Copy the environment file: + + ```bash + # Unix/Linux/Mac + cp apps/web/.env.example apps/web/.env.local + + # Windows PowerShell + Copy-Item apps/web/.env.example apps/web/.env.local + ``` + +3.

Install dependencies and start the dev server: + + ```bash + bun install + bun dev:web + ``` + +The application will be available at [http://localhost:3000](http://localhost:3000). + +The `.env.example` has sensible defaults that match the Docker Compose config — it should work out of the box. + +### Desktop setup + +Desktop is opt-in.

Build the package once from the repo root: + + ```bash + bun run build:wasm + ``` + +2. Register the generated package for linking: + + ```bash + cd rust/wasm/pkg + bun link + ``` + +3. Link `apps/web` to the local package: + + ```bash + cd apps/web + bun link opencut-wasm + ``` + +4. Rebuild on changes while you work: + + ```bash + bun dev:wasm + ``` + +To switch `apps/web` back to the published package, run: + +```bash +cd apps/web +bun add opencut-wasm +``` + +### Self-Hosting with Docker + +To run everything (including a production build of the app) in Docker: + +```bash +docker compose up -d +``` + +The app will be available at [http://localhost:3100](http://localhost:3100). + +## Contributing + +We welcome contributions!
