npm install --save-dev eslint eslint-plugin-github

Add github to your list of plugins in your ESLint config.

JSON ESLint config example:

{
  "plugins": ["github"]
}

Extend the configs you wish to use.

JSON ESLint config example:

{
  "extends": ["plugin:github/recommended"]
}

Import the eslint-plugin-github, and extend any of the configurations using getFlatConfigs() as needed like so:

import github from 'eslint-plugin-github'

export default [
  github.getFlatConfigs().browser,
  github.getFlatConfigs().recommended,
  github.getFlatConfigs().react,
  ...github.getFlatConfigs().typescript,
  {
    files: ['**/*.{js,mjs,cjs,jsx,mjsx,ts,tsx,mtsx}'],
    ignores: ['eslint.config.mjs'],
    rules: {
      'github/array-foreach': 'error',
      'github/async-preventdefault': 'warn',
      'github/no-then': 'error',
      'github/no-blur': 'error',
    },
  },
]

The available configs are:

• internal
  • Rules useful for github applications.
• browser
  • Useful rules when shipping your app to the browser.
• react
  • Recommended rules for React applications.
• recommended
  • Recommended rules for every application.
• typescript
  • Useful rules when writing TypeScript.

Note: This is experimental and subject to change.

The react config includes rules which target specific HTML elements. You may provide a mapping of custom components to an HTML element in your eslintrc configuration to increase linter coverage.

By default, these eslint rules will check the "as" prop for underlying element changes. If your repo uses a different prop name for polymorphic components provide the prop name in your eslintrc configuration under polymorphicPropName.

{
  "settings": {
    "github": {
      "polymorphicPropName": "asChild",
      "components": {
        "Box": "p",
        "Link": "a"
      }
    }
  }
}

This config will be interpreted in the following way:

• All <Box> elements will be treated as a p element type.
• <Link> without a defined as prop will be treated as a a.
• <Link as='button'> will be treated as a button element type.
