@dendavidov/eslint-config

Opinionated ESLint flat config for TypeScript-based Node.js projects.

• ESLint 9+ flat config
• Node.js 24.x required (engines.node); this repo pins an exact patch in .nvmrc / Dockerfile for CI
• TypeScript, Prettier, Jest, and Security rules out of the box
• Jest globals automatically available in test files
• eslint-plugin-import with eslint-import-resolver-typescript (and node) so import/no-unresolved respects tsconfig.json / path aliases where configured

Installation

Add a single dev dependency — ESLint is bundled as a normal dependency of @dendavidov/eslint-config, so you do not install eslint, plugins, or parsers yourself; they come in transitively.

pnpm add -D @dendavidov/eslint-config
# or: npm i -D @dendavidov/eslint-config

Run the CLI with npx eslint or pnpm exec eslint (or a lint script that calls eslint), which resolves the binary from your install tree. Your project pins one package version; ESLint’s semver is chosen by this config’s dependencies.

Usage

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

CommonJS:

const config = require('@dendavidov/eslint-config');
module.exports = config;

ESM:

import config from '@dendavidov/eslint-config';
export default config;

Or extend with your own rules:

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

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.
