Set up a Node & Express Server in 1min | Javascript Backend Tutorial 2023

In this tutorial, we will learn how to quickly set up a Node.js and Express server in just 1 minute. Node.js is a popular runtime environment that allows you to run JavaScript code outside of the browser, while Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.

Step 1: Install Node.js

First, you need to install Node.js if you haven’t already. You can download and install it from the official website. Once installed, you can check the version using the following command:

node -v

Step 2: Create a new directory

Open your terminal and create a new directory for your project:

mkdir my-express-server

Step 3: Navigate to the directory

Go into the directory you just created:

cd my-express-server

Step 4: Initialize a new Node.js project

Run the following command to initialize a new Node.js project:

npm init -y

Step 5: Install Express

Install Express by running the following command:

npm install express

Step 6: Create a server file

Create a new file called index.js and add the following code:


const express = require('express');
const app = express();

app.listen(3000, () => {
console.log('Server is running on port 3000');
});


Step 7: Run the server

Run the server using the following command:

node index.js

Open your web browser and navigate to http://localhost:3000. You should see the message “Hello, World!” displayed on the page.

Congratulations! You have successfully set up a Node.js and Express server in just 1 minute. You can now start building your backend applications using JavaScript.
