Building Your First REST API with Node.js and Express

REST APIs are the backbone of nearly every modern application. If you are learning full stack development, building one from scratch is the fastest way to understand how the frontend and backend actually talk to each other.

Start with a single resource — say, "students" — and implement the four core operations: create, read, update, and delete. Use Express routers to keep your code organized by resource rather than dumping everything into one file.

Once the basic CRUD works, add validation middleware and proper error handling. This is the difference between a tutorial project and something that survives contact with real users.

Finally, write a few tests with a tool like Jest or Supertest. Employers consistently mention that candidates who can demonstrate testing discipline stand out in technical interviews.
