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:

File	Required	Description
`manifest.json`	Yes	Metadata extracted from `definePlugin()`
`backend.js`	No	Bundled sandbox code (self-contained ES module)
`admin.js`	No	Bundled admin UI code
`README.md`	No	Plugin documentation
`icon.png`	No	Plugin icon (256x256 PNG)
`screenshots/`	No	Up to 5 screenshots (PNG/JPEG, max 1920x1080)

Package Exports for Bundling

The bundle command uses package.json exports to find entrypoints:

{
	"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

# 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
