ESLint Base Configuration

Shareable base ESLint flat config for modern JavaScript projects.

Requirements

• ESLint ^10.0.0
• Node ^20.19.0 || ^22.13.0 || >=24.0.0

Installation

npm install --save-dev eslint @patricktabar/eslint-config-base

Usage

Use the package from an eslint.config.js file:

import configBase from '@patricktabar/eslint-config-base';

export default [...configBase];

What it includes

• modern language options for ECMAScript modules
• @stylistic/eslint-plugin recommended rules
• base JavaScript rule sets from this package's rules/ modules

Customizing rules

Add your own config entries after the shared config so your overrides win:

import configBase from '@patricktabar/eslint-config-base';

export default [
  ...configBase,
  {
    rules: {
      semi: ['error', 'always'],
    },
  },
];

Migrating from 1.x

Version 2.x is a breaking release.

• it targets ESLint 10
• it exports flat config arrays instead of legacy .eslintrc config
• it requires a root eslint.config.js file
