## 🚀 NEXT STEPS (5 Minutes)

### 1️⃣ Get Firebase Credentials

Go to Firebase Console: https://console.firebase.google.com/

1. Select your project (or create new one)
2. Go to **Project Settings** → **Cloud Messaging**
3. Copy your **Server Key**
4. Go to **Project Settings** → **General** → **Your apps** → **Web app**
5. Copy all Firebase config values

### 2️⃣ Update .env File

Add these variables to your `.env` file:

```env
FCM_SERVER_KEY=YOUR_SERVER_KEY_FROM_FIREBASE
FIREBASE_API_KEY=YOUR_API_KEY
FIREBASE_AUTH_DOMAIN=your-project.firebaseapp.com
FIREBASE_PROJECT_ID=your-project-id
FIREBASE_STORAGE_BUCKET=your-project.appspot.com
FIREBASE_MESSAGING_SENDER_ID=YOUR_SENDER_ID
FIREBASE_APP_ID=YOUR_APP_ID
FIREBASE_VAPID_PUBLIC_KEY=BPlDvtfqfzg7F9YTLwO-WGtJsrucariD1GCEenN6oayU58X0hCdRqaNfqgTZeNchkoED_uceuaOprdMX74pdQDc
FIREBASE_VAPID_PRIVATE_KEY=HeLyHGL8l7D3Re4DXwNMlIwJ6Zd33VkZrzv7DZaBBps
```

### 3️⃣ Update Service Worker

Edit `public/firebase-messaging-sw.js` (line 13-20):

```javascript
const firebaseConfig = {
  apiKey: "YOUR_FIREBASE_API_KEY",
  authDomain: "YOUR_PROJECT_ID.firebaseapp.com",
  projectId: "YOUR_PROJECT_ID",
  storageBucket: "YOUR_PROJECT_ID.appspot.com",
  messagingSenderId: "YOUR_MESSAGING_SENDER_ID",
  appId: "YOUR_APP_ID",
};
```

### 4️⃣ Add to Your Layout

Add to `resources/views/layouts/app.blade.php` (or your main layout):

```html
<!-- Before closing </body> tag -->

<!-- Firebase SDK -->
<script src="https://www.gstatic.com/firebasejs/9.22.0/firebase-app-compat.js"></script>
<script src="https://www.gstatic.com/firebasejs/9.22.0/firebase-messaging-compat.js"></script>

<!-- Firebase Config -->
<script>
  window.FIREBASE_API_KEY = "{{ env('FIREBASE_API_KEY') }}";
  window.FIREBASE_AUTH_DOMAIN = "{{ env('FIREBASE_AUTH_DOMAIN') }}";
  window.FIREBASE_PROJECT_ID = "{{ env('FIREBASE_PROJECT_ID') }}";
  window.FIREBASE_STORAGE_BUCKET = "{{ env('FIREBASE_STORAGE_BUCKET') }}";
  window.FIREBASE_MESSAGING_SENDER_ID =
    "{{ env('FIREBASE_MESSAGING_SENDER_ID') }}";
  window.FIREBASE_APP_ID = "{{ env('FIREBASE_APP_ID') }}";
</script>

<!-- FCM Notification Manager -->
<script src="{{ asset('js/fcm-notifications.js') }}"></script>
```

### 5️⃣ Add Notify Button to Program Page

In your program details page, add:

```blade
@include('components.notify-button', ['programId' => $program->id])
```

---

## 🧪 TEST IT!

### Test 1: Subscribe to Notifications

1. Go to a program page
2. Click "Notify Me" button
3. Allow notifications when prompted
4. Button should change to "Unnotify"

### Test 2: Send Test Notification

```bash
curl -X POST http://localhost/api/webhooks/test-notification \
  -H "Content-Type: application/json" \
  -d '{"program_id": 1}'
```

You should receive a test notification!

### Test 3: Webhook - New Episode

```bash
curl -X POST http://localhost/api/webhooks/new-episode \
  -H "Content-Type: application/json" \
  -d '{
    "program_id": 1,
    "episode_title": "Test Episode",
    "episode_description": "This is a test",
    "episode_url": "http://localhost/episode/1"
  }'
```

## 🔍 Database Schema

Table: `fcm_tokens`

```
id              - Primary key
user_id         - Foreign key to users table
token           - FCM token (unique)
topic           - Firebase topic (e.g., "program-123")
device_type     - Device type (web, android, ios)
subscribed_at   - Timestamp of subscription
created_at      - Created timestamp
updated_at      - Updated timestamp
```

---

## 🎨 How It Works

1. **User clicks "Notify Me"**

   - Browser requests notification permission
   - FCM token is generated
   - Token saved to database
   - User subscribed to `program-{id}` topic

2. **New Episode Added (via webhook)**

   - Your CMS/Backend sends POST to `/api/webhooks/new-episode`
   - Laravel sends notification to topic `program-{id}`
   - All subscribed users receive push notification

3. **User clicks "Unnotify"**
   - Token unsubscribed from topic
   - Database record removed
   - User stops receiving notifications

---

## 💡 Example Integration

When you create a new episode in your admin panel:

```php
// In your Episode creation logic
$episode = Episode::create([...]);

// Send notification to subscribers
$webhookUrl = url('/api/webhooks/new-episode');
Http::post($webhookUrl, [
    'program_id' => $episode->program_id,
    'episode_title' => $episode->title,
    'episode_description' => $episode->description,
    'episode_url' => url("/episodes/{$episode->id}")
]);
```
