api-doc-generation

You can generate API documentation from NestJS controllers automatically by parsing decorators and DTOs. This process analyzes endpoints, parameters, request/response schemas, authentication, and status codes to create accurate RESTful API docs.

API documentation becomes outdated because manual updates lag behind controller modifications. Automating documentation generation directly from NestJS controller code ensures synchronization with endpoint additions, DTO changes, and parameter updates.

The best way to keep REST API docs in sync with code is to generate them directly from controller logic. By parsing decorators and DTOs from NestJS controllers, documentation automatically reflects endpoint modifications and schema updates.

Yes, you can extract request and response schemas from DTOs for API documentation. By leveraging file analysis tools to comprehensively parse NestJS DTOs, the documentation process captures detailed schemas, parameters, and authentication requirements.

Automated documentation generation works with existing NestJS controller decorators by parsing them directly. It analyzes your current codebase to extract endpoints, parameters, and status codes without requiring you to rewrite your controller logic.
