IndexedDB does not exist in Zotero 7?

[Emiliano Heyns]

IndexedDB doesn't seem to be present in Zotero 7. Is this planned to be present in the release?

[XY Wong]

AFAIK, It's available in non-privileged windows and webworkers.

[Emiliano Heyns]

Ah OK, in Zotero 6 it was also available in chrome code. But good to know.

When I try

importScripts('resource://gre/modules/Sqlite.jsm')

in a chromeworker, I'm getting

ChromeUtils.import is not a function

any tips on how to load sqlite support (not for the zotero database) from a chromeworker?

I have a feeling that’s just not supported. You could proxy the specific functions that you need in the worker via messaging.

I'm trying to cut down on in-memory caches to use less memory. Any chance of indexeddb making a comeback?

[XY Wong]

Try `const { IndexedDB } = ChromeUtils.importESModule( "resource://gre/modules/IndexedDB.sys.mjs" );`

(I tried to IndexedDB.open and it works, so probably it would work)

[Emiliano Heyns]

Looks like I made a mistake earlier; indexedDB is defined in Zotero 7 ChromeWorker

[Emiliano Heyns]

This code doesn't work in the "Run Javascript" window though, I'm getting TypeError: ChromeUtils.importESModule is not a function

It works fine from the Run JavaScript window for me. Are you not on an fx115 build? (Check Zotero.platformMajorVersion.)

I was trying it in Zotero 6, sorry. Different question though: indexedDB (and associated entities IDBRequest, IDBTransaction, IDBDatabase, IDBObjectStore, IDBIndex, IDBCursor) are not available in the bootstrap context; I assume because they are traditionally tied to `window`, which the bootstrap doesn't have. But indexedDB is also available in workers, and those don't have a window either.
