webpack browserify --ignore 等效吗？

Question

我有一些代码在浏览器中不起作用，除非我“忽略”两个包，我可以用 browserify: 做到这一点browserify files.js -i fs-extra -i request --standalone files > files.browserify.js，结果代码可以正常工作，但是如果我尝试用 webpack 来做，代码会抱怨模块被丢失的。

...
  plugins: [
      new webpack.IgnorePlugin(/fs-extra$/),
      new webpack.IgnorePlugin(/request$/),
      new webpack.IgnorePlugin(/fs$/)
  ],
...

test.webpack.js:7655 Uncaught Error: Cannot find module "request"
    at webpackMissingModule (test.webpack.js:7655)
    at Object.exports.byteLength (test.webpack.js:7655)
    at __webpack_require__ (test.webpack.js:20)
    at Object.<anonymous> (test.webpack.js:17012)
    at __webpack_require__ (test.webpack.js:20)

我怀疑可能的WebPack不会创建一个“空存根”像browserify作用：--ignore, -i Replace a file with an empty stub. Files can be globs.。

我能做些什么来解决这个问题？

你要找的是null-loader它返回一个空模块：

module: {
    loaders: [
        {
            test: /^(fs-extra|fs|request)$/,
            loader: "null"
        },
        ...
]

安装：

$ npm i -D null-loader
