Backend API Development

Instructions

1. Route Creation

   • Define RESTful routes (GET, POST, PUT, DELETE)
   • Group routes by resource
   • Use clear and consistent URL patterns

2. Request & Response Handling

   • Parse request bodies, params, and query strings
   • Validate incoming data
   • Send structured JSON responses
   • Handle errors with proper HTTP status codes

3. Database Connectivity

   • Connect to a database (SQL or NoSQL)
   • Implement CRUD operations
   • Use environment variables for credentials
   • Handle connection errors gracefully

Best Practices

• Follow REST conventions
• Keep controllers thin and logic modular
• Use async/await for database operations
• Never expose sensitive data in responses
• Centralize error handling

Example Structure

Copy// routes/user.routes.js
import express from "express";
import { getUsers, createUser } from "../controllers/user.controller.js";

const router = express.Router();

router.get("/users", getUsers);
router.post("/users", createUser);

export default router;
