webpack打包单页面如何引用的js

var webpack = require('webpack');
var fs = require('fs');
var path = require('path');
var fse = require('fs-extra');

const debug = process.env.NODE_ENV !== 'production';

function entries(jsPath) {
  var dirnames = fs.readdirSync(jsPath);

  var entries = {}, entry;

  for (var i = 0; i < dirnames.length; i++) {
    var dirname, basename;
    var jsList = [];
    dirname = dirnames[i];
    var files = fs.readdirSync(jsPath + '/' + dirname);
    for (var j = 0; j < files.length; j++) {
      entry = files[j];

      basename = path.basename(entry, '.js');
      jsList.push(path.join(jsPath, dirname, entry));
    }
    entries[path.join(dirname, 'app')] = jsList;
  }


  return entries;
}

var option = {
  entry: entries(__dirname + '/js/src'),
  output: {
    path: __dirname + '/dist/',
    filename: '[name].js'
  },
  plugins: [
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      }
    })
  ]
}
var compiler = webpack(option);
compiler.run(function() {
  fse.copy( __dirname + '/page/', __dirname + '/dist/');
  console.log('success');
});
