In episode 12 of the Shiny Developer Series, we begin a multi-part series with RStudio software engineer on the Shiny team Barret Schloerke! In part 1 we learn more about Barret’s journey to the Shiny team and take a deep dive into the very powerful reactlog framework to help users shed some light on what can be a confusing world of reactivity in their applications. Barret leads us through interactive demonstrations of reactlog applied to simple and complex applications to pinpoint various issues on reactive logic and the flow of information from inputs to outputs.
