Testing Google OAuth in Expo Go with Proxy

What Changed

I've updated useGoogleAuth.tsx to explicitly use Expo's auth proxy:

const redirectUri = AuthSession.makeRedirectUri({ useProxy: true });
// This generates: https://auth.expo.io/@suntex/Kindred

This might work in Expo Go because:

  • ✅ Uses HTTPS (Google's requirement)
  • ✅ Goes through Expo's auth proxy
  • ✅ Configured in your Google Console

Testing Steps

1. Check the Redirect URI

When you open your app, check the console logs:

🔗 Google OAuth Redirect URI: https://auth.expo.io/@suntex/Kindred

2. Verify Google Console Configuration

Go to Google Cloud Console and verify your Web Application client ID has this exact redirect URI:

https://auth.expo.io/@suntex/Kindred

Important: It must match EXACTLY (case-sensitive, no trailing slash)

3. Test in Expo Go

cd frontend
npx expo start

Then:

  1. Open app in Expo Go
  2. Tap "Continue with Google"
  3. Check if it works!

Expected Outcomes

✅ If It Works

  • Google OAuth screen opens
  • You can authenticate
  • Redirects back to your app
  • User is registered/logged in

This means: The proxy method works! You can continue using Expo Go for development.

❌ If It Still Fails

You'll see one of these errors:

Error 1: "Invalid Redirect URI"

  • The redirect URI in Google Console doesn't match
  • Double-check it's exactly: https://auth.expo.io/@suntex/Kindred

Error 2: "Authorization Error: invalid_request"

  • Google is still rejecting the flow
  • This means you MUST use a development build

Error 3: App doesn't open after auth

  • OAuth succeeded but redirect failed
  • Check your app.json scheme configuration

Why This Might Work Now

Previously, Google.useAuthRequest() might have been generating a different redirect URI. By explicitly setting:

redirectUri: AuthSession.makeRedirectUri({ useProxy: true })

We're forcing it to use Expo's HTTPS proxy, which Google should accept.

If It Still Doesn't Work

If you still get errors, it means Google is rejecting the Expo proxy for some reason. In that case, you'll need to:

  1. Build a development build (the reliable solution)

    cd frontend
eas build --platform ios --profile development

  2. Or test on web (quick alternative)

    npx expo start --web

Checking Your Google Console

Your Web Application client should have:

Client ID: 955300435674-5jut5auaic2u4k8udu6spkqf1b13uau8.apps.googleusercontent.com

Authorized JavaScript origins:

https://auth.expo.io

Authorized redirect URIs:

https://auth.expo.io/@suntex/Kindred

Next Steps

  1. ✅ Code is updated with explicit proxy redirect
  2. ✅ Verify Google Console configuration
  3. ✅ Test in Expo Go
  4. ❌ If it fails → Build development build

Good luck! Let me know if it works or if you see any errors. 🤞
