12## Serving assets to the frontend
13
14This backend HTTP server is responsible for serving all static assets to the browser to render the app, including HTML, JavaScript (including all client-side React), CSS, and even the favicon SVG.
15
16In a normal server environment, you would likely use a middleware [like this one](https://hono.dev/docs/getting-started/nodejs#serve-static-files) to serve static files. Some frameworks or deployment platforms automatically make any content inside a `public/` folder public. 
26## CRUD API Routes
27
28This app has two CRUD API routes: for reading and inserting into the messages table. They both speak JSON, which is standard. They import their functions from `/backend/database/queries.ts`. These routes are called from the React app to refresh and update data.
29
30## Errors

8## Migrations
9
10In `backend/database/migrations.ts`, this app creates a new SQLite table `reactHonoStarter_messages` to store messages. 
11
12This "migration" runs once on every app startup because it's imported in `index.ts`. You can comment this line out for a slight (30ms) performance improvement on cold starts. It's left in so that users who fork this project will have the migration run correctly.

155- Current health goals and any medication reminders needed?
156
157Your goal is to collect this information naturally through conversation and store it as memories (as undated memories). Once you've gathered sufficient background information, you can conclude the intake process and transition to normal reactive chat.
158
159If the conversation is already past the intake stage, then analyze the message content and think about which memories might be worth creating based on the information provided.

199- **Storage Strategy:** Only use backend storage if explicitly required; prefer simple static client-side sites
200- For persistence, use Val Town SQLite or Blob storage with `import.meta.url` for keys/table names
201- **React Configuration:** When using React libraries, pin versions with `?deps=react@18.2.0,react-dom@18.2.0` and include the `@jsxImportSource` pragma
202- When facing client-side render issues, check if all React dependencies are pinned to the same version
203- **Styling:** Default to using TailwindCSS via `<script src="https://cdn.twind.style" crossorigin></script>` unless otherwise specified
204
262
263### Frontend Best Practices
264- Structure as a standard client-side React app
265- Use SVG for favicons (Val Town only supports text files)
266- Separate components into individual files
267- Access bootstrapped data from `window.__INITIAL_DATA__`
268- Use React 18.2.0 consistently in all imports and the `@jsxImportSource` pragma
269- Follow the React component pattern from the example project
270- Handle API calls properly with proper error catching
271
289   - Always run table creation before querying
290
2913. **React Configuration:**
292   - All React dependencies must be pinned to 18.2.0
293   - Always include `@jsxImportSource https://esm.sh/react@18.2.0` at the top of React files
294   - Rendering issues often come from mismatched React versions
295
2964. **File Handling:**
