How to split a single Node.js file into separate modules
提问by Raj
I want to split the code into different files. I currently write all getand postmethods in the same file, but I want greater readability and manageability.
我想将代码拆分为不同的文件。我目前在同一个文件中编写所有get和post方法，但我想要更高的可读性和可管理性。
I've tried to put the code in different files, but while running the main app, the rest of getand postmethods in other files are not able to called.
I include this:
我试图将代码放在不同的文件中，但是在运行主应用程序时，其他文件中的其余部分get和post方法无法调用。我包括这个：
var Db = require('/filename.js'); // ...but I can't call those methods.
var Db = require('/filename.js'); // ...但我不能调用这些方法。
I want to split my single file code for readability. How do I achieve this?
我想拆分我的单个文件代码以提高可读性。我如何实现这一目标？

Just have a look at the module documentation:
看看模块文档：
Starting with / looks for absolute paths, eg:
以 / 开头查找绝对路径，例如：
require('/home/user/module.js');
./ starts with the path where the calling file is located.
./ 以调用文件所在的路径开头。
require('./lib/module.js');
__dirname has the same effect than ./:
__dirname 与 ./ 具有相同的效果：
require( __dirname + '/module.js');
