Can someone help make this 2.0 extension work in 3.0?

Hello. I am trying to make this extension work in Scratch 3.0, using a link that loads Scratch 3 with custom extensions. That being said, the problem is that this is a 2.0 extension, but it needs to be 3.0. The only thing I could find online was a converter, which sadly didn't work for me. Any and all help is appreciated!

Since the Scratch extensions specification hasn't been finalized yet, there are two types of extensions in Scratch.

All the extensions in vanilla Scratch are “team” extensions, so they don't run in a worker and thus have access to localStorage. However, it requires modding.

Scratch also has “unofficial” extensions that run in a web worker; extensions loaded in my mod are unofficial extensions, so because they're in a web worker, they don't get access to some APIs like localStorage. However, they do have access to IndexedDB, and localForage, a library which uses IndexedDB, has a simplified localStorage-like API, and it's possible you could `importScripts` it

Nonetheless

Interesting.

So, if I understand correctly, it IS possible to get the localStorage to work, but I'd have to mod it… I'm fine doing that, but the problem is that I have a Windows PC, and that page looked very much like a Linux tutorial. So how should I go about getting a modded version of Scratch 3 that loads your *helpfully provided* version of the localStorage extension on Windows?

Speaking of which, thanks so much!

Actually, potential fix– if I was loading the extension via your HTML tool, would that work?

I'm afraid you have made a grave mistake. See https://ipfs.io/ipfs/Qmbdm26X1z1WsyTYry9bvKP988LekkugfkjLBPheT9rhZ6/2020-05-15_14-01-53.gif

@Sheep_maker Okay, completely unrelated, but I have a new question: would it be possible to have a mod just like the localStorage one, except the variables are online and hosted to a server?
