standby

Easily create alerts, notifications, tooltips and loading screens in Shiny

Installation

You can install the development version of standby from GitHub with:

# install.packages("devtools")
devtools::install_github("rsquaredacademy/standby")

Usage

Loading Screens

To use spinners/loaders from standby in your Shiny application, include the following in the UI part of the app:

Include the dependencies using the appropriate use* functions (useSpinkit() in the below example).
Wrap the target output using corresponding rendering function (spinkit() in the below example).

Example

library(shiny)
library(standby)

ui <- fluidPage(

  standby::useSpinkit(), # include dependencies
  fluidRow(
    standby::spinkit(plotOutput("plot1")), # wrap output inside loader
    actionButton("render", "Render")
  )

)

server <- function(input, output, session) {

    output$plot1 <- renderPlot({
      input$render
      Sys.sleep(3)
      plot(cars)
    })

}

shinyApp(ui, server)

The below table displays the dependency and rendering functions along with references:

Index	Dependency	Render	Reference

Alerts and Notifications

To use alerts or notifications from buzz in your Shiny application, follow the below steps:

Include the corresponding rendering function in the Server part of the app (toast() in the below example).

Example

library(shiny)
library(standby)
ui <- fluidPage(
  useBootBox(), # include dependencies
  actionButton(inputId = "notify",
               label   = "Show Notification")
)
server <- function(input, output, session) {
  observeEvent(input$pnotify, {
    bootBox(class = "rubberBand") # display the alert
  })
}
shinyApp(ui, server)
