Node
应用还有一个很吸引人的好处：
Node
是平台独立的。它不是第一项或唯一一项平台
独立的服务器技术，然而，平台独立远不只是二进制包的问题。例如，因为有了
Mono
，
你可以在
Linux
服务器上运行
.NET
应用
，但是由于文档的缺失和系统不兼容，这会是一
项痛苦的工作。同样，你可以在
W
indows
服务器上运行
PHP
应用，但是通常来说搭建它
没有在
Linux
服务器上那么容易
。而在各大主流操作系统（
Windows
、
macOS
和
Linux
）
上搭建
Node
都轻而易举
，不同操作系统协作起来也很容易。在各个网站设计小组中，混
合使用
PC
和
Mac
是寻常事
。某些开发平台，如
.NET
，就给前端开发和设计人员带来了
不少的挑战（因为他们常常使用
Mac
）
，严重影响了他们的协作和工作效率。只要几分钟
（甚至几秒钟）就可以在任何操作系统上运行起来一个能正常工作的服务器，这个美梦已
经成真了。
1.6
Node
生态系统
自然，
Node
位于这个技术栈的核心位置。正是
Node
，使得
JavaScript
可以运行于服务器
之上，脱离浏览器而存在，从而允许使用用
JavaScript
编
写的框架（如
Express
）。另一个
重要的组件就是数据库，这将在第
13
章深入讨论
。除非是最简单的
Web
应用，否则都需
要一个数据库。有几种数据库在
Node
中比在其他语言中还要好用。
所有主要的关系型数据库（
MySQL
、
MariaDB
、
PostgreSQL
、
Oracle
、
SQL
Server
）都有
Node
的接口
，这不奇怪。这些数据库经过多年发展已经非常强大 ...
