Today we’re introducing App Stories to the Shiny website. If you’ve spent any time learning about Shiny, there’s a good chance you’ve already seen our Shiny User Showcase. These are applications that Shiny users around the world have allowed us to share, and it’s an excellent place to get ideas about what you can do with Shiny.

It’s very easy to accidentally add trailing commas when you’re writing and debugging a Shiny application. Read more →
