Menu
I have two types of routes, countries and content:
etc...
When the user enters the application, I have to verify if he already chose a country, which I'm saving using localStorage.
If the user has the country already chosen, he needs to go to /industry/ranking, if don't, to /countries.
I'm receiving a warning about the route changing by code:
<Route> elements should not change from controlled to uncontrolled (or vice versa). You provided a "location" prop initially but omitted it on a subsequent render.
My code:
<Switch>
<Route exact path='/countries' component={Countries} />
{
current && (
<React.Fragment>
<Route exact path='/industry/ranking' render={() => <IndustryRanking country={current} />} />
<Route path='/industry/audience' render={() => <IndustryAudience country={current} />} />
<Route path='/website/ranking' render={() => <WebsiteRanking country={current} />} />
<Route path='/website/audience' render={() => <WebsiteAudience country={current} />} />
<Route path='/website/device' render={() => <WebsiteDevice country={current} />} />
<Route path='/website/conversion-orders' render={() => <WebsiteConversionOrders country={current} />} />
</React.Fragment>
)
}
{ !current ? <Redirect to='/countries' /> : <Redirect to='/industry/ranking' /> }
</Switch>
Is there a way to improve this using just the routes to verify my condition?
Thanks!

Firstly wrap all the content of your page inside the return function inside the . Next, create the induvial routes inside the component. For each route, we have the path and the element props, these tell the path on the address bar and the component to be rendered out respectively.
There are two ways to programmatically navigate with React Router - <Navigate /> and navigate() . You can get access to Navigate by importing it from the react-router-dom package and you can get access to navigate by using the custom useNavigate Hook.
import { Redirect } from "react-router-dom"; The easiest way to use this method is by maintaining a redirect property inside the state of the component. Whenever you want to redirect to another path, you can simply change the state to re-render the component, thus rendering the <Redirect> component.
You can simply write a custom component that renders the Routes or redirects to the country instead of conditionally rendering the Routes which is causing this warning
const CustomRoute = (props) => {
const current = localStorage.getItem('country');
if(current) {
return <Route {...props} />
}
return <Redirect to='/countries' />
}
and use it like
<Switch>
<CustomRoute exact path='/countries' component={Countries} />
<CustomRoute exact path='/industry/ranking' render={() => <IndustryRanking country={current} />} />
<CustomRoute path='/industry/audience' render={() => <IndustryAudience country={current} />} />
<CustomRoute path='/website/ranking' render={() => <WebsiteRanking country={current} />} />
<CustomRoute path='/website/audience' render={() => <WebsiteAudience country={current} />} />
<CustomRoute path='/website/device' render={() => <WebsiteDevice country={current} />} />
<CustomRoute path='/website/conversion-orders' render={() => <WebsiteConversionOrders country={current} />} />
<Redirect to='/industry/ranking' />
</Switch>
