@ktam/lint-node

This package provides a reusable set of ESLint and Prettier configurations for ESM Node.js projects.

• Prettier configuration with enforced code style rules.
• Compatibility with Vitest for testing and Unicorn for improving code quality.
• Prettier Plugin for formatting and automatically sorting package.json properties.

Installation

To install this package, you'll need pnpm (version 9 or higher) and Node.js (version 20 or higher):

pnpm add -D @ktam/lint-node

Ensure your project is using TypeScript and ESLint compatible versions:

pnpm add -D typescript eslint

Usage

ESLint Configuration

To use the ESLint configuration, create an eslint.config.js in the root of your project and import the configuration:

export { default } from '@ktam/lint-node/eslint';

You can adjust or extend the configuration if needed by modifying the imported rules.

Prettier Configuration

To apply the Prettier configuration, create a prettier.config.js file in the root of your project and import the configuration:

export { default } from '@ktam/lint-node/prettier';

File Structure

• eslint.config.base.js: Base ESLint configuration, including rules for JavaScript, TypeScript, and Node.js projects.
• prettier.config.base.js: Base Prettier configuration enforcing code styles such as 2-space tabs, single quotes, and trailing commas.

Configuration Highlights

• ESLint:

  • Enforces best practices for JavaScript and TypeScript.
  • Integrates TypeScript linting via @typescript-eslint for stricter type checks.
  • Includes Unicorn and Perfectionist plugins for improved code quality and import/export ordering.
  • Custom rules to ensure concise, maintainable code (e.g., disallowing console.log, enforcing template literals).
  • Special configurations for Vitest testing files.

• Prettier:

  • Ensures consistent formatting across JavaScript, TypeScript, and package.json files.
  • Uses prettier-plugin-packagejson to format package.json.
