stifle

stifle

Wrap a function, so it is only called (at most) once every X milliseconds.

    var stifle = require('stifle')

    // A silly little clock
    function tellTime () {
      console.log('The time is now ' + new Date())
    }

    // Only show the time once per second
    var secondHand = stifle(tellTime, 1000)

    // Call it like crazy, but it will only fire once per second
    var interval = setInterval(secondHand, 10)

Cancellation

The wrapped function comes with a cancel method to kill and pending future invocations -- useful for shutting it down when a page or component is being unloaded.

    // Stop calling the secondHand
    clearInterval(interval)

    // Cancel pending calls, or else it will fire one more time
    secondHand.cancel()

No Extras

To keep it fast and simple, stifle does not support:

• passing parameters
• returning values
• recursive invocation
• "flushing" pending invocations
• leading/trailing options
