Simon Willison Builds an OPFS + Pyodide Test Harness to Probe Persistent Browser SQLite Editing
Willison published a June 23 playground that tests whether Datasette Lite can edit persistent SQLite files via the browser's Origin Private File System (OPFS) API across different browsers. It's an experimental probe into making client-side data tools genuinely durable rather than ephemeral per-session. Useful reference for anyone shipping WASM/Pyodide apps that need real local persistence beyond IndexedDB hacks.
