Auto-generate NestJS application documentation. Codec8 reads your decorators, module structure, DTOs, and guards to produce complete API and architecture documentation.
NestJS's decorator-heavy architecture is powerful but opaque. Without documentation, understanding which modules are loaded, which guards protect which routes, and what each DTO validates requires reading every file in the project.
Tailored documentation features for NestJS codebases
Documents @Controller routes with @Get/@Post/@Put/@Delete methods, DTOs, and guards
Generates NestJS module dependency graph showing imports, providers, and exports
Documents @Injectable services with their dependencies and methods
Produces Swagger/OpenAPI documentation supplement with auth guards and role requirements noted
