NestJS

NestJS is a TypeScript framework for building structured Node.js back ends, APIs and content services. Articles under this tag explain how to add an RSS or Atom feed to a NestJS application. They cover services and controllers, response headers, absolute URLs behind reverse proxies and caching with ETags. Testing with Supertest and validating the finished feed are covered as well. Each guide ends with how to use the feed for automatic social posting.
