Clean React: Logic Meets UI
Created by Utsav Chokshi
Learn how to structure React apps so that UI and business logic live in harmony. By the end, you’ll design smart-dumb components, extract reusable hooks and services, and write isolated unit tests that keep your codebase robust and maintainable.
Requirements
- Fundamental JavaScript ES6 syntax
- Basic React functional components and hooks (useState, useEffect)
- Familiarity with npm and running tests
What you'll learn
- Design React components that strictly separate presentation and business logic.
- Create reusable custom hooks and service modules for data and rules.
- Implement Redux selectors and context injection to decouple UI from state and services.
