npm i --save-dev @runespoorstack/eslint-config @rushstack/eslint-config@latest eslint@latest prettier@latest typescript@latest 

♾️ Usage

Create .eslintrc.cjs in the root of the project.

Choose the core config

Use a native JavaScript base config:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  "extends": ["@runespoorstack/eslint-config/core/base-js"]
}

Use a TypeScript base config:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  "extends": ["@runespoorstack/eslint-config/core/base-ts"]
}

Use a native React base config:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  ignorePatterns: ['!.storybook'],
  "extends": ["@runespoorstack/eslint-config/core/react-js"]
}

Use a TypesScript React base config:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  ignorePatterns: ['!.storybook'],
  "extends": ["@runespoorstack/eslint-config/core/react-ts"]
}

Choose a mixins

Use a Prettier mixin:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  ignorePatterns: ['!.storybook'],
  "extends": [
    "@runespoorstack/eslint-config/core/react-js", 
    "@runespoorstack/eslint-config/mixins/prettier"
  ]
}

Use a Tailwind mixin:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  ignorePatterns: ['!.storybook'],
  "extends": [
    "@runespoorstack/eslint-config/core/react-ts", 
    "@runespoorstack/eslint-config/mixins/prettier", 
    "@runespoorstack/eslint-config/mixins/tailwind"
  ]
}

Use a Jest mixin:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  ignorePatterns: ['!.storybook'],
  "extends": [
    "@runespoorstack/eslint-config/core/react-js", 
    "@runespoorstack/eslint-config/mixins/prettier", 
    "@runespoorstack/eslint-config/mixins/tailwind", 
  ],
   overrides: [
    {
       files: ['**/*.@(spec|test).[tj]s?(x)'], // or any other pattern
      extends: [
        '@runespoorstack/eslint-config/mixins/jest'
      ]
    }
  ]
}

Use a Vitest mixin:

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  ignorePatterns: ['!.storybook'],
  "extends": [
    "@runespoorstack/eslint-config/core/react-js", 
    "@runespoorstack/eslint-config/mixins/prettier", 
    "@runespoorstack/eslint-config/mixins/tailwind", 
  ],
   overrides: [
    {
      files: ['**/*.@(spec|test).[tj]s?(x)'], // or any other pattern
      extends: [
        '@runespoorstack/eslint-config/mixins/vitest'
      ]
    }
  ]
}

Add your own rules

// This is a workaround for https://github.com/eslint/eslint/issues/3458
require('@rushstack/eslint-config/patch/modern-module-resolution');
module.exports = {
  ignorePatterns: ['!.storybook'],
  "extends": [
    "@runespoorstack/eslint-config/core/react-js", 
    "plugin:@tanstack/eslint-plugin-query/recommended"
  ]
}

⚠️ no-restricted-imports overrides

Be careful with adding your own no-restricted-imports rules! We use a set of predefined restriction rules to protect you from serious mistakes out of the box:

• Use default imports from lodash/*. - to save your bundle size.
• Use custom 'render', 'renderHook' methods. - to cover the 80% usage of these methods (you commonly use only the custom once).
• Please use default @mui/icons-material/* import instead. - to save your bundle size.
• Use default imports from @mui/material/<Component> - to save your bundle size. = MUI: Do not use the third level imports - to save your bundle size.

If you define your own no-restricted-imports, all the predefined once would be cleared. So in case of adding new rules or overriding only the separate rule, you should copy and paste the full no-restricted-imports rule definition from our source code.

⚠️ Linting .storybook folder

Make sure you have remove .storybook from ignore patterns to be able to lint this folder. By default eslint ignore all the .* files.

Use ignorePatterns: ['!.storybook'],

Run eslint

Run eslint check:

eslint . --ext .ts,.tsx,.js,.jsx,.cjs,.mjs --quiet

Run eslint autofix:

eslint . --ext .ts,.tsx,.js,.jsx,.cjs,.mjs --fix
