草地鹨旅游网站
贯穿本书，我们将使用一个持续更新的示例网站：为草地鹨旅游公司（
Meadowlark Travel
）
而做的一个假想的网站，这个公司是为到俄勒冈州旅行的人提供服务的。如果你对创建
API
更感兴趣，不用担心：这个网站除了提供功能正常的网页之外，还会暴露一套
API
。

初始工作
先创建一个新目录，这将是你的项目的根目录。在本书中，每当说项目目录、应用目录或
应用根目录，都是指这个目录。
你可能想让
Web
应用的文件跟通常属于项目的其他文件（例如会议笔记、文
档等）分离。为此，推荐你把应用目录作为项目目录的子目录。例如，对
于草地鹨旅游网站，我会把项目放在
~/projects/meadowlark
中
，把应用放在
~/projects/meadowlark/site
中。
npm
在一个名为
package.json
的文件里管理项目的依赖关系以及项目的元数据。创建这个

npm init
：它会问你一系列问题，然后生成
package.json
文件以
开始项目（对于“

”这个提问，按照项目名，使用
meadowlark.js
）。

npm
，你可能都会收到一条警告信息，提示缺少项目描述或版本
库字段。忽略这些警告是没问题的，不过如果你想消除它们，则需要编辑
package.json
文件
，填上
