Create a logging observer for a reactive Shiny input — regulog_observer • regulog

Wraps shiny::observeEvent() to log an action whenever eventExpr fires. Reduces boilerplate when many UI events need to be audited.

regulog_observer(log, session, eventExpr, action, object, reason, ...)

Arguments

log: A regulog object.
session: The Shiny session object.
eventExpr: Reactive expression to observe.
action: Character. Action label.
object: Character or reactive. The object acted upon.
reason: Character or reactive. Business justification.
...: Additional arguments passed to log_action().

Value

A Shiny observer (invisibly).

Examples

if (FALSE) { # \dontrun{
regulog_observer(log, session,
  eventExpr = input$approve,
  action    = "approved",
  object    = reactive(input$selected_dataset),
  reason    = reactive(input$reason_text)
)
} # }
