[Bug]: Multiple usage of useEditor (react) do not respect different extension usages per instance

[creatyvtype]

Which packages did you experience the bug in?

react

What Tiptap version are you using?

2.1.16

What’s the bug you are facing?

I have this sandbox to demonstrate my issue.

I am creating a react component wrapper for the usage of useEditor to make consistent API and UI among my team. When using 2 of these at the same time, I discovered that once an extension is registered on one instance, it would be applied to another that did NOT register it. Is there a fix for this? Any way around it?

I actually discovered this while testing a headless version with jest. One would think that between tests that it would not preserve the registered extension in a new test with a new instance, and yet it does.

What browser are you using?

Chrome

What did you expect to happen?

Each instance should have completely separate extensions.

It looks like you're mutating original coreExtensions array inside normalizeExtensions. So Bold extension is added multiple times. Try to do a shallow copy before mutating.

// const extensions: AnyExtension[] = coreExtensions;
const extensions: AnyExtension[] = [...coreExtensions];
toolbarOptions.forEach((opt) => {
  if (opt.tiptapExtension) {
    extensions.push(opt.tiptapExtension);
  }
});
return extensions;

After making this change it works for me as expected.

@romansp thank you! That 100% worked. Closing this.
