@bratislava/eslint-config

Base ESLint configuration for Bratislava projects. Built for ESLint v9 flat config format.

Part of a monorepo of shareable ESLint configurations — see the full repo for NestJS, Next.js, and React variants.

Installation

npm install --save-dev @bratislava/eslint-config eslint typescript

Usage

Create eslint.config.mjs in your project root:

import baseConfig from "@bratislava/eslint-config";

export default baseConfig;

Or use individual exports to compose your own config:

import {
  baseConfig,
  typescriptRules,
  eslintRules,
  sonarjsRules,
  simpleImportSortConfig,
} from "@bratislava/eslint-config";

Prettier

prettierBase is a shared Prettier config object. Spread it in your prettier.config.mjs and add project-specific options:

// prettier.config.mjs
import { prettierBase } from '@bratislava/eslint-config'

export default {
  ...prettierBase,
  // project-specific overrides, e.g.:
  // plugins: ['prettier-plugin-tailwindcss'],
  // tailwindStylesheet: './src/pages/globals.css',
}
