Front End Frameworks

1. React

The first place in our list of top JavaScript frameworks for 2019 without a doubt goes to React JS. React is a highly efficient and declarative JavaScript library used for building interactive UIs. It was created by Facebook engineer Jordan Walke and launched in May 2013. In the past 5 years, React has overtaken rival Angular JS and firmly established its dominance. React is used to create reusable user-interface components for each state, that can automatically update and render data without the need of reloading the page. Remember though, that React is a library and not technically a framework. It is mainly used to handle “V” (view) layer in the MVC(Model View Controller) model for web and mobile apps. Apart from web applications, React can also be used to create native mobile application supported by both android and iOS. With so much to offer, React JS reigned 2018 over other frameworks and I believe React JS will continue to dominate in 2019 too.

Usage Statistics

  • 475k websites on the web are powered by React.
  • 64.8% of javascript developers are currently using React.
  • Ranked 1st most popular front-end javascript framework in State Of JS survey.
  • Github – 120.5k stars, 21k forks and 1200 contributors.

Why REACT Is One Of The Top JavaScript Frameworks For 2019?

  • High performance – React is renowned for its high efficiency and flexibility. It can be easily integrated with other frameworks without any hassle. Can be used for both client side as well as server side.

  • Abundant Resources – As react is maintained by Facebook, there is a huge trove of documentation and resources available on the web which makes learning curve of react much smoother than its chief rival AngularJS.

  • Backward Compatibility – Transitioning or migrating from older to new versions is fairly easy in react using CodeMods.

  • Easy to maintain component structure – Component based architecture helps to increase reusability to code and ease of maintenance in large scale projects.

  • Rich community – React has close to 1300 contributors on GitHub which is more than any other library/framework.

  • Unidirectional Data Flow – One way/Unidirectional downward only data binding in react via flux controls helps to make sure that any changes made to child element structure don’t affect the parent element structure

Cons Of Using REACT

  • Bloated and complex – Many developers might find react too complex and bloated for their purpose as compared to Vue JS. Added complexity that coms align with react might be unnecessary for small scale projects.

  • JSX – The use of JSX adds another layer of complexity. JSX is a pre-processor, it adds XML syntax extension to JS. Although JSX helps to code react in a safer and faster manner, it is difficult to grasp for new developers.

  • Need for Assembly-Tools – React requires a wide array of assembly tools to function properly and be compatible with other libraries and frameworks.

  • SEO problems – webpages built with react are known to face issues with indexing by search engine crawlers/bots.

2. Vue

Holding the second place on top JavaScript frameworks for 2019 is Vue Js. Vue is an open source javascript framework meant to streamline UI design. It was created by Evan You and released in 2014. The last couple of years have a witnessed an explosion in popularity of Vue which has grown by leaps and bounds outpacing AngularJS rival framework by google in 2018 State of JS survey.

The key focal point of attraction of Vue is its progressive nature which helps it to adapt to developer’s needs. It is built on concepts from other frameworks and libraries like angular and react and offers a compact lightweight solution incorporating all the best features and practices.

Usage Statistics

  • 64k websites are powered by Vue.
  • 28.8% of javascript developers are currently using vue.
  • Ranked 2nd most popular front-end javascript framework in State Of JS survey.
  • Github – 125k stars, 18k forks and 253 contributors.

Why VUE.JS Is One Of The Top JavaScript Frameworks For 2019?

  • Fast Configuration: Vue has an inbuilt MVC model which makes configuration quick and easy compared to angular and react.

  • Flexibility: Flexibility and modular nature of Vue helps developers with past experiences on other frameworks and libraries to quickly adopt Vue with minimal effort.

  • Easy Learning curve: Learning curve of Vue is much easier than Angular and react. Only knowledge of HTML and JavaScript is required.

  • Lightweight Size: Vue is highly lightweight and compact in size compare to all other major JavaScript frameworks like angular and react. Compressed version of Vue is only 18 kb in size.

  • Integration Capability: Vue can be used to build both SPAs and large-scale complex applications as well with easy integration with server-side frameworks like Laravel, Symfony Django etc.

  • Transitions: Vue makes it easy to add transitions to elements when the are added or removed from the DOM.

Cons Of Using VUE

  • Poor Support: Vue doesn’t offer a big resource collection to new users on a scale similar to that of angular and react. Considering a comparatively lower market share, developers who are new to Vue js might not find adequate support and resources.

  • Small Community: A large chunk of Vue developer community is from non-English speaking eastern European countries. Community engagement used to be fairly low, However that is expected to change in 2019 as Vue saw a mammoth rise in popularity by the end of 2018.

3. Angular

Angular is a front end web applications framework based on typescript. AngularJS or Angular 1 was built by google engineers when Misko Hevery and Adam Abrons and launched in 2010 while angular 2 was launched in 2016.

Angular is arguably the oldest modern javascript framework that let users built dynamic interactive websites. In spite of being the oldest, Angular JS is still considered as developer’s first choice for a heavy volume of developers worldwide which is why it is one of the top JavaScript frameworks for 2019.

Angular enabled developers to build highly efficient and robust Single page applications rather than static HTML websites. Google completely revamped the original framework and released a radically different and improved typescript Angular 2. Angular 2 introduced component-based architecture, improved dependency injection, logging service and inter-component communication.

The latest current version 7 was launched in September 2018 and new updates are released every 6 months. Version 7 has introduced vast improvements in Performance, Angular Material & CDK, dependencies for Typescript version 3.1, RxJS 6.3, Node version 10. Virtual Scrolling and content projection have also been introduced.

Usage Statistics

  • 350k websites on the web are powered by AngularJS/Angular2+ versions.
  • 23.9% of javascript developers are currently using Angular.
  • Ranked 3rd most popular front-end javascript framework in State Of JS survey.
  • Github – 44.5k stars, 11.5k forks and 840 contributors.

Why ANGULAR Is One Of The Top JavaScript Frameworks For 2019?

  • Data bindingApart from 2-way binding, angular 2 and beyond support 3 other types of data-binding namely – one-way property binding, event binding and interpolation.

  • Enhanced RXJS has led to lightning fast compilation time of approx. 2.9 sec and modified start HttpClient.

  • Abundant resources and support: Google offers a rich treasure trove of resources and rolls out new updates and improvements every 6 months.

  • Support for Progressive web applications: Angular is the first framework to integrate features for development of progressive web applications.

  • MVVM (Model-View-ViewModel) allows developers to work on the same application and data pool in isolation.

  • Native mobile app: NativeScript powered by angular enables development of native mobile apps for both iOS and android.

Problems with Angular.

  • Difficult Syntax: Angular has made a big leap in terms of syntax complexity after adopting TypeScript in angular2 and beyond. Yet it poses a steep learning curve for anyone making a transition from vanilla JS or jQuery.
  • Migration: It is complex to migrate from older angular version especially from AngularJS to angular 7.
  • Steep learning curve: out of the three top javascript front-end frameworks, Angular has the steepest learning curve and suffers from a very high rate of abandonment. A large base of angular users has moved to Vue and react.
  • Knowledge of MVC: A crucial prerequisite for using angular is the need to have a thorough understanding of model view controller architecture
