Webpack 使用附加加载程序的简易网页包

我有一个简单的网页包配置（Aurelia的默认配置）

我们使用了一个库（autobahn），它试图加载package.json。 当这种情况发生时，它就会出错

./~/autobahn/package.json
Module parse failed: /media/aurelia_app/node_modules/    autobahn/package.json Unexpected token (2:9)
You may need an appropriate loader to handle this file type.
| {
|   "_args": [
|     [
|       {
 @ ./~/autobahn/lib/autobahn.js 17:12-38
 @ ./~/autobahn/index.js
 @ ./src ^\.\/.*$
 @ ./~/aurelia-loader-webpack/dist/commonjs/aurelia-loader-webpack.js
 @ multi aurelia

为了让它工作，我们必须为json添加一个额外的加载器

这是我们的配置文件

"use strict";

解决方案是在基本配置中为加载程序添加模块

const baseConfig = {
  entry: {
    'app': [/* this is filled by the aurelia-webpack-plugin */],
    'aurelia-bootstrap': coreBundles.bootstrap,
    'aurelia': coreBundles.aurelia.filter(pkg =>     coreBundles.bootstrap.indexOf(pkg) === -1)
  },
  module: {
    loaders: [
        { test: /\.json$/, loader: 'json-loader' }
    ]
   },

  output: {
    path: outDir,
  }
}
