#98 Difference between Redux vs Redux Toolkit

Redux vs Redux Toolkit (RTK):

---

🔸 Redux (Traditional)

• 🔹 Requires manual setup of store, reducers, and middleware.
• 🔹 Actions and reducers have a lot of boilerplate code.
• 🔹 Uses combineReducers, createStore, and applyMiddleware.
• 🔹 Doesn’t include built-in support for async logic like thunks.
• 🔹 Developers often write types, actions, and reducers separately.

🔸 Redux Toolkit (RTK)

• ✅ Official, recommended way to use Redux.
• ✅ Comes with utilities like:
  • configureStore() – sets up store with good defaults.
  • createSlice() – automatically creates actions and reducers.
  • createAsyncThunk() – handles async logic.
• ✅ Reduces boilerplate significantly.
• ✅ Has Immer.js under the hood → allows mutating state directly.
• ✅ Better developer experience and fewer chances of mistakes.
• ✅ Built-in Redux DevTools integration and default middleware.

✅ Summary:

Feature	Redux	Redux Toolkit
Boilerplate	High	Very Low
Async Support	Manual setup needed	Built-in (createAsyncThunk)
Setup Complexity	More complex	Simplified (configureStore)
Recommended by Redux Team	❌	✅ Yes
