online demo and api doc?

I've done some work on https://github.com/YarnSpinnerTool/YarnEditor and have been thinking of rewriting the thing, since it is using a bunch of really outdated libraries and the code is just full of doing stuff from scratch for no reason parts.

I like svelte and also need a library that would allow me to recreate the style of nodes that yarneditor uses. Be able to display node contents, but also summon a full node editor dialog when double clicking on a node.

Now do you think I can get that? How do I get straight line connections with arrows? Can I make custom nodes somehow with this? Can I customize what happens when you double click on a node? How flexible is the api?
