Why is Redux Toolkit the new standard?
How to avoid chaos in state management?
Practical: Creating a counter with Redux Toolkit
🔥 Lesson highlights
1️⃣ Why do we need Redux?
Problems without Redux:
🌀 Data updates each other → chaos
🔄 Components trigger chain reactions
🕵️♂️ It's difficult to trace the source of changes
Solution:
✅ Single Store — single source of truth
🔄 Clear data flow (actions → reducers → state)
🛠 Redux DevTools for debugging
2️⃣ Redux vs. Context vs. Local State
3️⃣ Redux Toolkit (RTK) — a modern approach
🚀 Less code (no boilerplate!)
🔧 Built-in best practices
⚡ Automatic handling of immutability
4️⃣ 6 key concepts of Redux
Store — a single state store
Slice — a portion of the state (e.g., userSlice, cartSlice)
Actions — events for State changes
Reducers — pure update functions
Dispatch — dispatching actions
Selectors — receiving data from the Store
💻 Practice: Counter with Redux Toolkit
🔧 What we're doing:
Install @reduxjs/toolkit + react-redux
Create a Store (configureStore)
Write counterSlice (createSlice)
Connect a Provider to React
Using useSelector and useDispatch
