Can't do async data migrations in the sync upgrade function about idb HOT 7 CLOSED

That's amazing, thanks for your help!

Put async before upgrade?

from idb.

I assume upgrade is not awaited, so if there are multiple migrations and it takes a bit of time, then the database object could be put to use in application code while the store is in some intermediate state.

It follows usual transaction rules https://github.com/jakearchibald/idb#transaction-lifetime

Sorry if I'm missing your point, but I want to be sure the upgrade is complete when the openDB promise resolves.

const db = await openDB<AppDb>("appData", currentVersion, {
      async upgrade(db, oldVersion, newVersion, transaction) {
        // Do a ton of stuff
      },
     ...
})
const allItems = await db.getAll('things') // Is the upgrade certainly done by now?

Yep, that's how it works

No problem! The lifetime of IDB transitions is pretty weird, unfortunately I can't really change that 😄
