Issues & Improvements: 404 Page, Google Auth, Firebase Security & Login Response

[PayalKumari10]

🚀 Hey everyone,
Here are some key issues in the project that need attention. Let’s collaborate to resolve them efficiently!

1️⃣ Setup 404 Page on Valid Routes
Currently, if a user navigates to a valid but non-existent route, there's no proper 404 page. Implementing a well-designed 404 page would improve user navigation and error handling.

💡 Suggested Fix:

Add a dedicated 404.js or 404.tsx component.
Redirect users to this page when they access an invalid route.
Consider adding a "Back to Home" button.
2️⃣ Google Authorization Not Working on Production
Users are facing issues with Google authentication not functioning properly in the production environment.

🔍 Possible Causes:

Incorrect OAuth client ID setup for production.
Redirect URI mismatch in Firebase or Google Cloud Console.
API restrictions in Google authentication settings.
💡 Suggested Fix:

Verify OAuth client credentials and allowed redirect URIs.
Check if the Firebase authentication mode is correctly set.
3️⃣ Firebase Credentials Exposed
It looks like Firebase credentials might be visible in the repository or frontend code, which poses a security risk.

🚨 Why is this a problem?

Anyone can access Firebase resources using exposed credentials.
Potential misuse, data leaks, and security vulnerabilities.
💡 Suggested Fix:

Move Firebase credentials to environment variables (.env).
Use server-side authentication to secure sensitive API keys.
Regenerate Firebase credentials if they've been exposed.
4️⃣ Login Click Not Responding
There's an issue where clicking the login button does not trigger any response or action.

🔍 Possible Causes:

The onClick handler might not be correctly linked.
API call issues or incorrect event handling.
UI feedback (like a loading state) might be missing.
💡 Suggested Fix:

Debug event handlers in the login function.
Check for API response errors in the console/network tab.
Implement a loading spinner or message for better user feedback.
