How to migrate an application from AngularJS to React and Redux

In BigPanda, we have been utilizing AngularJS for quite a while, and after some time we kept running into a similar issue a ton of programming ventures do - the greater our codebase got, the harder it was to keep up. Without a doubt, it wasn't all AngularJS's fault — a parcel of our issues was caused by an absence of clear structure standards and best practices, which after some time brought about tangled, coupled code that was extremely delicate and hard to test.

One of our most serious issues was the issue of state the executives, explicitly sharing a state between numerous segments in a way that didn't emphatically couple them. Without a reasonable formula, we wound up with a hodgepodge of $scope.$watch, $scope.$broadcast and partook in-memory stores kept in AngularJS administrations. After some time we thought of our own Redux-like state the executive's design, which helped when composing new highlights, however keeping up more established regions of the code was as yet excruciating. This, joined with some execution issues and the way that AngularJS was never again being effectively created, made us investigate whether a total revamp would be doable. 

Since we're a quick moving startup and couldn't bear to quit chipping away at highlights while we modify everything, we expected to figure out how to complete a continuous movement, with the goal that new highlights could be written in some new structure and existing highlights could be gradually supplanted after some time. To the extent system alternatives, we investigated Angular, React and Vue, and after a great deal of research and dialogue, we chose to React + Redux was the best fit for us. 

So now we expected to discover: might we be able to run Redux-associated React segments in AngularJS applications, and do it such that will enable us to in the end dispose of all inheritance AngularJS code? For this, there were a couple of issues we expected to discover an answer for: Get More Info On AngualrJS Online Course

Embeddings React parts into AngularJS layouts 

For this, we utilized an accommodating outsider library called react2angular. This gives us a chance to envelop our React segments by AngularJS segments, with the goal that they can be utilized consistently in any of our AngularJS layouts. This is the thing that it would seem that: 

import { react2angular } from 'react2angular'; 

import UserMenu from 'respond/format/topbar/parts/UserMenu'; 

angular.module('bigpanda').component('userMenu', react2angular(UserMenu)); 

Passing our Redux store to React parts 

Alright, so we can show React segments in AngularJS, however, how might we pass the Redux store to them? In great React-Redux applic, actions the proposal is to utilize a Provider segment to wrap the root segment, which ensures the store is passed to the setting of each kid part. In a half and half application like our own, this wouldn't work since there isn't one root React part, and wrapping every segment with a supplier independently would be too standard y. Rather, we chose to utilize ng-redux, so it's AngularJS's duty to pass the store to the React segments: Read More Info On Angularjs Online Training Bangalore

import { rootReducer, rootEpic } from '../../respond'; 

angular.module('bigpanda').config(($ngReduxProvider) => { 

const epicMiddleware = createEpicMiddleware(rootEpic); 

$ngReduxProvider.createStoreWith( 

rootReducer, 

[epicMiddleware] 

); 

} 

Furthermore, now our past precedent resembles this: 

import { react2angular } from 'react2angular'; 

import UserMenu from 'respond/design/topbar/parts/UserMenu; 

angular.module('bigpanda').component( 

'userMenu', 

react2angular(UserMenu) 

); 

angular.module('bigpanda').controller('UserMenuCtrl', UserMenuCtrl); 

work UserMenuCtrl($ngRedux) { 

this.store = $ngRedux; 

} 

Thus now we can send the Redux store as a property to our React parts. 

Directing to React parts 

The last advance is steering specifically to React segments. We use UI-Router, so our first intuition was to utilize respond half and half. Shockingly, this task is in its beginning periods and was unreasonably surrey for us, so all things considered react2angular demonstrated valuable once more - Info On AngualrJS Online Course Hyderabad

import { react2angular } from 'react2angular'; 

import PersonalSettings from './parts/PersonalSettings'; 

angular.module('bigpanda').component( 

'personalSettings', 

react2angular(PersonalSettings) 

); 

send out const appSettingsPersonal = { 

url: '/individual', 

sees: { 

'settings-site visit': { 

layout: '<personal-settings store="store"/>', 

controller: ($scope, $ngRedux) => { 

$scope.store = $ngRedux; 

} 

} 

} 

}; 

What we're doing is enclosing the React segment by an AngularJS segment, and after,r that we course to an inline-layout that utilizes that AngularJS segment. 

So now that we realized it was conceivable to get a crossover AngularJS + React-Redux application working, we expected to settle on the best way to structure our new React-Redux code such that will permit us as effortless a movement as would be prudent, while likewise making a point not to blend the React-Redux code with the AngularJS code. I'll talk about this in my next post. Read More Info On AngualrJS Online Training Hyderabad
