Hi team, I have a question related to integration. As I observed earlier, without tiptap, you use beforeInputPlugin when creating the editor (I tried to figure it out, but I didn't fully understand its essence).

As I understand it, this plugin is not needed for integration with tiptap?

[smoores-dev]

@shiz-ceo the beforeInputPlugin is pretty crucial to having a React-based contenteditable implementation. Both the plain <ProseMirror> and the new <TiptapEditorView> components use it under the hood, but it's an implementation detail that clients don't need to know about or use directly. It's a view-only ProseMirror plugin, so it's added directly to the EditorView props by the library when we construct the EditorView.

There is also a reactKeys plugin, which is something that consumers need to add to their EditorState when working with the plain ProseMirror API. With the Tiptap integration, this is covered by the ReactProseMirror Tiptap extension exported in this branch

@smoores-dev Thanks for the answer! It turns out that clients will not be able to use the functionality associated with composition and `beforeInput'?

P.S. Of course, these are very specific events for plugins, but they can be used to support languages where an IME is required (F.E).

EDIT: Of course this plugin don't return true from this events, but there may be the same somewhere.

The beforeInputPlugin works with IME inputs/compositions (at least, it should). Composition start events are dispatched before beforeInput events, so we handle composition flows separately.

Are you seeing issues with IME inputs? They can vary dramatically across OSes and browsers. We try to test them consistently, but this project's developers all use non-IME inputs, so it's possible that we're not always testing correctly.

No, I don't use IME input too, but I was just curious if you had ever encountered conflicting situations with this plugin. Thank you for your help!
