Meet

Provides a way to start multiple tasks with a single callback when all are finished.

Install

npm install meet

Run tasks cuncurrently

var Meet = require("meet")
var meet = new Meet()

meet.start( function() {
	var done = this
	// do stuff
	done()
})

meet.start( function() {
	var done = this
	// do other stuff
	done()
})

meet.allDone( function() {
	// all tasks have completed
})

Run tasks sequentially

meet.queue( function() {
	var done = this
	// do something first 
	done()
})

meet.queue( function() {
	var done = this
	// do something after the first thing 
	done()
})

meet.allDone( function() {
	// all tasks have completed
})

Example

var Meet = require("meet")
var meet = new Meet()

// These tasks are "started". They run concurrently & finish in random order
function timeTask(t, id) {
	var done = this
	setTimeout(function() {
		console.log("time "+id+": "+t)
		done()
	}, t)
}
meet.start(timeTask, Math.random() * 6000, "a")
meet.start(timeTask, Math.random() * 6000, "b")
meet.start(timeTask, Math.random() * 6000, "c")
meet.start(timeTask, Math.random() * 6000, "d")

// These tasks are "queued".  They run sequentially in the order that they were queued
function queueTask(t, id) {
	var done = this
	setTimeout(function() {
		console.log("queue "+id+": "+t)
		done()
	}, t)
}
meet.queue(queueTask, Math.random() * 2000, "A")
meet.queue(queueTask, Math.random() * 2000, "B")
meet.queue(queueTask, Math.random() * 2000, "C")
meet.queue(queueTask, Math.random() * 2000, "D")

// Note that the entire series of sequential tasks operates like a single concurrent
// task relative to the other concurrent tasks.

function finished(msg) {
	console.log(msg)
}

setTimeout(function() {
	console.log('seems like a nice time to set the completion call-back');
	meet.allDone(finished, "Everyone is done!")
}, 4000);
