# Contributing

Dyad is still a very early-stage project, thus the codebase is rapidly changing.

Before opening a pull request, please open an issue and discuss whether the change makes sense in Dyad. Ensuring a cohesive user experience sometimes means we can't include every possible feature or we need to consider the long-term design of how we want to support a feature area.

For a high-level overview of how Dyad works, please see the [Architecture Guide](./docs/architecture.md). Understanding the architecture will help ensure your contributions align with the overall design of the project.

## More than code contributions

Something that I really appreciate are all the non-code contributions, such as reporting bugs, writing feature requests and participating on [Dyad's sub-reddit](https://www.reddit.com/r/dyadbuilders).

## Development

Dyad is an Electron app.

**Install dependencies:**

```sh
npm install
```

**Create the userData directory (required for database)**

```sh
# Unix/macOS/Linux:
mkdir -p userData

# Windows PowerShell (run only if folder doesn't exist):
mkdir userData

# Windows Command Prompt (run only if folder doesn't exist):
md userData
```

**Apply migrations:**

```sh
# Generate and apply database migrations
npm run db:generate
npm run db:push
```

**Run locally:**

```sh
npm start
```

## Setup

If you'd like to contribute a pull request, we highly recommend setting the pre-commit hooks which will run the formatter and linter before each git commit. This is a great way of catching issues early on without waiting to run the GitHub Actions for your pull requet.

Simply run this once in your repo:

```sh
npm run init-precommit
```

## Testing

### Unit tests

```sh
npm test
```

### E2E tests

Build the app for E2E testing:

```sh
npm run pre:e2e
```

> Note: you only need to re-build the app when changing the app code. You don't need to re-build the app if you're just updating the tests.

Run the whole e2e test suite:

```sh
npm run e2e
```

Run a specific test file:

```sh
npm run e2e e2e-tests/context_manage.spec.ts
```

Update snapshots for a test:

```sh
npm run e2e e2e-tests/context_manage.spec.ts -- --update-snapshots
```
