SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes examples (resource) and references (resource) components.

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

npm install -D vitest biome

Run tests

npx vitest

Lint and format

npx biome check . --apply

Claude can then assist with type definitions and component design.

Frequently Asked Questions about moai-lang-typescript

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up TypeScript 5.7+ with strict type safety for a Next.js project?

TypeScript 5.7+ enables strict type safety through enhanced tsconfig.json configuration, the satisfies operator for precise type constraints, and server/client boundary enforcement in Next.js App Router. Configure strict mode, install @types/node, and use advanced type patterns to catch errors at compile time rather than runtime.

Can I use Vitest 2.1 for testing React and Next.js applications?

Vitest 2.1 provides fast unit and integration testing for React 19 and Next.js 16 App Router projects. It integrates seamlessly with TypeScript strict mode and supports server component and server action testing, enabling test-driven development without leaving your type-safe workflow.

What's the best way to enforce code quality across a TypeScript project?

Biome 1.9 unifies linting, formatting, and import organization in a single tool, replacing multiple separate tools. It enforces consistent code quality aligned with your tsconfig.json strict settings, reducing configuration overhead and ensuring scalable, maintainable codebases.

How do I implement end-to-end type safety between React components and APIs?

End-to-end type safety combines strict TypeScript typing, tRPC for type-safe API contracts, and Zod validation for runtime schema enforcement. This ensures React 19 components, server actions, and API handlers all operate with shared type definitions across UI and backend layers.

Does TypeScript 5.7+ support decorators and advanced type patterns for large-scale projects?

TypeScript 5.7+ supports decorators and advanced type patterns like deferred module evaluation and the satisfies operator, enabling scalable architecture for large React and Next.js applications. These features enhance maintainability and reduce boilerplate in complex type hierarchies.

What package manager should I use with Vitest and Biome in a TypeScript project?

npm, pnpm, and Bun all work with TypeScript 5.7+, Vitest 2.1, and Biome 1.9. Use pnpm or Bun for faster dependency installation and improved disk efficiency in modern Next.js and React projects.
