I was finally able to get 5.1.11 to build, using the following webpack.config.js:

const and = require('crocks/logic/and');
const isString = require('crocks/predicates/isString');
const compose = require('crocks/helpers/compose');
const propOr = require('crocks/helpers/propOr');

const includes = x => xs => xs.includes(x);
const some = p => xs => xs.some(p);

const getUse = propOr(null, 'use');

const isStyleLoader = and(isString, includes('style-loader'));

const usesStyleLoader = compose(some(isStyleLoader), getUse);

const LIT_CSS_REGEXP = /src\/(.*)\.css$/

const options = require('../.babelrc');

const LIT_CSS_RULE = {
  test: LIT_CSS_REGEXP,
  loader: 'lit-css-loader',
}

const transpilePackages = [
  'lit-html',
  'lit-element',
  '@open-wc',
  'crocks'
]

// this is a separate config for only those packages
// the main storybook will use the .babelrc which is needed so storybook itself works in IE
const TRANSPILE_PACKAGES_RULE = {
  test: /\.js$/,
  include: transpilePackages.map(package => new RegExp(`node_modules(\\/|\\\\)(${package})(.*)\\.js$`)) ,
  exclude: [/@babel\/runtime/, /core-js/, /axe-core/, /@storybook/],
  loader: 'babel-loader',
  options: {
    plugins: [
      '@babel/plugin-syntax-dynamic-import',
      '@babel/plugin-proposal-object-rest-spread',
    ],
    presets: [
      [
        '@babel/preset-env',
        {
          useBuiltIns: 'entry',
          corejs: '3',
        },
      ],
    ],
    babelrc: false,
  }
}

const BABEL_LOADER_RULE = {
  test: /\.js$/,
  loader: 'babel-loader',
  exclude: [/@babel\/runtime/, /core-js/, /axe-core/],
  options
}

module.exports = ({ config }) => {
  config.module.rules = [
    ...config.module.rules,
    BABEL_LOADER_RULE,
    LIT_CSS_RULE,
    TRANSPILE_PACKAGES_RULE,
  ];

  config.module.rules
    .find(usesStyleLoader)
    .exclude = LIT_CSS_REGEXP;

  return config;
};

I'd have to look at a full reproduction of the issue, but this may be related to @open-wc/demoing-storybook having /@storybook/addon-storysource as a runtime dependency instead of a peerDependency. There may be a version mismatch between the version that you upgraded to and the one they're managing as a dep.

Can you try upgrading to 5.1.7? We've done a bunch of core-js related fixes in the past few releases and it's possible that this is already fixed.

I'm getting these with 5.1.8 and with 5.2.0-alpha.26

Could be related.

This is after patching @open-wc/demoing-storybook's webpack config to set corejs.version to 3 with this patch file

I have the sense this is not open-wc related. I removed my dependencies on open-wc packages with some deft copypasting, and got the same errors.

@bennypowers do you have a repo somewhere to take a look?

Just to clarify, when you say you removed the dependencies on open-wc packages, do you mean you essentially replicated the entire @open-wc/demoing-storybook setup with a clean storybook install?

Unfortunately nothing I can share at the moment.

... essentially replicated the entire @open-wc/demoing-storybook setup with a clean storybook install?

Yes, specifically, reimplemented defaultConfig inside my local storybook webpack config

Same error after upgrading to 5.1.8 using React. I do not believe it's Polymer specific based on that (just wanted to clarify).

Module not found: Error: Cannot find module '[PROJECT_PATH]/node_modules/@storybook/addon-storysource/loader.js![PROJECT_PATH]/node_modules/core-js/modules/es.symbol.js'

This suddenly began to work after I updated my .storybook/webpack.config.js from 

config.module.rules.push({
  test: /\.(js|jsx)$/,
  loaders: [require.resolve('@storybook/addon-storysource/loader')],
  enforce: 'pre',
})

to be more specific to where my stories live

config.module.rules.push({
  test: /story.(js|jsx|ts|tsx)$|stories\/*.(js|jsx|ts|tsx)/,
  loaders: [require.resolve('@storybook/addon-storysource/loader')],
  enforce: 'pre',
})

Hi! Sorry if this is "too many cooks", but I am also having this issue with 5.1.8 and React. I get a ton of these errors while building webpack:

If I downgrade to 5.1.3, things continue to work again. Happy to share more about my repo if asked!

Dear Stale,

Your enthusiasm, though appreciated in its own right, is in this instance misplaced. We sincerely wish you the best going forward, but please give our issue a chance.

Yours,

-- some devs

With that out of the way, I'm here to confirm that this issue is still relevant to 5.2.0-beta.7

bennypowers picture bennypowers on 24 Jul 2019

@pksunkara we might need to give the lazy-universal-dotenv an upgrade to core-js v3?

ndelangen picture ndelangen on 24 Jul 2019

Yeah, looks like it

pksunkara picture pksunkara on 24 Jul 2019

lazy-universal-dotenv already depends on core-js 3?

    "core-js": "^3.0.4",

I was able to build storybook successfully with 5.2.0-beta.18 and this command start-storybook -p 9001 -s storybook-static

However, once the page loaded, I got these console errors:

TypeError: "_ref4.edition is undefined"

I get this in FF only, but in chromium (edgium) it works. I will file a separate issue.

I was finally able to get 5.1.11 to build, using the following webpack.config.js:

const and = require('crocks/logic/and');
const isString = require('crocks/predicates/isString');
const compose = require('crocks/helpers/compose');
const propOr = require('crocks/helpers/propOr');

const includes = x => xs => xs.includes(x);
const some = p => xs => xs.some(p);

const getUse = propOr(null, 'use');

const isStyleLoader = and(isString, includes('style-loader'));

const usesStyleLoader = compose(some(isStyleLoader), getUse);

const LIT_CSS_REGEXP = /src\/(.*)\.css$/

const options = require('../.babelrc');

const LIT_CSS_RULE = {
  test: LIT_CSS_REGEXP,
  loader: 'lit-css-loader',
}

const transpilePackages = [
  'lit-html',
  'lit-element',
  '@open-wc',
  'crocks'
]

// this is a separate config for only those packages
// the main storybook will use the .babelrc which is needed so storybook itself works in IE
const TRANSPILE_PACKAGES_RULE = {
  test: /\.js$/,
  include: transpilePackages.map(package => new RegExp(`node_modules(\\/|\\\\)(${package})(.*)\\.js$`)) ,
  exclude: [/@babel\/runtime/, /core-js/, /axe-core/, /@storybook/],
  loader: 'babel-loader',
  options: {
    plugins: [
      '@babel/plugin-syntax-dynamic-import',
      '@babel/plugin-proposal-object-rest-spread',
    ],
    presets: [
      [
        '@babel/preset-env',
        {
          useBuiltIns: 'entry',
          corejs: '3',
        },
      ],
    ],
    babelrc: false,
  }
}

const BABEL_LOADER_RULE = {
  test: /\.js$/,
  loader: 'babel-loader',
  exclude: [/@babel\/runtime/, /core-js/, /axe-core/],
  options
}

module.exports = ({ config }) => {
  config.module.rules = [
    ...config.module.rules,
    BABEL_LOADER_RULE,
    LIT_CSS_RULE,
    TRANSPILE_PACKAGES_RULE,
  ];

  config.module.rules
    .find(usesStyleLoader)
    .exclude = LIT_CSS_REGEXP;

  return config;
};

This is likely fixed by https://github.com/storybookjs/storybook/commit/4c35a213b73c649add0a6b9733e806e877d6b0de (#10679)

BridgeAR picture BridgeAR on 8 May 2020

If someone wants that commit be make it into @storybook/polymer, they'd have to open a PR here https://github.com/storybookjs/storybook/tree/master/app/polymer

FYI we're dropping support for storybook for polymer and focussing on supporting plain web-components instead.
