# Contributing
## Setup
```bash
git clone https://github.com/YOUR_USERNAME/next-ai-draw-io.git
cd next-ai-draw-io
npm install
cp env.example .env.local
npm run dev
```
## Code Style
We use [Biome](https://biomejs.dev/) for linting and formatting:
```bash
npm run format # Format code
npm run lint # Check lint errors
npm run check # Run all checks (CI)
```
Git hooks via Husky run automatically:
- **Pre-commit**: Biome (format/lint) + TypeScript type check
- **Pre-push**: Unit tests
For a better experience, install the [Biome VS Code extension](https://marketplace.visualstudio.com/items?itemName=biomejs.biome) for real-time linting and format-on-save.
## Testing
Run tests before submitting PRs:
```bash
npm run test # Unit tests (Vitest)
npm run test:e2e # E2E tests (Playwright)
```
E2E tests use mocked API responses - no AI provider needed. Tests are in `tests/e2e/`.
To run a specific test file:
```bash
npx playwright test tests/e2e/diagram-generation.spec.ts
```
To run tests with UI mode:
```bash
npx playwright test --ui
```
## Pull Requests
1. Create a feature branch
2. Make changes (pre-commit runs lint + type check automatically)
3. Run E2E tests with `npm run test:e2e`
4. Push (pre-push runs unit tests automatically)
5. Submit PR against `main` with a clear description
CI will run the full test suite on your PR.
## Issues
Include steps to reproduce, expected vs actual behavior, and AI provider used.
