mid.js v0.0.5

mid.js

A lightweight flow control for Node and Browsers. Similar to async.js but more than enjoyable API :).

Installation

npm install mid.js --save

Examples

Didn't use any flow control:

setTimeout(function(){
	var a = doSomething()
	setTimeout(function(){
		doSomething2(a)
		setTimeout(function(){
			console.log('done')
		}, 1000)
	}, 1000)
}, 1000)

use mid.js

var mid = require('mid.js')

mid('sync')
	.use(function(next){
		setTimeout(function(){
			var a = doSomething()
			next(a)
		}, 1000)
	})
	.use(function(a, done){
		setTimeout(function(){
			doSomething(a)
			done()
		}, 1000)
	})
	.done(function(){
		setTimeout(function(){
			console.log('done')
		}, 1000)
	})

async

var mid = require('mid.js')

mid('async')
	.use(function(){
		$.ajax({})
	})
	.use(function(){
		$.ajax({})
	})
	.once(function(){
		// here will trigger when all async process done
	})

in loop:

var mid = require('../mid')
var masync = mid('async')

for(var i = 0; i < 2; i++){
    masync.use(function(done){
        setTimeout(function (){
            done()
        }, 1000)
    })
}

masync.once(function (){
    console.log('done')
})
