Core configuration package containing:

• Biome configurations: For JavaScript/TypeScript formatting and linting
• TypeScript configurations: Base tsconfig.json files for different project types
• CLI tool: Interactive setup and configuration management

@mh4gf/eslint-config

ESLint configuration package with:

• Base configuration: JavaScript best practices and code quality rules
• TypeScript support: Type-aware linting rules and import management
• Vitest integration: Testing-specific rules and globals

Installation

# Install individual packages
npm install --save-dev @mh4gf/configs
npm install --save-dev @mh4gf/eslint-config

# Or with pnpm
pnpm add -D @mh4gf/configs @mh4gf/eslint-config
