Back-end development with Node.js
Build servers and APIs.
📖 Key ideas
- Node.js runs JavaScript on the server.
- Express defines routes: app.get("/api/users", handler).
- REST APIs use GET, POST, PUT, DELETE and JSON.
- Middleware handles parsing, logging, auth.
- Alternatives: Django, Flask, Spring Boot, Laravel.
💡 Real-life example: The back end is the kitchen: takes orders (requests), cooks (logic) and sends dishes (responses).
