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:
158- **AI Image:** To inline generate an AI image use: `<img src="https://maxm-imggenurl.web.val.run/the-description-of-your-image" />`
159- **Storage:** DO NOT use the Deno KV module for storage
160- **Browser APIs:** DO NOT use the `alert()`, `prompt()`, or `confirm()` methods
161- **Weather Data:** Use open-meteo for weather data (doesn't require API keys) unless otherwise specified
162- **Error Debugging:** Add `<script src="https://esm.town/v/std/catch"></script>` to HTML to capture client-side errors
163- **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
164- **Environment Variables:** Use `Deno.env.get('keyname')` when you need to, but generally prefer APIs that don't require keys
165- **Imports:** Use `https://esm.sh` for npm and Deno dependencies to ensure compatibility on server and browser
166- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites
200### Backend (Hono) Best Practices
201
202- Hono is the recommended API framework
203- Main entry point should be `backend/index.ts`
204- Do NOT use Hono serveStatic middleware
225  });
226  ```
227- Create RESTful API routes for CRUD operations
228- Always include this snippet at the top-level Hono app to re-throwing errors to see full stack traces:
229  ```ts
262   - For files in the project, use `readFile` helpers
263
2645. **API Design:**
265   - `fetch` handler is the entry point for HTTP vals
266   - Run the Hono app with `export default app.fetch // This is the entry point for HTTP vals`
