Upload inserted images to a backend

[PaddiM8]

It would be nice to have some way to automatically upload inserted images to a backend and then use the returned URL, if it isn't possible already. Right now it doesn't seem to be possible to paste some types of images as well (when the clipboard data doesn't contain an external url?).

Maybe it could simply be handled by some event with a callback?

Ok, I might have a solution that fixes the problem where some images can't be pasted, while also making it possible to replace the URL of pasted images.

In ImagePlugin, I dispatch an insert event for INSERT_IMAGE_COMMAND, that contains the image's src and an ImageNode. I also added a registerCommand call for PASTE_COMMAND, which converts pasted images to base64 in order to make it possible to paste any kind of copied image, and then the same things are done as for INSERT_IMAGE_COMMAND.

This is probably what I'm going to use for myself at least, but I could also make PR if anything here is relevant for the official svelte-lexical. Will also think a bit more about the structure.

Hi @PaddiM8 ,

Perhaps this could be added to one of the demos, instead of the svelte-lexical core. Is your code in an open source repo? Can I have a look please?

Thanks.

Hi. I made modifications to the core package in my fork to make this possible. It's available here https://github.com/PaddiM8/svelte-lexical/tree/fix-image-paste
