Redux Toolkit State Management

Manage complex application state with Redux Toolkit, the official recommended approach for writing Redux logic.

Overview

Redux Toolkit (RTK) is the official, batteries-included way to write Redux logic. It eliminates boilerplate with utilities like `createSlice`, `createAsyncThunk`, and RTK Query for data fetching. AI agents can scaffold entire Redux architectures, generate slices, implement async operations, and set up normalized state with entity adapters.

RTK includes Immer for immutable updates (write mutating logic that produces immutable state), built-in Thunk middleware for async operations, and RTK Query for powerful data fetching and caching. Your AI agent can generate complete CRUD slices with optimistic updates, implement pagination, and set up WebSocket-based real-time state synchronization.

For large-scale applications with complex state requirements, RTK provides the structure and predictability that simpler solutions lack. AI agents can help you implement advanced patterns like code-split reducers, middleware chains, and selector memoization with `createSelector`.

Who Is This For?

Enterprise teams managing complex global state across large applications
Developers implementing data fetching and caching with RTK Query
Engineers building applications with real-time state synchronization
Teams migrating legacy Redux code to Redux Toolkit patterns

Installation

Setup for Claude Code

npm install @reduxjs/toolkit react-redux

Configuration

// store.ts
import { configureStore } from "@reduxjs/toolkit";
import { apiSlice } from "./features/api/apiSlice";
import counterReducer from "./features/counter/counterSlice";

export const store = configureStore({
  reducer: {
    counter: counterReducer,
    [apiSlice.reducerPath]: apiSlice.reducer,
  },
  middleware: (getDefault) => getDefault().concat(apiSlice.middleware),
});
