Node.js Backend Architecture Typescript - Learn to build a backend server for production ready blogging platform like Medium and FreeCodeCamp. Main Features: Role based, Express.js, Mongoose, Redis, Mongodb, Joi, Docker, JWT, Unit Tests, Integration Tests.
A teaching project that shows how to wire up a production-ish Express/TypeScript backend: JWT auth with refresh tokens, role-based access, Redis caching, Mongoose repositories, and a layered 3RE architecture. It targets developers learning backend patterns, not teams starting a real product.
The repository/model split is done right — Mongoose models never leak into route handlers, and every DB call goes through a typed repo class. The auth flow is solid: separate access/refresh tokens, a Keystore collection for revocation, and RS256 signing with real PEM keys included as examples. Test coverage mirrors the source tree with unit and integration tests co-located per feature, and the Docker Compose setup wires Mongo + Redis + a dedicated test runner container so `docker-compose up` actually works. Zod validation is applied at the route boundary before anything touches the DB.
The RSA private key ships committed in the repo (`keys/private.pem.example`) — fine for a demo, actively dangerous as a copy-paste template since beginners routinely forget to replace it. There's no pagination implementation despite the project claiming production readiness; the blog list endpoint will scan the entire collection once you have real data. MongoDB with Mongoose is a poor fit for a relational domain like blogging (users, roles, posts, tags all want joins), and the schema design bakes that in. The Docker image runs as root with no USER directive, which is a basic container hardening miss that undermines the production-ready framing.
