@lcooper/eslint-config-react

An ESlint shareable flat config for React projects. Extends @lcooper/eslint-config.

Installation

The peer dependency eslint must be installed alongside this package.

install with npm:

npm install -D eslint @lcooper/eslint-config-react

install with yarn:

yarn add -D eslint @lcooper/eslint-config-react

This config is meant to be used in addition to the base @lcooper/eslint-config config, so that should be installed as well.

Note: This project requires Eslint version >=8.56, and NodeJS version ^18.18.0 || >=20.0.0.

Usage

Add an eslint.config.js config file to your project's root directory.

Note: this package exports a single flat config object, so no need for the ... spread syntax when using it.

import baseConfig from '@lcooper/eslint-config';
import reactConfig from '@lcooper/eslint-config-react';

export default [
    ...baseConfig,
    reactConfig,
];

If your project does not specify "type": "module" in its package.json file, then eslint.config.js must be in CommonJS format:

const baseConfig = require('@lcooper/eslint-config'),
    reactConfig = require('@lcooper/eslint-config-react');

module.exports = [
    ...baseConfig,
    reactConfig,
];

This project is no longer compatable with the legacy eslintrc format, and requires you use the flat config format. Check out this page for more details about migrating from the eslintrc format to the flat config format.

File Matching

By default, this config matches .js, .mjs, and .jsx files using the glob **/*.{js,mjs,jsx}. More specificity can be achieved by overwriting the files option with your own globs, like in this example:

import baseConfig from '@lcooper/eslint-config';
import reactConfig from '@lcooper/eslint-config-react';

export default [
    ...baseConfig,
    {
        ...reactConfig,
        files: ['src/**/*.{js,mjs,jsx}'],
    },
];
