13- Generate code in TypeScript or TSX
14- Add appropriate TypeScript types and interfaces for all data structures
15- Prefer official SDKs or libraries than writing API calls directly
16- Ask the user to supply API or library documentation if you are at all unsure about it
17- **Never bake in secrets into the code** - always use environment variables
18- Include comments explaining complex logic (avoid commenting obvious operations)
23### 1. HTTP Trigger
24
25- Create web APIs and endpoints
26- Handle HTTP requests and responses
27- Example structure:
173However, it's *extremely importing* to note that `parseProject` and other Standard Library utilities ONLY RUN ON THE SERVER.
174If you need access to this data on the client, run it in the server and pass it to the client by splicing it into the HTML page
175or by making an API request for it.
176
177## Val Town Platform Specifics
181- **AI Image:** To inline generate an AI image use: `<img src="https://maxm-imggenurl.web.val.run/the-description-of-your-image" />`
182- **Storage:** DO NOT use the Deno KV module for storage
183- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods
184- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified
185- **View Source:** Add a view source link by importing & using `import.meta.url.replace("ems.sh", "val.town)"` (or passing this data to the client) and include `target="_top"` attribute
186- **Error Debugging:** Add `<script src="https://esm.town/v/std/catch"></script>` to HTML to capture client-side errors
187- **Error Handling:** Only use try...catch when there's a clear local resolution; Avoid catches that merely log or return 500s. Let errors bubble up with full context
188- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but generally prefer APIs that don't require keys
189- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure compatibility on server and browser
190- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites
224### Backend (Hono) Best Practices
225
226- Hono is the recommended API framework
227- Main entry point should be `backend/index.ts`
228- **Static asset serving:** Use the utility functions to read and serve project files:
248  });
249  ```
250- Create RESTful API routes for CRUD operations
251- Always include this snippet at the top-level Hono app to re-throwing errors to see full stack traces:
252  ```ts
285   - For files in the project, use `readFile` helpers
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`

17- `DISCORD_MONITORED_CHANNELS`: Comma-separated channel IDs to monitor (right-click channel → Copy ID)
18  - Example: `1327384540187983926,1327384540187983927`
19- `LINEAR_API_KEY`: Your Linear API key
20  - Go to Linear Settings → API → Personal API keys → Create key
21- `LINEAR_TEAM_ID`: Your Linear team UUID, this is NOT the 3 letter `Team Identifier` found in issue IDs
22  - On any Linear page, type `CMD+K` to pull up the quick menu + enter `Dev: Copy model UUID` to copy your UUID
