jshint在webpack.config文件中怎么配置(webpack2.X)?

Question

以前用webpack1.X时候webpack.config文件中是这样写的

npm install jshint-loader --save-dev

var path = require('path');
var APP_PATH = path.resolve(ROOT_PATH, 'app');
module: {
    preLoaders: [
      {
        test: /.jsx?$/,
        include: APP_PATH,
        loader: "jshint-loader"
      }
    ],
    jshint: {
    "esnext": true
  }
}

现在webpack2.X preLoaders跟jshint的写法都变了,我应该怎么修改下config代码??
