rclipboard: clipboard.js for R/Shiny applications

clipboard.js is a super light javascript framework, which provides copy-to-clipboard functionality using HTML5. The simple rclipboardR package is simple and leverages clipboard.js functionality to provide a reactive copy-to-clipboard UI button component, called rclipButton, and a reactive copy-to-clipboard UI link component, called rclipLink, forShiny R applications.

While rclipButton and rclipLink will work in applications that use nativeshiny UI constructors, the code below illustrates a marginally more complex example in which a tooltip is displayed when hovering on top of the button thanks to the use of UI constructors from the bslib package.

library(shiny) library(bslib) library(rclipboard)

The UI

ui <- bslib::page_fluid(

rclipboardSetup(),

Add a text input

textInput("copytext", "Copy this:", "Zlika!"),

UI ouputs for the copy-to-clipboard buttons

uiOutput("clip"),

A text input for testing the clipboard content.

textInput("paste", "Paste here:")

)

The server

server <- function(input, output) {

Add clipboard buttons

output$clip <- renderUI({ rclipButton( inputId = "clipbtn", label = "rclipButton Copy", clipText = input$copytext, icon = icon("clipboard"), tooltip = "Click me... I dare you!", placement = "top", options = list(delay = list(show = 800, hide = 100), trigger = "hover") ) })

}
