# TeaQL Browser SQLite Playground

This playground runs entirely inside your browser:

- SQLite runs as WebAssembly in a dedicated Web Worker.
- Generated TeaQL Q APIs execute against that browser-local database.
- Demo records are created through audited generated mutation APIs.
- Memory mode resets on refresh and gives every visitor the same starting point.
- Optional OPFS mode persists data within the current browser origin when the host supports it.
- Reset drops the local schema, recreates it, and seeds the demo again.

There is no application backend and no server-side business database. The
Space only serves static HTML, JavaScript, CSS, and WASM assets. Query and
mutation data remain in the visitor's browser.

The complete source and executable browser smoke test are maintained in the
[`teaql-ts` browser-sqlite example](https://github.com/teaql/teaql-ts/tree/main/examples/browser-sqlite).
