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`.

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.

Every Val Town account comes with a free SQLite database, hosted on [Turso](https://turso.tech/). 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. It's left in so that users who fork this project will have the migration run correctly.\n\nSQLite has much more limited support for altering existing tables as compared to other databases. Often it's easier to create new tables with the schema you want, and then copy the data over. Happily LLMs are quite good at those sort of database operations, but please reach out in the [Val Town Discord](https://discord.com/invite/dHv45uN5RY) if you need help.\n\n## Queries\n\nThe queries file is where running the migrations happen in this app. It'd also be reasonable for that to happen in index.ts, or as is said above, for that line to be commented out, and only run when actual changes are made to your database schema.\n\nThe queries file exports functions to get and write data.
