I've been using Shiny for about 3 years now, and have designed some dashboards that have impressed probably only me and a few of the cybersecurity analysts I work with.
Nonetheless, one of the concepts in Shiny that has really been tugging on my mind lately is reactive programming, and namely the thing doing the tugging is my very remedial - but evolving - understanding of AWS Lambda and triggers & handlers more generally.
I don't want to post a lot of code because a) my current use cases are mostly work-related b) I think what I'm trying to discuss here more broadly is the following idea:
Can reactive programming and objects be used to poll a some generic resource with some frequency - ie, using invalidateLater - and thus be used as triggers for AWS Lambda jobs?
