在node.js中创建链式方法？ [英] Create chained methods in node.js?

问题描述

是否可以在node.js中创建这样异步的链式方法

Is it possible to create chained methods that are asynchronous like this in node.js

File.create('file.jpg').rename('renamed.jpg').append('Hello World')

那个就是说非阻塞。

推荐答案

你基本上想要抽象文件的异步性质处理您的API的操作。

You basically want to abstract the asynchronous nature of the file-handling operations on your API.

可以这样做，我建议您查看以下文章：

It can be done, I would recommend you to give a look to the following article:

• JavaScript中的异步方法队列链接

• Asynchronous method queue chaining in JavaScript

这篇文章是由Dustin Diaz撰写的，他现在正在 @ anywhere JavaScript API ，他完全按照您的意愿行事，使用简单的Queue实现，可以创建流畅的界面，独立于任何回调。

The article was written by Dustin Diaz, who currently works on the @anywhere JavaScript API, and he does exactly what you want, using a using a simple Queue implementation, a fluent interface can be created, being independent of any callback.

asynchronicity 是隐藏的，它由你的API内部处理，这是一个很好的简单技术。

The asynchronicity is hidden and it is handled internally by your API, it's a nice and simple technique.
