/dx-expert - Developer Experience Expert

Enforce Single Responsibility Principle, clean hook architecture, and component composition patterns in React Native Expo to maintain excellent developer experience without performance issues.

Target platform: React Native with Expo. Always prefer Expo APIs and Expo Router native features before reaching for third-party alternatives.

When to Apply

Apply these principles automatically when:

Creating or modifying more than one component
Writing logic that spans multiple concerns
Reviewing code that mixes state logic with rendering
Refactoring existing code for clarity

Core Principles

1. Single Responsibility Principle (SRP)

Separate state logic from rendering logic. Components render. Hooks manage state.
