Build Your First Node.js Server Step by Step | Day 4 | TechFocusss

Build Your First Node.js Server Step by Step.
When you start learning Node.js, the biggest confusion is not the theory — it’s the actual code.
Where do we start? What does each line do? How does the server really run?

In this video (Day 4 of our Node.js series), we build a real Node.js server from scratch and explain every single line of code in a very simple way.

✅ In this video, you will learn:

How to use the built-in http module

How createServer() actually works

What req and res really mean

Why res.end() is important

What is a port and why we use 3000

How to run your server using the terminal

How to see Hello World in your browser

By the end of this video, your first real backend server will be live on:
http://localhost:3000
