Modern Front‑End Architecture: React + Redux

Published: September 14 2025 • Author: Jane Doe

Why React?

React provides a component‑driven approach that encourages reusability, declarative UI, and a virtual DOM for high performance. Its ecosystem – from hooks to concurrent mode – makes it an ideal foundation for modern, scalable front‑ends.

Redux Overview

Redux centralises application state, making it predictable and easier to debug. With the @reduxjs/toolkit package, boilerplate is dramatically reduced.

Project Setup

npx create-react-app modern-frontend --template typescript
cd modern-frontend
npm i @reduxjs/toolkit react-redux
npm i -D @types/react-redux

State Management Pattern

We use a feature‑slice approach. Each slice contains its own reducer, actions, and selectors, keeping the store modular.

Live Code Example

Below is an interactive counter built with React and Redux Toolkit. Edit the code and see changes instantly.

Best Practices

• Keep state as flat as possible.
• Prefer immutable updates (use RTK’s Immer integration).
• Separate UI logic from business logic via custom hooks.
• Use React.memo and useSelector with shallow equality where appropriate.
• Leverage TypeScript for type‑safe actions and selectors.
