cluster&forever

cluster & forever

虽然 nodejs 原生已经提供了 cluster 模块，大部分情况下可以满足我们的基本需求，但这两个模块 cluster 和 forever 都提供了更强大的功能。

cluster 及 forever 都能让你的 nodejs 应用的管理更加方便，比如启动、重启、停止你的应用。

他们也都可以保证应用的稳定性，如果你的 nodejs 程序存在错误而使进程关闭了，cluster 或 forever 都能自动重启他们，以保证 nodejs 应用零宕机。

node-dev

node-dev 模块是一个开发工具，当你的 js 文件修改保存后，他会自动重启服务进程，嫌 CTRL + C / up / down 费劲的同学可以尝试用它减轻开发调试的烦恼。

另外它还支持桌面提醒

使用方法

<span class="pln" style="color: rgb(0, 0, 0);">node</span><span class="pun" style="color: rgb(102, 102, 0);">-</span><span class="pln" style="color: rgb(0, 0, 0);">dev </span><span class="pun" style="color: rgb(102, 102, 0);">--</span><span class="pln" style="color: rgb(0, 0, 0);">debug app</span><span class="pun" style="color: rgb(102, 102, 0);">.</span><span class="pln" style="color: rgb(0, 0, 0);">js</span>

html2jade

html2jade 模块可以方便的转换现有的 HTML 到 Jade 格式。

目前仅支持 OS X 和 Linux 平台。

使用方法

抓取 URL 并转换源码

<span class="pln" style="color: rgb(0, 0, 0);">html2jade http</span><span class="pun" style="color: rgb(102, 102, 0);">:</span><span class="com" style="color: rgb(136, 0, 0);">//twitter.com // 会输出到终端控制台</span><span class="pln" style="color: rgb(0, 0, 0);">
html2jade http</span><span class="pun" style="color: rgb(102, 102, 0);">:</span><span class="com" style="color: rgb(136, 0, 0);">//twitter.com > twitter.jade // 输出到 twitter.jade 文件</span>

转换现有 HTML 文件

<span class="pln" style="color: rgb(0, 0, 0);">html2jade mywebpage</span><span class="pun" style="color: rgb(102, 102, 0);">.</span><span class="pln" style="color: rgb(0, 0, 0);">html </span><span class="com" style="color: rgb(136, 0, 0);"># 输出到 mywebpage.jade</span><span class="pln" style="color: rgb(0, 0, 0);">
html2jade </span><span class="kwd" style="color: rgb(0, 0, 136);">public</span><span class="com" style="color: rgb(136, 0, 0);">/*.html  # 转换所有 .html 文件到 .jade</span>
