Express Setup🌱 Beginner

To start using Express, you simply need a Node.js project and the express NPM package. Setting it up takes less than a minute.

What is Required?

Express is not a standalone software; it is a standard library installed via NPM. Therefore, you must have Node.js and NPM installed on your machine before beginning.

Why Use package.json?

When you install Express, it needs to be tracked. The package.json file acts as the official manifest for your project, recording exactly which version of Express your app relies on so other developers can run your code perfectly.

How to Install and Run

Open your terminal in an empty folder and run these exact commands:

# 1. Initialize a new Node project (creates package.json)
npm init -y

# 2. Install Express as a dependency
npm install express

# 3. Create your main server file
touch index.js

Once you write your server code in index.js, you can run it:

# Start the Node server
node index.js
