webpackJsonp is not defined - quasar 0.14.7

  • I have a large, finished project that uses the 0.14.7 version of the quasar framework, which is returning this error when I try to run the generated file in /dist/js/app.js, because of time issues I can not carry this to version 0.15.

    From what I have read about the problem the CommonsChunkPlugin plugin has updated and some settings related to minChunks, the problem is that I do not know anything about webpack configurations, and so I read it is a very big ecosystem, so the time item prevents me from deciphering it now.

    If anyone can help me fix this problem I appreciate it.

    Solution in webpack github:

    my webpack.prod.conf file:

      path = require('path'),
      config = require('../config'),
      cssUtils = require('./css-utils'),
      webpack = require('webpack'),
      merge = require('webpack-merge'),
      baseWebpackConfig = require('./webpack.base.conf'),
      ExtractTextPlugin = require('extract-text-webpack-plugin'),
      HtmlWebpackPlugin = require('html-webpack-plugin'),
      OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin'),
      CopyWebpackPlugin = require('copy-webpack-plugin'),
      SWPrecacheWebpackPlugin = require('sw-precache-webpack-plugin'),
      fsUtils = require('./fs-utils')
    module.exports = merge(baseWebpackConfig, {
      module: {
        rules: cssUtils.styleRules({
          sourceMap: config.build.productionSourceMap,
          extract: true,
          postcss: true
      devtool: config.build.productionSourceMap ? '#source-map' : false,
      plugins: [
        new webpack.optimize.UglifyJsPlugin({
          sourceMap: config.build.productionSourceMap,
          minimize: true,
          compress: {
            warnings: false
        // Compress extracted CSS. We are using this plugin so that possible
        // duplicated CSS from different components can be deduped.
        new OptimizeCSSPlugin({
          cssProcessorOptions: {
            safe: true
        // extract css into its own file
        new ExtractTextPlugin({
          filename: '[name].[contenthash].css'
        new HtmlWebpackPlugin({
          filename: path.resolve(__dirname, '../dist/index.html'),
          template: 'src/index.html',
          inject: true,
          minify: {
            removeComments: true,
            collapseWhitespace: true,
            removeAttributeQuotes: true
            // more options:
            // https://github.com/kangax/html-minifier#options-quick-reference
          // necessary to consistently work with multiple chunks via CommonsChunkPlugin
          chunksSortMode: 'dependency',
          serviceWorkerLoader: `<script>${fsUtils.loadMinified(path.join(__dirname,
        // split vendor js into its own file
        new webpack.optimize.CommonsChunkPlugin({
          name: 'vendor',
          minChunks: function (module, count) {
            // any required modules inside node_modules are extracted to vendor
            return (
              module.resource &&
              /\.js$/.test(module.resource) &&
                module.resource.indexOf('quasar') > -1 ||
                  path.join(__dirname, '../node_modules')
                ) === 0
        // extract webpack runtime and module manifest to its own file in order to
        // prevent vendor hash from being updated whenever app bundle is updated
        new webpack.optimize.CommonsChunkPlugin({
          name: 'manifest',
          chunks: ['vendor']
        // copy custom static assets
        new CopyWebpackPlugin([
            from: path.resolve(__dirname, '../src/statics'),
            to: 'statics',
            ignore: ['.*']
        // service worker caching
        new SWPrecacheWebpackPlugin({
          cacheId: 'website-irradiar',
          filename: 'service-worker.js',
          staticFileGlobs: ['dist/**/*.{js,html,css,woff,svg}'],
          minify: true,
          stripPrefix: 'dist/'

  • It was no big deal, nor was there a bug, just needed to use lite-server to test the build file.

  • How to fix it??

  • If I understand @anonimo correctly the issue was that he was not using a webserver for serving the build files.
    Build files only work when served via a proper webserver and not when you open the index file in a browser.
