   <a href="http://www.open-open.com/lib/view/open1338390222073.html" target="_blank">Node.js</a>是一套用来编写高性能网络服务器的JavaScript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)。   <br />    <br />    <p><strong>Node.js v0.8</strong> 版本指日可待了,0.7 版本再经过1个或者2个版本发布就转为稳定版了。</p>    <p><strong>NodeJS v0.6</strong> 和 <strong>Node.js v0.8</strong> 在 API 上有一些小变化。</p>    <h2 id="deprecated">废弃:</h2>    <ul>     <li><code>http.Client()</code></li>     <li><code>path.{exists,existsSync}</code> was moved to <code>fs.{exists,existsSync}</code></li>     <li><code>tty.setRawMode(mode)</code> was moved to <code>tty.ReadStream#setRawMode()</code> (i.e. <code>process.stdin.setRawMode()</code>)</li>    </ul>    <h2 id="removed">删除:</h2>    <ul>     <li><code>waf</code> build system - <code>node.js</code> will be using <code>gyp</code> now * If you are a native module author, migrate to <a href="/misc/goto?guid=4958343045341119651"><code>node-gyp</code></a> ASAP!</li>     <li><code>sys</code> throws</li>    </ul>    <h2 id="changed">改动:</h2>    <ul>     <li> <p><code>process</code> * <code>process.stdin.on('keypress')</code> will not be emitted by default, as it’s an internal API.</p> </li>     <li> <p><code>cluster</code></p>      <ul>       <li><code>cluster.fork()</code> no longer return a <code>child_process.fork()</code> object use <code>cluster.fork().process</code> to get the object.</li>       <li>the <code>'death'</code> event on the <code>cluster</code> object is renamed to <code>'exit'</code>.</li>       <li>the <code>kill()</code> method is renamed to <code>destroy()</code>.</li>       <li>the <code>CLUSTER_WORKER_ID</code> env is now called <code>CLUSTER_UNIQUE_ID</code>, but you should not have used that anyway.</li>       <li>workers do now kill them self when they accidentally losses there connection with the master.</li>      </ul> </li>     <li> <p><code>http</code></p>      <ul>       <li><code>http.Server</code> emits <code>'connect'</code> event instead of <code>'upgrade'</code> when the CONNECT method is requested.</li>       <li><code>http.ServerResponse</code> sends <code>Date:</code> header by default.
