react-router - Cannot get information in this.props.location

Question

I have a app created from create-react-app and the prop location for all my components is always undefined..

Here is index.js

    ReactDOM.render((
<BrowserRouter >
<App/>
</BrowserRouter>
), document.getElementById('root'));
registerServiceWorker();

Here is a short version of app.js

import {BrowserRouter as Router, Route, Switch} from 'react-router-dom';
class App extends React.Component {

  constructor(props) {
    super(props);
    this.state = {
      auth: UserProfile.getAuth(),
    }

  }

  render() {
    if(this.state.auth){
      return (
        <Router>
          <Switch>
            ...
            <Route path="/editUser" render={()=><EditUser className="App" app={this}/>} />
          </Switch>
        </Router>
      );
    }

    else{
      ...
    }
  }
}

now here is editUser.jsx

class EditUser extends React.Component {
  constructor(props) {
    super(props);
...
}

componentDidMount(){
    console.log(this.props.location) //undefined
  }

render() {
return (<div>...</div>)

I keep getting undefined and I dont understand why... I use "react-router-dom": "^4.3.1" according to my package.json

Please help!

You need to pass the router props into the component since you're using the render prop of the <Route/> component.

Also, In your App component you don't need BrowserRouter as Router since you're already wrapping <App/> in index.js. I changed the import and removed the wrapping <Router/> component.

import { Route, Switch } from 'react-router-dom';

class App extends React.Component {
    ...
    render() {
        if (this.state.auth) {
            return (
                <Switch>
                    ...
                    <Route path="/editUser" render={props =>
                        <EditUser {...props} className="App" app={this}/>
                    }/>
                </Switch>
            );
        }
    }
}

I think you need to use the withRouter HOC on your EditUser Component in order to inject props like location.

See react-router getting this.props.location in child components
