# 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
|
||||

## How to Enable Google Sign-In (Quick Start)
|
||||
|
||||
### Step 1: Get Google Credentials (5 minutes)
|
||||
```
|
||||
1. Go to: https://console.cloud.google.com/
|
||||
2. Create new project called "estate-platform"
|
||||
3. Enable Google+ API
|
||||
4. Create OAuth 2.0 credentials (Web type)
|
||||
5. Add redirect: http://localhost:3001/auth/google/callback
|
||||
6. Copy Client ID and Client Secret
|
||||
```
|
||||
|
||||
### Step 2: Configure in Admin (2 minutes)
|
||||
```
|
||||
1. Go to: http://localhost:3001/admin/setup
|
||||
2. Scroll to "OAuth Providers (BetterAuth)" section
|
||||
3. In Google card:
|
||||
- ✓ Check "Enable Google OAuth"
|
||||
- Paste Client ID
|
||||
- Paste Client Secret
|
||||
- Click "💾 Save Settings"
|
||||
```
|
||||
|
||||
### Step 3: Test (1 minute)
|
||||
```
|
||||
1. Go to http://localhost:3001
|
||||
2. Click login button
|
||||
3. Click "🔍 Continue with Google"
|
||||
4. You'll see Google login page - it works!
|
||||
```
|
||||
|
||||
**Total Time**: ~8 minutes to have working Google OAuth

## All OAuth Providers
|
||||
|
||||
| Provider | Difficulty | Getting Started |
|
||||
|----------|-----------|-----------------|
|
||||
| 🔍 Google | ⭐⭐ Medium | [https://console.cloud.google.com/](https://console.cloud.google.com/) |
|
||||
| 🐙 GitHub | ⭐ Easy | [https://github.com/settings/developers](https://github.com/settings/developers) |
|

|

|
||||
|
||||
## 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
|
||||
```
|
||||

## Files Changed
|
||||
|
||||
**Modified**:
|
||||
- [components/auth/AuthModal.tsx](../components/auth/AuthModal.tsx) - Fixed OAuth redirect
|
||||
- [app/admin/setup/page.tsx](../app/admin/setup/page.tsx) - Added OAuth UI
|
||||
|
||||
**Created**:
|
||||

|
||||
|
||||
**Already Existed**:
|
||||
- [lib/auth.ts](../lib/auth.ts) - BetterAuth config (already using BetterAuth!)
|
||||
- [app/api/auth/[...route]/route.ts](../app/api/auth/[...route]/route.ts) - BetterAuth handler
|
||||
|
||||

|
||||
|
||||
## Key Points
|
||||
|
||||
### ✓ Using BetterAuth (NOT custom auth)
|
||||
Your app already uses BetterAuth - a professional OAuth framework
|
||||
|
||||
### ✓ Admin-Configurable
|
||||
No server restart needed. Just go to `/admin/setup` and toggle providers
|
||||
|
||||
### ✓ Production Ready
|
||||
BetterAuth is industry-standard, secure, and maintained
|
||||
|
||||
### ✓ Supports 4 Providers
|
||||
Google, GitHub, Facebook, Discord all work the same way
|
||||
|
||||
### ✓ OAuth Buttons Now Work
|
||||
Fixed the redirect issue - buttons now properly send to provider login
|
||||
|

|
||||
|
||||
## Next: Get Your First OAuth Working
|
||||
|
||||
**Easiest**: Google OAuth (15 minutes)
|
||||
|
||||
1. Go to [Google Cloud Console](https://console.cloud.google.com/)
|
||||
2. Create project, enable Google+ API
|
||||
3. Create OAuth credentials with redirect URI: `http://localhost:3001/auth/google/callback`
|
||||
4. Copy Client ID + Secret
|
||||
5. Go to `/admin/setup`, enable Google, paste credentials
|
||||
6. Test by clicking "Continue with Google" on login page
|
||||
|
||||
**Done!** Google sign-in will work.
