Webpack-如何将非模块脚本加载到全局范围窗户 [英] Webpack - How to load non module scripts into global scope | window

问题描述

因此，我需要从窗口范围(这是一系列窗口范围的函数)运行一些供应商文件，此外，我还希望将一些polyfill捆绑到供应商捆绑包中.

so i have a few vendor files that i need to run from window scoped (it's a bunch of window scoped functions) plus i have some polyfills that i would like to bundle into the vendor bundle as well.

所以我尝试了这样的事情:

So i tried something like this:

new webpack.optimize.CommonsChunkPlugin({
    name: 'vendor',
    filename: 'js/vendor.min.js',
    minChunks: Infinity,
})

entry: {
    'vendor' : ['./vendor.js', './vendor2.js', './polyfills.js']
}

现在，当我运行Webpack构建时，它会生成我的供应商捆绑包，但它们都包装在webpackJsonP包装器中，因此在窗口范围内无法访问这些功能.

Now when i run my webpack build it does generate my vendor bundle but it's all wrapped in a webpackJsonP wrapper so the functions are not accessible on the window scope.

我还考虑过使用诸如ProvidePlugin之类的方法，但是由于我没有像jQuery这样定义的名称(在该名称下所有内容都被映射)，所以我根本无法使用它.

I've also looked at using something like the ProvidePlugin but i couldn't make that work at all since i don't have a defined name like jQuery where everything is mapped under.

在webpack中甚至有可能吗?

Is this even possible in webpack?

推荐答案

使用脚本加载器插件:

如果您希望整个脚本在全局名称空间中注册，则必须使用 script-loader .不建议这样做，因为它会破坏模块的含义；-) 但是，如果没有其他方法:

If you want the whole script to register in the global namespace you have to use script-loader. This is not recommend, as it breaks the sense of modules ;-) But if there is no other way:

npm install --save-dev script-loader

Webpack文档

此加载器在全局上下文中评估代码，就像您将要评估的那样 将代码添加到脚本标签中.在这种模式下，每个普通库 应该管用.需求，模块等未定义.

This loader evaluates code in the global context, just like you would add the code into a script tag. In this mode every normal library should work. require, module, etc. are undefined.

注意:该文件将作为字符串添加到捆绑软件中.没有最小化 通过webpack，因此请使用最小化版本.也没有开发工具 支持此加载程序添加的库.

Note: The file is added as string to the bundle. It is not minimized by webpack, so use a minimized version. There is also no dev tool support for libraries added by this loader.

然后可以在entry.js文件中导入内联:

Then in your entry.js file you could import it inline:

import  "script-loader!./eluminate.js"

或通过配置:

module.exports = {
  module: {
    rules: [
      {
        test: /eluminate\.js$/,
        use: [ 'script-loader' ]
      }
    ]
  }
}

以及您的entry.js

import './eluminate.js';

正如我所说，它污染了全局名称空间:

As I said, it pollutes the global namespace:
