ng-react-state

Shared React State Hooks in Angular 1

Angular 1 Directives and factory with React Hooks to share and auto re-render state across React Components without props passing or parent hierarchies

Install

$ npm install ng-react-state

Usage

$ npm run start
//=> "http://localhost:3000"

With ngReact you can set React components into Angular1. But what about sharing state across all React Components? With shared-state-hook and ngReactState we can now access and change the same state that will auto re-render those components without passing props.

React shared State Component Angular1 Directive

const WelcomePage= props => {
    const [user, setUser] = useSharedState("user");
 
    const { name, guid, token } = user;
 
    return (
        <>
            <b>Welcome Page: </b>
            {name} {guid}
            <button onClick={() => setUser({ token: Math.random() })}>Change</button>
            {token}
        </>
    );
};

<div ng-controller="helloController">
    <react-state name="user"></react-state>
    <react-component name="WelcomePage"></react-component>
</div>

angular.module('app', ['react-state'])
.controller('helloController', function($scope) {
 
  $scope.user = {
    name: "Mike",
    guid: 123455,
    token: Math.random()
  }
 
  setInterval(function() {
    $scope.user.token = Math.random()
      // Notify subscribers.
    $scope.$apply()
  }, 3000)
 
})
//=> "!"

React shared State Component Angular1 Factory

<div ng-controller="helloController">
    <div id="welcomePage"></div>
</div>

angular.module('app', ['react-state'])
.controller('helloController', function($scope, reactState) {
 
  $scope.user = {
    name: "Joe",
    guid: 123455,
    token: Math.random()
  }
 
  reactState('user', $scope.user)
  render(<WelcomePage />, document.getElementById("welcomePage"));
 
  setInterval(function() {
    $scope.user.token = Math.random()
      // Notify subscribers.
    $scope.$apply()
  }, 3000)
 
})
//=> "!"

Api

The angular module attaches itself to angular as "react-state" and can be injected as such:

angular.module("app", ["react-state"])

It also exposes 4 objects to the global or window ngReactState

export {reactState, createReactProvider, reactComponent}

1. reactState - directive

<react-state name="ScopeNameObject" [Optional Scope name Object: props=""] [Optional Scope name update Function: updater=""]></react-state>

1. reactComponent - directive

<react-component name="ComponentName" props="Optional scope Object"></react-component>

1. createReactProvider - factory alias "reactState"

returns Updater Function = reactState(Name: String, [Optional InitialValue: Props: Object], [Optional onUpdate: Function])

Name is the name of the useSharedState provider
