OK, this is very weird. Without any the other changes, merely renaming useIsVisible.jsx to useIsVisible.tsx totally breaks the build of the Paragon docs site (in dev mode, if I restart it, I cannot access the site). But the error is very obscure.

nit/question: should both refs get the same type with HTMLDivElement, given both refs are applied to divs below?

curious/suggestion: would it improve readability/understandability of these types if these function args and the return data structure were abstracted into an interface? E.g., something like the following:

interface HandleEnterOptions { event: KeyboardEvent; currentIndex: number; activeElement: HTMLElement; } function handleEnter({ event, currentIndex, activeElement }: HandleEnterOptions) { ... }

Similar question for handleArrowKey below

[clarification] Will this sentinelRef always be applied to a Div element? Might it be used with non-div elements, too?

@bradenmacdonald just checking in to see if this is still in progress!

bradenmacdonald · 2024-12-09T22:29:40Z

@mphilbrick211 Thanks for the reminder. I lost momentum on this but now that I have @adamstankiewicz's feedback I would like to pick it up again soon!

Update: I tried to move this forward, but I'm blocked on some strange webpack bug where it is confusing useToggle.mdx and useToggle.tsx, returning the MDX content when I import the TypeScript file. I believe the only way to fix it is likely upgrading gatsby.

I pulled the branch and got the docs site to build/run locally with a less than ideal workaround. I added Doc to the filenames of all the .mdx files in the hooks directory. Unfortunately that led to the url for those pages also having doc in them (example: http://localhost:8000/components/hooks/usetoggledoc/)

I'll do a little more digging to see if I can come up with a better option.
