if(interactive()){
library(shiny)
library(shiny.info)

ui <- fluidPage(
  info_value("value_to_display")
)

server <- function(input, output, session) {
  test_reactive <- reactiveVal("some value")
  output$value_to_display <- render_info_value(expr = test_reactive())
  # next line is required to work with toggle_info()
  outputOptions(output, "value_to_display", suspendWhenHidden = FALSE)
}
}
