## 🚀 How to Use

### For Website Integration

**Quick Start (2 steps):**

1. Get your site key from administrator
2. Add this code before `</body>`:

```html
<script>
  window.SpectrumChatConfig = {
    apiUrl: 'https://your-api-domain.com/api/v1/conversations',
    siteKey: 'pub_customer_xyz123',
    title: 'Help Center',
    enableCitations: true
  };
</script>
<script src="https://unpkg.com/@spectrumsense/spectrum-chat@latest/dist/spectrum-chat.js"></script>
```

**That's it!** JWT authentication is enabled automatically.

### For Testing

**Local Testing:**

1. **Ensure API is running:** `http://localhost:8000`
2. **Ensure widget server is running:** `http://localhost:3000`
3. **Open test page:** `http://localhost:3000/test-security.html`
4. **Run tests:** Click buttons to test session creation, conversations, etc.

**Or test the simple example:**
- Open: `http://localhost:3000/example-integration.html`
- Click the chat button in bottom-right corner
- Start chatting!

## 🔒 Security Features

### Automatic & Transparent

All security is handled automatically - no configuration needed:

1. **Session Creation** - JWT token created on first message
2. **Origin Validation** - API verifies requests from whitelisted domains
3. **Token Refresh** - Tokens refresh automatically before expiration
4. **Conversation Protection** - Conversations bound to origin domain
5. **Error Recovery** - Auto-retry on token expiration or stale conversations

### What You See in Browser

**Session Storage:**
```javascript
// Automatically created and managed
'spectrum-chat-conversation-id'  // Current conversation
'spectrum-chat-token'             // JWT token data
'spectrum-chat-messages'          // Message history
```

**Network Requests:**
```http
POST /api/v1/sessions
POST /api/v1/conversations
POST /api/v1/conversations/{id}

Headers:
  Origin: http://localhost:3000 (automatic)
  Authorization: Bearer eyJhbGci... (automatic)
```

---

## 📋 API Configuration Required

Before using the widget, ensure your API has:

1. **Organization Created:**
   - Name: BrightSpectrum (or your org)
   - Site Key: `pub_bright_spectrum_htlzbncn`
   - Status: Active

2. **Allowed Origins Configured:**
   ```python
   allowed_origins = [
       'http://localhost:3000',      # For testing
       'https://www.yoursite.com',   # Production
       'https://yoursite.com'        # Production (no www)
   ]
   ```

3. **Endpoints Available:**
   - POST `/api/v1/sessions` - Create JWT token
   - POST `/api/v1/conversations` - Start conversation
   - POST `/api/v1/conversations/{id}` - Continue conversation

## 🎯 What Changed

### From Legacy Version

**Before:**
- No security
- No token management
- No origin validation
- Manual tenant_id

**After (Current):**
- ✅ JWT authentication by default
- ✅ Automatic token management
- ✅ Origin validation
- ✅ Site-key authentication
- ✅ Auto-refresh tokens
- ✅ Conversation protection
- ✅ Error recovery
- ✅ Backward compatible (tenant_id still works)

### Default Configuration

```javascript
{
  apiUrl: 'http://localhost:8000/api/v1/conversations',
  siteKey: 'pub_bright_spectrum_htlzbncn',
  useJWT: true,        // ← JWT enabled by default
  enableCitations: true,
  debug: true          // For testing (disable in production)
}
```

## 🚦 Next Steps

### For Development

1. ✅ API configured with allowed origins
2. ✅ Test page working (`http://localhost:3000/test-security.html`)
3. ⏭️ Test all scenarios (session, conversation, continue)
4. ⏭️ Verify token refresh works
5. ⏭️ Test widget integration end-to-end

### For Production

1. ⏭️ Update API URL to production
2. ⏭️ Add production domains to allowed origins
3. ⏭️ Disable debug mode (`debug: false`)
4. ⏭️ Test on staging environment
5. ⏭️ Deploy to production
6. ⏭️ Monitor error logs
