+# Webhook Relay Integration Analysis
+
+## 🔍 Current Implementation Analysis
+
+### Architecture Overview
+The current "Baton" webhook relay system demonstrates a sophisticated approach to webhook handling with the following components:
+
+1. **Dual Server Architecture**:
+   - **Ingest Server (Port 4000)**: Handles incoming webhooks via subdomain routing
+   - **Relay Server (Port 4200)**: Manages WebSocket connections and authentication
+
+2. **Key Technologies**:
+   - **Hono**: Fast web framework for API routes
+   - **Bun**: JavaScript runtime for server execution
+   - **Prisma**: Database ORM with PostgreSQL
+   - **Auth.js**: Authentication with GitHub OAuth
+   - **WebSockets**: Real-time bidirectional communication
+
+3. **Data Flow**:
+   ```
+   External Service → Subdomain Webhook → Database Log → WebSocket Broadcast → Connected Clients
+   ```
+
+## 🎯 SvelteKit Integration Opportunities
+
+### 1. **Unified Application Architecture**
+
+**Benefits of SvelteKit Integration**:
+- **Single Codebase**: Eliminates dual server complexity
+- **File-based Routing**: Intuitive API endpoint organization
+- **SSR/SPA Hybrid**: Optimal performance for dashboard UI

+
+**Implementation Strategy**:
+```
+Current: Hono Server (Port 4000) + Hono Server (Port 4200)
+New:     SvelteKit App with API Routes + Frontend
+```
+
+### 2. **Enhanced Real-time Communication**
+
+**Server-Sent Events vs WebSockets**:
+
+| Aspect | WebSockets (Current) | SSE (Recommended) |
+|--------|---------------------|-------------------|
+| Complexity | High (bidirectional) | Low (unidirectional) |
+| Browser Support | Good | Excellent |
+| Reconnection | Manual | Automatic |
+| Resource Usage | Higher | Lower |

+- **HTTP/2 Multiplexing**: Better performance
+- **Simpler Error Handling**: Standard HTTP error codes
+- **Lower Resource Usage**: No need for bidirectional communication
+
+### 3. **Modern Frontend Integration**
+
+**Svelte Store Architecture**:
+```typescript
+// Real-time webhook events
+export const webhookEvents = writable<WebhookEvent[]>([]);
+
+// Connection management
+export const connectionStatus = writable<'connected' | 'disconnected'>('disconnected');
+
+// Derived computed values
+export const recentEvents = derived(webhookEvents, events => events.slice(0, 10));
+```
+
+**Benefits**:
+- **Reactive UI**: Automatic updates when data changes
+- **Type Safety**: Full TypeScript integration
+- **Performance**: Efficient reactivity system
+- **Developer Experience**: Intuitive state management
+
+## 🔄 Integration Modifications
+
+### 1. **Routing System Transformation**
+
+**Current Subdomain Handling**:
+```typescript
+// Hono-based subdomain extraction
+const urlParts = url.hostname.split(".");
+const subdomain = urlParts[0];
+```
+
+**SvelteKit Dynamic Routes**:
+```typescript
+// File: src/routes/api/webhook/[subdomain]/+server.ts
+export const POST: RequestHandler = async ({ params }) => {
+  const { subdomain } = params; // Automatic parameter extraction
+};
+```
+
+### 2. **Authentication Integration**
+
+**Current Implementation**:
+- Separate auth middleware in Hono
+- Manual session management
+- Custom cookie handling
+
+**SvelteKit Integration**:
+- **Auth.js Integration**: Native SvelteKit support
+- **Hooks System**: Server-side authentication middleware
+- **Type-safe Sessions**: Automatic session typing
+
+```typescript
+// hooks.server.ts - Automatic auth handling
+export const handle = sequence(authHandle, customHandle);
+```
+
+### 3. **Database Optimization**
+
+**Enhanced Schema**:
+```prisma
+model WebhookEvent {
+  // ... existing fields
+  @@index([userId, createdAt]) // Performance optimization
+}
+
+model RelayTarget {
+  // ... existing fields  
+  @@index([userId, active])    // Query optimization
+}
+```
+
+### 4. **Real-time Communication Upgrade**
+
+**Current WebSocket Implementation**:
+```typescript
+// Manual connection management
+const clients: Map<string, WSContext[]> = new Map();
+
+// Manual broadcasting
+clients.get(subdomain)?.forEach((ws) => {
+  ws.send(JSON.stringify(message));
+});
+```
+
+**New SSE Implementation**:
+```typescript
+// Automatic connection lifecycle
+export function addSSEConnection(userId: string, controller: ReadableStreamDefaultController) {
+  // Automatic cleanup and management
+}
+
+// Type-safe broadcasting
+export async function broadcastToUser(userId: string, event: WebhookEvent) {
+  // Reliable message delivery with error handling
+}
+```
+
+## 🚀 Advanced Integration Features
+
+### 1. **Webhook Transformation Pipeline**
+
+```typescript
+// src/lib/server/transformers.ts
+export interface WebhookTransformer {
+  name: string;
+  transform: (payload: any) => any;
+  condition?: (payload: any) => boolean;
+}
+
+export const transformers: WebhookTransformer[] = [
+  {
+    name: 'GitHub to Slack',
+    condition: (payload) => payload.repository && payload.action,
+    transform: (payload) => ({
+      text: `${payload.action} on ${payload.repository.name}`,
+      username: payload.sender.login
+    })
+  }
+];
+```
+
+### 2. **Multi-tenant Subdomain Management**
+
+```typescript
+// src/lib/server/subdomain.ts
+export async function createUserSubdomain(userId: string, preferredSubdomain?: string) {
+  const subdomain = preferredSubdomain || generateUniqueSubdomain();
+  
+  // Validate subdomain availability
+  const existing = await prisma.user.findUnique({ where: { subdomain } });
+  if (existing) {
+    throw new Error('Subdomain already taken');
+  }
+  
+  return subdomain;
+}
+```
+
+### 3. **Webhook Analytics Dashboard**
+
+```typescript
+// Enhanced analytics with aggregated data
+export async function getWebhookAnalytics(userId: string, timeRange: string) {
+  const events = await prisma.webhookEvent.groupBy({
+    by: ['method', 'path'],
+    where: {
+      userId,
+      createdAt: { gte: getTimeRangeStart(timeRange) }
+    },
+    _count: true
+  });
+  
+  return events;
+}
+```
+
+### 4. **Advanced Relay Features**
+
+**Conditional Forwarding**:
+```typescript
+export interface RelayRule {
+  condition: string; // JSONPath or simple condition
+  target: string;
+  transform?: string;
+}
+
+// Example: Only forward GitHub push events
+{
+  condition: "$.action === 'push'",
+  target: "https://api.example.com/github-push",
+  transform: "{ commit: $.head_commit.id, repo: $.repository.name }"
+}
+```
+
+**Retry Logic**:
+```typescript
+export async function forwardWithRetry(target: string, payload: any, maxRetries = 3) {
+  for (let attempt = 1; attempt <= maxRetries; attempt++) {
+    try {
+      const response = await fetch(target, {
+        method: 'POST',
+        headers: { 'Content-Type': 'application/json' },
+        body: JSON.stringify(payload)
+      });
+      
+      if (response.ok) return { success: true };
+      
+      if (attempt === maxRetries) throw new Error(`Failed after ${maxRetries} attempts`);
+      
+      // Exponential backoff
+      await new Promise(resolve => setTimeout(resolve, Math.pow(2, attempt) * 1000));
+    } catch (error) {
+      if (attempt === maxRetries) throw error;
+    }
+  }
+}

+## 📡 API Endpoints
+
+### Webhook Ingestion
+- `POST /api/webhook/{subdomain}` - Receive webhooks for a specific user
+
+### Relay Management
+- `GET /api/relay/events` - Server-Sent Events stream for real-time updates
+- `GET /api/relay/targets` - List user's relay targets
+- `POST /api/relay/targets` - Add new relay target
+- `DELETE /api/relay/targets` - Remove relay target
+
+### Webhook History
+- `GET /api/webhooks` - Get webhook event history
+
+## 🔄 Real-time Communication
+
+The system uses **Server-Sent Events (SSE)** instead of WebSockets for several advantages:
+
+1. **Simpler Implementation**: No need for bidirectional communication
+2. **Better Browser Support**: Native EventSource API
+3. **Automatic Reconnection**: Built-in reconnection logic
+4. **HTTP/2 Multiplexing**: Better performance over HTTP/2
+
+### SSE Connection Flow
+
+1. Client connects to `/api/relay/events`
+2. Server maintains connection map by user ID
+3. Incoming webhooks trigger real-time broadcasts
+4. Automatic heartbeat keeps connections alive
+
+## 🎯 Usage Example
+
+1. **Sign in** with GitHub
+2. **Get your webhook endpoint**: `https://yourdomain.com/api/webhook/{your-subdomain}`
+3. **Configure external services** to send webhooks to your endpoint
+4. **Add relay targets** to forward webhooks to your services
+5. **Monitor events** in real-time through the dashboard
+
+## 🔒 Security Features
+
+- **Authentication Required**: All dashboard routes protected
+- **User Isolation**: Webhooks isolated by subdomain/user
+- **Header Filtering**: Sensitive headers excluded from logs
+- **Input Validation**: Zod schemas for API validation
+
+## 🚀 Deployment
+
+### Vercel (Recommended)
+```bash
+npm install @sveltejs/adapter-vercel
+# Update svelte.config.js to use vercel adapter
+npm run build
+```
+
+### Other Platforms
+- **Netlify**: Use `@sveltejs/adapter-netlify`
+- **Cloudflare**: Use `@sveltejs/adapter-cloudflare`
+- **Node.js**: Use `@sveltejs/adapter-node`

+
+For production use with custom domains, configure your DNS and load balancer to route subdomains to your SvelteKit application:
+
+```nginx
+# Nginx example
+server {
+    server_name *.yourdomain.com;
+    location / {
+        proxy_pass http://your-sveltekit-app;
+        proxy_set_header Host $host;
+    }
+}
+```
+
+### Webhook Forwarding
+
+The system supports forwarding webhooks to multiple targets with:
+- **Automatic retries** for failed requests
+- **Custom headers** for identification
+- **Error logging** and monitoring
+
+## 📊 Monitoring
+
+- Real-time event count in dashboard
