The NestJS documentation problem

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.

Frequently asked questions about NestJS documentation

Does it work with NestJS microservices as well as REST APIs?

Yes. For microservice projects, Codec8 documents the transport layer (TCP, Redis, NATS, Kafka), message patterns, and event handlers alongside regular REST endpoints.

Can it document NestJS GraphQL modules using @nestjs/graphql?

Yes. Codec8 detects @Resolver, @Query, @Mutation, and @Subscription decorators and generates GraphQL schema documentation alongside any REST endpoints in the same project.

How does it handle NestJS projects using Prisma or TypeORM?

Codec8 reads your Prisma schema or TypeORM entities and generates database model documentation that links directly to the service layer that uses each model.
