@carlos3g/eslint-config

Composable ESLint flat-config presets for TypeScript, NestJS, React and Expo — the linting half of carlos3g's code style.

Install once, pick the preset that matches the stack.

yarn add -D @carlos3g/eslint-config eslint typescript

// eslint.config.mjs — NestJS API
import nest from '@carlos3g/eslint-config/nest';
export default nest;

// eslint.config.mjs — Expo / React Native
import expo from '@carlos3g/eslint-config/expo';
export default expo;

Presets

Each preset is a flat-config array.

| Subpath | Use for | | ---------------------------------- | ---------------------------------------------------------- | | @carlos3g/eslint-config/base | Any TypeScript project — TS rules + sensible defaults | | @carlos3g/eslint-config/nest | NestJS APIs — base + jest layer + Prettier | | @carlos3g/eslint-config/expo | Expo / React Native — base + react + tanstack-query + RTL | | @carlos3g/eslint-config/react | React (web) — base + react + react-hooks + Prettier | | @carlos3g/eslint-config/jest | Jest add-on for spec/e2e files | | @carlos3g/eslint-config/prettier | Prettier integration (always last when composing manually) |

base is the foundation: eslint:recommended + typescript-eslint strictTypeChecked. The nest, react and expo presets already include base and Prettier — pick exactly one, never compose base + a stack preset manually. jest and prettier are composable add-ons; prettier must always come last so it can disable conflicting stylistic rules.

Composing manually

import { base, jest, prettier } from '@carlos3g/eslint-config';
import tseslint from 'typescript-eslint';

export default tseslint.config(
  ...base,
  ...jest,
  {
    rules: {
      /* project overrides */
    },
  },
  ...prettier
);
