Hello dear developers. I have a very serious problem with the my extension
I'm trying to migrate from manifest version2 to manifest version3
I have not been able to solve the following problem:
How to migrate user data from indexedDB to storage API (to work with service worker)?
At the moment I don't see any solution for this.
Could you please point me to the information on how to solve this.

Thank you!

Are you implying that indexedDB does not work in service workers? Because it should.

Thanks for answering!
I'm currently (manifest v2) using an indexeddb in a background script.
And this database is not available after the migration (manifest v3) to the service worker. Isn't that how it should be?

indexeddb is available on the page itself where the content script "lives", but I can not access the indexeddb that was on the background script.
Maybe I'm doing something wrong.

IndexedDB is available in service workers, so I guess your code is using the ancient cross-browser method to access the API via `window`. Simply call indexedDB.open directly without any prefixes.

May be that you cannot view the indexeddb in Devtools when you're inspecting the service workers?

I would like to clarify one more detail.
My indexed Database (which was in the background page at manifest v2 held data.
Is there a way to access this indexed database from the service worker (after migrating to the v3 manifest)?

After the migration, I don't see my indexed database.

Your code in the service worker can access it directly: indexedDB.open()

To inspect IndexedDB visually in devtools, open any normal page of your extension like the popup, then use its devtools.
