shinyglide

shinyglide is an R package which provides carousel-like or assistant-like components to shiny applications, thanks to the Glide JavaScript library.

It allows to create this sort of app (live example) :

Or can be integrated into an existing app to create an “assistant-like” interface (live example):

Features

• Responsive, navigation by mouse, keyboard, swiping
• Controls are completely customizable (live example)
• Next and Back controls can be disabled until an input condition is met (same syntax as shiny::conditionalPanel)
• “Screens” can be generated or hidden depending on user inputs. Loading time are taken into accounts (disabled Next button and customizable animation)
• Integration with Shiny modal dialogs (live example)
• Multiple glides per app (live example)

Installation

You can install the stable version with :

install.packages("shinyglide")

And the development version with :

remotes::install_github("juba/shinyglide")

Usage

A shinyglide component is created with the glide() function. This component is then divided intro screens with the screen() function.

Here is the code of a very basic app (live example):

library(shiny)
library(shinyglide)

ui <- fixedPage(style = "max-width: 500px;",
  titlePanel("Simple shinyglide app"),

  glide(
    height = "350px",
    screen(
      p("This is a very simple shinyglide application."),
      p("Please click on Next to go to the next screen.")
    ),
    screen(
      p("Please choose a value."),
      numericInput("n", "n", value = 10, min = 10)
    ),
    screen(
      p("And here is the result."),
      plotOutput("plot")
    )
  )
)


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

  output$plot <- renderPlot({
    hist(
      rnorm(input$n),
      main = paste("n =", input$n),
      xlab = ""
    )
  })

}

shinyApp(ui, server)

Development notes

This package uses packer to manage JavaScript source code and dependencies. If you want to modify it, you’ll need a working installation of Node.js.

After cloning this repository, run the following in a terminal at the project root :

npm install

Then, if you modify the JavaScript code in srcjs, you’ll have to run the following command to bundle and update the widget JavaScript code :

packer::bundle_dev()

If you want to ship a minimized production version, use :

packer::bundle_prod()
