SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Guides developers to design, build, and optimize modern React 18+ applications, promoting scalable architecture, strong typing, and robust testing practices.

Core Features & Use Cases

  • Component architecture and composition: Encourage composition over inheritance, use of custom hooks for logic reuse, and clean file organization.
  • State management and data handling: Guide selection of Zustand or Jotai for client-side global state and React Query for server state, plus performance patterns.
  • Testing and quality: Recommend Vitest and React Testing Library for user-centric tests and maintainable code.

Quick Start

Ask the AI to scaffold a complete modern React component using TypeScript, hooks, and best practices.

FAQPage Schema
How do I structure React components using composition over inheritance?

Structure React components by favoring composition over inheritance and extracting reusable logic into custom hooks. This approach ensures clean file organization and scalable component architecture for modern React 18+ applications.

What's the best way to manage server state in React with React Query?

Use React Query to manage server state while relying on Zustand or Jotai for client-side global state. This separation of concerns optimizes data fetching and application performance in modern React projects.

How do I write user-centric tests for React components with Vitest?

Write user-centric tests for React components using Vitest combined with React Testing Library. This testing strategy focuses on user interactions rather than implementation details to ensure maintainable code.

Can I use Zustand and Jotai for global state management in React 18?

Yes, you can use Zustand or Jotai for global state management in React 18. They are recommended for handling client-side state, complementing React Query which manages server state for robust performance patterns.

How do I scaffold a modern React component with strict TypeScript typings?

Scaffold a modern React component by applying strict TypeScript typings alongside custom hooks and composition patterns. This ensures type safety and clean project structure for scalable architecture.
