121### Backend (`/backend`)
122
123Handles all server-side operations including API routes, Notion integration, and static file serving. Built with Hono for routing and includes authentication middleware.
124
125### Frontend (`/frontend`)
134
135- **Val Town & Deno**: Serverless runtime environment with TypeScript support
136- **Notion Client**: Official npm library for Notion API integration
137- **Hono**: Lightweight web framework for routing and middleware
138- **Blob Storage**: Val Town's built-in caching solution for performance optimization
170
171// Route modules
172app.route("/api", api); // JSON API endpoints
173app.route("/tasks", tasks); // Notion webhook handlers
174app.route("/demo", demo); // Demo page serving
175```
176
177#### API Routes (`/api`)
178
179Serve JSON data and handle CRUD operations for demo management, cobrowsing status, and user interactions.
241```typescript
242const notion = new Client({
243  auth: Deno.env.get("NOTION_API_KEY"),
244});
245
249Required environment variables:
250
251- `NOTION_API_KEY`: Notion integration token
252- `GLANCE_DEMOS_DB_ID`: Notion database ID for demo pages
253- `GLANCE_INTERACTIONS_DB_ID`: Notion database ID for interaction tracking
289Different route areas serve specific purposes:
290
291- `/api/*`: JSON data endpoints for frontend consumption
292- `/demo/*`: Personalized demo page serving with data injection
293- `/tasks/*`: Notion webhook processing and database updates

7### Task endpoints use /controllers to get and save data
8
9In order to keep the API easy to look and work with, the routes in /tasks handle routing but do not get data from or save data to Notion. The functions that connect to Notion live in the /controllers directory, and are _called_ from the endpoints in /tasks.

11### Naming convention for routes and controllers
