@vbetsch/config-eslint

A modular and extensible ESLint configuration collection for TypeScript projects, designed to enforce high code quality standards while remaining flexible.

🧩 Modules

This package provides several configuration modules that can be composed to fit your project's needs:

| Module | Description | |--------------------------------------------------------------------------------------------------------------------|------------------------------------------------------| | base | Core TypeScript rules and best practices. | | jsx | Specialized rules for React and JSX accessibility. | | naming | Enforces strict and consistent naming conventions. | | prettier | Disables conflicting rules and integrates Prettier. | | spellcheck | Checks for common typos in identifiers and comments. | | strict | Opinionated rules for maximum type safety and rigor. |

🏗️ Installation

We recommend using Node version lts/krypton -> v24.14.1.

Install the NPM package in your project:

npm install -D @vbetsch/config-eslint

Note: Depending on the modules you use (e.g., jsx or prettier), you must also install the corresponding peer dependencies like eslint-plugin-react or prettier.

• base:
  • No more dependencies needed
• jsx:
  • tsconfig module jsx
  • react
  • eslint-plugin-react
  • eslint-plugin-jsx-a11y
• naming:
  • No more dependencies needed
• prettier:
  • eslint-config-prettier
  • eslint-plugin-prettier
• spellcheck:
  • eslint-plugin-spellcheck
• strict:
  • eslint-plugin-import

🚀 Getting started

To use these configurations, import them into your flat eslint.config.mjs file:

// NOTE: You can name imports like you want
import baseVbetsch from '@vbetsch/config-eslint/base';
import prettierVbetsch from '@vbetsch/config-eslint/prettier';
import strictVbetsch from '@vbetsch/config-eslint/strict';

export default [
  ...baseVbetsch,
  ...strictVbetsch,
  ...prettierVbetsch,

  // IMPORTANT: You have to add these lines only for the strict module !
  {
    languageOptions: {
      parserOptions: {
        project: './tsconfig.json',
        tsconfigRootDir: import.meta.dirname,
      },
    },
  },
];
