Express.js: A Robust Framework for Node.js Web Applications1

Hello web developers and designers! Today we are going to dive into one of the most popular unopinionated web frameworks, Express.js2. This fantastic Node.js web application framework provides a robust set of features that can facilitate the development of web and mobile applications.

What is Express.js?

Express.js is a minimal and flexible Node.js web application framework. It provides a robust set of features that makes handling HTTP requests and routing easier. Express.js is also the underlying library for a number of other popular Node.js web frameworks.

Key Features of Express.js3

  • Simplicity: Express.js is easy to set up and personalize. This makes it a great choice for developers wanting to design their applications their own way.

  • Routing: Express.js provides a robust set of functions for routing HTTP requests. This makes it easier to design web APIs and handle different HTTP methods.

  • Middleware: Middleware functions are a fundamental part of applications in Express. These functions have access to the request object (req), the response object (res), and the next middleware function in the application’s request-response cycle4.

  • Template Engines: Express.js uses Jade as a default template engine. You can set any other template engine like ejs, hbs, pug, etc.

  • Error Handling: Error handling is made easy in Express.js. It comes with a default error handling middleware function.

Getting Started with Express.js1

Before you can start using Express.js, you need to install Node.js and npm (Node Package Manager) on your system. Once these prerequisites are installed, you can install Express.js by running the following command:

npm install express --save

To verify the installation, you can create a simple server with Express.js. Here is an example:

const express = require('express'); const app = express(); app.get('/', function (req, res) { res.send('Hello World!'); }); app.listen(3000, function () { console.log('Example app listening on port 3000!'); });

This script will start a server and listen on port 3000 for connections. When you access http://localhost:3000/ in a web browser, you should see 'Hello World!' on the page.

Why Choose Express.js?

There are several reasons why Express.js has become the most popular Node.js web app framework2:

  • Unopinionated: Express.js doesn't force you to follow any particular coding or structuring practice - it lets you decide how your app should be organized.

  • Flexible: Express.js is incredibly flexible. Not only does it let you structure your app your way, but it also lets you choose almost any other Node.js module for tasks like handling HTTP requests and managing user sessions.

  • Scalable: Apps built with Express.js are scalable and can handle increasing amounts of workload in a sustainable manner.

Besides, Express.js is widely used in the industry. Many reputable companies are using Express.js for their web applications1.
