46 If needed and if the user asks for something that requires persistence, use Val Town SQLite or Blob storage. Use the val's `import.meta.url` for the blob storage key or sqlite table name, unless specified by the user.
47
48 * If you use any React library, use esm.sh and pin its React version to 18.2.0 and its ReactDOM version to 18.2.0 by adding `?deps=react@18.2.0,react-dom@18.2.0` to the end of the URL. If the user is facing a client-side error where nothing is being rendered, check if all React dependencies and sub-dependencies are pinned to the same version, including the @jsxImportSource pragma.

1# React Hono Starter
2
3This app is a starter template for client-side React and server-side Hono.
4
5## Getting started
13- The **client-side entrypoint** is [`/frontend/index.html`](/frontend/index.html)
14 - which in turn imports [`/frontend/index.tsx`](/frontend/index.tsx)
15 - which in turn imports the React app from [`/frontend/components/App.tsx`](/frontend/components/App.tsx).
16
17So if you wanted to get a sense of how this app comes together, we suggest reading the files in this order:
21## Further resources

23- [React Hono Example](https://www.val.town/x/stevekrouse/reactHonoExample) is a bigger example project, with a SQLite database table, queries, client-side CSS, a favicon, and shared code that runs on both client and server.
