Timer

Creates a reactive timer with the given interval. A reactive timer is like a reactive value, except reactive values are triggered when they are set, while reactive timers are triggered simply by the passage of time.

Usage
reactiveTimer(intervalMs = 1000)
Arguments
intervalMs
How often to fire, in milliseconds
Details

Reactive expressions and observers that want to be invalidated by the timer need to call the timer function that reactiveTimer returns, even if the current time value is not actually needed.

See invalidateLater as a safer and simpler alternative.

Value

  • A no-parameter function that can be called from a reactive context, in order to cause that context to be invalidated the next time the timer interval elapses. Calling the returned function also happens to yield the current time (as in Sys.time).
