# BetterAuth Integration - Complete Implementation Summary
|
|
|
|
## ✅ What's Completed
|
|
|
|
### 1. **Infrastructure Setup**
|
|
- ✅ Installed BetterAuth framework and dependencies
|
|
- ✅ Updated Prisma schema with BetterAuth tables (Account, Session, Verification)
|
|
- ✅ Preserved all custom fields (role, firstName, lastName, dob, gender, address)
|
|
- ✅ Created Prisma migration: `20260203215650_migrate_to_betterauth`
|
|
- ✅ Database fully synchronized
|
|
|
|
### 2. **Backend Configuration**
|
|
- ✅ Created BetterAuth configuration (`lib/auth.ts`)
|
|
- Email/Password auth (8-20 characters, uppercase, number requirements)
|
|
- OAuth providers: Google, GitHub, Facebook, Discord
|
|
- Configurable from system-config.ts
|
|
- Lazy-loaded singleton instance
|
|
|
|
- ✅ API Routes:
|
|
- `/api/auth/[...route]/route.ts` - Single handler for all BetterAuth endpoints
|
|
- `/auth/google/callback/route.ts` - Google OAuth callback
|
|
- `/auth/github/callback/route.ts` - GitHub OAuth callback
|
|
- `/auth/facebook/callback/route.ts` - Facebook OAuth callback
|
|
- `/auth/discord/callback/route.ts` - Discord OAuth callback
|
|
|
|
### 3. **Frontend Components**
|
|
- ✅ Refactored AuthModal (`components/auth/AuthModal.tsx`)
|
|
- Uses BetterAuth client hooks
|
|
- Email/password sign-up and sign-in
|
|
- Password strength validation (real-time feedback)
|
|
- Dynamic OAuth buttons (enabled/disabled based on config)
|
|
- Error handling with specific messages
|
|
|
|
- ✅ Auth Client (`lib/auth-client.ts`)
|
|
- BetterAuth React integration
|
|
- useSession and useAuthStatus hooks
|
|
- signUp.email, signIn.email functions
|
|
|
|
### 4. **Session Management**
|
|
- ✅ Middleware (`middleware.ts`)
|
|
- Session verification for protected routes (/account/*, /admin/*)
|
|
- User role added to request headers
|
|
- Automatic redirect for unauthenticated users
|
|
|
|
### 5. **Configuration Management**
|
|
- ✅ System Config Extended (`lib/system-config.ts`)
|
|
- oauth object with provider settings
|
|
- email configuration with fromAddress
|
|
- Loads credentials from .env or database
|
|
|
|
## 🚀 How to Use
|
|
|
|
### 1. **Generate Secure Secret**
|
|
```bash
|
|
npx @better-auth/cli secret
|
|
# Copy the output and add to .env
|
|
export BETTER_AUTH_SECRET=your-secret-here
|
|
```
|
|
|
|
### 2. **Set OAuth Credentials (Choose One)**
|
|
|
|
**Option A: Environment Variables** (.env)
|
|
```bash
|
|
# Google
|
|
GOOGLE_CLIENT_ID=your-google-client-id
|
|
GOOGLE_CLIENT_SECRET=your-google-client-secret
|
|
|
|
# GitHub
|
|
GITHUB_CLIENT_ID=your-github-client-id
|
|
GITHUB_CLIENT_SECRET=your-github-client-secret
|
|
|
|
# Facebook
|
|
FACEBOOK_CLIENT_ID=your-facebook-app-id
|
|
FACEBOOK_CLIENT_SECRET=your-facebook-app-secret
|
|
|
|
# Discord
|
|
DISCORD_CLIENT_ID=your-discord-client-id
|
|
DISCORD_CLIENT_SECRET=your-discord-client-secret
|
|
```
|
|
|
|
**Option B: Admin Setup Page** (recommended for production)
|
|
- Navigate to `/admin/setup`
|
|
- Enter OAuth credentials for each provider
|
|
- Toggle enable/disable per provider
|
|
- Settings automatically saved to database
|
|
|
|
### 3. **Test Authentication**
|
|
|
|
**Email/Password:**
|
|
```
|
|
1. Click "Sign Up" button
|
|
2. Enter: Name, Email, Password (must meet requirements)
|
|
3. Should see: "Account created! Redirecting..."
|
|
4. Redirects to /account/webinars
|
|
```
|
|
|
|
**OAuth (example: Google):**
|
|
```
|
|
1. Click "Google" button in auth modal
|
|
2. Redirects to Google login
|
|
3. After approval, redirects back to /account/webinars
|
|
4. User created in database with OAuth account linked
|
|
```
|
|
|
|
### 4. **Database Tables Created**
|
|
|
|
```prisma
|
|
// User (extended with custom fields)
|
|
- id, email, name, emailVerified, image
|
|
- role, firstName, lastName, gender, dob, address (custom fields)
|
|
|
|
// Account (OAuth accounts)
|
|
- Provider links (google, github, facebook, discord)
|
|
- Access tokens and refresh tokens
|
|
|
|
// Session (Session tokens)
|
|
- sessionToken (unique identifier)
|
|
- userId, expires
|
|
|
|
// Verification (Email verification & password reset)
|
|
- Email verification tokens
|
|
- Password reset tokens
|
|
```
|
|
|

## 🎯 Next Steps
|
|
|
|
### Immediate (Optional but Recommended)
|
|
1. **Remove old custom auth files** (no longer needed):
|
|
```bash
|
|
rm -rf lib/auth/
|
|
rm -rf app/api/auth/login/ app/api/auth/register/ app/api/auth/logout/
|
|
rm -rf app/api/auth/change-password/ app/api/auth/me/
|
|
```
|
|
|
|
2. **Update old session references** in these files:
|
|
- `app/api/admin/users/route.ts` - Auth checks
|
|
- `app/api/admin/registrations/route.ts` - Auth checks
|
|
- `app/layout.tsx` - Remove old session provider (if exists)
|
|
|
|
### Short Term
|
|
1. **Add OAuth setup page** to admin panel:
|
|
- Fields for Google, GitHub, Facebook, Discord credentials
|
|
- Toggle switches to enable/disable providers
|
|
- Save to SystemConfig via `/api/admin/setup`
|
|
|
|
2. **Test complete OAuth flow**:
|
|
- Register with email/password
|
|
- Login with Google
|
|
- Login with GitHub
|
|
- Check user creation and linking
|
|
|
|
### Long Term
|
|
1. **Add advanced features**:
|
|
- Two-factor authentication (TOTP)
|
|
- Email magic links
|
|
- Social profile data sync
|
|
- Account linking/unlinking UI
|
|
|
|
2. **Monitor and maintain**:
|
|
- Watch BetterAuth updates
|
|
- Monitor failed login attempts
|
|
- Review OAuth token expiration logs
|
|
|

## 🐛 Troubleshooting
|
|
|
|
| Problem | Solution |
|
|
|---------|----------|
|
|
| "Social provider missing clientId" | Add OAuth credentials to .env or admin setup page |
|
|
| Login redirects to "/" | Check middleware.ts - may need path adjustment |
|
|
| Session not persisting | Verify DATABASE_URL is correct and migrations ran |
|
|
| OAuth callback error | Check APP_BASE_URL matches OAuth app redirect URI |
|
|
| Email verification not working | Set SMTP credentials and verify EMAIL_FROM is set |
