Non blocking asynchronous sleep, with watching condition.

The library has method:

• timeout - sleep time in milisecond,
• done - callback runned always after sleep.

• condition - condition function has checked on any sleep cycle. When condition is true, the sleep is done.
• timeout - max timeout to sleep.
• done - callback runned always after sleep.

• condition - condition function has checked on any sleep cycle. When condition is true, the sleep is done.
• options - advanced options for sleep.
  • full options example:

    var options = {
      sleep: 1000,
      interval: 10
    };

• done - callback runned always after sleep.

var sleep = require('sleep-async')();

sleep.sleep(5000, function(){
  stopTime = new Date().getTime();
  console.log('Difference: '+((stopTime-startTime)/1000)+' [s]');
});

sleep.sleepWithCondition(function(){
    return collection.length >= 10;
  },
  5000,
  function(){
    stopTime = new Date().getTime();
    console.log('Difference: '+((stopTime-startTime)/1000)+' [s]');
});

var options = {
  sleep: 5000,
  interval: 2500
};

sleep.sleepWithCondition(function(){
    return collection.length >= 10;
  },
  options,
  function(){
    stopTime = new Date().getTime();
    console.log('Difference: '+((stopTime-startTime)/1000)+' [s]');
  });
