@onlycat/eslint

Shared ESLint, Prettier and TypeScript configuration for OnlyCat projects.

This package provides a modern baseline for TypeScript projects, with a focus on:

• ESLint flat config
• TypeScript-aware linting
• Prettier formatting
• 4-space indentation
• 120-character print width
• Vite React TypeScript support
• Separate Node and web TypeScript presets

Installation

Install the shared config package and its peer dependencies:

npm install --save-dev @onlycat/eslint eslint prettier typescript typescript-eslint @eslint/js

TypeScript configs

Use the base config for shared strictness, then extend the runtime-specific preset that matches the project.
