IDBBatchAtomicVFS error: `TypeError: Cannot read properties of null (reading 'fileSize')` about wa-sqlite HOT 4 CLOSED

For full reproducibility, you can checkout this branch of my code (thanhnguyen2187/crypta#28), then do yarn install, yarn dev, and look at the console log.

from wa-sqlite.

Based on the filename in your stack trace, I suspect you're using the non-Asyncify build (wa-sqlite.{mjs,wasm}). IDBBatchAtomicVFS requires the Asyncify build (wa-sqlite-async.{mjs,wasm}).

Oh I see. That really makes sense. I changed the importing to wa-sqlite-async.mjs and it worked. Many thanks for your help!

Maybe a document on how to use the example VFSs would be really helpful. What do you think?

There is this entry in the FAQ, and sample application code under demo/. It might be good to add a hello-async demo.
