Build RESTful APIs with Express.js ๐Ÿš€

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}`));
Enter fullscreen mode Exit fullscreen mode
  1. Define Routes:

    • Use app.get(), app.post(), app.put(), app.delete().
  2. Middleware:

   app.use(express.json());
Enter fullscreen mode Exit fullscreen mode
  1. CRUD Operations:

    • Implement Create, Read, Update, Delete endpoints.
  2. Test:

    • Use Postman or Insomnia to test endpoints.

Create robust, scalable APIs with Express.js! Happy coding! ๐Ÿ’ปโœจ #ExpressJS #RESTfulAPI #NodeJS #WebDev
