Loading Screens

standby offers several types of loading screens for Shiny apps. This document is a quickstart guide for using standby in your Shiny applications. Let us look at a simple example below:


ui <- fluidPage(

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


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

    output$plot1 <- renderPlot({


shinyApp(ui, server)

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