下面是項目中用到的一段代碼

// webpack version 2.2.1

entry: [
      // must be first entry to properly set public path
      './src/webpack-public-path',
      'webpack-hot-middleware/client?reload=true',
      path.resolve(__dirname, 'src/index.js') // Defining path seems necessary for this to work consistently on Windows machines.
   ],
output: {
      path: path.resolve(__dirname, 'dist'), // Note: Physical files are only output by the production build task `npm run build`.
      publicPath: '/',
      filename: 'bundle.js'
   },

請問webpack-public-path代表的是什么意思？

我的理解是在entry中設(shè)置output的publicpath，如果這樣的話webpack-public-path在項目中又代表什么呢？
