How to Handle Routing With Express

Learn how to handle routing with Express, the Node.js framework.

Express is a Node.js framework that is built entirely to run JavaScript code on the server.

Express provides and makes it easy to set up a backend authored application architecture with JavaScript. It is syntactically easy to learn, and it removes some complexities of Node.js.

Routing refers to how an application’s endpoints (URIs) or paths respond to different client requests. Routing is simply configuring other application endpoints to do certain things when a given condition is met.

When setting up routes, we have to associate them with the different methods.

Different methods include

GET — get information from a specific endpoint

POST — create and send data

DELETE — delete data

PUT — update information

Simple routing implementation

app. method (path, handler)

Method- (post, delete, get, put)

Path — Specifies the URL or the route that is to be hit

Handler — Refers to the function that will be run when the particular route or the path is hit.

How to Handle Routing With Express

Node JS — Router and Routes

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.

  2. Creating a simple Server with Express JS

  4. Organizing all routes in a Separate file

  1. Creating a Node JS Project

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

expressjs.com

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

Learn Express JS by building a Project - Routing

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.
