cranwhales

cranwhales is a Shiny example application that demonstrates how to convert synchronous (traditional) Shiny apps to asynchronous ones. It visualizes download data from RStudio’s CRAN mirrors for any given day, with a focus on identifying and analyzing the top downloaders.

This package is valuable for learning asynchronous programming patterns in R and Shiny by providing both synchronous and asynchronous implementations of the same application. It solves the problem of understanding how to make Shiny apps more responsive and efficient when dealing with time-consuming operations. The app includes practical examples of data visualization and interactive filtering for CRAN download patterns.
