timer-stopwatch

A stopwatch and countdown clock module for node.js, maintained.

Install

npm install timer-stopwatch

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);
	console.log(time.seconds); // number of seconds 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
timer.getState() // Return 0, 1 or 2 if the timer is respectively stopped, running or complete
timer.isStopped()
timer.isRunning()
timer.isComplete()

Properties

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