A recent article by Dean Attali demonstrates how to save data from a Shiny app to persistent storage structures, like local files, servers, databases, and more. When you do this, your data remains after the app has closed, which opens new doors for data collection and analysis. Read Dean’s article and more at shiny.rstudio.com/articles Read more →

The newest article at the Shiny Development Center explains how action buttons work, and it provides five useful patterns for working with action buttons. Read more →
