Scratchpad/test app for the WASMF/OPFS integration in a WORKER thread. This page requires that the sqlite3 API have been built with WASMFS support. If OPFS support is available then it "should" persist a database across reloads (watch the dev console output), otherwise it will not.

All stuff on this page happens in the dev console.
