Busy indicator for shiny apps

library(shinybusy)

{shinybusy} allow to add global indicators to a {shiny} application to show the user that application is busy (something is happening server-side). There is three main type of indicators :

Automatic indicators

The indicator will be displayed each time a calculation take more than the timeout defined (default to 1000ms), you don’t have to intervene in the server.

Three indicators are available :

# Add in UI
add_busy_spinner(spin = "fading-circle")

add_busy_bar(color = "red", height = "8px")

# Add in UI
add_busy_gif(
  src = "https://jeroen.github.io/images/banana.gif",
  height = 70, width = 70
)

Manual indicators

The same types of indicators are available than for automatic indicators, but this time functions starts with use_* and you have to explicitly trigger the indicator server-side.

# in UI
use_busy_spinner(spin = "fading-circle")

# in server
show_spinner() # show the spinner
hide_spinner() # hide the spinner
# in UI
use_busy_bar(color = "#01DF01", height = "15px")

# in server
update_busy_bar(0) # update with the desire value [0-100], 100 hide the bar
# in UI
use_busy_gif(
  src = "https://jeroen.github.io/images/banana.gif",
  height = 70, width = 70
)

# in server
