Angular2 Directive For React Component

Note:

After 0.3.0 or higher, ng2-react has been changed to @ngui/react. Here are the changes;
  • Module ng2-react is changed to @ngui/react
  • Direvtive ng2-react is changed to ngui-react
  • Class name Ng2React is changed to NguiReact

With @ngui/react, we can do the following from Angular2

  • Pass read-only props to React component
  • Call a function in React component
  • Fire event in React componet
  • Set state of React componet

How Does It Work

  1. Angular renders ngui-react component with the following attributes;
  • reactComponent, A React component to render. Let's call it as MyComp.
  • reactProps, react props for the React component, MyComp.
  • reactState, the initial state to be used by MyComp
  1. ngui-react create and render React component using;
  • React.createElement()
  • React.render()

Access ReactJS properties

You can access react element and instance from Angular component.
  • reactElement: the react element from React.createElement()
  • reactInstance: the react instance from React.render()

Install

  1. install @ngui/react
     $ npm install @ngui/react --save  
    
  2. import NguiReactModule to your AppModule
  3.  import { NgModule } from '@angular/core';  
      import { FormsModule } from "@angular/forms";  
      import { BrowserModule } from '@angular/platform-browser';  
      import { AppComponent } from './app.component';  
      import { NguiReactModule } from '@ngui/react';  
      @NgModule({  
       imports: [BrowserModule, FormsModule, NguiReactModule],  
       declarations: [AppComponent],  
       bootstrap: [ AppComponent ]  
      })  
      export class AppModule { }  
    
For full example, please check out app directory to see the example of
  • app.module.ts
  • and app.component.ts

Example Usage

hello.ts

 class Hello extends React.Component {  
  render() {  
   return <div>Hello {this.props.name}</div>;  
  }  
 }  

my-app.ts

 import { Component, ViewChild } from '@angular/core';  
 import { Hello } from "./hello"; // This is a react component  
 @Component({  
  selector: 'my-app',  
  template: `  
   <ngui-react   
    [reactComponent]="Hello"  
    [reactProps]="{name:'angular2 react wrapper'}">  
   </ngui-react>
