What are the best practices for handling 404 errors in a Create React App?

To handle 404 errors in a Create React App, you should create a dedicated 404 component and use React Router to display it when no routes match.

Can you show me how to create a 404 component?

Sure! You can create a simple 404 component like this:

const NotFound = () => {
  return <h1>404 - Page Not Found</h1>;
};

Then, use it in your routing setup.

How do I set up routing to use this 404 component?

You can set up routing using React Router like this:

import { BrowserRouter as Router, Route, Switch } from 'react-router-dom';

<Router>
  <Switch>
    {/* Your other routes */}
    <Route component={NotFound} />
  </Switch>
</Router>

Is there a way to customize the 404 page further?

Absolutely! You can add images, links to the homepage, or even a search bar to help users find what they're looking for.
