Firebase Authentication Skill

Implement Firebase Google Sign-In in React by wrapping your application in a reusable AuthProvider context that uses signInWithPopup and onAuthStateChanged to persist user session state across components.

Context API manages Firebase authentication by providing a centralized AuthProvider wrapper that exposes user, loading, and error states globally, allowing any React component to access login and logout functions without prop drilling.

Yes, you can create protected routes in React by checking the user object provided by the Firebase AuthProvider context, gating page access based on the authentication status returned from onAuthStateChanged.

The best way to handle auth state persistence is using the onAuthStateChanged listener within a reusable AuthProvider, ensuring consistent user objects and loading indicators are maintained across your React application.

Call the signOut function provided by the Firebase AuthProvider context within your React component to securely end a user's session and clear the current Google Sign-In authentication state.
