Example of mixing query params between multiple loaders (which wasn't possible at one time) with webpack 2.

webpack2-loaders.js

module.exports = config; 

const config = {
  module: {
    rules: [ //<=== 'loaders' works as a fallback but for .23+ best to start using "rules" instead.
      {
        test: /\.less/, 
        loaders: [
          "style-loader",
          {loader: "css-loader", query: {}},
          {loader: "less-loader", query: {}}
        ]
      }
    ],
  }
};
