Val Town Code SearchReturn to Val Town

10- **Furniture Focus**: Special features for tracking furniture links and discussions
11- **Val.town Integration**: Runs on Val.town for easy deployment and scheduling
12- **Periodic Updates**: Automatically fetches new messages on a schedule
13
14## Use Cases
58   ```
59
606. Test the DM fetching process
61   ```
62   node val-town-cron.js
84   - Add the same environment variables from your `.env` file
85
865. Set up a scheduled task on Val.town for periodic DM fetching
87   - Create a new scheduled task using the Val.town dashboard
88   - Use the `discordDMBotCron` function
108
109- `GET /health`: Health check endpoint
110- `POST /api/fetch-dms`: Manually trigger DM fetching
111- `POST /api/process-links`: Manually trigger link processing
112- `POST /api/query`: Submit a query about your message history

239    
240    // Inject data to avoid extra round-trips
241    const initialData = await fetchInitialData();
242    const dataScript = `<script>
243      window.__INITIAL_DATA__ = ${JSON.stringify(initialData)};
286
2875. **API Design:**
288   - `fetch` handler is the entry point for HTTP vals
289   - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`

15- **AI Integration**: Leverages Anthropic's Claude API for analysis
16- **Discord Integration**:
17  - Bot token for fetching messages
18  - Slash commands for user interactions
19  - Webhook endpoint for Discord interactions
502. Copy the contents of the backend directory
513. Set up the required environment variables
524. Create a cron schedule for periodically fetching messages and processing links
