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.
Architecture First
Decoupled logic that works across different React frameworks.
Production Ready
Battle-tested solutions for state management, data fetching, and forms.
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

Project Structure First
One Next.js codebase with clear boundaries for app routes, feature modules, shared logic, and UI primitives.
Systematic Learning
Every pattern follows a rigid, helpful structure.
The Why
The architectural reason this pattern exists — which problem it solves and what goes wrong without it.
Constraints
A set of immutable rules for implementation to ensure consistency and avoid anti-patterns.
The Core
The pure, abstract implementation — decoupled from any specific feature or framework.
Real World
The same pattern applied to Next.js App Router and Vite side by side. Switch frameworks with one click.
Try It
An interactive sandbox embedded directly in the recipe — no setup, no context switching.
