Node.js & Express.js Series | Chapter 6 | Hands-on Node.js Assignment

Welcome to Chapter 6 of our Node.js & Express.js Series! In this hands-on assignment, we will be diving into some practical exercises to solidify our understanding of Node.js.

Task 1: Create a Simple Node.js Server

For the first task, we will create a simple Node.js server using the built-in http module. We will listen on port 3000 and respond with a “Hello World” message when a request is made to the server.

    
      const http = require('http');

      const server = http.createServer((req, res) => {
        res.statusCode = 200;
        res.setHeader('Content-Type', 'text/plain');
        res.end('Hello Worldn');
      });

      server.listen(3000, '127.0.0.1', () => {
        console.log('Server running at http://127.0.0.1:3000/');
      });
    
  

Task 2: Create a Basic Express.js Application

Next, we will move on to creating a basic Express.js application. We will set up a simple route that responds with a “Hello Express” message.

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

      app.get('/', (req, res) => {
        res.send('Hello Express');
      });

      app.listen(3000, () => {
        console.log('Express app listening on port 3000!');
      });
    
  

Task 3: Create a RESTful API

In the final task, we will create a RESTful API using Express.js. We will set up endpoints for GET, POST, PUT, and DELETE requests, and implement the necessary logic to handle these requests.

    
      // Define endpoints for GET, POST, PUT, and DELETE requests
      // Implement the logic to handle these requests
      // Add necessary middleware for request validation and error handling
      // Start the Express server and listen for incoming requests
    
  

Once you have completed these tasks, you will have a solid understanding of how to work with Node.js and Express.js to build web applications and APIs. We hope you found this hands-on assignment valuable and gained practical experience working with these technologies.
