React Router Pass Param for component

Question

const rootEl = document.getElementById('root');

ReactDOM.render(
    <BrowserRouter>
        <Switch>
            <Route exact path="/">
                <MasterPage />
            </Route>
            <Route exact path="/details/:id" >
                <DetailsPage />
            </Route>
        </Switch>
    </BrowserRouter>,
    rootEl
);

I am trying to access the id in the DetailPage component, but it is not available. I tried

<DetailsPage foo={this.props}/>

pass parameters to DetailsPage, but in vain.

export default class DetailsPage extends Component {
    constructor(props) {
        super(props);
    }

    render() {
        return (
            <div className="page">
            <Header />
            <div id="mainContentContainer" >

            </div>
            </div>
    );
    }
}

So, any idea on how to pass an identifier in a DetailsPage?

Answer 1

If you want to pass the details to the component inside the route, the easiest way is to use render, for example:

<Route exact path="/details/:id" render={(props) => <DetailsPage globalStore={globalStore} {...props} /> } />

You can access the details inside DetailPageusing:

this.props.match
this.props.globalStore

{...props}you must pass the original details of Route, otherwise you will get this.props.globalStoreinside DetailPage.

ID :

<Route path="/details/:id" component={DetailsPage}/>

:

export default class DetailsPage extends Component {
  render() {
    return(
      <div>
        <h2>{this.props.match.params.id}</h2>
      </div>
    )
  }
}
