@dendavidov/eslint-config-react

Opinionated eslint-config for React.js SPA with ESLint 9+ (flat config). Includes security best-practice rules via eslint-plugin-security.

• ESLint 9+ flat config (bundled eslint + @eslint/js; plugin ecosystem is not fully on ESLint 10 yet, so this package currently resolves ESLint 9.x)
• Node.js 24.x required (engines.node); this repo pins an exact patch in .nvmrc / Dockerfile for CI
• ESLint is bundled as a normal dependency — you do not add eslint as its own devDependency; resolve the CLI with npx eslint, pnpm exec eslint, or a lint script

Installation

Install this package and its peer dependencies (ESLint plugins and parsers this config expects):

pnpm add -D @dendavidov/eslint-config-react @typescript-eslint/eslint-plugin @typescript-eslint/parser eslint-config-prettier eslint-import-resolver-typescript eslint-plugin-import eslint-plugin-jest eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-security eslint-plugin-testing-library

(or the equivalent npm i -D … with the same package list.)

eslint itself is installed transitively with @dendavidov/eslint-config-react; use npx eslint or pnpm exec eslint so the binary comes from your install tree.

Usage

Create eslint.config.js in the root of your project:

import config from '@dendavidov/eslint-config-react';

export default config;

Or extend with your own rules:

import config from '@dendavidov/eslint-config-react';

export default [
  ...config,
  {
    rules: {
      // Your custom rules
    },
  },
];

Add script to package.json:

{
  "scripts": {
    "lint": "eslint './src/**/*.{ts,tsx,js,jsx}'"
  }
}

Node.js version

This config requires Node.js 24.x (see engines.node on npm). Development of this package uses a pinned patch in .nvmrc (and Dockerfile) so CI and Dependabot stay aligned.
