How do I implement authentication and authorization in React Router?

To implement authentication in React Router, you can use a combination of context and protected routes. Would you like a code example?

Yes, please provide a code example for protected routes.

Sure! You can create a PrivateRoute component that checks if a user is authenticated before rendering the desired component. Here's a simple example:

import { Route, Redirect } from 'react-router-dom';

const PrivateRoute = ({ component: Component, isAuthenticated, ...rest }) => (
  <Route
    {...rest}
    render={props =>
      isAuthenticated ? (
        <Component {...props} />
      ) : (
        <Redirect to='/login' />
      )
    }
  />
);

This way, if the user is not authenticated, they will be redirected to the login page.

What about handling user login and logout?

For handling login and logout, you can create a context to manage user state. When a user logs in, update the context, and on logout, clear the user state. Would you like to see an example of that?
