#172 Redux vs Redux Toolkit

Difference Between Redux and Redux Toolkit

---

🧠 1. Definition

• Redux: A state management library that provides a predictable way to manage application state.
• Redux Toolkit (RTK): An official, opinionated set of tools to simplify Redux development.

---

⚡ 2. Boilerplate Code

• Redux: Requires a lot of setup — creating actions, action types, reducers, and store manually.
• RTK: Reduces boilerplate with built-in utilities like createSlice, configureStore, and createAsyncThunk.

---

🧾 3. Store Configuration

• Redux: You manually combine reducers and apply middleware.
• RTK: configureStore() comes with sensible defaults like redux-thunk and devtools support.

---

🧩 4. Reducers and Actions

• Redux: You create action types, actions, and reducers separately.
• RTK: createSlice() automatically generates actions and reducers together.

// RTK Example
const counterSlice = createSlice({
  name: 'counter',
  initialState: 0,
  reducers: {
    increment: (state) => state + 1,
  },
});

---

🚀 5. Async Handling

• Redux: You manually use middleware like Redux Thunk.
• RTK: Provides createAsyncThunk() to simplify async logic.

---

🧰 6. Community & Support

• Redux: Older, widely adopted but more manual.
• RTK: Officially recommended by the Redux team for new projects.

---

✅ In short:

• Use Redux when you want full manual control.
• Use Redux Toolkit for faster setup, less boilerplate, and built-in best practices.

👉 Most modern React projects use Redux Toolkit now.
