Add cookies to an existing shiny ui

Wrap a shiny ui in this function in order to add cookie-handling functionality. The ui can be defined in any format compatible with shiny, using functions such as shiny::fluidPage(), shiny::bootstrapPage(), shiny::htmlTemplate(), or a raw HTML string.

Usage

add_cookie_handlers(ui)

Arguments

ui

A 0- or 1-argument function defining the ui of a shiny app, or a shiny::tagList().

Value

An object with the same signature as the input ui, but with the dependencies needed to handle cookies. If ui is a shiny::tagList(), a shiny::tagList() will be returned; if ui is a function, a function will be returned.
