Trigger re-calculation of visibility from outside the component

Hi, I’ve got a scenario where unmounting components brings others into view. As neither a scroll nor resize event is fired so no computation is done. My current thinking is to have a prop be passed in (say detectOnChange) and when that prop changes we trigger a re-calculation of visibility.

In my use case, I’ve got a series of accordions. Inside those accordion are visibility tracked components. Closing one of those accordions brings other components into view. What I’m doing is tracking the state of open accordions and passing the count of open accordions to the tracked component. Then on change I can fire the isComponentVisible function.

What are your thoughts?

Thanks, Tom

Yeah, it looks interesting. I don’t see a problem with both solutions co-existing. I’ll put together a PR with what I was suggesting, don’t hold back as it’s a little out there!

Hey,

I think that it can be a good idea to extend PureComponent. At least we can try and see if there is any performance impact.

I also like the idea to add a third event like https://github.com/Stanko/window-scroll-manager.
