nd-queue
简单的队列执行控制。
安装
$ npm install nd-queue --save使用
特殊用法，混入到类中
// mixin to classes
var Queue = require('nd-queue');
var WidgetHasQueue = Widget.extend({
// 使用 handlebars
Implements: [Queue]
...
});run
synchronous. run queue member step by step (one invokes by previous one with done).
var queue = new Queue()
// use function
queue.use(function([arg1, arg2, ...], done, fail){
// do some (a)sync job, then
done()
})
// use functions
queue.use([function([arg1, arg2, ...], done, fail){
// do some (a)sync job, then
done()
}, ...])
// use function with context key (defaults: 'ctx')
queue.use(function([arg1, arg2, ...], done, fail){
// do some (a)sync job, then
done()
}, 'upload')
// dynamically pass arguments to queue members
queue.run([arg1, arg2, ... ], [function callback([arg1, arg2, ... ]) {
// do some jobs for done
}], [function callback([arg1, arg2, ... ]) {
// do some jobs for fail
}])any
asynchronous. if any member of the queue is finished, call the callback for done, otherwise call the callback for fail.
all
asynchronous. if all members of the queue is finished, call the callback for done, otherwise call the callback for fail.
