如何将单个 Node.js 文件拆分为单独的模块 [英] How to split a single Node.js file into separate modules

问题描述

我想将代码拆分成不同的文件.我目前在同一个文件中编写了所有 get 和 post 方法，但我想要更高的可读性和可管理性.

I want to split the code into different files. I currently write all get and post methods in the same file, but I want greater readability and manageability.

我尝试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 get 和 post 方法无法叫.我包括这个:

I've tried to put the code in different files, but while running the main app, the rest of get and post methods in other files are not able to called. I include this:

var Db = require('/filename.js');//...但我不能调用这些方法.

var Db = require('/filename.js'); // ...but I can't call those methods.

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?

I want to split my single file code for readability. How do I achieve this?

推荐答案

只需查看模块文档:

以/开头寻找绝对路径，例如:

Starting with / looks for absolute paths, eg:

require('/home/user/module.js');

./以调用文件所在的路径开头.

./ starts with the path where the calling file is located.

require('./lib/module.js');

__dirname 与 ./具有相同的效果:

__dirname has the same effect than ./:

require( __dirname + '/module.js');
