Build RESTful APIs with Express.js 🚀

Hey your instructor #KOToka here....

1. Setup:

   • Install Node.js & npm.
   • Initialize: npm init.
   • Install Express: npm install express.

2. Basic Server:
   

   const express = require('express');
   const app = express();
   const port = 3000;

   app.get('/', (req, res) => res.send('Hello World!'));

   app.listen(port, () => console.log(`Server running at http://localhost:${port}`));

1. Define Routes:

   • Use app.get(), app.post(), app.put(), app.delete().

2. Middleware:
   

   app.use(express.json());

1. CRUD Operations:

   • Implement Create, Read, Update, Delete endpoints.

2. Test:

   • Use Postman or Insomnia to test endpoints.
