@couds/eslint-config

Shared ESLint 10 flat config for React and Node.js projects with Prettier integration. These are the rules I use across my personal projects.

Requirements

• ESLint 10+ (flat config format)
• ESM project — your eslint.config.js must use import/export

Installation

npm install --save-dev @couds/eslint-config eslint @eslint/js

eslint and @eslint/js are peer dependencies that your project must provide. typescript is bundled automatically (required internally by @eslint-react).

Usage

React

// eslint.config.js
import reactConfig from '@couds/eslint-config/react';

export default [
  ...reactConfig,
  // project-specific overrides
];

Node.js

// eslint.config.js
import nodeConfig from '@couds/eslint-config/node';

export default [
  ...nodeConfig,
  // project-specific overrides
];

The default export (@couds/eslint-config) is an alias for the React config.

What's included

Both configs

• @eslint/js recommended — ESLint core rules baseline
• eslint-plugin-import-x recommended — import/export correctness (ESLint 10-native fork of eslint-plugin-import)
• eslint-plugin-prettier — runs Prettier as an ESLint rule (prettier/prettier: error)
• eslint-config-prettier — disables ESLint rules that conflict with Prettier formatting

React only

• @eslint-react/eslint-plugin recommended — React and hooks correctness rules built for ESLint 10
• eslint-plugin-jsx-a11y recommended — accessibility rules for JSX
• Browser + Node globals, JSX parsing enabled

Node only

• Node globals only, no JSX

Notable rule overrides shared by both: arrow-body-style is enforced (always); no-console, max-len, no-underscore-dangle, class-methods-use-this, and several import-x style rules are disabled.

Notes

• Flat config only — .eslintrc.* files are not supported
• The Airbnb config base and react/function-component-definition style rule were removed during the ESLint 10 migration
