Examples

# Define and use golem_options
if (interactive()) {
  # 1. Pass parameters directly to `run_app`

  run_app(

    content = "something"
  )

  # 2. Get the values
  # 2.1 from the UI side

  h1(get_golem_options("title"))

  # 2.2 from the server-side

  output$param <- renderPrint({
    paste("param content = ", get_golem_options("content"))
  })

  output$param_full <- renderPrint({
    get_golem_options() # list of all golem options as a list.
  })

  # 3. If needed, to set default value, edit `run_app` like this :

  content = "that",
  ...

      app = shinyApp(
        ui = app_ui,
        server = app_server
      ),
      golem_opts = list(
        title = title,
