I'm creating an SPA and I'm trying to setup Routing in the application using the react-router-dom
package version 4.1.1
.
My Route Definition is below:
<BrowserRouter>
<div>
<Route exact path="/" component={Login} />
<Route path="/login" component={Login} />
<Route path="404" component={NotFound} />
<Route path="*" component={NotFound} />
</div>
</BrowserRouter>
Basically, I want to setup routing so that any request to a page for which no route is defined goes to the {NotFound}
component.
How can this be achieved?
The solution above renders both the Login
and the NotFound
component when requesting the /login
page.
Kind regards
here's an example from official tutorial, how to avoid rendering multiple routes
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>
Make use of Switch
to render the first match of the route, You need to import Switch
before using
import {Switch} from 'react-router';
<BrowserRouter>
<Switch>
<Route exact path="/" component={Login} />
<Route path="/login" component={Login} />
<Route path="404" component={NotFound} />
<Route path="*" component={NotFound} />
</Switch>
</BrowserRouter>
According to the docs
<Switch>
is unique in that it renders a route exclusively. In contrast, every<Route>
that matches the location renders inclusively.Now, if we’re at
/login
,<Switch>
will start looking for a matching<Route>
.<Route path="/login"/>
will match and<Switch>
will stop looking for matches and render<Login>
. otherwise route matches/login
with/login
and*
and renders both the routes
However, when using Switch the order of Routes matter, make sure that you are adding the prefix Routes after the other Routes. For e.g. '/home' must be after '/' in the Route order or else, you could make use of the exact
prop
<Switch>
<Route exact path="/" component={Login} />
<Route path="/home" component={Home} />
</Switch>
