A Val Town application for managing and viewing demos with authentication.

• Authentication: Google OAuth via LastLogin
• Dashboard: User-friendly interface showing system status
• Health Monitoring: Real-time system health checks
• Modular Architecture: Clean separation of concerns

This application uses LastLogin for authentication:

• Login: Users sign in with their Google account
• Protected Routes: All routes require authentication except public endpoints
• Logout: Users can logout via /auth/logout (handled automatically by LastLogin)
• Session Management: Automatic session validation and renewal

The following routes are accessible without authentication:

• /api/health - System health status

Routes are protected by different authentication mechanisms:

User Authentication (Google OAuth via LastLogin):

• / - Main dashboard (shows user info and system status)
• /api/* - API endpoints (except health)
• /views/* - View routes including /views/glimpse/:id
• /glimpse/* - Shortcut routes including /glimpse/:id (equivalent to /views/glimpse/:id)

Webhook Authentication (X-API-KEY header):

• /tasks/* - Webhook endpoints for external integrations (POST requests only)
  • GET requests to /tasks/* are allowed without authentication for debug endpoints

The application provides two equivalent routes for accessing page data:

• GET /views/glimpse/:id - Get page data by Notion page ID

• GET /glimpse/:id - Same functionality as above, shorter URL

Both routes:

• Require user authentication
• Use the same controller (glimpseHandler)
• Return identical JSON responses
• Filter out button properties from Notion page data

The dashboard displays both routes in a comparison table for easy testing.

The application is built with:

• Hono: Web framework for routing and middleware
• LastLogin: Authentication service
• TypeScript: Type-safe development
• Val Town: Hosting platform

The application supports webhook endpoints for external integrations (like Notion webhooks):

Set the webhook secret in your environment:

NOTION_WEBHOOK_SECRET=your-secret-key-here

• POST /tasks/notion-webhook - Main webhook endpoint for Notion integrations (requires X-API-KEY header)
• POST /tasks/url - Updates Notion page URL property with glimpse URL (requires X-API-KEY header)
• POST /tasks/test - Test endpoint for webhook authentication (requires X-API-KEY header)
• GET /tasks/debug-webhook - Debug endpoint to check webhook configuration

Webhook endpoints require the X-API-KEY header:

curl -X POST https://your-val.web.val.run/tasks/test \
  -H "X-API-KEY: your-secret-key-here"

Use the webhook testing form in the dashboard:

1. Navigate to your dashboard at /
2. Find the "Webhook Endpoint" section
3. Enter your NOTION_WEBHOOK_SECRET value
4. Click "Test Webhook" to verify authentication

Configure these environment variables for full functionality:

• GLANCE_DEMOS_DB_ID - Notion database ID for demos
• GLANCE_CONTENT_DB_ID - Notion database ID for content
• GLANCE_INTERACTIONS_DB_ID - Notion database ID for interactions
• NOTION_API_KEY - Notion API key for database access
• NOTION_WEBHOOK_SECRET - Secret key for webhook authentication
