Using React IndexRoute in react-router v4

Question

I'm learning React myself with online tutorial.

So this is a basic example about using React Router:

<Router history={browserHistory}>
  <Route path="/" component={App}>
    <IndexRoute component={Home}/>
    <Route path="/home" component={Home}/>
    <Route path="/about" component={About}/>
    <Route path="/contact" component={Contact}/>
  </Route>
</Router>

With my App component:

class App extends React.Component {
   render() {
      return (
         <div>
            <ul>
              <li><Link to="home">Home</Link></li>
              <li><Link to="about">About</Link></li>
              <li><Link to="contact">Contact</Link></li>
           </ul>
          {this.props.children}
        </div>
     )
   }
}
export default App;

However, I have problem when using IndexRoute because it shows nothing, so I search for the module of react-router-dom v4 on npm and there is no IndexRoute inside. Instead it uses this:

<Router>
  <div>
  <ul>
    <li><Link to="/">Home</Link></li>
    <li><Link to="/about">About</Link></li>
    <li><Link to="/contact">Contact</Link></li>
  </ul>
  <hr/>
  <Route exact path="/" component={Home}/>
  <Route path="/about" component={About}/>
  <Route path="/contact" component={Contact}/>
  </div>
</Router>

So how can I render 2 component for 1 path ?

Solution 1

UPDATE react-router-4 has changed in that it no longer has children. However, with the Route component you can render anything that matches the path.

<Router>
  <div>
    <ul>
      <li><Link to="/">Home</Link></li>
      <li><Link to="/about">About</Link></li>
      <li><Link to="/contact">Contact</Link></li>
    </ul>
    <hr/>

    // All 3 components below would be rendered when in a homepage
    <Route exact path="/" component={Home}/>
    <Route exact path="/" component={About}/>
    <Route exact path="/" component={Contact}/>

    <Route path="/about" component={About}/>
    <Route path="/contact" component={Contact}/>
  </div>
</Router>

This means that if you want a wrapper, you can write it inside the component.

Solution 2

react-router & no IndexRoute any more

<Route exact path="/" component={Home}/> equal to <IndexRoute component={Home}/>

// Switch

<Route path="/about" component={About}/>
<Route path="/:user" component={User}/>
<Route component={NoMatch}/>

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

<Switch>
    <Route exact path="/" component={Home}/>
    <Route path="/about" component={About}/>
    <Route path="/:user" component={User}/>
    <Route component={NoMatch}/>
</Switch>


/* there will only ever be one child here */

<Fade>
    <Switch>
        <Route/>
        <Route/>
    </Switch>
</Fade>

<Fade>
    <Route/>
    <Route/>
</Fade>

/* there will always be two children here, one might render null though, making transitions a bit more cumbersome to work out */

so if I dont specify the path property, it will always be rendered ?

[Quoc-Hao Tran]

I tried your solution, but with that the 3 others component wouldn't be rendered.

[The questioner]

So, no need the <Route path="/" component={App}> App container component then?

[Deividas Karzinauskas]

@Thequestioner yes. You can simply add content you want or just wrap routes as you would wrap any other components.

I was hoping to use the IndexRoute and route wrappers to acquire the location.search string so I can create a context for query parameters. Now with react router v4 how do I do this?
