Building HTTP Server in NodeJS
MindCraft Backend Web Dev - Master Node JS + Express Lecture 7
Course by: MindCraft

In this lecture, we will create our own HTTP web server using Node.js and its built-in HTTP module. By the end of this session, you’ll understand how to handle HTTP requests and responses, and how to serve web pages using Node.js.

Introduction to Node.js and the HTTP Module

Node.js is a powerful JavaScript runtime built on Chrome’s V8 JavaScript engine, allowing developers to run JavaScript on the server side. We'll begin by introducing the HTTP module, a core component in Node.js that provides the functionality to create HTTP servers and handle requests and responses.

Setting Up Your Node.js Environment

Before diving into code, we’ll quickly review how to set up your Node.js environment. This includes installing Node.js, initializing a new project with NPM, and ensuring you have everything in place to start building your server.

Creating Your First HTTP Server

We’ll then move on to creating your first HTTP server. You’ll learn how to use the HTTP module to create a server that listens on a specified port and responds to incoming requests. We’ll walk through the basic structure of an HTTP server in Node.js, explaining each part of the code as we go.

Handling HTTP Requests and Responses

Understanding how to handle HTTP requests and responses is crucial for building web servers. We’ll explore how to manage different types of requests (GET, POST, etc.), how to parse incoming data, and how to send appropriate responses. You’ll also learn how to serve static files like HTML, CSS, and JavaScript.

Serving Dynamic Content

Next, we’ll discuss how to serve dynamic content using Node.js. You’ll see how to use templates or directly embed JavaScript in your server responses to generate dynamic web pages. This section will cover the basics of routing and rendering content based on the URL path.

Error Handling in Node.js Servers

Building a robust server requires good error handling practices. We’ll cover how to manage errors that might occur during the request-response cycle, such as handling 404 errors, server errors, and other common issues. You’ll learn how to create custom error pages and ensure your server remains stable.

Testing Your HTTP Server

Finally, we’ll show you how to test your HTTP server using tools like Postman or your browser. We’ll go through a few test cases to ensure your server responds correctly to various types of requests and handles errors gracefully.
