JavaScript Frameworks in 2022

The 5 Most Popular JavaScript Frameworks in 2022

1. Vue.js

Designed specifically to be more simple than AngularJS, Vue.js was released in 2014 as a front-end JavaScript framework for building user-interfaces and single-page applications. Its model-view-viewmodel architectural pattern is optimized for both front- and back-end development. Similarly to React, Vue.js supports native mobile app development through its sister software Vue Native. Vue.js consists of a core library and a secondary system of supporting libraries. Vue.js is one of the most straightforward JavaScript frameworks available, and is quickly gaining traction in the web development marketplace

Features

  • Tiny Size: Given its tiny size, applications developed in Vue.js are quicker to load and use less bandwidth than heavier applications.
  • Virtual DOM: Vue creates an in-memory data-structure cache. When we create a DOM object, a virtual DOM object, or clone, is created. Because of its memory, programmers don’t have to program every detail into every page. Multiple programmers can write code without causing any major changes to the project's roots. This saves developers time and reduces labor cost while creating a fast-running product with a smaller-than-usual footprint.
  • Single-file Components: Similar to React, everything in Vue is a component. This improves the efficiency of developing applications and increases load time in high-volume applications. 
  • Backwards Compatibility: Vue.js is future-proof. Historically, framework updates would often render applications in need of repair. The developers of Vue kept this in-mind by making Vue Version 3 completely backward compatible with Vue 2. This means less maintenance, and web applications that can potentially span decades.

2. Angular

Released in 2010, AngularJS was the original client-side JavaScript framework. It focused on sophisticated single page applications.  As of 2022, AngularJS is no longer supported by the Google Development Team which developed Angular in 2016 as a rewrite of AngularJS. Angular differs from its predecessor in, among other changes, its hierarchy of components, more modular interface, and greater backwards compatibility. Angular is our choice for real-time, highly interactive applications.

Features

  • TypeScript: This feature is paramount to frontend development in 2022 and beyond. TypeScript is fantastic for troubleshooting applications and detecting coding errors before they become bugs. It allows code to be compiled using ES5 and ES6 standards to support the latest browsers. TypeScript is just JavaScript with some additional features which reduce development time and allow for quick and accurate deployment of a project. 
  • Desktop: Angular supports development of desktop applications which can be used on a computer even while offline.
  • Code Splitting: Applications developed in Angular load the most important parts of their code first, and allow the other features to load second. This makes the start up time of these applications very fast.

3. Express.js

Express is a framework written in JavaScript for use with the Node.js runtime environment. It is designed for building all sorts of server-side web applications and APIs quickly and easily. Node.js offers powerful performance, while Express reduces the amount of hand-written code we need to complete a project. We partner Express with Node a majority of the time, which allows us to decrease the complexity of programming and reduce the time required to build an efficient application with either component. Express.js is used by Paypal, Fox Sports, and IBM.


Features

  • Full Stack JavaScript: The code of both front-end and back-end is JavaScript. Because of this, there is potential for one developer to create the full application. This saves you the cost of hiring two developers, as we often do for each side of the application.
  • Middleware: This is a part of the program that has access to the database, client request, and the other middlewares. It is the way Express is organized. Middleware-based applications allow offline communication between applications, communicate information in real-time, lower IT costs, and streamline business processes.
  • Faster Server-side Development: As opposed to heavier options such as the older DevExpress, Express.js has a lighter footprint and requires less code to develop high-quality applications. Additionally, many features of Node.js can be executed as ready-to-use functions in Express.js. These aspects of Express save the time, frustration, and expense of a heavier framework.

4. Svelte

Svelte was developed in 2016 as a lightweight, component-based, front-end JavaScript framework similar to Angular, Vue, or the React library. It is up-and-coming, but currently has a little less marketplace support than its alternatives. Svelte is a compiler, meaning it bundles components without using a framework script and works using Real instead of Virtual DOM. Like Express.js, Svelte requires developers to use Node.js. Svelte is often used for single page applications, low-power devices, and interactive visualization. It can be used for a project in its entirety, or just as one part of a whole.


Features

  • Tiny Size: Svelte was designed to be exceptionally small, and is the smallest of each of these other frameworks. Small size is important when space is a concern and also increases speed of performance.
  • Lack of Virtual DOM: Virtual DOM has its benefits, but so does compiling. Svelte is a compiler. It produces and optimizes code in one step, resulting in quick runtime, smooth transitions, and fast startup. Svelte takes care of updating the DOM without API as the middleman by changing the components themselves.
  • TypeScript: TypeScript is just JavaScript with some additional features which reduce development time and allow for quick and accurate deployment of a project. It is fantastic for troubleshooting applications and detecting coding errors before they become bugs.
  • Boilerplate-free: Most libraries and frameworks support reusable code using boilerplates and APIs. This reduces the amount of code we need to write, but the reusable code takes up space on the application. Svelte cleverly reduces the amount of code we need to write by getting rid of the boilerplate. It is able to do this because it is a compiler, and is therefore bound by different rules than framework-based software. For more about this feature, head on over to Svelte.

5. Google Web Toolkit

First released in 2006, Google Web Toolkit is the baby of Java and JavaScript. It is technically an AJAX framework, but was developed to allow us to create and maintain JavasScript front-end applications in Java. While it is the oldest framework on this list, it continues to maintain its popularity.  Looking at the past year, this framework is the second most popular on this list, coming in quite a bit lower than Angular on Google’s search trends. GWT is heavily supported by a number of open-source tools and is also becoming supported by newer frameworks, such as Vue.js which created VueGWT for use of some Vue components in GWT. While it is a tried and true tool, GWT can be more complicated than newer alternatives, and requires an experienced Java developer.


Features

  • User-support: Perhaps due to its time on the web, GWT has a larger number of tools and libraries than most other frameworks. This list continues to grow year by year, greatly extending and updating GWT”s features.
  • JavaScript Native Interface: Java developers enjoy greater flexibility and control over features with GWT’s support for mixing handwritten JavaScript in the Java source code.
  • GWT Compiler: The compiler is a tool which helps developers create clean code. It assists with in-lining, removes dead code, optimizes strings, and sets split-points in the code. One of the most useful features of the GWT Compiler is its ability to segment an application into multiple JavaScript fragments, resulting in a faster startup time.


Are We Missing Something?

As a simple definition, libraries are snippets of pre-built code that are used and reused to build a web application.  Libraries provide building blocks. Frameworks, on the other hand, are more like a blueprint or frame of a project. JavaScript Frameworks are a collection of pre-built code. Here is our research on the most popular JavaScript libraries.
