expressjsHow do I set up a project using Express.js and GitHub?

1. Create a repository on GitHub:

   • Go to GitHub and log in with your credentials.
   • Click on the plus icon in the top right corner and select New repository.
   • Enter the repository name and click Create repository.

2. Clone the repository to your local machine:

   • Copy the repository URL from the GitHub page.
   • Open the terminal and navigate to the folder where you want to clone the repository.
   • Enter git clone <repository-url> and press enter.

3. Initialize a new Node.js project:

   • Navigate to the repository folder.
   • Enter npm init and press enter.
   • Follow the instructions to create a package.json file.

4. Install Express.js:

   • Enter npm install express --save and press enter.
   • This will install Express.js and add it to the package.json file.

5. Create an app.js file and add the following code:

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

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

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

• This will create an Express.js server that listens on port 3000 and responds with Hello World! when the root URL is accessed.

6. Start the server:

   • Enter node app.js and press enter.
   • This will start the Express.js server.

7. Access the server:

   • Open your browser and go to http://localhost:3000
   • You should see the Hello World! message.
