A Val Town application for managing and viewing Notion-based demo content with webhook integration.

This application follows a strict layered architecture:

• Services (/backend/services/) - Pure API calls to external systems
• Controllers (/backend/controllers/) - Business logic and orchestration
• Routes (/backend/routes/) - HTTP request/response handling

• GET / - Dashboard with system health and demo links
• GET /api/health - System health status (public)
• GET /views/glimpse/:id - Notion page data with related content as JSON (filtered for data consumption)
• GET /glimpse/:id - Same as above, alternative endpoint

All webhook endpoints require X-API-KEY header with NOTION_WEBHOOK_SECRET value.

• POST /tasks/test - Test webhook authentication
• POST /tasks/url - Update Notion page with glimpse URL (requires X-API-KEY header)
• POST /tasks/notion-webhook - General Notion webhook handler (requires X-API-KEY header)
• GET /tasks/debug-webhook - Check webhook configuration (requires X-API-KEY header)

Required environment variables (add to vars.env):

• NOTION_API_KEY - Notion integration API key
• NOTION_WEBHOOK_SECRET - Secret for webhook authentication
• 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

• Google OAuth Authentication - Secure user authentication via LastLogin
• Notion Integration - Read and update Notion pages and databases
• Webhook Support - Automated URL updates from Notion
• Health Monitoring - System status and database connectivity checks
• Interactive Dashboard - Test endpoints and view demo links

The application uses:

• Hono - Web framework for API routes
• LastLogin - Authentication service
• Notion API - Database and page management
• TypeScript - Type safety and development experience
