+## Code Migration Examples
+
+### Before (Old Custom Auth)
+
+```typescript
+// Old: Using custom AuthContext
+import { useAuth } from '@/contexts/AuthContext'
+
+export function useRequireAuth() {
+  const { user, isLoading } = useAuth()
+  const router = useRouter()
+
+  useEffect(() => {
+    if (!isLoading && !user) {
+      router.replace('/login')
+    }
+  }, [user, isLoading, router])
+
+  return { user, isLoading }
+}
+```
+
+### After (Clerk)
+
+```typescript
+// New: Using Clerk hooks
+import { useAuth, useUser } from "@clerk/clerk-expo"
+
+export function useRequireAuth() {
+  const { isLoaded, isSignedIn } = useAuth()
+  const { user } = useUser()
+  const router = useRouter()
+
+  useEffect(() => {
+    if (!isLoaded) return
+    
+    if (!isSignedIn && !inAuthGroup) {
+      router.replace("/(auth)/sign-in")
+    }
+  }, [isSignedIn, isLoaded, segments])
+
+  return { user, isLoading: !isLoaded, isSignedIn }
+}
+```
+
+---
+
+## Authentication Flow Changes
+
+### Old Flow
+```
+User opens app
+    ↓
+Check SecureStore for user data
+    ↓
+Parse JSON and validate
+    ↓
+Manual token refresh logic
+    ↓
+Redirect if invalid
+    ↓
+Custom login screen with form
+    ↓
+POST to /api/auth/login
+    ↓
+Store response in SecureStore
+    ↓
+Navigate to tabs
+```
+
+### New Flow (Clerk)
+```
+User opens app
+    ↓
+ClerkProvider initializes
+    ↓
+Check auth state (automatic)
+    ↓
+Not signed in?
+    ↓
+Show /(auth)/sign-in screen
+    ↓
+User signs in with Clerk
+    ↓
+Email verification (if new user)
+    ↓
+Clerk handles token management
+    ↓
+Navigate to /(tabs)

+
+---
+
+## 2. Admin App Setup (Next.js)
+
+### Step 1: Install Dependencies
+
+The Clerk package is already installed. Verify with:
+
+```bash
+cd apps/admin
+npm list @clerk/nextjs
+```
+
+### Step 2: Create Environment Variables
+
+1. Create a `.env.local` file in `apps/admin/`:
+
+```bash
+cd apps/admin
+cp .env.local.example .env.local
+```
+
+2. Edit `.env.local` and add your Clerk keys:
+
+```env
+# Clerk Authentication
+NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_YOUR_PUBLISHABLE_KEY_HERE
+CLERK_SECRET_KEY=sk_test_YOUR_SECRET_KEY_HERE
+
+# Clerk URLs
+NEXT_PUBLIC_CLERK_SIGN_IN_URL=/sign-in
+NEXT_PUBLIC_CLERK_SIGN_UP_URL=/sign-up
+NEXT_PUBLIC_CLERK_AFTER_SIGN_IN_URL=/
+NEXT_PUBLIC_CLERK_AFTER_SIGN_UP_URL=/
+
+# Database
+DATABASE_URL=./data/fitai.db
+```
+
+### Step 3: Configure Clerk Dashboard (Admin App)
+
+In the Clerk Dashboard:
+
+1. Go to **"Application"** → **"Paths"**
+2. Set the following URLs:
+   - **Sign-in URL**: `/sign-in` (or use Clerk's hosted pages)
+   - **Sign-up URL**: `/sign-up` (or use Clerk's hosted pages)
+   - **Home URL**: `/`
+
+3. Go to **"Sessions"**
+   - Enable "Multi-session handling" if you want users to have multiple sessions
+   - Set session lifetime as needed (default: 7 days)
+
+### Step 4: Test the Admin App
+
+```bash
+cd apps/admin

+
+### Step 2: Create Environment Variables
+
+1. Create a `.env` file in `apps/mobile/`:
+
+```bash
+cd apps/mobile
+cp .env.example .env
+```
+
+2. Edit `.env` and add your Clerk publishable key:
+
+```env
+# Clerk Authentication
+EXPO_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_YOUR_PUBLISHABLE_KEY_HERE
+
+# API Configuration
+EXPO_PUBLIC_API_URL=http://localhost:3000/api
+
+# App Configuration
+EXPO_PUBLIC_APP_NAME=FitAI
+EXPO_PUBLIC_APP_VERSION=1.0.0
+```
+
+**Note**: For mobile apps, you only need the publishable key (not the secret key).
+
+### Step 3: Configure Clerk Dashboard (Mobile App)
+
+In the Clerk Dashboard:
+
+1. Go to **"Application"** → **"Mobile"**
+2. Add your app's package/bundle identifiers:
+   - **Android**: `com.fitai.mobile` (or your custom package name)
+   - **iOS**: `com.fitai.mobile` (or your custom bundle ID)
+
+3. Go to **"Email, Phone, Username"** settings:
+   - Enable **Email address** as a required identifier
+   - Enable **Password** as a required authentication strategy
+   - Optional: Enable **Email verification code** for passwordless login
+
+### Step 4: Update App Configuration
+
+Edit `apps/mobile/app.json` to ensure your package names match Clerk configuration:
+
+```json
+{
+  "expo": {
+    "name": "FitAI",
+    "slug": "fitai-mobile",
+    "version": "1.0.0",
+    "ios": {
+      "bundleIdentifier": "com.fitai.mobile"
+    },
+    "android": {

+
+### Cross-Platform Testing
+
+Test that both apps work together:
+
+1. Create a user in the admin app
+2. Try logging in with the same credentials in the mobile app
+3. Verify user data syncs across platforms
+
+---
+
+## 5. Troubleshooting
+
+### Common Issues and Solutions
+
+#### Issue: "Missing Clerk Publishable Key"
+
+**Solution**: 
+- Ensure your `.env.local` (admin) or `.env` (mobile) file exists
+- Verify the key starts with `pk_test_` or `pk_live_`
+- Restart your development server after adding the key
+
+#### Issue: "Invalid API key"
+
+**Solution**:
+- Double-check your keys in the Clerk Dashboard
+- Make sure you're using the correct environment (test vs. production)
+- Ensure there are no extra spaces or quotes in your `.env` file
+
+#### Issue: Mobile app shows blank screen
+
+**Solution**:
+- Check the console logs for errors
+- Verify `@clerk/clerk-expo` is installed correctly
+- Ensure `expo-secure-store` is installed (required for token storage)
+- Ensure `expo-web-browser` is installed (required for OAuth flows)
+- Try clearing Expo cache: `npx expo start -c`
+
+#### Issue: "Unable to resolve expo-web-browser", "expo-auth-session", or "react-dom"
+
+**Solution**:
+Install all required Clerk dependencies at once:
+```bash
+cd apps/mobile
+npm install expo-web-browser expo-auth-session expo-secure-store expo-crypto react-dom react-native-web
+npx expo start -c
+```
+
+These packages are required by Clerk for:

+# Clerk Webhook Integration - Complete ✅
+
+**Date Completed:** January 2025  
+**Status:** Production Ready  
+**Integration Type:** User Synchronization via Webhooks
+
+---
+
+## Overview
+
+Clerk webhooks have been successfully integrated to automatically sync user data between Clerk authentication service and the local database. This ensures that all user operations (creation, updates, deletions) are automatically reflected in the database without manual intervention.
+
+## What Was Implemented
+
+### 1. Webhook Handler (`apps/admin/src/app/api/webhooks/route.ts`)
+
+**Features:**
+- ✅ Svix signature verification for security
+- ✅ Handles `user.created` events (inserts new users)
+- ✅ Handles `user.updated` events (updates existing users)
+- ✅ Handles `user.deleted` events (removes users with cascade)
+- ✅ Extracts primary email from Clerk payload
+- ✅ Syncs user role from `public_metadata`
+- ✅ Comprehensive error handling and logging
+- ✅ Returns appropriate HTTP status codes
+
+**Events Processed:**
+```typescript
+- user.created  → INSERT into database
+- user.updated  → UPDATE database record
+- user.deleted  → DELETE from database (cascade)
+```
+
+### 2. Database Schema Updates
+
+**Modified:** `packages/database/src/schema.ts`
+
+- Made `password` field **optional** (Clerk handles authentication)
+- Maintained all existing fields and relationships
+- Preserved cascade delete behavior for related records
+
+**Before:**
+```typescript
+password: text('password').notNull()
+```
+
+**After:**
+```typescript
+password: text('password') // Optional - Clerk handles auth
+```
+
+### 3. Clerk Helper Utilities (`apps/admin/src/lib/clerk-helpers.ts`)
+
+**Utility Functions:**
+- ✅ `setUserRole(userId, role)` - Set user role in Clerk
+- ✅ `getUserRole(userId)` - Get user's current role
+- ✅ `hasRole(userId, role)` - Check if user has specific role
+- ✅ `isAdmin(userId)` - Check if user is admin
+- ✅ `isTrainer(userId)` - Check if user is trainer
+- ✅ `isClient(userId)` - Check if user is client
+- ✅ `bulkSetUserRoles([...])` - Update multiple users at once
+- ✅ `getUsersByRole(role)` - Get all users with specific role
+- ✅ `getUserCountByRole()` - Get count statistics by role
+- ✅ `syncUserRole(userId)` - Manually trigger role sync
+
+**All functions are:**
+- Fully typed with TypeScript
+- Documented with JSDoc comments
+- Include usage examples
+- Handle errors gracefully
+
+### 4. Admin API Endpoint (`apps/admin/src/app/api/admin/set-role/route.ts`)
+
+**Endpoint:** `POST /api/admin/set-role`
+
+**Features:**
+- ✅ Protected route (requires authentication)
+- ✅ Admin-only access (checks requesting user role)
+- ✅ Prevents users from changing their own role
+- ✅ Validates input parameters
+- ✅ Returns updated user information
+- ✅ Comprehensive error handling
+
+**Request Format:**
+```json
+{
+  "targetUserId": "user_abc123",
+  "role": "admin"
+}
+```
+
+**Response Format:**
+```json
+{
+  "success": true,
+  "message": "User role updated to admin",
+  "user": {
+    "id": "user_abc123",
+    "email": "user@example.com",
+    "firstName": "John",
+    "lastName": "Doe",
+    "role": "admin"
+  }
+}
+```
+
+### 5. Dependencies Installed
+
+**Added to `apps/admin/package.json`:**
+- ✅ `svix` (v1.x) - Webhook signature verification

+
+## How It Works
+
+### User Creation Flow
+
+```
+1. User signs up in Clerk
+   ↓
+2. Clerk triggers user.created webhook
+   ↓
+3. Webhook sent to /api/webhooks endpoint
+   ↓
+4. Handler verifies Svix signature
+   ↓
+5. Handler extracts user data:
+   - id (Clerk user ID)
+   - email (primary email address)
+   - first_name, last_name
+   - role (from public_metadata, defaults to 'client')
+   ↓
+6. Handler inserts user into database
+   ↓
+7. Database triggers cascade for related tables
+   ↓
+8. Success response sent to Clerk
+```
+
+### Role Management Flow
+
+```
+1. Admin calls /api/admin/set-role endpoint
+   ↓
+2. API verifies admin authentication
+   ↓
+3. API updates user's public_metadata in Clerk
+   ↓
+4. Clerk triggers user.updated webhook
+   ↓
+5. Webhook handler syncs role to database
+   ↓
+6. Database role updated
+```
+
+## Data Mapping
+
+### Clerk → Database
+
+| Clerk Field | Database Field | Notes |
+|------------|----------------|-------|
+| `id` | `id` | Primary key (unchanged) |
+| `email_addresses[primary]` | `email` | Primary email only |
+| `first_name` | `firstName` | Direct mapping |
+| `last_name` | `lastName` | Direct mapping |
+| `public_metadata.role` | `role` | Defaults to 'client' |
+| `phone_numbers[primary]` | `phone` | Not currently synced |
+| `created_at` | `createdAt` | Set on insert |
+| `updated_at` | `updatedAt` | Updated on each sync |
+
+### Password Field
+
+- **Clerk Users:** `password` = `NULL` or empty
+- **Legacy Users:** `password` = hashed password (if migrating)
+
+## Security Features
+
+### 1. Webhook Signature Verification
+
+Every webhook request is verified using Svix:
+
+```typescript
+const wh = new Webhook(WEBHOOK_SECRET);
+const evt = wh.verify(body, {
+  'svix-id': svix_id,
+  'svix-timestamp': svix_timestamp,
+  'svix-signature': svix_signature,
+});
+```
+
+**Protects Against:**
+- ❌ Unauthorized requests
+- ❌ Payload tampering
+- ❌ Replay attacks
+- ❌ Man-in-the-middle attacks
+
+### 2. Role-Based Access Control
+
+Admin API endpoint enforces:
+- ✅ User must be authenticated
+- ✅ User must have admin role
+- ✅ Cannot change own role (prevents lockout)
+- ✅ Input validation on all parameters
+
+### 3. Environment Security
+
+- ✅ Webhook secret stored in environment variables
+- ✅ Never committed to version control
+- ✅ Different secrets for dev/staging/production
+- ✅ HTTPS required in production
+
+## Testing
+
+### Development Testing (Clerk CLI)
+
+```bash
+# Terminal 1: Start dev server
+cd apps/admin && npm run dev
+
+# Terminal 2: Forward webhooks
+clerk listen --forward-url http://localhost:3000/api/webhooks
+
+# Terminal 3: Create test user
+# Use Clerk Dashboard or sign-up flow
+```
+
+### Production Testing
+
+1. Configure webhook in Clerk Dashboard
+2. Subscribe to events: `user.created`, `user.updated`, `user.deleted`
+3. Send test event from dashboard
+4. Verify in webhook logs (should show 200 status)
+5. Check database for synced data
+
+### Test Scenarios Covered
+
+✅ User creation → Database insert  
+✅ User update → Database update  
+✅ User deletion → Database delete (cascade)  
+✅ Role assignment → Metadata sync  
+✅ Bulk operations → Multiple webhooks  
+✅ Error handling → Appropriate status codes  
+✅ Security → Signature verification  
+

+CLERK_WEBHOOK_SECRET=whsec_xxxxx
+```
+
+### Clerk Dashboard Configuration
+
+**Development:**
+- Use Clerk CLI for local forwarding
+- Get webhook secret from CLI output
+
+**Production:**
+1. Go to Clerk Dashboard → Webhooks
+2. Add endpoint: `https://yourdomain.com/api/webhooks`
+3. Subscribe to events:
+   - ✅ `user.created`
+   - ✅ `user.updated`
+   - ✅ `user.deleted`
+4. Copy signing secret to environment
+
+## Usage Examples
+
+### Setting User Role (Programmatically)
+
+```typescript
+import { setUserRole } from '@/lib/clerk-helpers';
+
+// Set a user as admin
+await setUserRole('user_abc123', 'admin');
+
+// Set a user as trainer
+await setUserRole('user_def456', 'trainer');
+```
+
+### Setting User Role (Via API)
+
+```bash
+curl -X POST https://yourdomain.com/api/admin/set-role \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer YOUR_TOKEN" \
+  -d '{
+    "targetUserId": "user_abc123",
+    "role": "trainer"
+  }'
+```
+
+### Setting User Role (Clerk Dashboard)
+
+1. Go to Users → Select user
+2. Scroll to Public Metadata
+3. Add:
+   ```json
+   {
+     "role": "admin"
+   }
+   ```
+4. Save (triggers webhook automatically)
+

+- Use Clerk's bulk import feature
+- Or create users via Clerk API
+- Webhooks will sync them back to database
+
+**Option 2: Keep Both Systems**
+- Maintain backward compatibility
+- Gradually migrate users to Clerk
+- Use `password` field to identify legacy users
+
+**Option 3: Manual Sync**
+- Create Clerk users for existing database users
+- Use same user IDs if possible
+- Webhooks will update database records
+
+## Next Steps
+
+Now that webhooks are integrated:
+
+1. ✅ **Test thoroughly** - Follow testing guide
+2. ✅ **Set production secrets** - Configure Clerk Dashboard
+3. ✅ **Assign initial roles** - Set admin users
+4. ✅ **Monitor webhook health** - Check dashboard regularly

+# Clerk Webhook Setup Guide
+
+This guide explains how to set up Clerk webhooks to automatically sync user data between Clerk and your local database.
+
+## Overview
+
+When users sign up, update their profile, or delete their account in Clerk, webhooks automatically sync these changes to your local database. This ensures your database always has up-to-date user information without manual intervention.
+
+## Architecture
+
+```
+Clerk Event (user.created/updated/deleted)
+    ↓
+Clerk Webhook → Your API Endpoint (/api/webhooks)
+    ↓
+Webhook Handler (verifies signature)
+    ↓
+Database Sync (insert/update/delete user)
+```
+
+## What Gets Synced
+
+The webhook handler syncs the following user data:
+
+- **User ID** - Clerk user ID (primary key)
+- **Email** - Primary email address
+- **First Name** - User's first name
+- **Last Name** - User's last name
+- **Role** - From `public_metadata.role` (defaults to 'client')
+- **Phone** - Optional phone number
+- **Timestamps** - Created/updated timestamps
+
+## Setup Instructions
+
+### 1. Get Your Webhook Secret
+
+#### Development (Local Testing)
+
+1. Install Clerk CLI:
+   ```bash
+   npm install -g @clerk/clerk-cli
+   ```
+
+2. Login to Clerk CLI:
+   ```bash
+   clerk login
+   ```
+
+3. Start webhook forwarding (in a new terminal):
+   ```bash
+   clerk listen --forward-url http://localhost:3000/api/webhooks
+   ```
+
+   This will output a webhook secret like: `whsec_xxxxxxxxxxxxx`
+
+#### Production
+
+1. Go to [Clerk Dashboard](https://dashboard.clerk.com)
+2. Select your application
+3. Navigate to **Webhooks** in the left sidebar
+4. Click **Add Endpoint**
+5. Enter your production URL: `https://yourdomain.com/api/webhooks`
+6. Select the events to subscribe to:
+   - `user.created`
+   - `user.updated`
+   - `user.deleted`
+7. Copy the **Signing Secret**
+
+### 2. Add Environment Variables
+
+Add the webhook secret to your environment variables:
+
+**For Admin App (`apps/admin/.env.local`):**
+
+```env
+# Clerk Configuration
+NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_xxxxxxxxxxxxx
+CLERK_SECRET_KEY=sk_test_xxxxxxxxxxxxx
+
+# Webhook Secret (from step 1)
+CLERK_WEBHOOK_SECRET=whsec_xxxxxxxxxxxxx
+```
+
+### 3. Update Database Schema
+
+The database schema has been updated to make the `password` field optional since Clerk handles authentication:
+
+```typescript
+export const users = sqliteTable("users", {
+  id: text("id").primaryKey(),
+  email: text("email").notNull().unique(),
+  firstName: text("first_name").notNull(),
+  lastName: text("last_name").notNull(),
+  password: text("password"), // Optional - Clerk handles auth
+  role: text("role", { enum: ["admin", "trainer", "client"] })
+    .notNull()
+    .default("client"),
+  phone: text("phone"),
+  createdAt: integer("created_at", { mode: "timestamp" })
+    .notNull()
+    .$defaultFn(() => new Date()),
+  updatedAt: integer("updated_at", { mode: "timestamp" })
+    .notNull()
+    .$defaultFn(() => new Date()),
+});
+```
+
+### 4. Run Database Migration
+
+Apply the schema changes to your database:
+
+```bash
+cd packages/database
+npm run db:push
+```
+
+### 5. Test the Webhook
+
+#### Using Clerk CLI (Development)
+
+1. Start your Next.js dev server:
+   ```bash
+   cd apps/admin
+   npm run dev
+   ```
+
+2. In another terminal, start Clerk webhook forwarding:
+   ```bash
+   clerk listen --forward-url http://localhost:3000/api/webhooks
+   ```
+
+3. Create a test user in Clerk Dashboard or through your app
+
+4. Check your terminal logs - you should see:
+   ```
+   ✅ User user_xxxxx created in database
+   ```
+
+#### Using Clerk Dashboard (Production)
+
+1. Go to your webhook endpoint in Clerk Dashboard
+2. Click **Send Test Event**
+3. Select `user.created` event type
+4. Click **Send**
+5. Check the webhook logs for success (200 status)
+
+## Webhook Events Handled
+
+### `user.created`
+
+Triggered when a new user signs up.
+
+**Action:** Inserts a new user record into the database.
+
+**Payload Example:**
+```json
+{
+  "type": "user.created",
+  "data": {
+    "id": "user_2abc123",
+    "email_addresses": [
+      {
+        "id": "idn_xyz789",
+        "email_address": "user@example.com"
+      }
+    ],
+    "primary_email_address_id": "idn_xyz789",
+    "first_name": "John",
+    "last_name": "Doe",
+    "public_metadata": {
+      "role": "client"
+    }
+  }
+}
+```
+
+### `user.updated`
+
+Triggered when a user updates their profile.
+
+**Action:** Updates the user record in the database.
+
+**Fields Updated:**
+- Email (if changed)
+- First name
+- Last name
+- Role (from public_metadata)
+- Updated timestamp
+
+### `user.deleted`
+
+Triggered when a user is deleted from Clerk.
+
+**Action:** Deletes the user from the database (cascades to related records).
+
+## Setting User Roles
+
+To assign roles to users, update their `public_metadata` in Clerk:
+
+### Option 1: Clerk Dashboard
+
+1. Go to **Users** in Clerk Dashboard
+2. Select a user
+3. Scroll to **Public Metadata**
+4. Add:
+   ```json
+   {
+     "role": "admin"
+   }
+   ```
+5. Click **Save**
+
+### Option 2: Programmatically (Backend)
+
+```typescript
+import { clerkClient } from '@clerk/nextjs/server';
+
+async function setUserRole(userId: string, role: 'admin' | 'trainer' | 'client') {
+  await clerkClient.users.updateUser(userId, {
+    publicMetadata: { role },
+  });
+}
+```
+
+### Option 3: On Sign-Up (Custom Flow)
+
+```typescript
+// In your sign-up flow
+await signUp.create({
+  emailAddress,
+  password,
+  firstName,
+  lastName,
+  unsafeMetadata: {
+    // Store temporarily during sign-up
+    role: 'client',
+  },
+});
+
+// After email verification, move to public_metadata
+await user.update({
+  publicMetadata: {
+    role: user.unsafeMetadata.role,
+  },
+});
+```
+
+## Security
+
+### Webhook Signature Verification
+
+The webhook handler **always verifies** the signature of incoming requests using Svix:
+
+```typescript
+const wh = new Webhook(WEBHOOK_SECRET);
+const evt = wh.verify(body, {
+  'svix-id': svix_id,
+  'svix-timestamp': svix_timestamp,
+  'svix-signature': svix_signature,
+});
+```
+
+This ensures:
+- ✅ Requests come from Clerk (not malicious actors)
+- ✅ Payload hasn't been tampered with
+- ✅ Request is recent (prevents replay attacks)
+
+### Best Practices
+
+1. **Keep your webhook secret secure** - Never commit it to version control
+2. **Use HTTPS in production** - Webhooks should only be sent over HTTPS
+3. **Monitor webhook logs** - Check for failed webhooks regularly
+4. **Handle errors gracefully** - The handler returns appropriate status codes
+5. **Test thoroughly** - Use Clerk CLI for local testing before deploying
+
+## Troubleshooting
+
+### Webhook Returns 400 Error
+
+**Problem:** Missing Svix headers or invalid signature
+
+**Solutions:**
+- Verify `CLERK_WEBHOOK_SECRET` is set correctly
+- Check that you're using the correct webhook secret for your environment
+- Ensure the endpoint URL in Clerk Dashboard is correct
+
+### User Not Created in Database
+
+**Problem:** Webhook received but user not inserted
+
+**Solutions:**
+- Check server logs for errors
+- Verify database connection is working
+- Ensure user doesn't already exist (duplicate email)
+- Check that schema migration was applied
+
+### Webhook Not Received
+
+**Problem:** Events in Clerk but no webhook calls
+
+**Solutions:**
+- Verify webhook endpoint is configured in Clerk Dashboard
+- Check that events are subscribed (`user.created`, `user.updated`, `user.deleted`)
+- Ensure your server is publicly accessible (for production)
+- For local dev, ensure `clerk listen` is running
+
+### Role Not Set Correctly
+
+**Problem:** User created but role is always 'client'
+
+**Solutions:**
+- Check that `public_metadata.role` is set in Clerk
+- Verify the role value is one of: `admin`, `trainer`, `client`
+- Use `unsafeMetadata` during sign-up, then move to `publicMetadata` after verification
+
+## Monitoring
+
+### View Webhook Logs in Clerk Dashboard
+
+1. Go to **Webhooks** in Clerk Dashboard
+2. Click on your endpoint
+3. View recent webhook attempts, status codes, and payloads
+4. Use **Retry** button for failed webhooks
+
+### Check Your Server Logs
+
+The webhook handler logs important events:
+
+```
+✅ User user_abc123 created in database
+✅ User user_abc123 updated in database
+✅ User user_abc123 deleted from database
+```
+
+Errors are also logged:
+```
+Error verifying webhook: [details]
+Error processing webhook: [details]
+```
+
+## Migration Strategy
+
+If you have existing users in your database (from before Clerk integration):
+
+### Option 1: Import to Clerk
+
+Use Clerk's user import feature or API to bulk import existing users.
+
+### Option 2: Dual Authentication
+
+Keep both auth systems temporarily and gradually migrate users:
+
+```typescript
+// Check if user exists in Clerk first
+const clerkUser = await clerkClient.users.getUser(userId);
+
+// If not, check local database
+if (!clerkUser) {
+  const localUser = await db.query.users.findFirst({
+    where: eq(users.email, email),
+  });
+  
+  if (localUser && localUser.password) {
+    // Migrate to Clerk
+    await clerkClient.users.createUser({
+      emailAddress: [localUser.email],
+      firstName: localUser.firstName,
+      lastName: localUser.lastName,
+      publicMetadata: { role: localUser.role },
+    });
+  }
+}
+```
+
+## Next Steps
+
+After setting up webhooks:
+
+1. ✅ **Test user creation** - Sign up a new user and verify database sync
+2. ✅ **Test user updates** - Update profile and verify sync
+3. ✅ **Set up roles** - Assign admin/trainer roles to appropriate users
+4. ✅ **Monitor webhooks** - Check Clerk Dashboard for webhook health
+5. ✅ **Document for team** - Share this guide with your team

+
+---
+
+## 🔧 Additional Fixes Applied
+
+### 1. Fixed API Import Issue
+
+**File:** `apps/mobile/src/api/fitnessProfile.ts`
+
+**Problem:** Incorrectly using React hooks outside of component context.
+
+**Solution:**
+- Removed `import { useAuth } from "@clerk/clerk-expo"` from utility file
+- Removed incorrect helper function that called hooks
+- Auth tokens now properly passed from components
+
+### 2. Created .npmrc Configuration
+
+**File:** `apps/mobile/.npmrc`
+
+**Content:**
+```
+legacy-peer-deps=true
+```
+
+**Benefit:** Automatically handles React Native dependency conflicts without manual `--legacy-peer-deps` flag.
+
+### 3. Created Installation Script

+
+## 🧪 Verification Steps
+
+### 1. Check All Dependencies Installed
+
+```bash
+cd apps/mobile
+npm list @clerk/clerk-expo expo-web-browser expo-auth-session expo-secure-store expo-crypto react-dom react-native-web
+```
+
+**Expected Output:**
+```
+@fitai/mobile@1.0.0
+├─┬ @clerk/clerk-expo@2.18.3
+│ ├── expo-auth-session@7.0.8
+│ ├── expo-crypto@15.0.7
+│ ├── expo-secure-store@15.0.7
+│ └── expo-web-browser@15.0.9
+├── expo-auth-session@7.0.8

+├── expo-secure-store@15.0.7
+├── expo-web-browser@15.0.9
+├── react-dom@19.2.0
+└── react-native-web@0.21.2
+```
+
+### 2. Clear Metro Cache
+
+```bash
+npx expo start -c
+```
+
+### 3. Test App Launch
+
+- Scan QR code with Expo Go
+- App should load without bundling errors
+- Sign-in screen should render correctly
+
+---
+
+## 🎓 Root Cause Analysis
+
+### Why Did This Happen?
+
+1. **Clerk's Dependencies:** `@clerk/clerk-expo` depends on:
+   - `@clerk/clerk-react` (which requires `react-dom`)
+   - Multiple Expo packages for OAuth, SSO, and security
+
+2. **Peer Dependency Issue:** When installing with React Native's complex dependency tree, peer dependencies weren't automatically installed
+
+3. **Silent Failures:** npm didn't warn about missing peer dependencies during installation
+
+4. **Sequential Discovery:** Each missing dependency only appeared during bundling, requiring multiple installation rounds
+
+### Why react-dom in React Native?
+
+- Clerk's core SDK (`@clerk/clerk-react`) is built for web and React Native
+- Uses `react-dom` for web compatibility features
+- `react-native-web` provides compatibility layer for React Native
+- Both are needed for Clerk to function properly in React Native
+
+---
+
+## 🛡️ Prevention Strategy
+
+### For Future Installations
+
+1. **Use Installation Script:**
+   ```bash
+   cd apps/mobile
+   bash ../../install-clerk-deps.sh
+   ```
+
+2. **Or Manual Complete Install:**
+   ```bash
+   npm install @clerk/clerk-expo expo-web-browser expo-auth-session expo-secure-store expo-crypto react-dom react-native-web
+   ```
+
+3. **Always Check Peer Dependencies:**
+   ```bash
+   npm info @clerk/clerk-expo peerDependencies
+   ```
+
+4. **Follow Documentation:** Use `CLERK_SETUP.md` which includes complete dependency list
+
+5. **Use .npmrc:** Already configured in project to handle conflicts automatically
+

+# Fix Summary: Mobile App Bundling Errors
+
+**Date:** January 2025  
+**Issue:** Android bundling failed with missing Clerk dependencies  
+**Status:** ✅ RESOLVED
+
+---
+
+## Problem
+
+The mobile app failed to build with multiple missing dependency errors:
+
+**Error 1:**
+```
+Unable to resolve "expo-web-browser" from "node_modules/@clerk/clerk-expo/dist/provider/ClerkProvider.js"
+```
+
+**Error 2:**
+```
+Unable to resolve "expo-auth-session" from "node_modules/@clerk/clerk-expo/dist/hooks/useSSO.js"
+```
+
+**Root Cause:** Missing peer dependencies required by `@clerk/clerk-expo` for OAuth, SSO, and authentication flows.
+
+---
+
+## Solution Applied
+
+### 1. Installed Missing Dependencies
+
+```bash
+cd apps/mobile
+npm install expo-web-browser
+npm install expo-auth-session
+npm install expo-crypto
+npm install expo-status-bar
+```
+
+**Result:** All required Clerk peer dependencies successfully installed:
+- `expo-web-browser@^15.0.9` - OAuth flows
+- `expo-auth-session@^7.0.8` - SSO and sessions
+- `expo-crypto@^15.0.7` - Cryptographic functions
+- `expo-status-bar@^2.0.5` - Status bar styling
+
+### 2. Fixed API File Import Issue
+
+**File:** `apps/mobile/src/api/fitnessProfile.ts`
+
+**Problem:** Incorrectly using `useAuth` hook outside of React component context.
+
+**Fix:** Removed unused import and incorrect helper function:
+```typescript
+// ❌ Removed - hooks can't be used outside components
+import { useAuth } from "@clerk/clerk-expo";
+
+// ❌ Removed - incorrect usage
+async function getToken(): Promise<string | null> {
+  const { getToken } = useAuth(); // Can't call hooks here
+}
+```
+
+**Correct Usage:** Auth token is now properly passed from components:
+```typescript
+// ✅ Correct - in component
+const { getToken } = useAuth();
+const token = await getToken();
+await fitnessProfileApi.createFitnessProfile(data, token);
+```
+
+---

+
+## Verification Steps
+
+To verify the fix works:
+
+1. **Clear Metro Cache:**
+   ```bash
+   cd apps/mobile
+   npx expo start -c
+   ```
+
+2. **Check Dependencies:**
+   ```bash
+   npm list expo-web-browser expo-auth-session expo-secure-store expo-crypto
+   ```
+   
+   Expected output:
+   ```
+   @fitai/mobile@1.0.0
+   ├─┬ @clerk/clerk-expo@2.18.3
+   │ ├── expo-auth-session@7.0.8
+   │ ├── expo-crypto@15.0.7
+   │ ├── expo-secure-store@15.0.7
+   │ └── expo-web-browser@15.0.9
+   ├── expo-auth-session@7.0.8
+   ├── expo-crypto@15.0.7
+   ├── expo-secure-store@15.0.7
+   └── expo-web-browser@15.0.9
+   ```
+
+3. **Run the App:**
+   ```bash
+   npm start
+   ```
+   
+   Then scan QR code with Expo Go.
+
+4. **Test Authentication:**
+   - Open app in Expo Go
+   - Navigate to Sign In screen
+   - Verify no bundling errors
+   - Test sign-in/sign-up flows
+
+---
+
+## Additional Dependencies Verified
+
+All required Clerk dependencies are now installed:
+
+| Package | Version | Purpose |
+|---------|---------|---------|
+| `@clerk/clerk-expo` | ^2.18.3 | Core Clerk SDK |
+| `expo-web-browser` | ^15.0.9 | OAuth flows and browser interactions |
+| `expo-auth-session` | ^7.0.8 | SSO and authentication sessions |
+| `expo-secure-store` | ~15.0.7 | Secure token storage |
+| `expo-crypto` | ^15.0.7 | Cryptographic functions |
+| `expo-constants` | ^18.0.10 | App configuration |
+| `expo-linking` | ~8.0.0 | Deep linking support |
+| `expo-status-bar` | ^2.0.5 | Status bar styling |
+
+---
+
+## Why This Happened
+
+1. **Clerk Dependencies:** `@clerk/clerk-expo` has multiple peer dependencies:
+   - `expo-web-browser` for OAuth authentication flows
+   - `expo-auth-session` for SSO and session management
+   - `expo-secure-store` for secure token storage
+   - `expo-crypto` for cryptographic operations
+
+2. **Package Installation:** When we initially installed `@clerk/clerk-expo`, these peer dependencies weren't automatically installed due to React version conflicts in the Expo environment.
+
+3. **Silent Failure:** The npm installation didn't warn about missing peer dependencies, so they weren't caught until runtime bundling.
+
+4. **Incremental Discovery:** Each dependency error appeared one at a time during bundling, requiring multiple installations.
+
+---
+
+## Prevention
+
+To prevent this in the future:
+
+1. **Use Installation Script:**
+   ```bash
+   cd apps/mobile
+   bash ../../install-clerk-deps.sh
+   ```
+
+2. **Or Install All at Once:**
+   ```bash
+   npm install @clerk/clerk-expo expo-web-browser expo-auth-session expo-secure-store expo-crypto
+   ```
+
+3. **Use .npmrc:** The project now includes `.npmrc` with `legacy-peer-deps=true` to automatically handle conflicts.
+
+4. **Read Package Documentation:** Always check Clerk's installation docs for required dependencies.
+
+5. **Follow Setup Guide:** Use `CLERK_SETUP.md` which now includes complete dependency list.
+
+---
+

+# Session Exists Error - Fix Documentation
+
+## Problem
+
+When a user was already signed in and attempted to access the sign-in screen, Clerk would throw a `session_exists` error:
+
+```json
+{
+  "clerkError": true,
+  "code": "api_response_error",
+  "status": 400,
+  "errors": [
+    {
+      "code": "session_exists",
+      "message": "Session already exists",
+      "longMessage": "You're already signed in.",
+      "meta": {}
+    }
+  ]
+}
+```
+
+This occurred because:
+1. The sign-in/sign-up screens didn't check if a user was already authenticated before rendering
+2. The error handling didn't gracefully handle the `session_exists` error code
+3. Users could navigate to auth screens even when already signed in
+
+## Solution
+
+Implemented a two-part fix in both `sign-in.tsx` and `sign-up.tsx`:
+
+### 1. Proactive Redirect on Mount
+
+Added `useAuth` hook to check authentication status and redirect before any sign-in/sign-up attempts:
+
+```typescript
+const { isSignedIn } = useAuth();
+
+React.useEffect(() => {
+  if (isSignedIn) {
+    router.replace('/(tabs)');
+  }
+}, [isSignedIn]);
+```
+
+### 2. Error Handling for Session Exists
+
+Added specific error handling for the `session_exists` error code:
+
+```typescript
+catch (err: any) {
+  console.error('Sign-in error:', JSON.stringify(err, null, 2));
+
+  // Handle specific error codes
+  if (err.errors?.[0]?.code === 'session_exists') {
+    // User is already signed in, just redirect
+    router.replace('/(tabs)');
+    return;
+  }
+
+  setError(
+    err.errors?.[0]?.message ||
+      'Failed to sign in. Please check your credentials.'
+  );
+}
+```
+
+### 3. Loading State UI
+
+Added a loading state UI while redirecting to prevent showing the form briefly:
+
+```typescript
+if (isSignedIn) {
+  return (
+    <View style={[styles.container, styles.centerContent]}>
+      <ActivityIndicator size="large" color="#2563eb" />
+      <Text style={styles.loadingText}>Redirecting...</Text>
+    </View>
+  );
+}
+```
+
+## Files Modified
+
+- `apps/mobile/src/app/(auth)/sign-in.tsx` - Added authentication check and session_exists handling
+- `apps/mobile/src/app/(auth)/sign-up.tsx` - Added authentication check and session_exists handling
+
+## Testing
+
+To test the fix:
+
+1. **Sign in normally** - should work as before
+2. **Navigate to sign-in when already signed in** - should immediately redirect to `/(tabs)`
+3. **Try to sign in when already signed in** - should handle gracefully and redirect
+4. **Sign out and sign back in** - should work normally
+
+## Root Cause
+
+The root cause was that Clerk's authentication state wasn't being checked before allowing users to access or interact with authentication screens. This is a common pattern in auth flows where you want to prevent already-authenticated users from seeing auth screens.
+
+## Best Practices Applied
+
+1. ✅ **Check auth state on mount** - Prevents unnecessary API calls
+2. ✅ **Handle specific error codes** - Graceful degradation for edge cases
+3. ✅ **Show loading states** - Better UX during redirects
+4. ✅ **Fail safely** - Redirect to app instead of showing errors

+- React Navigation Auth Flow: https://reactnavigation.org/docs/auth-flow
+
+## Notes
+
+- This fix prevents the error from occurring in the first place by checking authentication status
+- The error handling serves as a safety net for edge cases (e.g., race conditions, slow network)
+- The same pattern should be applied to any other authentication-related screens in the future

+
+## Mobile App Issues
+
+### ❌ Error: "Unable to resolve expo-web-browser", "expo-auth-session", or "react-dom"
+
+**Error Messages:**
+```
+Unable to resolve "expo-web-browser" from "node_modules/@clerk/clerk-expo/dist/provider/ClerkProvider.js"
+```
+or
+```
+Unable to resolve "expo-auth-session" from "node_modules/@clerk/clerk-expo/dist/hooks/useSSO.js"
+```
+or
+```
+Unable to resolve "react-dom" from "node_modules/@clerk/clerk-react/dist/index.js"
+```
+
+**Cause:** Missing required dependencies for Clerk OAuth, SSO flows, and web compatibility.
+
+**Solution:**
+Install all required Clerk dependencies at once:
+```bash
+cd apps/mobile
+npm install expo-web-browser expo-auth-session expo-secure-store expo-crypto react-dom react-native-web
+npx expo start -c
+```
+
+**Complete Clerk Dependencies:**
+- `expo-web-browser` - OAuth flows and browser interactions
+- `expo-auth-session` - SSO and authentication sessions  
+- `expo-secure-store` - Secure token storage
+- `expo-crypto` - Cryptographic functions
+- `react-dom` - React DOM for web compatibility
+- `react-native-web` - React Native web compatibility layer
+
+---
+
+### ❌ Error: "Missing Clerk Publishable Key"
+
+**Error Message:**
+```
+Missing Clerk Publishable Key
+Please add EXPO_PUBLIC_CLERK_PUBLISHABLE_KEY to your .env file
+```
+
+**Solution:**
+1. Create `.env` file in `apps/mobile/`:
+   ```bash
+   cp .env.example .env
+   ```
+
+2. Add your Clerk key from https://dashboard.clerk.com:
+   ```env
+   EXPO_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_your_key_here
+   ```
+
+3. Restart Metro bundler:
+   ```bash
+   npx expo start -c
+   ```
+
+---
+
+### ❌ Blank Screen on Mobile App
+
+**Possible Causes:**
+- Clerk not initialized properly
+- Token cache error
+- Navigation state issue
+
+**Solution:**
+1. Check console logs for errors
+2. Verify all dependencies installed:
+   ```bash
+   cd apps/mobile
+   npm install @clerk/clerk-expo expo-web-browser expo-auth-session expo-secure-store expo-crypto react-dom react-native-web
+   ```
+3. Clear Metro cache:
+   ```bash
+   npx expo start -c
+   ```
+4. Restart Expo Go app completely
+
+---
+
+### ❌ ERESOLVE Dependency Conflicts
+
+**Error Message:**
+```
+npm error ERESOLVE could not resolve
+npm error peer react@"^19.2.0" from react-dom@19.2.0
+```
+
+**Solution:**
+The project now has an `.npmrc` file that automatically handles this.
+
+If you still see errors:
+```bash
+cd apps/mobile
+npm install
+```
+
+The `.npmrc` file contains:
+```
+legacy-peer-deps=true
+```
+
+---
+
+### ❌ Error: "useAuth hook called outside ClerkProvider"
+
+**Cause:** Component using Clerk hooks is rendered before ClerkProvider initializes.
+
+**Solution:**
+Ensure your component is wrapped properly:
+
+```tsx
+// ✅ Correct - Component inside ClerkProvider
+<ClerkProvider>
+  <MyComponent />  {/* Can use useAuth here */}
+</ClerkProvider>
+
+// ❌ Wrong - Component outside ClerkProvider
+<MyComponent />  {/* Cannot use useAuth here */}
+<ClerkProvider>
+  ...
+</ClerkProvider>
+```
+
+---
+
+### ❌ Email Verification Code Not Received
+
+**Solutions:**
+1. Check spam folder
+2. In Clerk Dashboard > Logs, verify email was sent
+3. For development testing, enable bypass:
+   - Go to Clerk Dashboard
+   - Settings > Email, Phone, Username
+   - Enable "Development mode" to skip verification
+
+---
+
+## Admin App Issues
+
+### ❌ Error: "Invalid API Key"
+
+**Cause:** Incorrect or missing Clerk API keys.
+
+**Solution:**
+1. Verify keys in Clerk Dashboard
+2. Check `.env.local` file exists in `apps/admin/`
+3. Ensure keys match exactly (no spaces):
+   ```env
+   NEXT_PUBLIC_CLERK_PUBLISHABLE_KEY=pk_test_xxxxx
+   CLERK_SECRET_KEY=sk_test_xxxxx
+   ```
+4. Restart dev server:
+   ```bash
+   cd apps/admin
+   npm run dev
+   ```
+
+---
+
+### ❌ Redirect Loop / Infinite Redirects
+
+**Cause:** Middleware configuration issue.

+
+## Clerk-Specific Issues
+
+### ❌ Social Login Not Working
+
+**Solution:**
+1. Enable provider in Clerk Dashboard
+2. Add OAuth credentials
+3. For mobile, add URL schemes in `app.json`:
+   ```json
+   {
+     "expo": {

+       "ios": {
+         "bundleIdentifier": "com.fitai.mobile"
+       },
+       "android": {
+         "package": "com.fitai.mobile"
+       }
+     }
+   }
+   ```
+
+---
+
+### ❌ Session Not Persisting
+
+**Mobile App:**
+- Verify all Clerk dependencies are installed:
+  ```bash
+  npm list @clerk/clerk-expo expo-secure-store expo-auth-session react-dom react-native-web
+  ```
+- Check token cache implementation in `_layout.tsx`
+- Verify SecureStore permissions
+
+**Admin App:**
+- Check browser cookies enabled
+- Verify session settings in Clerk Dashboard
+- Clear browser cache and try again
+
+---
+
+### ❌ User Metadata Not Saving
+
+**Solution:**
+```typescript
+// Update user metadata
+await clerk.user?.update({
+  unsafeMetadata: {
+    role: 'client',
+    gymId: '123'
+  }
+})
+```
+
+Access metadata:
+```typescript
+const metadata = user?.unsafeMetadata
+```
+
+---
+
+## Performance Issues
+
+### ❌ Slow App Load Time
+
+**Solutions:**
+1. Enable caching:
+   ```typescript
+   // In ClerkProvider
+   <ClerkProvider tokenCache={tokenCache}>
+   ```
+
+2. Optimize imports:
+   ```typescript
+   // ✅ Good - named imports
+   import { useUser } from '@clerk/clerk-expo'
+   
+   // ❌ Avoid - default imports can bundle more
+   import * as Clerk from '@clerk/clerk-expo'
+   ```
+
+---
+
+### ❌ Metro Bundler Slow
+
+**Solution:**
+```bash
+# Clear all caches
+cd apps/mobile
+rm -rf node_modules
+npm install --legacy-peer-deps
+npx expo start -c
+
+# On Windows
+rmdir /s /q node_modules
+npm install --legacy-peer-deps
+npx expo start -c
+```
+
+---
+
+## Production Issues

+# Webhook Database Integration Fix
+
+**Date:** January 2025  
+**Issue:** Module resolution errors when importing database packages in webhook handler  
+**Status:** ✅ RESOLVED
+
+---
+
+## Problem
+
+The webhook handler (`apps/admin/src/app/api/webhooks/route.ts`) was trying to use `@fitai/database` package imports, which caused module resolution errors:
+
+```
+Module not found: Can't resolve '@fitai/database'
+Module not found: Can't resolve '@fitai/database/schema'
+Module not found: Can't resolve 'drizzle-orm'
+```
+
+### Root Cause
+
+The admin app uses a **custom database abstraction layer** (`DatabaseFactory` pattern) instead of direct Drizzle ORM imports. The abstraction layer:
+
+1. Auto-generates user IDs (random strings)
+2. Doesn't support using custom IDs (like Clerk's user IDs)
+3. Located at `apps/admin/src/lib/database/` not `@fitai/database`
+
+However, **Clerk webhooks require using Clerk's user IDs** to maintain consistency across systems.
+
+---
+
+## Solution
+
+Modified the webhook handler to use **direct SQLite operations** via `better-sqlite3` instead of the abstraction layer.
+
+### Why Direct SQL?
+
+1. **Custom IDs:** Need to use Clerk's `user_xxx` IDs, not auto-generated ones
+2. **Simplicity:** Webhooks are isolated operations, don't need full abstraction
+3. **Performance:** Direct SQL is faster for simple CRUD operations
+4. **Independence:** Webhooks shouldn't depend on application-level abstractions
+
+### Implementation
+
+**Before (broken):**
+```typescript
+import { db } from '@fitai/database';
+import { users } from '@fitai/database/schema';
+import { eq } from 'drizzle-orm';
+
+// Won't work - package doesn't exist in admin app
+await db.insert(users).values({...});
+```
+
+**After (working):**
+```typescript
+import Database from 'better-sqlite3';
+import path from 'path';
+
+const dbPath = path.join(process.cwd(), 'data', 'fitai.db');
+const db = new Database(dbPath);
+
+// Direct SQL with Clerk's user ID
+const stmt = db.prepare(`
+  INSERT INTO users (id, email, firstName, lastName, password, phone, role, createdAt, updatedAt)
+  VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)
+`);
+
+stmt.run(
+  clerkUserId,    // Use Clerk's ID
+  email,
+  firstName,
+  lastName,
+  '',             // Empty password (Clerk handles auth)
+  null,           // phone
+  role,
+  now,
+  now
+);
+
+db.close();      // Clean up connection
+```
+
+---
+
+## Changes Made
+
+### 1. Updated Imports
+
+```typescript
+// Removed
+import { getDatabase } from '@/lib/database';
+
+// Added
+import Database from 'better-sqlite3';
+import path from 'path';
+```
+
+### 2. Database Connection
+
+```typescript
+// Direct connection per request
+const dbPath = path.join(process.cwd(), 'data', 'fitai.db');
+const db = new Database(dbPath);
+```
+
+### 3. User Creation (user.created event)
+
+```typescript
+const stmt = db.prepare(`
+  INSERT INTO users (id, email, firstName, lastName, password, phone, role, createdAt, updatedAt)
+  VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)
+`);
+
+stmt.run(
+  id,                           // Clerk user ID
+  primaryEmail.email_address,
+  first_name || '',
+  last_name || '',
+  '',                           // Empty password
+  null,                         // No phone yet
+  role,                         // From public_metadata
+  now,                          // createdAt
+  now                           // updatedAt
+);
+
+db.close();
+```
+
+### 4. User Update (user.updated event)
+
+```typescript
+const stmt = db.prepare(`
+  UPDATE users
+  SET email = ?, firstName = ?, lastName = ?, role = ?, updatedAt = ?
+  WHERE id = ?
+`);
+
+stmt.run(
+  primaryEmail.email_address,
+  first_name || '',
+  last_name || '',
+  role,
+  now,
+  id
+);
+
+db.close();
+```
+
+### 5. User Delete (user.deleted event)
+
+```typescript
+const stmt = db.prepare('DELETE FROM users WHERE id = ?');
+stmt.run(id);
+db.close();
+```
+
+### 6. Database Type Updates
+
+**File:** `apps/admin/src/lib/database/types.ts`
+
+Added `trainer` role to User interface:
+
+```typescript
+role: 'admin' | 'trainer' | 'client'  // Was: 'admin' | 'client'
+```
+
+---
+
+## Key Features
+
+### ✅ Clerk User ID Preservation
+
+- Users created via Clerk have IDs like `user_2abc123xyz`
+- These IDs are preserved in the database
+- Maintains consistency between Clerk and database
+
+### ✅ Empty Password Field
+
+- Clerk users have empty string (`''`) for password
+- Clerk handles all authentication
+- No password needed in database
+
+### ✅ Role Synchronization
+
+- Reads role from Clerk `public_metadata.role`
+- Defaults to `'client'` if not set
+- Supports: `admin`, `trainer`, `client`
+
+### ✅ Connection Management
+
+- Opens connection at start of request
+- Closes connection after operation
+- Prevents connection leaks
+
+### ✅ Error Handling
+
+- Validates email presence
+- Validates user ID for deletion
+- Returns appropriate HTTP status codes
+- Closes database on errors
+
+---
+
+## Testing Verification
+
+After applying this fix:
+
+```bash
+# 1. Start dev server
+cd apps/admin
+npm run dev
+
+# 2. In another terminal, start Clerk CLI
+clerk listen --forward-url http://localhost:3000/api/webhooks
+
+# 3. Create a test user in Clerk Dashboard or via sign-up
+
+# 4. Expected output:
+✓ Received webhook with ID user_abc123 and type user.created
+✓ User user_abc123 created in database
+
+# 5. Verify in database
+cd ../../packages/database
+npm run db:studio
+# Check users table - should see user with Clerk ID
+```
+
+---
+
+## Database Schema Compatibility
+
+The webhook handler is compatible with the database schema:
+
+```sql
+CREATE TABLE users (
+  id TEXT PRIMARY KEY,           -- Clerk user ID (e.g., user_abc123)
+  email TEXT NOT NULL UNIQUE,
+  firstName TEXT NOT NULL,
+  lastName TEXT NOT NULL,
+  password TEXT,                 -- Optional (empty for Clerk users)
+  phone TEXT,
+  role TEXT NOT NULL DEFAULT 'client',
+  createdAt INTEGER NOT NULL,
+  updatedAt INTEGER NOT NULL
+);
+```
+
+---
+
+## Trade-offs
+
+### Pros ✅
+
+- **Works immediately** - No need to refactor entire abstraction layer
+- **Preserves Clerk IDs** - Maintains sync with Clerk
+- **Fast** - Direct SQL is performant
+- **Simple** - Easy to understand and maintain
+- **Isolated** - Doesn't affect other parts of the app
+
+### Cons ⚠️
+
+- **Bypasses abstraction** - Not using DatabaseFactory pattern
+- **SQL in handler** - Violates separation of concerns slightly
+- **No TypeScript validation** - Direct SQL has no type checking
+- **Duplication** - SQL logic separate from main database layer
+
+---
+
+## Future Improvements (Optional)
+
+If you want to align this with the abstraction layer in the future:
+
+### Option 1: Extend DatabaseFactory
+
+Add method to create user with custom ID:
+
+```typescript
+async createUserWithId(id: string, userData: Omit<User, 'id' | 'createdAt' | 'updatedAt'>): Promise<User> {
+  // Implementation that accepts custom ID
+}
+```
+
+### Option 2: Migrate to Drizzle ORM
+
+Replace `better-sqlite3` with Drizzle throughout:
+
+```typescript
+// Use Drizzle in admin app directly
+import { drizzle } from 'drizzle-orm/better-sqlite3';
+import { users } from '@fitai/database/schema';
+
+const db = drizzle(new Database(dbPath));
+await db.insert(users).values({ id: clerkId, ... });
+```
+
+### Option 3: Webhook-Specific Service
+
+Create a separate service for webhook operations:
+
+```typescript
+// apps/admin/src/lib/services/webhook-user-service.ts
+export class WebhookUserService {
+  async syncUserFromClerk(clerkUser: ClerkUser) {
+    // Handles sync with custom ID
+  }
+}
+```
+
+---
+
+## Performance Considerations
+
+### Connection Per Request
+
+Currently opens/closes DB per webhook:
+
+```typescript
+const db = new Database(dbPath);
+// ... operations ...
+db.close();
+```
+
+**Acceptable because:**
+- Webhooks are infrequent (< 10/min typically)
+- SQLite handles connections quickly (< 1ms)
+- Prevents connection leaks
+- Stateless and clean
+
+**For high volume (> 100/min):**
+- Consider connection pooling
+- Use singleton pattern
+- Or move to async queue (Redis + worker)
+
+---
+
+## Error Scenarios Handled
+
+| Scenario | Handling | HTTP Status |
+|----------|----------|-------------|
+| Missing webhook secret | Early return | 400 |
+| Invalid signature | Verification fails | 400 |
+| Missing Svix headers | Early return | 400 |
+| No primary email | Log + return | 400 |
+| No user ID (delete) | Log + return | 400 |
+| Database error | Try/catch + log | 500 |
+| Unknown event type | Log + continue | 200 |
+
+---
+
+## Files Modified
+
+1. ✅ `apps/admin/src/app/api/webhooks/route.ts` - Fixed imports and SQL
+2. ✅ `apps/admin/src/lib/database/types.ts` - Added `trainer` role
+3. ✅ This documentation file

+
+## Prerequisites
+
+Before testing webhooks, ensure you have:
+
+- ✅ Clerk account and application set up
+- ✅ Admin app running locally or deployed
+- ✅ Database schema updated (password field optional)
+- ✅ `CLERK_WEBHOOK_SECRET` environment variable set
+- ✅ `svix` package installed in admin app
+
+### Quick Setup Check
+
+```bash
+# 1. Check environment variables
+cat apps/admin/.env.local | grep CLERK_WEBHOOK_SECRET
+
+# 2. Verify svix is installed
+cd apps/admin
+npm list svix
+
+# 3. Check database schema
+cd ../../packages/database
+npm run db:push
+```
+
+---
+
+## Local Development Testing
+
+### Option 1: Using Clerk CLI (Recommended)
+
+The Clerk CLI forwards webhook events from Clerk to your local server.
+
+#### Step 1: Install Clerk CLI
+
+```bash
+npm install -g @clerk/clerk-cli
+```
+
+#### Step 2: Login to Clerk
+
+```bash
+clerk login
+```
+
+Follow the prompts to authenticate with your Clerk account.
+
+#### Step 3: Start Your Dev Server
+
+```bash
+cd apps/admin
+npm run dev
+```
+
+Your server should be running at `http://localhost:3000`
+
+#### Step 4: Start Webhook Forwarding
+
+In a **new terminal window**:
+
+```bash
+clerk listen --forward-url http://localhost:3000/api/webhooks
+```
+
+You'll see output like:
+```
+✓ Webhook forwarding is now active!
+✓ Webhook secret: whsec_xxxxxxxxxxxxxx
+
+Forwarding webhooks to: http://localhost:3000/api/webhooks
+```
+
+#### Step 5: Copy the Webhook Secret
+
+Copy the webhook secret from the output and add it to your `.env.local`:
+
+```env
+CLERK_WEBHOOK_SECRET=whsec_xxxxxxxxxxxxxx
+```
+
+Restart your dev server after adding the secret.
+
+#### Step 6: Test with a Real Sign-Up
+
+1. Go to your app (mobile or admin)
+2. Sign up a new user
+3. Watch both terminals:
+   - Clerk CLI terminal shows the webhook being forwarded
+   - Dev server terminal shows the processing logs
+
+Expected output:
+```
+Received webhook with ID user_abc123 and type user.created
+✅ User user_abc123 created in database
+```
+
+### Option 2: Using Webhook Testing Tools
+
+#### Using Svix Play (Web UI)
+
+1. Go to [Svix Play](https://www.svix.com/play/)
+2. Enter your webhook URL: `http://localhost:3000/api/webhooks`
+3. Select "Clerk" as the provider
+4. Choose event type: `user.created`
+5. Modify the payload if needed
+6. Click "Send"
+
+**Note:** You'll need to expose your local server (use ngrok) for this to work.
+
+#### Using ngrok for Local Testing
+
+If you need a public URL:
+
+```bash
+# Install ngrok
+npm install -g ngrok
+
+# Start ngrok
+ngrok http 3000
+```
+
+Use the ngrok URL (e.g., `https://abc123.ngrok.io/api/webhooks`) in Clerk Dashboard or Svix Play.
+
+---
+
+## Production Testing
+
+### Step 1: Configure Webhook Endpoint in Clerk Dashboard
+
+1. Go to [Clerk Dashboard](https://dashboard.clerk.com)
+2. Select your application
+3. Navigate to **Webhooks** in sidebar
+4. Click **Add Endpoint**
+
+#### Configure Endpoint:
+
+- **Endpoint URL:** `https://yourdomain.com/api/webhooks`
+- **Events to subscribe to:**
+  - ✅ `user.created`
+  - ✅ `user.updated`
+  - ✅ `user.deleted`
+
+#### Copy Signing Secret:
+
+After creating the endpoint, copy the **Signing Secret** and add it to your production environment variables:
+
+```env
+CLERK_WEBHOOK_SECRET=whsec_prod_xxxxxxxxxxxxxx
+```
+
+### Step 2: Send Test Event
+
+In Clerk Dashboard webhook settings:
+
+1. Click on your endpoint
+2. Click **Send Test Event**
+3. Select `user.created`
+4. Click **Send**
+
+### Step 3: Verify in Dashboard
+
+Check the webhook attempt logs:
+
+- **Status:** Should be `200 OK`
+- **Response:** `"Webhook processed successfully"`
+- **Response Time:** < 2 seconds typically
+
+### Step 4: Verify in Database
+
+Query your database to verify the test user was created:
+
+```sql
+SELECT * FROM users ORDER BY created_at DESC LIMIT 1;
+```
+
+---
+
+## Test Scenarios
+
+### Scenario 1: User Creation
+
+**Objective:** Verify new users are synced to database
+
+**Steps:**
+
+1. Create a new user via sign-up flow
+2. Check database for new user record
+3. Verify all fields are populated correctly
+
+**Expected Result:**
+
+```sql
+-- User should exist in database
+SELECT * FROM users WHERE id = 'user_abc123';
+
+-- Result:
+-- id: user_abc123
+-- email: test@example.com
+-- firstName: John
+-- lastName: Doe
+-- role: client (default)
+-- password: NULL or empty
+-- createdAt: [timestamp]
+-- updatedAt: [timestamp]
+```
+
+**Success Criteria:**
+- ✅ User record exists
+- ✅ Email matches Clerk
+- ✅ Name fields populated
+- ✅ Default role is 'client'
+- ✅ Timestamps are set
+
+### Scenario 2: User Update
+
+**Objective:** Verify user updates sync to database
+
+**Steps:**
+
+1. Update user profile in Clerk (name, email, or role)
+2. Check database for updated values
+3. Verify `updatedAt` timestamp changed
+
+**Update Name via Clerk Dashboard:**
+1. Go to Users → Select user
+2. Update First Name to "Jane"
+3. Click Save
+
+**Expected Result:**
+
+```sql
+SELECT * FROM users WHERE id = 'user_abc123';
+
+-- firstName should now be: Jane
+-- updatedAt should be newer than createdAt
+```
+
+**Success Criteria:**
+- ✅ User fields updated
+- ✅ `updatedAt` timestamp changed
+- ✅ `createdAt` timestamp unchanged
+
+### Scenario 3: Role Assignment
+
+**Objective:** Verify role metadata syncs correctly
+
+**Steps:**
+
+1. Set user role via Clerk Dashboard:
+   - Users → Select user
+   - Public Metadata: `{"role": "trainer"}`
+   - Save
+2. Check database for role update
+
+**Expected Result:**
+
+```sql
+SELECT id, email, role FROM users WHERE id = 'user_abc123';
+
+-- role should be: trainer
+```
+
+**Success Criteria:**
+- ✅ Role updated to 'trainer'
+- ✅ Role persisted in database
+- ✅ Webhook processed successfully
+
+### Scenario 4: User Deletion
+
+**Objective:** Verify user deletion cascades correctly
+
+**Steps:**
+
+1. Note user ID: `user_abc123`
+2. Delete user from Clerk Dashboard
+3. Check database - user should be deleted
+
+**Expected Result:**
+
+```sql
+-- User should not exist
+SELECT * FROM users WHERE id = 'user_abc123';
+-- Returns: 0 rows
+
+-- Related records should also be deleted (cascade)
+SELECT * FROM notifications WHERE user_id = 'user_abc123';
+-- Returns: 0 rows
+```
+
+**Success Criteria:**
+- ✅ User record deleted
+- ✅ Related records deleted (notifications, etc.)
+- ✅ No orphaned data
+
+### Scenario 5: Bulk User Creation
+
+**Objective:** Test webhook handling under load
+
+**Steps:**
+
+1. Import multiple users via Clerk Dashboard or API
+2. Verify all users created in database
+3. Check for any failed webhooks
+
+**Expected Result:**
+
+```sql
+-- All users should exist
+SELECT COUNT(*) FROM users WHERE created_at > NOW() - INTERVAL 5 MINUTE;
+-- Should match number of users created
+```
+
+**Success Criteria:**
+- ✅ All users synced
+- ✅ No duplicate entries
+- ✅ All webhook attempts successful
+
+---
+
+## Verification Steps
+
+### 1. Check Webhook Logs (Clerk Dashboard)
+
+**Location:** Clerk Dashboard → Webhooks → Your Endpoint
+
+**What to Check:**
+- **Status Code:** Should be `200`
+- **Response Time:** Typically < 2 seconds
+- **Response Body:** `"Webhook processed successfully"`
+- **Attempts:** Should be 1 (no retries needed)
+
+**Red Flags:**
+- ❌ Status 400: Verification failed (wrong secret)
+- ❌ Status 500: Server error (check logs)
+- ❌ Multiple attempts: Server issues or slow response
+
+### 2. Check Server Logs
+
+**Look for these log messages:**
+
+```bash
+# Success logs
+✅ User user_abc123 created in database
+✅ User user_abc123 updated in database
+✅ User user_abc123 deleted from database
+
+# Info logs
+Received webhook with ID user_abc123 and type user.created
+
+# Error logs (should not appear)
+❌ Error verifying webhook: [details]
+❌ Error processing webhook: [details]
+❌ No primary email found for user: [id]
+```
+
+### 3. Verify Database State
+
+**Query Templates:**
+
+```sql
+-- Check recent users
+SELECT * FROM users ORDER BY created_at DESC LIMIT 10;
+
+-- Check user count by role
+SELECT role, COUNT(*) as count FROM users GROUP BY role;
+
+-- Check for users without required fields
+SELECT * FROM users WHERE email IS NULL OR firstName = '' OR lastName = '';
+
+-- Check for orphaned records (shouldn't exist after cascade delete)
+SELECT n.* FROM notifications n 
+LEFT JOIN users u ON n.user_id = u.id 
+WHERE u.id IS NULL;
+```
+
+### 4. Test Role Assignment API
+
+**Using curl:**
+
+```bash
+# Get your auth token from Clerk
+TOKEN="your_clerk_session_token"
+
+# Set user role
+curl -X POST http://localhost:3000/api/admin/set-role \
+  -H "Content-Type: application/json" \
+  -H "Authorization: Bearer $TOKEN" \
+  -d '{
+    "targetUserId": "user_abc123",
+    "role": "trainer"
+  }'
+
+# Expected response:
+# {
+#   "success": true,
+#   "message": "User role updated to trainer",
+#   "user": { ... }
+# }
+```
+
+---
+
+## Common Issues
+
+### Issue 1: Webhook Returns 400 - Verification Failed
+
+**Symptoms:**
+```
+Error verifying webhook: [Svix error details]
+Status: 400
+```
+
+**Causes:**
+- Wrong webhook secret
+- Missing Svix headers
+- Replay attack (old timestamp)
+
+**Solutions:**
+
+1. **Verify webhook secret:**
+   ```bash
+   echo $CLERK_WEBHOOK_SECRET
+   # Should start with whsec_
+   ```
+
+2. **Regenerate secret:**
+   - Go to Clerk Dashboard → Webhooks
+   - Click your endpoint → Rotate Secret
+   - Update `.env.local` with new secret
+   - Restart server
+
+3. **Check headers:**
+   ```typescript
+   // Add debug logging to webhook handler
+   console.log('Headers:', {
+     svix_id: headerPayload.get('svix-id'),
+     svix_timestamp: headerPayload.get('svix-timestamp'),
+     svix_signature: headerPayload.get('svix-signature'),
+   });
+   ```
+
+### Issue 2: User Not Created in Database
+
+**Symptoms:**
+- Webhook returns 200
+- Server logs show success
+- User not in database
+
+**Solutions:**
+
+1. **Check database connection:**
+   ```bash
+   cd packages/database
+   npm run db:studio
+   # Verify you can see the database
+   ```
+
+2. **Check for unique constraint violations:**
+   ```sql
+   -- Check if user with email already exists
+   SELECT * FROM users WHERE email = 'test@example.com';
+   ```
+
+3. **Verify schema migration ran:**
+   ```bash
+   cd packages/database
+   npm run db:push
+   ```
+
+4. **Check server logs for SQL errors:**
+   ```
+   Error processing webhook: UNIQUE constraint failed: users.email
+   ```
+
+### Issue 3: Role Not Updating
+
+**Symptoms:**
+- Webhook processed successfully
+- Role in database doesn't change
+
+**Solutions:**
+
+1. **Verify metadata format in Clerk:**
+   ```json
+   {
+     "role": "admin"
+   }
+   ```
+   (Should be in **Public Metadata**, not Private or Unsafe)
+
+2. **Check role value:**
+   - Must be exactly: `admin`, `trainer`, or `client`
+   - Case-sensitive
+   - No extra spaces
+
+3. **Force webhook retry:**
+   - Update any field on the user
+   - This triggers `user.updated` webhook
+
+### Issue 4: Webhook Not Received
+
+**Symptoms:**
+- Event in Clerk
+- No webhook attempt logged
+- Server never hit
+
+**Solutions:**
+
+1. **Verify endpoint URL in Clerk Dashboard:**
+   ```
+   Production: https://yourdomain.com/api/webhooks
+   Local (with ngrok): https://abc123.ngrok.io/api/webhooks
+   ```
+
+2. **Check subscribed events:**
+   - Ensure `user.created`, `user.updated`, `user.deleted` are checked
+
+3. **Verify server is accessible:**
+   ```bash
+   # Test endpoint manually
+   curl -X POST https://yourdomain.com/api/webhooks \
+     -H "Content-Type: application/json" \
+     -d '{"test": true}'
+   
+   # Should return 400 (missing headers), not 404
+   ```
+
+4. **Check firewall/security rules:**
+   - Ensure Clerk IPs not blocked
+   - HTTPS must be valid (not self-signed cert)
+
+### Issue 5: Slow Webhook Processing
+
+**Symptoms:**
+- Webhook takes > 5 seconds
+- Clerk retries multiple times
+- Timeouts
+
+**Solutions:**
+
+1. **Optimize database queries:**
+   ```typescript
+   // Add indexes
+   // Run migrations separately
+   // Use transactions for bulk operations
+   ```
+
+2. **Add timeout handling:**
+   ```typescript
+   // Process webhook asynchronously
+   // Return 200 immediately
+   // Handle sync in background
+   ```
+
+3. **Check database connection pool:**
+   ```typescript
+   // Ensure connection pool is sized correctly
+   // Close connections properly
+   ```
+
+---
+
+## Automated Testing
+
+### Unit Test Example
+
+```typescript
+// apps/admin/__tests__/webhook.test.ts
+import { POST } from '@/app/api/webhooks/route';
+
+describe('Webhook Handler', () => {
+  it('should create user on user.created event', async () => {
+    const mockRequest = new Request('http://localhost/api/webhooks', {
+      method: 'POST',
+      headers: {
+        'svix-id': 'msg_test',
+        'svix-timestamp': Date.now().toString(),
+        'svix-signature': 'test_signature',
+      },
+      body: JSON.stringify({
+        type: 'user.created',
+        data: {
+          id: 'user_test123',
+          email_addresses: [
+            {
+              id: 'email_test',
+              email_address: 'test@example.com',
+            },
+          ],
+          primary_email_address_id: 'email_test',
+          first_name: 'Test',
+          last_name: 'User',
+          public_metadata: { role: 'client' },
+        },
+      }),
+    });
+
+    const response = await POST(mockRequest);
+    expect(response.status).toBe(200);
+  });
+});
+```
+
+---
+
+## Monitoring Checklist
+
+Use this checklist for ongoing webhook monitoring:
+
+- [ ] Check webhook success rate in Clerk Dashboard (should be > 99%)
+- [ ] Monitor webhook response times (should be < 2s)
+- [ ] Review failed webhook attempts weekly
+- [ ] Verify user count in Clerk matches database
+- [ ] Check for orphaned records monthly
+- [ ] Test role assignment flow quarterly
+- [ ] Review webhook logs for errors
+- [ ] Validate cascade deletes are working
+
+---
+
+## Next Steps After Testing
+
+Once webhooks are tested and working:
+
+1. ✅ **Document for your team** - Share this guide
+2. ✅ **Set up monitoring** - Use Clerk Dashboard or custom monitoring
+3. ✅ **Plan for scale** - Consider async processing for high volume
+4. ✅ **Implement role UI** - Build admin interface for role management
+5. ✅ **Add audit logging** - Track who changes what roles
+6. ✅ **Test failure scenarios** - What happens if database is down?
