Using React Component in Angular 2

Question

I have a set of react components and i am trying to use them in an Angular 2 app.

Here is the Main React Component that i am trying to use

import React, {Component} from 'react';
import { createStore, applyMiddleware } from 'redux';
import { Provider } from 'react-redux';
import configureStore from './store/configureStore';
import MyCardContainer from './containers/MyCardContainer';
import './assets/style/main.css';
export default class MyCard extends Component {

    constructor(props){
        super(props);
    }

    componentWillMount(){

    }

    render(){
        if(this.props.param1 && this.props.param2) {
            return (
                <Provider store={configureStore()}>
                    <MyCardContainer param1={this.props.param1} param2={this.props.param2} key='container'/>
                </Provider>
            )
        }
        else{
            return(
                <div>
                    Invalid Params are provided for MyCard Component !!
                </div>
            )
        }
    }
}

Now in my angular project i have the following files.

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { MyCardHostComponent } from './mycardhost.component';

@NgModule({
  declarations: [
    AppComponent,
    MyCardHostComponent
  ],
  imports: [
      BrowserModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'app';
}

app.component.html

<div style="text-align:center">
  <h1>
    Welcome to React Components Usage Page
  </h1>
  <div>
    <my-card-host></my-card-host>
  </div>
  <div id="my-card"></div>
</div>

And mycardhost.component.ts

I tried both OnInit and AfterContentInit . I only had one active at a given time. Initially in the template i didn't have the div with id "my-card" (which i have in

import {Component, ViewChild,ElementRef,AfterContentInit} from '@angular/core';
import {MyCard} from './MyCard';
@Component({
  selector: 'my-card-host',
  templateUrl:"./mycardhost.component.html"
})

export class MyCardHostComponent implements OnInit, AfterContentInit{

    @ViewChild('my-card') myCard: ElementRef;

    ngOnInit(){
       // MyCard.initialize("param1val","param2val",document.getElementById("my-card"));
    }

    ngAfterContentInit(){
      MyCard.initialize("param1val","param2val",this.myCard.nativeElement);
    }
}

and the template file for the mycardhost.component.html which has the div tag with id "my-card" where the React Component will be loaded.

<div id="my-card"></div>

And when i run the app the React Store and Reducers are getting initialized. How ever i am getting the following Error: Which indicated the document.getElementById() that i am passing is not a valid DOM Element.

I tried putting break points in the Angular Components and none of them are getting executed. Not sure what i am doing wrong. Really appreciate any help.

Answer 1

Finally i am able to resolve the Issue.

All i needed to change was the way i was importing of the Component.

i had to change the below line

import MyCard from 'my-components-react';

to

import MyCard from 'my-components-react/es/MyCard';

Thanks
