Supabase Local Development

To set up a local Supabase environment, use the Supabase CLI to initialize your project and boot local services like Postgres and Auth in Docker containers. This enables complete offline development without network latency.

Yes, you can safely test database migrations locally before production. Running the full Supabase stack in Docker containers provides an isolated environment to validate schema changes and ensure migration integrity without affecting live data.

Local Supabase type generation automatically creates TypeScript definitions from your local Postgres schema. By using the Supabase CLI, you generate accurate types directly from your offline database, ensuring type safety during development.

Yes, Docker and the Supabase CLI are required to run local Supabase services. The CLI manages project initialization and startup, while Docker hosts the complete local stack including Postgres, Auth, Storage, Edge Functions, and Realtime components.

When running Supabase locally, environment variable management is handled by the CLI during startup. You retrieve the necessary local environment variables and configure your application, such as adding NEXT_PUBLIC_ variables to your .env.local file.

The best way to develop Supabase Edge Functions offline is by running the complete local Supabase stack in Docker. This provides the necessary local Auth, Storage, and Realtime dependencies, allowing faster iteration without network latency.
