在node.js中加载并执行外部js文件，可以访问局部变量吗？ [英] Load and execute external js file in node.js with access to local variables?

问题描述

在node.js中执行简单的 include（'./ path / to / file'）命令类型是否容易/可行？

Is it easy/possible to do a simple include('./path/to/file') type of command in node.js?

我想要做的就是访问本地变量并运行脚本。人们通常如何组织比简单的hello世界更大的node.js项目？ （功能齐全的动态网站）

All I want to do is have access to local variables and run a script. How do people typically organize node.js projects that are bigger than a simple hello world? (A fully functional dynamic website)

例如，我希望有以下目录：

For example I'd like to have directories like:

/ models

/ views

...等

推荐答案

只需做一个 require（'。 /yourfile.js'）;

将您想要外部访问的所有变量声明为全局变量。
所以而不是

Declare all the variables that you want outside access as global variables. So instead of

var a =hello它将是

GLOBAL.a =hello或只是

a =你好

这显然很糟糕。您不希望污染全球范围。
相反，建议方法是 export 你的函数/变量。

This is obviously bad. You don't want to be polluting the global scope. Instead the suggest method is to export your functions/variables.

如果你想要MVC模式看看Geddy。

If you want the MVC pattern take a look at Geddy.
