Build your first web server! Learn to create a raw HTTP server with Node.js without any frameworks. This hands-on tutorial focuses on practical implementation of http server basics concepts.
HTTP Server Basics
Node.js was designed to be a web server. Unlike PHP (which needs Apache/Nginx), Node.js is the server.
Let's build one from scratch using the built-in http module.
1. Creating a Server 🖥️
The http.createServer method takes a callback function that runs every time a request comes in.
2. Handling Routes (URLs) 🛣️
The req.url property tells us what page the user wants.
3. Handling Methods (GET vs POST) 📨
The req.method property tells us the action (GET to read, POST to create).
4. The Problem with Raw Node.js 😫
Did you notice how much code we wrote just for simple routing?
- We have to manually check
req.url. - We have to manually check
req.method. - We have to manually stringify JSON.
- We have to manually handle streams for POST bodies.
This is why we use Frameworks like Express.js.
