Node.js has become more popular among developers over the last few years. Especially when you’re good at JavaScript, you don’t have to learn any other particular language for backend development because of Node.js. While having built-in packages, it also supports for 3rd party packages.

Hello all. In this blog, I am explaining how to perform routing with Node JS. Routing is one of the most important parts of any Web framework since it defines how our application should handle all the HTTP requests by the client.
Table of Content
Create a new directory and initialize node with the command npm init
.
mkdir helloworld
cd helloworld/
npm init -y
After executing the command, a package.json
file generated in the project’s root directory. This holds all the metadata relevant to the project.
On this file, we see something called scripts. This is the place where we add our own commands for the project. I am creating a new command which starts my server when I type npm start
. The script tells node that it should run the command node index.js
every time when I execute the command npm start
.
package.json
"scripts": {
"start": "node index.js",
"test": "echo \"Error: no test specified\" && exit 1"
},
2. Creating a simple Server with Express JS
Now let’s create our server. Here we are creating our server using Express.js
. Express JS is an open-source web framework for node JS. It is designing for building web apps and APIs. The below command installs express to our project.
npm install express --save
We are using express to create a new server that will be running on the port 8000. Also for the demonstration, I am creating a route that returns hello world.
index.js
var express = require('express');
var app = express();
app.get('/', function (req, res) {
res.send('Hello World!');
});
app.listen(8000, function () {
console.log('Listening to Port 8000');
});
Now start the server, you should see hello world being displayed in the browser.
npm start

In this video series, we are going to learn Express JS by building a project. Express is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications.
Along the way we are going to learn what is Express and how it works. Along with Express, we are also going to learn about other dependencies that are required for the backend. Finally, we will create an application that uses CRUD(create, read, update and delete) functionality.
In this part, we are going to learn how to create a route in express js.
