How to

The Gist new Stopwatch([countDownMS], [options])

Basic timers

var Stopwatch = require('timer-stopwatch');
 
var timer = new Stopwatch(60000); // A new countdown timer with 60 seconds
var stopwatch = new Stopwatch(); // A new count up stopwatch. Starts at 0.

Event Methods

// Fires every 50ms by default. Change setting the 'refreshRateMS' options
timer.onTime(function(time) {
    console.log(time.ms); // number of milliseconds past (or remaining);
});
 
// Fires when the timer is done
timer.onDone(function(){
    console.log('Timer is complete');
});
 
// Fires when the timer is almost complete - default is 10 seconds remaining. Change with 'almostDoneMS' option
timer.onAlmostdone(function() {
    console.log('Timer is almost complete');
});
 
//These methods are chainable
timer.onTime(cb).onAlmostdone(cb).onDone(cb);
 

Timer Methods

timer.start();
timer.stop();
timer.startstop();        // Toggles the running state
timer.reset(countDownMS); // optional countDownMS to reset countdown to that many milliseconds

Properties

timer.ms;		// Number of milliseconds on the clock

Options

var options = {
    refreshRateMS: 10,		// How often the clock should be updated
    almostDoneMS: 10000, 	// When counting down - this event will fire with this many milliseconds remaining on the clock
}
 
var timer = new Stopwatch(60000, options);

Breaking Changes in v0.2
