问题描述
在Node.js中，我们谈论事件循环很多，所以我想知道我们正在谈论哪个事件循环，Javascript事件循环还是libuv事件循环?我猜想libuv事件循环可以为复用I/O的多个操作系统提供抽象吗?我对吗?如果不是这样，请解释一下这些东西是如何工作的?我需要一些内部知识，我知道什么是事件循环，我只想知道它是如何连接的?
In Node.js we a lot talk about the event loop, so I want to know which event loop we are talking about, the Javascript event loop or the libuv event loop ?I guess libuv event loop that provides abstraction for multiple operating system of multiplexing i/o ? Am I right? If not so please explain how this stuff works? I need some internal knowledge, I know what an event loop is, I just want to know how it is connected?
推荐答案
当前，节点使用libuv提供的事件循环-即其默认事件循环:uv_default_loop().请参阅:Nikhil Marathe libuv简介:
Currently Node uses the the event loop provided by libuv - namely its default event loop: uv_default_loop(). See: An Introduction to libuv by Nikhil Marathe:
注意:node.js使用默认循环作为其主循环.如果你是 编写绑定时，您应该意识到这一点.
Note: node.js uses the default loop as its main loop. If you are writing bindings you should be aware of this.
设计概述页面上有一个linuv体系结构图.在libuv API文档中:
There is a linuv architecture diagram on the Design overview page in the libuv API documentation:
过去，libev的事件循环是在Node中使用的.请参见了解node.js事件循环高田美纪(Mikito Takada):
In the past, libev's event loop was used in Node. See Understanding the node.js event loop by Mikito Takada:
