Nesting Routes in react-router v4

Question

I've upgraded the react router to version 4 in my application. But now I'm getting the error

Warning: You should not use <Route component> and <Route children> in the same route; <Route children> will be ignored

What is wrong with this routing?

import {
    Switch,
    BrowserRouter as Router,
    Route, IndexRoute, Redirect,
    browserHistory
} from 'react-router-dom'   

render((
    <Router history={ browserHistory }>
        <Switch>
            <Route path='/' component={ Main }>
                <IndexRoute component={ Search } />
                <Route path='cars/:id' component={ Cars } />
                <Route path='vegetables/:id' component={ Vegetables } />
            </Route>
            <Redirect from='*' to='/' />
        </Switch>
    </Router>
), document.getElementById('main'))

Answer 1

Nested routes are not available from version react-router 4.x. Here is a basic example straight from react-router documentation on how to code for nesting route secnarios in v4.x.

Also have a look on this question as well Why can I not nest Route components in react-router 4.x?

Answer 2

IndexRoute and browserHistory are not available in the latest version, also nested Routes do not work with v4, Instead, you can specify Routes within the component Itself

import {
    Switch,
    BrowserRouter as Router,
    Route,  Redirect
} from 'react-router-dom'   

render((
    <Router>
        <Switch>
            <Route exact path='/' component={ Main }/>

            <Redirect from='*' to='/' />
        </Switch>
    </Router>
), document.getElementById('main'))

Then in the Main Component

render() {
     const {match} = this.props;
     return (
        <div>
           {/* other things*/}
           <Route exact path="/" component={ Search } />
           <Route path={`${match.path}cars/:id`} component={ Cars } />
         </div>
    )

}

Similarly in the cars component

you will have

render() {
     const {match} = this.props;
     return (
        <div>
           {/* other things*/}
           <Route path={`${match.path}/vegetables/:id`} component={ Vegetables } />
        </div>
    )

}
