Using React IndexRoute in react-router v4
Javascriptnode.jsReactjsReact RouterReact Router-V4Javascript Problem Overview
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 - Javascript
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 - Javascript
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 */

Solution 3 - Javascript
I don't know if this helps but these are the codes that I used.
File Structure:
src
-index.js
-app(folder)
--components(folder)
---Header.js
---Home.js
---Root.js
---User.js
src/app/index.js
import React, {Component} from "react";
import { render } from "react-dom";
import { browserHistory} from "react-router";
import { BrowserRouter as Router, Route, IndexRoute} from "react-router-dom";
import Root from "./components/Root";
import Home from "./components/Home";
import User from "./components/User";
class App extends Component {
render() {
return (
<Router history={browserHistory}>
<div>
<Root>
<Route exact path={"/"} component={Home} />
<Route path={"/user"} component={User} />
<Route path={"/home"} component={Home} />
</Root>
</div>
</Router>
)
}
}
render (<App />, window.document.getElementById("app"));
src/app/components/Root.js
import React, {Component} from "react";
import { render } from "react-dom";
import Header from "./Header";
import Home from "./Home";
class Root extends Component{
render(){
let renderData;
renderData = (
this.props.children
);
return(
<div>
<div className="container">
<div className="row">
<div className="col-xs-10 col-xs-offset-1">
<Header/>
</div>
</div>
<div className="row">
<div className="col-xs-10 col-xs-offset-1">
{renderData}
</div>
</div>
</div>
</div>
);
}
}
export default Root;
src/app/components/Home.js
import React, {Component} from "react";
class Home extends Component{
render(){
return(
<div>
<p>{this.props.isExist}</p>
<h2>Home</h2>
</div>
);
}
}
export default Home;
src/app/components/User.js
import React, {Component} from "react";
class User extends Component{
render(){
return(
<div>
<h3>The user page</h3>
<p>User ID:</p>
</div>
);
}
}
export default User;
webpack.config.js
var webpack = require("webpack");
var path = require("path");
var DIST_DIR = path.resolve(__dirname, "dist");
var SRC_DIR = path.resolve(__dirname, "src");
var config = {
entry: SRC_DIR + "/app/index.js",
output: {
path: DIST_DIR + "/app",
filename: "bundle.js",
publicPath: "/app/"
},
module:{
loaders: [
{
test: /\.js?/,
include: SRC_DIR,
loader: "babel-loader",
query:{
presets: ["react", "es2015", "stage-2"]
}
}
]
}
};
module.exports = config;

<Router history={browserHistory}>
<div>
<Root>
<Redirect from="*" to="/home"/>
<Route path="/home" component={Home}/>
<Route path={"/user"} component={User} />
<Route path={"/home"} component={Home} />
</Root>
</div>
</Router> try Please try this....

Note:-
<Route exact path="/" component={Home}/>
