Why Switch from AngularJS to React

React over AngularJS:

Well, earlier in 2011 when coding becomes clutter with the JQuery, then the emergence of AngularJS turns out to be boon. With the better management, rapid development and lots of other dynamic features AngularJS enter the market. AngularJS solved numerous coding related problems of developers and it became the very prominent choice of developers. But, as we all know that nothing is perfect, so with the more utilization some downsides of  AngularJS become more visible. The minus points that makes AngularJS not so perfect solution.

Downside of AngularJS

  • AngularJS depends on the DOM for execution. So, while default bootstrapping DOM files is scanned which eventually makes debugging and testing difficult.
  • AngularJS does not have a package manager and dependency resolver of its own. But lately, dependency injection has introduced by AngularJS. But, it isn’t official AngularJS DI implementations using RequireJS.
  • It is very interesting to use two-way binding offered by AngularJS, but in reality, it became utterly complicated that in the end, you can’t handle it properly.
  • AngularJS operation has to be followed in chronological order, otherwise, it might not provide the desired result.
  • Learning AngularJS isn’t an easy task as it involves lots of stuff including modules, controllers, directives, scopes, templates, linking functions, filters, and dependency injection.

The need of React:

Pretty much world shocked after the launch of React in 2013. The Facebook and Instagram are using this one-way flow application tool. It seems totally unreal in the beginning but nowadays numerous developers are shifting towards React.  Well, React is based on the principles like “one-way data flow” and “Virtual DOM”. The React re-thinks the best practices in web development. React also encourages one-way data flow, but it doesn’t prove that you should ditch AngularJS and shifts to React. So, to justify this shift let’s look at few advantages of React.

Advantages of React:

  • React is incredibly fast then the other frameworks. As React doesn’t directly work with the DOM. It has Virtual DOM between the JavaScript and actual DOM, which immensely improves the speed.
  • In React every component is widgets in UI. With the UI every component can be tested isolation and developed frequently.
  • Okay, React has Flux. Flux makes development simpler and makes it easier to track down and fix bugs. It can be implemented in other frameworks as well. Alex Rattray has a very nice implementation of Flux using Backbone Collection and Model in React.
  • Modern web applications work very differently and JavaScript is necessary to develop them. And React understand the modern day’s requirements very well.
  • React is built with Browserify, but if you’re looking to inject image assets and compile LESS or CoffeeScript, then probably Webpack stands as a better option.

Dramatic Conclusion:

Well, if you had worked with AngularJS before, then you are going to hate to React first.  As it is the polar opposite to AngularJS and has only one-way flow data. But, as you began to use React you will realize the benefits of Flux design and its framework less beauty. Facebook, Instagram, and Github have already become the fan of its beauty, and now that’s enough example to shift towards React.
