@stylistic/eslint-plugin-js

JavaScript stylistic rules for ESLint, migrated from eslint core.

Credits to all contributors who have committed to the original rules.

TIP

We recommend using @stylistic/eslint-plugin as it includes the rules for both JavaScript and TypeScript

Install

npm i -D @stylistic/eslint-plugin-js

Add @stylistic/js to your plugins list, and prefix stylistic rules with @stylistic/js:

Flat Config

// eslint.config.js
import stylisticJs from '@stylistic/eslint-plugin-js'

export default [
  {
    plugins: {
      '@stylistic/js': stylisticJs
    },
    rules: {
      'indent': ['error', 2],
      '@stylistic/js/indent': ['error', 2],
      // ...
    }
  }
]

Legacy Config

// .eslintrc.js
module.exports = {
  plugins: [
    '@stylistic/js'
  ],
  rules: {
    'indent': ['error', 2],
    '@stylistic/js/indent': ['error', 2],
    // ...
  }
}
