关于webpack 生成文件目录的问题？

webpack配置:

output: {
    path: './dist/components',
    publicPath: 'http://***.***.cn/mx/components/',
    //filename: '[name].[chunkhash:8].js',
    filename: '[name].js'
},

生成的文件如：

问题是：我想把生成的图片放到images文件中，生成的js按业务模块分类放到不同的文件夹中.

如何配置？ 谢谢!

我自己工程的打包代码，请自行参考。

var path = require('path')
var config = require('../config')
var precss = require('precss')
var autoprefixer = require('autoprefixer')
var projectRoot = path.resolve(__dirname, '../')
var ExtractTextPlugin = require('extract-text-webpack-plugin')

module.exports = {
  entry: {
    index: ['./src/scripts/vitarem.js', './src/scripts/index.js'],
    index2: ['./src/scripts/vitarem.js', './src/scripts/index2.js'],
  },

    path: config.build.assetsRoot,
    publicPath: config.build.assetsPublicPath,
    filename: '[name].js'

    }
  },
  resolveLoader: {

  eslint: {

  postcss: function() {
    return [autoprefixer, precss]
  }
}
