Thank you!
1. Nodes with custom logic, structure (inputs/outputs etc) and custom configuration editing are definitely possible.
But I assume you mean custom nodes as in nodes that render the data passing through them, like in litegraph.js, right?
If so, it's not possible, as IMO it's less of a value for "production" use-cases/application level layer. But if the community's interest will slide in that direction, I will consider going that route.
2. It can be used as a library, either Node.js (via an npm package) or the browser (using a custom webpack loader)
- Can we make custom nodes in this (e.g. a node which to display images)?
- Can it be used like a client side js library (like litegraph)? or does it have to be used in IDE and its more like an IDE enhancement?
Looking back at the page and examples again, is it not the usecase this is for?
