Episode 22: A fresh coat of Shiny theming with Carson Sievert

Earlier this year at RStudio Global, a lot of excitement among the Shiny enthusiasts centered on the brand new bslib and thematic packages for radically changing the style of typical Shiny app user interfaces. I am thrilled to get the inside story on this amazing development with the brilliant author, RStudio software engineer Carson Sievert! In this episode you will hear Carson’s recommendations on getting started with bslib for both Shiny applications and even R-Markdown documents, why SASS (no, not that one) rules empower a Shiny developer to make sweeping changes in CSS, as well as the major milestone release of shinymeta, a package that directly addresses a huge need for traceable and reproducible analyses from Shiny apps in many industries such as life sciences. I hope you enjoy this episode and don’t forget to subscribe to our channel so you can be first to know when future episodes are available!
