什么nodejs库最像jQuery的延迟?

I've become a skilled user of jQuery's new and amazing Deferred module, and as I'm easing into using more of Node.js, I find myself wanting something exactly like it in much of my Node.js programming: callbacks that block until a collection of promises devolves to resolved, with the freedom to add to the array on-the-fly as the task grows in complexity-- such as when one processes a tree of data, the size of which is not known at the start of the task.

我已经熟练地使用了jQuery新的、令人惊叹的延迟模块，并逐渐开始使用更多的Node。js，我发现自己在我的大部分节点中都想要一个和它完全一样的东西。js编程:回调块，直到有一组承诺得到解决，随着任务在复杂度上的增长，可以*地添加到数组中，比如当一个进程处理一棵数据树时，在任务开始时不知道它的大小。

But node-fibers requires a whole new executable, Q()'s interface is just damned confusing, and node-step only seems to handle single-task synchronizations.

但是node-纤程需要一个全新的可执行文件，Q()的接口非常混乱，而且node-step似乎只处理单任务同步。

Has someone just ported jQuery's Deferreds to a node-ready form? It doesn't seem that unlikely, nor does it seem that Deferreds is dependent upon DOM-available features, but I haven't found a server-side equivalent.

是否有人刚刚将jQuery的延迟移植到节点就绪表单中?这似乎不太可能，延迟似乎也不依赖于dom可用的特性，但我还没有找到与之对应的服务器端特性。

If you want the same API, there's nothing stopping you from using jQuery itself under Node. Just npm install jquery, then:

如果您希望使用相同的API，那么在Node下使用jQuery本身是没有任何障碍的。只需安装jquery npm，然后:

var $ = require('jquery');
var deferred = $.Deferred();

I don't think you can get any closer than jQuery deferred lib for nodeJS.

我认为对于nodeJS来说，jQuery延迟库是最接近的。

This wasn't around when the question was asked, but according to the readme it uses (and passes) the jquery tests. It appears to be exactly identical minus the (jQuery||$). prefix.

当被问到这个问题时，这并没有发生，但是根据readme，它使用(并通过)jquery测试。它看起来完全相同(jQuery||$)。前缀。

Though not exactly what you are looking for, is moderately close. I find that the callback chaining is fairly natural, though deeply nested chains can be a bit difficult to keep up with.

虽然不完全是你想要的，但还是比较接近。我发现回调链接是相当自然的，尽管深度嵌套的链可能有点难以跟上。

Both of which are probably much closer to what you are looking for. :)

这两个可能都更接近于你所寻找的。:)
