
# Returns draft data if a pending draft exists
|
||||
npx emdash content get posts 01ABC123
|
||||
npx emdash content get posts 01ABC123 --raw # skip PT->markdown conversion
|
||||
npx emdash content get posts 01ABC123 --published # ignore pending drafts
|
||||
|
||||
# Create content (auto-publishes by default)
|
||||
npx emdash content create posts --data '{"title": "Hello", "body": "# World"}'
|
||||
npx emdash content create posts --file post.json --slug hello-world
|
||||
npx emdash content create posts --draft --data '...' # keep as draft
|
||||
cat post.json | npx emdash content create posts --stdin
|
||||
|
||||
# Update (requires --rev from a prior get, auto-publishes by default)
|
||||
npx emdash content update posts 01ABC123 --rev MToyMDI2... --data '{"title": "Updated"}'
|
||||
npx emdash content update posts 01ABC123 --rev MToyMDI2... --draft --data '...' # keep as draft
|
||||
|
||||
# Delete (soft delete)
|
||||
npx emdash content delete posts 01ABC123
|
||||
|
||||
# Lifecycle
|
||||
npx emdash content publish posts 01ABC123
|
||||
npx emdash content unpublish posts 01ABC123
|
||||
npx emdash content schedule posts 01ABC123 --at 2026-03-01T09:00:00Z
|
||||
npx emdash content restore posts 01ABC123
|
||||
```
|
||||
|
||||
### Schema Management
|
||||
|
||||
```bash
|
||||
# List collections
|
||||
npx emdash schema list
|
||||
|
||||
# Get collection with fields
|
||||
npx emdash schema get posts
|
||||
|
||||
# Create collection
|
||||
npx emdash schema create articles --label Articles --description "Blog articles"
|
||||
|
||||
# Delete collection
|
||||
npx emdash schema delete articles --force
|
||||
|
||||
# Add field
|
||||
npx emdash schema add-field posts body --type portableText --label "Body Content"
|
||||
npx emdash schema add-field posts featured --type boolean --required
|
||||
|
||||
# Remove field
|
||||
npx emdash schema remove-field posts featured
|
||||
```
|
||||
|
||||
Field types: `string`, `text`, `number`, `integer`, `boolean`, `datetime`, `image`, `reference`, `portableText`, `json`.
|
||||
|
||||
### Media
|
||||
|
||||
```bash
|
||||
# List media
|
||||
npx emdash media list
|
||||
npx emdash media list --mime image/png
|
||||
|
||||
# Upload
|
||||
npx emdash media upload ./photo.jpg --alt "A sunset" --caption "Bristol, 2026"
|
||||
|
||||
# Get / delete
|
||||
npx emdash media get 01MEDIA123
|
||||
npx emdash media delete 01MEDIA123
|
||||
```
|
||||
|
||||
### Search
|
||||
|
||||
```bash
|
||||
npx emdash search "hello world"
|
||||
npx emdash search "hello" --collection posts --limit 5
|
||||
```
|
||||
|
||||
### Taxonomies
|
||||
|
||||
```bash
|
||||
npx emdash taxonomy list
|
||||
npx emdash taxonomy terms categories
|
||||
npx emdash taxonomy add-term categories --name "Tech" --slug tech
|
||||
npx emdash taxonomy add-term categories --name "Frontend" --parent 01PARENT123
|
||||
```
|
||||
|
||||
### Menus
|
||||
|
||||
```bash
|
||||
npx emdash menu list
|
||||
npx emdash menu get primary
|
||||
```
|
||||
|
||||
## Drafts and Publishing
|
||||
|
||||
The CLI auto-publishes on `create` and `update` by default. This means:
|
||||
|
||||
- **`create`** creates the item and immediately publishes it
|
||||
- **`update`** updates the item and publishes if a draft revision was created
|
||||
- **`get`** returns draft data if a pending draft exists (e.g. from the admin UI)
|
||||
|
||||
Use `--draft` on create/update to skip auto-publishing. Use `--published` on get to ignore pending drafts.
|
||||
|
||||
Collections that support revisions store edits as draft revisions. The CLI handles this transparently — agents don't need to know whether a collection uses revisions or not.
|
||||
|
||||
## JSON Output
|
||||
|
||||
All remote commands support `--json` for machine-readable output. It's auto-enabled when stdout is piped.
|
||||
|
||||
```bash
|
||||
# Pipe to jq
|
||||
npx emdash content list posts --json | jq '.items[].slug'
|
||||
|
||||
# Use in scripts
|
||||
ID=$(npx emdash content create posts --data '{"title":"Hello"}' --json | jq -r '.id')
|
||||
```
|
||||
|
||||
## Editing Flow
|
||||
|
||||
