Frontend State Management

Covers the main state management libraries you'll actually use: Redux Toolkit, Zustand, MobX, and Context API with useReducer. Each reference guide shows complete implementations with TypeScript, async operations, and proper patterns. The skill pushes you toward Redux Toolkit for complex apps and Zustand for simpler cases, which is the right call. Includes slice patterns, middleware setup, and server state sync examples. Good for teams that need a consistent approach across projects or developers who want working examples instead of piecing together docs from four different libraries.

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)
