Multiplayer support

[jogibear9988]

Have you already thought about Multiplayer support in grapejs (or has it)?
I'm think of implementing in my designer (https://github.com/node-projects/web-component-designer), but it's a hard task (I think), cause also of the posibillity to edit the source code.

Found this interesting blog post about support in figma: https://www.figma.com/de-de/blog/how-figmas-multiplayer-technology-works/

Wanted to know, what are your thoughts about this.

For sure we'll need it, I actually built already the multiplayer support for another product a few years back (that Figma article was actually my main reference 😅).

The big problem is how we manage the state and the current data structure in GrapesJS that makes this implementation harder but it should definitely be part of our roadmap.

I'm not yet really sure on how to implement multiplayer . For example, in my designer you can edit in design mode, source code or split view. If you edit in Source Code, I reload the whole designer, cause everything could be changed. How should I now solve a conflict if someone moved an elment in design view at the same time?
Have you Ideas for this?

You have to find a way to diff the changes instead of reloading the whole designer

you can achieve this, in any of the following ways:
WebRTC
ServerSentEvent (SSE)
interval-based checking (for example each 10s or more(can be configured per/view or per project))
