This is the HTML page that is returned at the root from `/backend/index.ts`.\n\nThis HTML file imports `/frontend/style.css` from `/public/style.css` and `/frontend/favicon.svg` from `/frontend/favicon.svg`. Everything in `/frontend/` is mapped to `/public` by `/backend/index.ts`. This is just a convention. You could import & serve everything out of the same folder name.\n\nThis HTML file has a `

`, which is where we mount the React app.\n\nThis HTML file imports `/frontend/index.tsx` from `/public/index.tsx`, which is the **entrypoint** for all frontend JavaScript, including all the React. It is not a problem that it imports a file with a `.tsx` extension becaues browsers ignore file extensions. They only pay attention to content-types, which is great, because all these files will be returned as transpiled JS with the appropriate JS content type by [stevekrouse/utils/serve-public](https://www.val.town/x/stevekrouse/utils/branch/main/code/serve-public/README.md).)\n\n## `index.tsx`\n\nThis file is the **entrypoint** for frontend JavaScript. It imports the React app from `/frontend/components/App.tsx` and mounts it on `

`.\n\nIt also looks for *bootstrapped* JSON data at `window.__INITIAL_DATA`, and passes that only to the ``.\n\n## `favicon.svg`\n\nAs of this writing Val Town only supports text files, which is why the favicon is an SVG and not an .ico or any other binary image format. If you need binary file storage, check out [Blob Storage](https://docs.val.town/std/blob/).\n\n## `components/`\n\nThis directory is where the React components are stored.

This folder is broken up into two files:\n\n* `migrations.ts` - code to set up the database tables the app needs\n* `queries.ts` - functions to run queries against those tables, which are imported and used in the main Hono server in `/backend/index.ts`\n\n## Migrations\n\nIn `backend/database/migrations.ts`, this app creates a new SQLite table `reactHonoStarter_messages` to store messages. \n\nThis \"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.
