React + Redux To-Do List Tutorial

Introduction

Managing application state is a critical skill in React development. In this tutorial, you will build a To-Do List application using React and Redux Toolkit, learning how to efficiently manage state in a structured way.

📌 AI Prompt: "What is Redux?"

📌 AI Prompt: "How is Redux different from useState?"

📌 AI Prompt: "What is Redux Toolkit?"

Why Use Redux for a To-Do List?

A basic to-do list can be built using React’s useState, but as applications grow, managing state across multiple components becomes complex. Redux Toolkit provides a centralized way to manage state, ensuring:

  • ✅ A single source of truth for to-dos across components.
  • ✅ Predictable state updates using reducers and actions.
  • ✅ Scalability, allowing easy expansion with filters, priorities, and persistence.

Who is this Tutorial For?

This tutorial is designed for developers who:

  • ✅ Have basic React knowledge (components, useState, useEffect).
  • ✅ Want to learn Redux Toolkit for structured state management.
  • ✅ Are comfortable with JavaScript ES6+ (map, filter, arrow functions`).

What You Will Learn

By the end of this tutorial, you will be able to:

  • ✅ Use Redux Toolkit (configureStore, createSlice) to manage state.
  • ✅ Connect Redux to React using useSelector and useDispatch.
  • ✅ Implement actions and reducers to handle adding, updating, and deleting tasks.
  • ✅ Enhance the to-do app with state persistence, filters, and sorting.

📌 AI Reflection Prompt: "Why might Redux be useful for state management instead of React’s useState?"

Project Overview

Features of the To-Do List App:

  • ✅ Add tasks dynamically.
  • ✅ Mark tasks as completed or active.
  • ✅ Delete tasks.
  • ✅ Display task list from Redux state.
  • ✅ Store tasks persistently (Stretch Goal).

Technologies Used:

  • React for building UI components.
  • Redux Toolkit for state management.
  • React-Redux for connecting Redux to React components.

📌 AI Debugging Prompt: "What happens if I modify state directly in a Redux reducer?"

🚀 Now that you understand the purpose of the tutorial, let’s move on to Project Setup! 🚀
