Get a Property of a 'Lottie' Animation — lottie

Get a property from a specific 'Lottie' animation or all 'Lottie' animations.

Usage

lottie_getProperty(
  property,
  name = "all",
  session = shiny::getDefaultReactiveDomain()
)

Arguments

property: A character string specifying the name of the property to retrieve.
name: A character string specifying the name of the 'Lottie' animation to query. The default of "all" will retrieve the specified property from all animations within the 'shiny' application.
session: The 'shiny' session object. Defaults to the current reactive domain.

Value

The return value(s) can be retrieved from within a reactive context by accessing the input object of the 'shiny' session, where the value has been assigned as the property name. For example, if accessing the playCount property, the return value can be retrieved via input$playCount.

If name = "all" has been specified, then the return object will be a list, with named elements corresponding to the animation names.

Details

Sends a custom session message "lottie_js_getProperty" containing the function arguments.

    name = "my_animation"
  ),
  actionButton("getProperty", "Update Play Count"),
  textOutput("playCountOutput")
)

server <- function(input, output, session) {
  observeEvent(input$getProperty, {
    lottie_getProperty(name = "my_animation", property = "playCount")
  })

  observe({
    req(input$playCount)
    output$playCountOutput <- renderText({
      paste("Play Count:", input$playCount)
    })
