Drizzle ORM integrates into NestJS via a dedicated module that wires the database connection, exposes query builders, and connects to your controllers and services. Set up a Drizzle provider in NestJS, inject it into your services, and use it to access Postgres tables across your application's repository and service layers.

Yes. NestJS supports both REST and GraphQL API patterns natively. Drizzle ORM works with either: define your schema once, then query it from REST controllers or GraphQL resolvers, using the same services and repositories for data access.

NestJS provides guards, decorators, and middleware for authentication and authorization. Integrate these with Drizzle ORM by querying user data and permissions from Postgres in your service layer, then applying guards to routes or GraphQL fields to enforce access control.

NestJS supports unit and integration testing via Jest. Mock Drizzle services in unit tests, or use test databases and transactions for integration tests. Test your controllers, services, and repository patterns independently, then verify end-to-end API behavior.

Drizzle ORM includes migration tools that run independently of NestJS. Define migrations in your schema, generate them with Drizzle's CLI, version them in source control, and run them during deployment or development setup before starting your NestJS application.

Use NestJS modules to group related controllers, services, and repositories. Each module owns its data access layer via repositories injected into services, which serve controllers or GraphQL resolvers. Drizzle queries live in repositories; business logic lives in services.
