clipboard.js is a super light
javascript framework, which provides copy-to-clipboard functionality
using HTML5. The simple rclipboard
R 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
, for Shiny
R applications.
While rclipButton
and rclipLink
will work
in applications that use native shiny
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
<- bslib::page_fluid(
ui
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
<- function(input, output) {
server
# Add clipboard buttons
$clip <- renderUI({
outputrclipButton(
inputId = "clipbtn",
label = "rclipButton Copy",
clipText = input$copytext,
icon = icon("clipboard"),
tooltip = "Click me... I dare you!",
placement = "top",
options = list(delay = list(show = 800, hide = 100), trigger = "hover")
)
})
}
shinyApp(ui = ui, server = server)
