The articles section on shiny.rstudio.com has lots of great advice for Shiny developers. 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 →

Action buttons can be tricky to use in Shiny because they work differently than other widgets. Widgets like sliders and select boxes maintain a value that is easy to use in your code. But the value of an action button is arbitrary. What should you do with it? Did you know that you should almost always call the value of an action button from observeEvent() or eventReactive()? 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 →
