React Principles
The Living Cookbook for Modern React
A high-end developer reference implementation for scalable React architectures. Isolated patterns, real-world examples, and production-ready code.

Beyond simple code snippets.
Most pattern libraries stop at a Gist. We provide the full context.
React Principles is a collection of isolated patterns combined with real-world implementations. We show you how a pattern behaves in a Next.js 16 Server Component environment versus a Vite-based Client-side application.

What's Inside
- check_circleFramework switcher — Next.js ↔ Vite per recipe
- check_circleLive interactive demo per pattern
- check_circleSave & bookmark recipes
- check_circleFully typed — TypeScript strict mode
- check_circleFully searchable — ⌘K
menu_bookCookbook
Production patterns,
not just snippets.
Each recipe covers the why, the constraints, the pattern, and a real implementation — side by side for Next.js and Vite.

Foundations
State Taxonomy
Three categories of state — local, shared, and server — and exactly which tool handles each one.

Component Composition
How components combine and communicate — children props, slot patterns, and why composition beats deep prop drilling.

Server State with React Query
Fetch, cache, and synchronize server data with TanStack Query v5. Pagination, search, and background refetching.

Form Validation with Zod
Schema-first validation with React Hook Form and Zod. Type-safe, declarative error messages, zero boilerplate.
