Node.js是一套用来编写高性能网络服务器的Javascr ipt工具包，一系列的变化由此开始。比较独特的是，Node.js会假设你是在POSIX环境下运行它Linux 或 Mac OS X。如果你是在Windows下，那就需要安装MinGW以获得一个仿POSIX的环境。在Node中，Http是首要的。Node为创建http服务器作了优化，所以你在网上看到的大部分示例和库都是集中在web上(http框架、模板库等）。 -Node.js is a Javascr ipt toolkit for the preparation of high-performance network server, which began the series of changes. Unique, Node.js will assume that you run it on Linux or Mac OS X is POSIX environment. If you are under Windows, it would need to install MinGW to get an imitation POSIX environment. In the Node, Http primary. Node to create a http server optimized, so most of the examples and libraries that you see online are focused on the web (http fr a mework, template libraries, etc.).
