@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:

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

Check out the migration guide for more details.
