To use NestJS dependency injection, define providers in module metadata and inject them into controllers via constructor parameters. This reference consolidates official patterns for configuring providers, modules, and controller wiring.

NestJS modules organize application structure by grouping related controllers and providers into cohesive feature areas. This guide provides official architecture patterns for maintaining scalable module boundaries in production codebases.

NestJS guards, pipes, and interceptors process requests sequentially for authorization, data transformation, and response mapping. This reference consolidates official examples demonstrating how to combine these components for robust request handling.

NestJS supports building microservices, GraphQL APIs, and WebSockets within its modular architecture. This guide aligns with official documentation to provide ready-to-use patterns for implementing these communication protocols.

NestJS OpenAPI and Swagger configuration involves using the dedicated module to generate API documentation from controller decorators. This reference provides official guidance for setting up security schemas and generating Swagger UI.

NestJS is ideal for onboarding teams and rapid scaffolding due to its strict modular architecture and official documentation alignment. This reference provides standardized patterns to ensure consistent implementations across projects.
