react router v4 default page(not found page)
This is common purpose, directing unmatch request to notfound page.
making this with react-router v4" title="react-router v4">react-router v4 looks like previous versions and I expect this
sample works below. Links work fine but I expect NotFound component called only unknown url requested; but its always there.
import {BrowserRouter as Router,
Route,
Link
} from 'react-router-dom'
class Layout extends Component {
render() {
return (
<Router>
<div className="App">
<ul>
<li><Link to="/">Home</Link></li>
<li><Link to="/user">User</Link></li>
</ul>
<Route exact path="/" component={Home}/>
<Route path="/user" component={User}/>
<Route path="*" component={Notfound}/>
</div>
</Router>
);
}
}
its since path="*"
represent all request and notfound component always there but how can I say hide this component for valid url path?
Answer
React Router's No Match documentation covers this. You need to import the <Switch>
component, then you can remove the path
attribute altogether.
A
<Switch>
renders the first child<Route>
that matches. A<Route>
with no path always matches
This is the example that uses:
<Router> <div>
<Switch>
<Route path="/" exact component={Home}/>
<Redirect from="/old-match" to="/will-match"/>
<Route path="/will-match" component={WillMatch}/>
<Route component={NoMatch}/>
</Switch>
</div>
</Router>
So in your case, you'd simply drop the path="*"
and introduce the <Switch>
:
<Switch> <Route exact path="/" component={Home}/>
<Route path="/user" component={User}/>
<Route component={Notfound} />
</Switch>
Remember to include Switch
to your import
statement at the top.
