How to set a base url for react-router at the app level?

问题

I have an app created with create-react-app that I want to install in a subdirectory on my website. The recommended way is to add process.env.PUBLIC_URL as the baseurl. ie:

<Route exact path={`${process.env.PUBLIC_URL}/signin`} component={SigninPage}/>

Now is there a way I can set it at the app level so I don't have to duplicate this piece of code on every Routes or Links or NavLinks?

Thanks!

You can set it as basename on your Router, here are links to the react router docs: basename in BrowserRouter and basename in HashRouter. It would look something like this:

<Router basename={process.env.PUBLIC_URL}>
</Router>
