Minimal Sqlite WASM example with persistent storage in OPFS and Async API

Important!

Serve content using following headers, otherwise won't work:

Cross-Origin-Embedder-Policy: require-corp
Cross-Origin-Opener-Policy: same-origin

For reason see "Achtung: COOP and COEP HTTP Headers" in: https://sqlite.org/wasm/doc/trunk/persistence.md#coop-coep

Run (Serve locally)

python3 server-with-headers.py

0. look up breaking API changes: https://sqlite.org/wasm/doc/trunk/api-changes.md
