I'm trying to implement a remote file tree viewer like this.

The key requirement is laziness. I want to make it so that the initial remote request only asks for one level. Further requests for listing files in the sub-folders will only be sent when the triangle is clicked.

I read through https://book.fulcrologic.com/#_recursive_queries but still have questions. How would you design the stated component?

I'd imagine the initial request be something like this:

[:dir/id :dir/name
 {:dir/files [:file/id :file/name]}
 {:dir/sub-dirs [:dir/id :dir/name]}]

But how would you write the :onClick function for the triangle?

Another unrelated question: can I have a UI state :ui/xxx that is not shared between different views on the same entity? I don't want to use separate ids for them because I want the remote props be linked. This is very common requirement for e.g. implementing checkboxes on a tree view that have one node appearing at multiple locations.

You can always use component-local state if you want a component-local value that is not part of the actual state in the fulcr odb

on the laziness: your recursive query would just state 1 instead of …, and then you’d pull the next level from the node that is expanded

How do I pass props to a component that I'm routing to?
