REST API with Express

Building a REST API with Express involves creating routes that follow REST principles, mapping HTTP methods like GET, POST, PUT, and DELETE to specific resource actions.

Structuring Routes

Organizing routes by resource and separating logic into controllers keeps the codebase clean and easier to maintain as the API grows.

Working with Data

REST APIs built with Express often connect to databases like MongoDB or PostgreSQL to persist and retrieve data for each request.

Error Handling

Proper error handling middleware ensures that API consumers receive clear, consistent error responses when something goes wrong.
