Nodejs Day4: Building a Basic Backend with Pure Node.js

Are you ready to take your Node.js skills to the next level? In this tutorial, we will be diving into building a basic backend with Pure Node.js. This is a great way to understand the fundamentals of backend development and gain a deeper understanding of Node.js.

Getting Started

Before we start building our backend, make sure you have Node.js installed on your machine. If you haven’t already done so, head over to the Node.js website and follow the instructions for installing Node.js. Once Node.js is installed, you’re ready to get started!

Setting Up Your Project

First, create a new directory for your project and navigate into it using your terminal. Once you’re in the project directory, create a new file called “app.js”. This will be the main file for our backend.

Building Your Backend

Now that our project is set up, it’s time to start building our backend. In the “app.js” file, we can start by creating a basic server using Node.js’s built-in http module. We can then define a simple route and send a response to the client.

  
  const http = require('http');

  const server = http.createServer((req, res) => {
    if (req.url === '/') {
      res.write('Hello, this is the homepage');
      res.end();
    } else if (req.url === '/about') {
      res.write('About us page');
      res.end();
    } else {
      res.write('Page not found');
      res.end();
    }
  });

  server.listen(3000);
  
  

Testing Your Backend

Once your backend is set up, you can test it out by running the “app.js” file in your terminal using Node.js. Open up your web browser and navigate to “http://localhost:3000” to see your backend in action. You should see the message “Hello, this is the homepage” displayed on the page. You can also test out the other routes you defined to see the different responses.

Congratulations! You have now built a basic backend with Pure Node.js. From here, you can continue to expand and enhance your backend by adding more routes, handling different types of requests, and incorporating databases and other external services.

Keep practicing and experimenting with Node.js to further develop your backend development skills. Happy coding!
