Best practice rules for Storybook

Installation

You'll first need to install ESLint:

npm install eslint --save-dev
# or
yarn add eslint --dev

Next, install eslint-plugin-storybook:

npm install eslint-plugin-storybook --save-dev
# or
yarn add eslint-plugin-storybook --dev

And finally, add this to your .eslintignore file:

// Inside your .eslintignore file
!.storybook

This allows for this plugin to also lint your configuration files inside the .storybook folder, so that you always have a correct configuration and don't face any issues regarding mistyped addon names, for instance.

For more info on why this line is required in the .eslintignore file, check this ESLint documentation.

If you are using flat config style, add this to your configuration file:

export default [
  // ...
  {
    // Inside your .eslintignore file
    ignores: ['!.storybook'],
  },
];

ESLint compatibility

Use the following table to use the correct version of this package, based on the version of ESLint you're using:

ESLint version	Storybook plugin version
^9.0.0	^0.10.0
^8.57.0	^0.10.0
^7.0.0	~0.9.0

Usage

Configuration (.eslintrc)

Use .eslintrc.* file to configure rules in ESLint < v9. See also: https://eslint.org/docs/latest/use/configure/.

Add plugin:storybook/recommended to the extends section of your .eslintrc configuration file. Note that we can omit the eslint-plugin- prefix:

{
  // extend plugin:storybook/<configuration>, such as:
  "extends": ["plugin:storybook/recommended"]
}

This plugin will only be applied to files following the *.stories.* (we recommend this) or *.story.* pattern. This is an automatic configuration, so you don't have to do anything.

Overriding/disabling rules

Optionally, you can override, add or disable rules settings. You likely don't want these settings to be applied in every file, so make sure that you add a overrides section in your .eslintrc.* file that applies the overrides only to your stories files.

{
  "overrides": [
    {
      // or whatever matches stories specified in .storybook/main.js
      "files": ['**/*.stories.@(ts|tsx|js|jsx|mjs|cjs)'],
      "rules": {
        // example of overriding a rule
        'storybook/hierarchy-separator': 'error',
        // example of disabling a rule
        'storybook/default-exports': 'off',
      }
    }
  ]
}

Configuration (eslint.config.[c|m]?js)

Use eslint.config.[c|m]?js file to configure rules using the flat config style. This is the default in ESLint v9, but can be used starting from ESLint v8.57.0. See also: https://eslint.org/docs/latest/use/configure/configuration-files-new.

import storybook from 'eslint-plugin-storybook';

export default [
  // add more generic rulesets here, such as:
  // js.configs.recommended,
  ...storybook.configs['flat/recommended'],

  // something ...
];

In case you are using utility functions from tools like tseslint, you might need to set the plugin a little differently:

import storybook from 'eslint-plugin-storybook';
import somePlugin from 'some-plugin';
import tseslint from 'typescript-eslint';

export default tseslint.config(
  somePlugin,
  storybook.configs['flat/recommended'] // notice that it is not destructured
);

Overriding/disabling rules

Optionally, you can override, add or disable rules settings. You likely don't want these settings to be applied in every file, so make sure that you add a flat config section in your eslint.config.[m|c]?js file that applies the overrides only to your stories files.

import storybook from 'eslint-plugin-storybook';

export default [
  // ...

  ...storybook.configs['flat/recommended'],
  {
    files: ['**/*.stories.@(ts|tsx|js|jsx|mjs|cjs)'],
    rules: {
      // example of overriding a rule
      'storybook/hierarchy-separator': 'error',
      // example of disabling a rule
      'storybook/default-exports': 'off',
    },
  },

  // something ...
];
