Create server with Express.js

Create server with Express.js

If you are looking for a way to build a server using JavaScript, Express.js is a great choice. It is a lightweight and flexible framework that makes it easy to develop web applications and APIs. Here are a few steps to create a server using Express.js:

Step 1: Install Express.js

The first step is to install Express.js. You can do this by running the following command in your terminal:

npm install express

Step 2: Initialize your project

Once you have installed Express.js, you can create a new project directory and initialize it using npm. In your terminal, run the following commands:

$ mkdir myproject
$ cd myproject
$ npm init -y

Step 3: Create your server file

Next, create a new file called server.js in your project directory. This is where you will write the code for your server.

const express = require('express');

const app = express();

app.get('/', (req, res) => {
  res.send('Hello World!');

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

Step 4: Start your server

Finally, start your server by running the following command in your terminal:

$ node server.js

Now if you go to http://localhost:3000 in your browser, you should see "Hello World!" displayed on the page.

There are many other ways to create a server with Express.js, such as using middleware or setting up routes. Be sure to check out the official documentation for more information.
