What problem does it solve?

Developing large-scale JavaScript applications without type safety leads to runtime errors and maintenance headaches. This Skill provides expert guidance for TypeScript 5.7+, integrating Vitest 2.1 for testing, Biome 1.9 for code quality, and strict typing to ensure your applications are reliable, scalable, and easy to maintain.

Core Features & Use Cases

• TypeScript 5.7+ Best Practices: Guides on leveraging new language features, advanced type inference, and strict mode configurations.
• Modern Testing: Implement test-driven development using Vitest 2.1 for fast unit and integration tests.
• Unified Code Quality: Enforce Biome 1.9 for linting, formatting, and import organization, replacing multiple tools.
• Efficient Package Management: Best practices for npm, pnpm, or Bun for faster dependency installation and project setup.
• Use Case: When starting a new Next.js project, this Skill can help you configure tsconfig.json for strict typing, set up Vitest for testing, and integrate Biome for consistent code quality, accelerating your development.

Quick Start

Initialize a new TypeScript project

npm init -y npm install -D typescript @types/node npx tsc --init

Install Vitest and Biome
