In JohnCoene/waiter: Loading Screen for 'Shiny'

waiter

Loading screens for Shiny; programmatically show and hide partial or full page loading screens with spinners or loading bars, see the demo and the cheat sheet.

Introduction by Veerle

The Staff

The following staff members will help you keep your clients waiting:

• A waiter is ideal for a spinner
• The waitress and the hostess are great to show progress

Example

Simply place autoWaiter in your UI.

```r {highlight: [5]} library(shiny) library(waiter)

ui <- fluidPage( autoWaiter(), actionButton( "trigger", "Render" ), plotOutput("plot"), plotOutput("plot2") )

server <- function(input, output){ output$plot <- renderPlot({ input$trigger Sys.sleep(3) plot(cars) })

output$plot2 <- renderPlot({
    input$trigger
    Sys.sleep(5)
    plot(runif(100))
})

}

shinyApp(ui, server)
