# open http://0.0.0.0:3000 in browser

Requirements

• Docker
• Make
• Node.js >= 20 (для локальной разработки без Docker)

You may pass environment variable SERVER_MESSAGE, and its value shows on the main page.

Getting Bugsink DSN

Bugsink runs as a local service via Docker Compose. To get the DSN:

1. Start the services: make compose
2. Open http://localhost:8000 and log in (admin@example.com / admin)
3. Create a new project
4. Copy the DSN from the project settings — it looks like: http://<key>@bugsink:8000/<project_id>
5. Add it to your .env file:

   SENTRY_DSN=http://<key>@bugsink:8000/<project_id>

6. Restart the app: docker compose restart app
