Installation of Express.js

Introduction

Installing Express is incredibly simple. Since it is just a Node.js package, you will use npm (Node Package Manager) to add it to your project.

Prerequisites

Before installing Express, you must have Node.js installed on your machine. You can verify this by running:

node -v
npm -v

Creating a Project

First, create a new directory for your project and navigate into it:

mkdir my-express-app
cd my-express-app

Next, initialize a new Node.js project. This will create a package.json file.

npm init -y

Installing Express

Now you can install Express as a dependency in your project:

npm install express

This command downloads Express and its dependencies into the node_modules folder and adds it to your package.json.
