问题描述

TLDR :如何通过全局作用域(或引用另一个类中的导入类)来创建一个模块(通过ES6语法导入)?

TLDR: How can I make a module (imported via ES6 syntax) globally scoped (or reference an imported class inside another class)?

我正在从一个未正确实施的包中导入一个模块(不出口等),但遇到一些问题。

I'm importing a module from a package which wasn't implemented properly (no export etc) but am running into some issues.

我正在使用 var 将模块设置为全局(不太好),例如

What I am doing is using var to set the module to global (not great) e.g.

var Example = require('./node_modules/example/long_path_to_file.js');

因为我需要像我的类一样使用它(该模块控制这个和类实例在全局范围内是不可用的,所以我不能象我通常会使用我的类):

As I need to use it like so in my class (the module takes control of this and class instances aren't available in the global scope so I can't use my class as I normally would):

new window.Example(...)

这不是很好,因为我使用webpack并且更喜欢使用正确的es6语法

This works but it isn't great as I'm using webpack and would prefer to use the proper es6 syntax

import Example from './example';

然后在 example.js

export default Example = require('./node_modules/example/long_path_to_file.js');

但是这意味着它不再是全局范围的,我无法找到修复。

However this means it is no longer global scoped, and I'm unable to find a fix.

我尝试过像 window.Example = Example 但不起作用。

I've tried things like window.Example = Example but it doesn't work.

推荐答案

如果您使用 webpack ,可以轻松设置。所以这里是一个简单的例子,如何实现它。

If you are using webpack it's easy to setup it. So here is a simple example how to implement it.

webpack.config.js

webpack.config.js

module.exports = {
  entry: 'test.js',
  output: {
    filename: 'bundle.js',
    path: 'home',
    library: 'home' // it assigns this module to the global (window) object
  }
  ...
}

some.html

some.html

<script>console.log(home)</script>

另外如果你打开你的 bundle.js 文件你会看到webpack是如何为你做的。

Also if you open your bundle.js file you will see how webpack did it for you.

var home =  // main point
/*****/ (function(modules) blablabla)
...

webpack库 配置。

我希望它会帮助你。

谢谢
