5 React State Management Libraries Compared

Choosing a state management library is one of the first - and most important - decisions in a React project. Let me break down the most popular options.

The Contenders

1. Redux - The old guard
2. MobX - The reactive option
3. Zustand - The minimalist
4. Recoil - Facebook's experiment
5. easy-model - The newcomer with IoC

1. Redux

The elephant in the room. Still popular but increasingly seen as over-engineered.

// Action
const increment = () => ({ type: "INCREMENT" });

// Reducer
const counterReducer = (state = 0, action) => {
 switch (action.type) {
 case "INCREMENT":
 return state + 1;
 default:
 return state;
 }
};

// Store
const store = createStore(counterReducer);

// Component
function Counter() {
 const count = useSelector((state) => state);
 const dispatch = useDispatch();

 return <button onClick={() => dispatch(increment())}>{count}</button>;
}

Pros:

• Predictable
• DevTools are amazing
• Huge ecosystem

Cons:

• Boilerplate is insane
• Steep learning curve
• any types everywhere

2. MobX

Reactive, class-based approach.

class Store {
 @observable count = 0;

 @action
 increment() {
 this.count += 1;
 }
}

const store = new Store();

const Counter = observer(() => (
 <button onClick={() => store.increment()}>{store.count}</button>
));

Pros:

• Less boilerplate than Redux
• Class-based (familiar OOP)
• Fine-grained reactivity

Cons:

• TypeScript pain
• Hidden dependencies
• Decorator drama

3. Zustand

Minimalist and fast.

const useStore = create((set) => ({
 count: 0,
 increment: () => set((state) => ({ count: state.count + 1 })),
}));

function Counter() {
 const { count, increment } = useStore();
 return <button onClick={increment}>{count}</button>;
}

Pros:

• Absolutely minimal
• Insanely fast
• Good TypeScript support

Cons:

• No class models
• No dependency injection
• Can't watch nested changes

4. Recoil

Facebook's attempt at something better.

const countAtom = atom({ key: "count", default: 0 });

const countSelector = selector({
 key: "doubleCount",
 get: ({ get }) => get(countAtom) * 2,
});

function Counter() {
 const [count, setCount] = useRecoilState(countAtom);
 return <button onClick={() => setCount((c) => c + 1)}>{count}</button>;
}

Pros:

• Simple API
• Good async support

Cons:

• Not stable (Facebook abandoned it)
• Performance issues at scale
• Hard to debug

5. easy-model

The newcomer that combines the best of all worlds.

class CounterModel {
 count = 0;

 increment() {
 this.count += 1;
 }
}

function Counter() {
 const counter = useModel(CounterModel, []);
 return <button onClick={() => counter.increment()}>{counter.count}</button>;
}

Pros:

• Class-based (like MobX)
• Built-in IoC
• Deep watching
• History/Undo-Redo
• Great TypeScript support

Cons:

• Newer, smaller community
• No Redux DevTools (yet)

Feature Matrix

My Recommendation

• Simple project / local state: Zustand
• Need Redux ecosystem: Redux
• Enterprise / Need IoC: easy-model
• Legacy MobX project: Stay with MobX

For new projects? I'd pick easy-model. It gives you the class model of MobX, the simplicity of Zustand, and adds IoC capabilities that no other library provides.
