Adjust the attributes of a React component using a distinct component

I am facing a challenge with my React MaterialUI AppBar component. I have set the property title to dynamically change based on the value returned by window.location.pathname. However, the issue arises when a different component triggers a page/url change.

<AppBar
title={this.renderTitle()}
/>

renderTitle() {
if (window.location.pathname === '/home'
 return 'home';
} else if (window.location.pathname === '/login'
return 'login';
}

Despite my intention for renderTitle() to execute upon any page/url change within the application, it does not run as expected.

For instance, if navigating from /home to /login, the following sequence occurs:

The current pathname is /home
User interacts with another component triggering a function, submit(), to change the page using react-router
Although renderTitle() is called at this point, window.location.pathname still reflects the previous page
The page transitions to /login after executing submit()
At this stage, window.location.pathname accurately shows /login, but it is too late as renderTitle() has already executed

Any assistance in resolving this issue would be greatly appreciated. Thank you!

To optimize, it's recommended to utilize the react-document-title library. According to the documentation:

The react-document-title library offers a clear method for defining the document.title in a single-page application. This feature is also compatible with server-side usage.

If your AppBar-rendering component is functioning as a route, you can simply extract the pathname from the props injected by react router.

<Router>
   <Route path="/" component={App}>
     <Route path="about" component={About} />
     <Route path="inbox" component={Inbox}>
       <Route path="messages/:id" component={Message} />
     </Route>
   </Route>
 </Router>

In components like App, About, Inbox, and Message, you have access to the router props and can pass them down to their children.

render() {
  return (
   <AppBar
     title={this.renderTitle(this.props.location.pathname)}
   />
  );
}

Within your function, you can utilize this parameter to fetch the correct outcome. By leveraging props, your component will automatically update when they undergo any changes.
