Shiny Applications Internationalization

It provides easy internationalization of Shiny applications. It can be used as standalone translation package to translate reports, interactive visualizations or graphical elements as well.

Shiny applications internationalisation made easy!

Actually, you can use shiny.i18n as a standalone R package - shiny app is just a perfect usecase example.

Using it is very simple: just prepare your translation files in one of the supported formats, read them into your app using user-friendly shiny.i18n interface and surround your expressions to translate by a translator tag. Thanks to that your app will remain neat and readible.
