Storybook Webpack 5

⚠️ Warning: this document is out of date.

For the most recent webpack5 instructions see MIGRATION.md.

Storybook experimental Webpack 5 support

Storybook 6.2 includes experimental Webpack 5 support. Webpack 5 brings a variety of performance improvements, as well as exciting new features like module federation. Here's a quick guide to get you going.

Intro

Storybook uses webpack to bundle its UI ("manager") and also user code in an iframe ("preview"). In Storybook 6.2, the manager is bundled in Webpack 4, and the preview can either be bundled in Webpack 4 (default) or Webpack 5 (opt-in). In Storybook 6.3, the manager is also bundled in Webpack 5 when the preview is bundled with Webpack 5.

Installation

NOTE: Before you try out Storybook's webpack5 support, make sure your project works with Webpack 5. For example, create-react-app v4 (CRA v4) is not webpack5-compatible, so if you have a CRA project, you'll need to upgrade to CRA v5 which uses webpack5. Once you've verified webpack5 in your project, you can either do a clean install or an upgrade.

Upgrading from Webpack 4

If you're upgrading an existing Storybook installation:

npx sb@next upgrade --prerelease

Then add dependencies:

npm i -D @storybook/builder-webpack5@next @storybook/manager-webpack5@next webpack@5

Note that the webpack@5 dev dependency forces webpack5 to be hoisted, since SB also contains a webpack4 dependency

Then update your .storybook/main.js:

module.exports = {
  core: {
    builder: "webpack5",
  },
};

Upgrading from 6.2 Webpack 5

If you were using Webpack 5 in 6.2, and have upgraded to 6.3, you probably need to add @storybook/manager-webpack5 as a dependency:

npm i -D @storybook/manager-webpack5@next

Clean install

If your project doesn't have Storybook installed:

npx sb@next init --builder webpack5

This adds storybook and automatically performs the extra steps descripted in the "Upgrade from Webpack 4" section.

Troubleshooting

Currently all storybook addons assume webpack 4. If you run into issues, try disabling addons and see if that fixes it. If you find an addon that needs to be upgraded to support Webpack 5, please file an issue and let us know!

Webpack 5 support is still experimental. If you run into problems, please check to see if somebody's already filed an issue Storybook repo and upvote it if there's an existing issue. If there's no existing issue, please file one and title it Webpack5: (problem summary).

Yarn resolutions

Some webpack5 projects are using Yarn resolutions to force a specific version of webpack across the entire project. We don't recommend this because it causes problems for Storybook which still uses webpack4 to build its "manager" UI (not user code). However, if you must use resolutions including all of the following packages is a workaround seems to patch over the issue:

{
  "resolutions": {
    "webpack": "^5.0.0",
    "css-loader": "^5.0.0",
    "dotenv-webpack": "^6.0.0",
    "html-webpack-plugin": "^5.0.0",
    "style-loader": "^2.0.0",
    "terser-webpack-plugin": "^5.0.0",
    "webpack-dev-middleware": "^4.1.0",
    "webpack-virtual-modules": "^0.4.2"
  }
}

We're considering a proper solution in #14044.

FWIW, I was also getting the TypeError: Cannot read property 'get' of undefined with a clean install storybook. Interestingly enough, switching from npm to yarn help.

Great, thank you! I'm now onto this error :( Granted this is when trying to run a dev server, not through storybook but figured I'd ask as others have had similar errors in this thread webpack-dev-middleware: options has an unknown property 'logLevel':

This may be precisely the problem 😄

Do you have a .env file in your project? If so, storybook may be attempting to read it and may be using an old version of dotenv-webpack which isn't compatible with webpack 5. If this is the case, you need to install your own version of dotenv-webpack to prevent storybook from installing its own outdated dependency.

At least this used to be the case several months ago; perhaps by now it's something completely different.

I'm still facing with a strange issue: Although the terminal is reporting all is fine, when I enter into Storybook URL, it looks empty:

I am using Angular 12 and storybook 6.3.0.
Following the instructions, I can get everything working locally but when I try to build-storybook, it hangs at

Anyone else saw this before and is there a workaround?

I finally got this to work.

Key takeaways:

 "devDependencies": {
    "@babel/core": "7.15.0",
    "@babel/preset-env": "7.15.0",
    "@storybook/addon-actions": "6.4.0-alpha.30",
    "@storybook/addon-controls": "6.4.0-alpha.30",
    "@storybook/addon-docs": "6.4.0-alpha.30",
    "@storybook/addon-postcss": "2.0.0",
    "@storybook/addon-viewport": "6.4.0-alpha.30",
    "@storybook/addons": "6.4.0-alpha.30",
    "@storybook/builder-webpack5": "6.4.0-alpha.30",
    "@storybook/manager-webpack5": "6.4.0-alpha.30",
    "@storybook/preset-scss": "1.0.3",
    "@storybook/react": "6.4.0-alpha.30",
    "@svgr/webpack": "5.5.0",
    ...
    "@types/webpack": "5.28.0",
    "@types/dotenv-webpack": "7.0.3",
    ...
    "dotenv-webpack": "7.0.3",
    ...
    "webpack": "5.51.1",

The above dependencies got me past the 99% blocker. Afterwards, any story that contained an imported svg failed to load .. because storybook was trying to load svg using file loader, with the base loader that it has for assets.

To get past that blocker and to have stories that contained icons working too, I had to make the base file loader on the storybook webpack config ignore svgs, and I provided loader rules for svgs instead.

Inside webpackFinal under main.js:

const fileLoaderRule = rules.find(rule => rule.test && rule.test.test('.svg'));

fileLoaderRule.exclude = /\.svg$/;

rules.push({
  test: /\.svg$/,
  issuer: /\.(js|ts)x?$/,
  use: ['@svgr/webpack', 'url-loader'],
});
    

Just push the rule - no loader order problem if svgs don't go through file loader at all. Load them as urls to resolve imports and then load them using svgr.

Et voila, storybook with webpack 5 FINALLY working.

Hi,

it's been several days since i stuck with the issue,

i tried all the solution but no luck.

will be please help me out.

issue is :

start-storybook works but build-storybook fails

start-storybook works smooth with add-ons as well.

but build-storybook fails, if i add any of the addons in .storybook.main.ts

and add

module.exports = {

I am also getting this error with Storybook 7 migration from v6. Any solution for this issue?

Will a .babelrc in the .storybook folder with the following content help?

{
  "presets": [
    "@babel/react",
    "@babel/typescript"
  ]
}

(also, what's in your main.js inside .storybook)?
