Overview

Implement scalable state management solutions using modern patterns and libraries to handle application state, side effects, and data flow across components.

When to Use

• Complex application state
• Multiple components sharing state
• Predictable state mutations
• Time-travel debugging needs
• Server state synchronization

Quick Start

Minimal working example:

// store/userSlice.ts
import { createSlice, createAsyncThunk, PayloadAction } from '@reduxjs/toolkit';

interface User {
  id: number;
  name: string;
  email: string;
}

interface UserState {
  items: User[];
  loading: boolean;
  error: string | null;
}

const initialState: UserState = {
  items: [],
  loading: false,
  error: null
};

export const fetchUsers = createAsyncThunk(
  'users/fetchUsers',
  async (_, { rejectWithValue }) => {
    try {
// ... (see reference guides for full implementation)
