Creating a Server in Express JS
Express is a popular web framework for building web applications in Node.js. One of the key features of Express is its ability to easily create a server to handle HTTP requests.
Setting up Express JS
To create a server in Express, you first need to install the Express framework. You can do this by running the following command in your terminal:
npm install express
Creating a Server
Once you have Express installed, you can create a server by writing the following code in a file named server.js:
const express = require('express');
const app = express();
const port = 3000;
app.get('/', (req, res) => {
res.send('Hello, World!');
});
app.listen(port, () => {
console.log(`Server is running on http://localhost:${port}`);
});
This code sets up a basic Express server that listens on port 3000 and responds with “Hello, World!” when a GET request is made to the root route (‘/’).
Running the Server
To start the server, you can run the following command in your terminal:
node server.js
After running this command, you should see a message in the console indicating that the server is running. You can then navigate to http://localhost:3000 in your browser to see the “Hello, World!” message.
Conclusion
In this article, we covered how to create a basic server in Express JS. Express provides a simple and efficient way to handle HTTP requests and build web applications in Node.js. By following the steps outlined above, you can quickly set up and run a server using Express.
