Session Summary:

Multilingual shiny apps are not straightforward to build. Translation affects almost every single aspect of an app. Although there are a few packages designed to automate the translation process, they tend to only work for the most widely spoken languages.

Using a bilingual English-Welsh shiny app we developed to present public health data as a case study, this talk will discuss:

  • how we built a multilingual shiny app;
  • how translation affected design decisions;
  • how we overcame the main issues faced;
  • and most importantly, what we'd do differently next time.

By the end of this talk, you will have a better understanding of how to translate your Shiny app to help you to share your app with a much wider audience.
