# mid.js
A lightweight flow control for Node and Browsers. Similar to [async.js](https://github.com/caolan/async) but more than enjoyable API :).
## Installation
npm install mid.js --save
## Examples
Didn't use any flow control:
```js
setTimeout(function(){
var a = doSomething()
setTimeout(function(){
doSomething2(a)
setTimeout(function(){
console.log('done')
}, 1000)
}, 1000)
}, 1000)
```
use mid.js
```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
```js
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:
```js
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')
})
```
## API
### mid(['async'|'sync'])
set run `use` functions as `async` or `sync`
### use([function(...args, next)])
process functions for `async` or `sync`.
The behavior like [Express.js](http://expressjs.com/guide/using-middleware.html) middleware.
### done([function])
invoking when ecah processes done.
### once([function])
invoking once when all async process done.
