# Admin Auto-Redirect Implementation

## ✅ **COMPLETE: Admins Now Redirect to /admin Automatically**

### **Overview**
Modified all authentication flows to automatically redirect admin users to `/admin` instead of the member dashboard (`/`).

---

## **📝 Changes Made**

### **1. Login Page** (`/apps/web/src/components/pages/Login.tsx`)
**Already Implemented** ✅
- Lines 42-46: Checks `result.user?.role === 'admin'`
- Redirects admins to `/admin`
- Redirects regular users to `/`

```typescript
if (result.user?.role === 'admin') {
  navigate('/admin')
} else {
  navigate('/')
}
```

---

### **2. OTP Verification** (`/apps/web/src/components/pages/OtpVerification.tsx`)
**Fixed** ✅
- Lines 60-66: Now checks user role after OTP verification
- Redirects based on role

**Before:**
```typescript
await verifyOtp(tempToken, code, method)
navigate('/') // Always went to member dashboard
```

**After:**
```typescript
const result = await verifyOtp(tempToken, code, method)
if (result.user?.role === 'admin') {
  navigate('/admin')
} else {
  navigate('/')
}
```

---

### **3. Auth Callback (Google OAuth)** (`/apps/web/src/components/pages/AuthCallback.tsx`)
**Fixed** ✅
- Lines 22-36: Fetches user data to check role
- Redirects based on role

**Before:**
```typescript
localStorage.setItem('token', token)
window.location.href = '/' // Always went to member dashboard
```

**After:**
```typescript
localStorage.setItem('token', token)

// Fetch user to check role
const response = await axios.get(`${API_URL}/api/auth/me`, {
  headers: { Authorization: `Bearer ${token}` }
})

// Redirect based on role
if (response.data.role === 'admin') {
  window.location.href = '/admin'
} else {
  window.location.href = '/'
}
```

---

### **4. Public Route Guard** (`/apps/web/src/App.tsx`)
**Fixed** ✅
- Lines 55-58: Prevents logged-in users from accessing login/register
- Now redirects admins to `/admin` instead of `/`

**Before:**
```typescript
if (user) {
  return <Navigate to="/" replace /> // Always went to member dashboard
}
```

**After:**
```typescript
if (user) {
  // Redirect based on role
  const redirectTo = user.role === 'admin' ? '/admin' : '/'
  return <Navigate to={redirectTo} replace />
}
```

## **🎯 User Flows**

### **Admin Login Flow:**
```
1. Admin goes to /auth/login
2. Enters credentials
3. Clicks "Sign In"
   ↓
4a. If NO OTP required:
    → Redirected to /admin ✅
   
4b. If OTP required:
    → Goes to /auth/otp
    → Enters OTP code
    → Redirected to /admin ✅
```

### **Admin Google OAuth Flow:**
```
1. Admin clicks "Continue with Google"
2. Completes Google authentication
3. Redirected to /auth/callback
   ↓
4a. If NO OTP required:
    → Redirected to /admin ✅
   
4b. If OTP required:
    → Goes to /auth/otp
    → Enters OTP code
    → Redirected to /admin ✅
```

### **Admin Already Logged In:**
```
1. Admin is already logged in
2. Admin tries to access /auth/login or /auth/register
   ↓
3. PublicRoute guard intercepts
4. Redirected to /admin ✅
```

### **Regular User Flows:**
All regular users continue to be redirected to `/` (member dashboard) as before.
