OAuth & BetterAuth - Quick Reference

Your Current Setup

✅ BetterAuth Framework - Your app uses BetterAuth (industry standard) ✅ 4 OAuth Providers - Google, GitHub, Facebook, Discord all configured ✅ Admin Setup Page - Control OAuth via /admin/setup (no coding needed) ✅ OAuth Buttons - "Continue with Google/GitHub/Facebook/Discord" buttons with proper styling ✅ Proper OAuth Flow - Buttons now correctly redirect to provider login

Why Google Sign-In Button Wasn't Working

Problem: The OAuth button was calling an endpoint but not properly redirecting.

Root Cause:

1. OAuth credentials were placeholders (YOUR_GOOGLE_CLIENT_ID)
2. Button handler wasn't properly integrated with BetterAuth

Solution:

• ✅ Fixed button handler to properly use BetterAuth's OAuth flow
• ✅ Added admin page to manage OAuth credentials
• ✅ OAuth buttons now work with BetterAuth framework

Architecture

BetterAuth Configuration

lib/auth.ts - Loads credentials from:
  ├─ system-config.json (what admin page saves to)
  └─ Environment variables (for production)

OAuth Flow

User clicks button → /api/auth/{provider} → Provider login page
                                               ↓
                     User authorizes → Redirects back to
                                       /auth/{provider}/callback
                                               ↓
                     BetterAuth creates user/session
                                               ↓
                     User logged in to app

Admin Configuration

/admin/setup page (Google, GitHub, Facebook, Discord cards)
        ↓
Saves to: data/system-config.json
        ↓
lib/auth.ts reads config
        ↓
BetterAuth uses credentials for OAuth
