TL;DR: Managing state in React can be challenging as apps scale. This guide explores five top React state management libraries, Redux Toolkit, Zustand, MobX, Recoil, and Jotai, to help you build enterprise-grade, performant applications.
Building modern single-page applications with React is exciting, but as your app grows, managing state becomes essential. State isn’t just about form inputs; it includes API responses, application status, and more.
Effective state management ensures your UI stays consistent, responsive, and predictable, even when handling dynamic data, asynchronous calls, and user interactions. Without a clear strategy, scattered states and duplication can lead to complexity and bugs. That’s why leveraging robust libraries for centralized state management is key to creating scalable, high-performance applications with seamless user experiences.
This article examines five React state management libraries, each with its own distinct architecture for building scalable, high-performance applications.
Redux remains a cornerstone of state management in React, built on the Flux architecture introduced by Facebook (Meta). It enforces a predictable, unidirectional data flow by centralizing state in a single store, ensuring that updates occur in a linear, controlled manner. This approach makes complex applications easier to maintain, reduces errors, and keeps UI logic consistent.
Previously, Redux required extensive boilerplate, but Redux Toolkit (RTK) has transformed the experience. RTK simplifies setup, reduces boilerplate, and introduces modern features like hooks, built-in async handling with RTK Query, and seamless TypeScript integration. For enterprise-grade applications that demand scalability, performance, and clarity, Redux Toolkit is a reliable and future-proof choice.
Example
import { createSlice, configureStore } from '@reduxjs/toolkit';
import { useSelector, useDispatch, Provider } from 'react-redux';
// Create a slice
const counterSlice = createSlice({
name: 'counter',
initialState: { value: 0 },
reducers: {
increment: (state) => { state.value += 1 },
decrement: (state) => { state.value -= 1 },
incrementByAmount: (state, action) => { state.value += action.payload; }
}
});
// Configure store
const store = configureStore({
reducer: { counter: counterSlice.reducer }
});
// Component usage
function Counter() {
const count = useSelector((state) => state.counter.value);
const dispatch = useDispatch();
return (
<div>
<h1>{count}</h1>
<button onClick={() => dispatch(counterSlice.actions.increment())}>Increment</button>
<button onClick={() => dispatch(counterSlice.actions.decrement())}>Decrement</button>
</div>
);
}
// App wrapper
function App() {
return (
<Provider store={store}>
<Counter />
</Provider>
);
} Zustand is a small, fast, and scalable state management tool that follows the principles of the Flux architecture while leveraging hooks to simplify state management. It offers a minimal API and eliminates the need for boilerplate or wrapping the application with a Provider, making it an excellent choice for integration with existing state management tools without conflict.
Example
import create from 'zustand';
// Create store
const useStore = create((set) => ({
count: 0,
increment: () => set((state) => ({ count: state.count + 1 })),
decrement: () => set((state) => ({ count: state.count - 1 })),
reset: () => set({ count: 0 })
}));
// Component usage
function Counter() {
const count = useStore((state) => state.count);
const increment = useStore((state) => state.increment);
const decrement = useStore((state) => state.decrement);
return (
<div>
<h1>{count}</h1>
<button onClick={increment}>Increment</button>
<button onClick={decrement}>Decrement</button>
</div>
);
} MobX applies reactive programming principles to state management, offering an alternate approach where components observe state and automatically react to changes. This makes state updates implicit and seamless. By using observable state and automatic dependency tracking, MobX enables efficient state management at scale with a simple API.
Mobx only re-renders the components that are directly affected by state changes, resulting in superior performance in applications with complex state relations.
Example
import { makeObservable, observable, action, computed } from 'mobx';
import { observer } from 'mobx-react-lite';
// Create store class
class CounterStore {
count = 0;
constructor() {
makeObservable(this, {
count: observable,
increment: action,
decrement: action,
doubleCount: computed
});
}
increment() {
this.count++;
}
decrement() {
this.count--;
}
get doubleCount() {
return this.count * 2;
}
}
const counterStore = new CounterStore();
// Component usage
const Counter = observer(() => {
return (
<div>
<h1>{counterStore.count}</h1>
<h2>Double: {counterStore.doubleCount}</h2>
<button onClick={() => counterStore.increment()}>Increment</button>
<button onClick={() => counterStore.decrement()}>Decrement</button>
</div>
);
}); Jotai builds on Recoil’s principles, using atoms (units of state) and selectors to create a graph-based approach to state management in React. It supports concurrent state modifications and asynchronous queries, integrating smoothly with React Suspense for performance-sensitive applications.
Jotai also addresses limitations in Redux and MobX by improving derived data handling and cross-component synchronization.
Example
import { atom, useAtom, useAtomValue, useSetAtom } from 'jotai';
// Define atoms
const countAtom = atom(0);
const doubleCountAtom = atom((get) => get(countAtom) * 2);
// Component usage
function Counter() {
const [count, setCount] = useAtom(countAtom);
const doubleCount = useAtomValue(doubleCountAtom);
return (
<div>
<h1>Count: {count}</h1>
<h2>Double: {doubleCount}</h2>
<button onClick={() => setCount(count + 1)}>Increment</button>
</div>
);
}
// Advanced: Async atoms
const userAtom = atom(async (get) => {
const userId = get(userIdAtom);
const response = await fetch(`/api/users/${userId}`);
return response.json();
});
// Write-only atom
const decrementAtom = atom(
null,
(get, set) => set(countAtom, get(countAtom) - 1)
);
function DecrementButton() {
const decrement = useSetAtom(decrementAtom);
return <button onClick={decrement}>Decrement</button>;
} Recoil is a state management library developed by Facebook, designed specifically for React. It introduces atoms (units of state) and selectors (derived/computed state), enabling fine-grained reactivity and seamless integration with React’s concurrent features like Suspense.
Example
# Install Recoil
npm install recoil
// state.js
import { atom } from 'recoil';
export const counterState = atom({
key: 'counterState', // unique ID
default: 0, // default value
});
// Counter.js
import React from 'react';
import { useRecoilState } from 'recoil';
import { counterState } from './state';
function Counter() {
const [count, setCount] = useRecoilState(counterState);
return (
);
}
export default Counter;
// index.js (React 18)
import React from 'react';
import ReactDOM from 'react-dom/client';
import { RecoilRoot } from 'recoil';
import Counter from './Counter';
const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
