Express.js: A Server-Side JavaScript Framework

Youโ€™re probably aware that JavaScript is the programming language most often used to add interactivity to the front end of a website, but its capabilities go far beyond thatโ€”entire sites can be built on JavaScript, extending it from the front to the back end, seamlessly.

Express.js and Node.js gave JavaScript newfound back-end functionalityโ€”allowing developers to build software with JavaScript on the server-side for the first time. Together, they make it possible to build an entire site with JavaScript: You can develop server-side applications with Node.js and then publish those Node.js apps as websites with Express.

Because Node.js itself wasnโ€™t intended to build websites, the Express framework is able to layer in built-in structure and functions needed to actually build a site. Itโ€™s a pretty lightweight framework thatโ€™s great for giving developers extra, built-in web application features and the Express API without overriding the already robust, feature-packed Node.js platform. In short, Express and Node are changing the way developers build websites.

Express.js Basics

  • Server-side web and mobile application framework
  • Language: written in JavaScript
  • Express builds:
    • Single-page, multi-page, and hybrid mobile and web apps
    • Common back-end functions for web applications
    • APIs (application programming interfaces)
  • Templating engines: Express comes with two templating engines, Jade and EJS, which facilitate the flow of data into a website structure.
  • MVC pattern: Express supports the Model-View-Controller architecture, a really helpful way to build websites in a model-driven format.
  • Platform: Node.js
  • Operating system: Itโ€™s cross-platform, so itโ€™s not limited to one OS.
  • The Express Generator lets you create complex applications quickly.

Express.js and the MEAN stack

Express.js is the โ€œEโ€ in the MEAN software stack, where it runs alongside the MongoDB database, the Node.js environment, and the AngularJS front-end framework.

Every software stack includes an operating system, database, server, and development platformโ€”everything you need to build and run the back end of a website or web application.

Unlike other traditional stacks, the MEAN stack is entirely JavaScript-powered, thanks to Node.js, the JS development environment that gives JavaScript back-end functionality.
