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.
