The difference between mobx and redux in React and description

React is a popular JavaScript library for building user interfaces.

State management is an important topic in the React ecosystem, and MobX and Redux are two commonly used state management libraries.

1. Introduction

1.1 MobX

MobX is a simple, scalable and efficient state management library.

It uses observable data structures to automatically track and update states and integrate seamlessly with React.

MobX enables state changes to automatically reflect on related components in a responsive manner, thus achieving easy state management.

1.2 Redux

Redux is a predictable state management container.

It uses a single global state tree to store the state of the application and handles state updates through pure functions (reducers).

Redux follows strict data flow rules, making state changes traceable and predictable, making it easier to debug and test.

2. Difference comparison

2.1 Data flow model

In MobX, the change of state is achieved through the observer mode.

When the state changes, the observer (i.e., the component) is automatically updated.

MobX's data flow is relatively flexible and can directly modify the state inside the component.

In Redux, state changes are triggered by dispatching actions.

An action will be passed to a pure function reducer, and the reducer will return a new state according to the action type.

Redux's data flow is processed strictly in a certain order, so that state changes can be traced.

2.2 Learning curve and complexity

Relatively speaking, MobX is easier for beginners to learn and use.

Its syntax is concise and more intuitive to use, without too many concepts and limitations.

Redux may take some time for beginners to understand its basic concepts and design patterns, and has more advantages for large and complex applications.

2.3 Ecosystem

Redux has a huge ecosystem with many supporting middleware, tools and plug-ins to choose from.

This allows developers to expand and customize Redux more flexibly.

MobX's ecosystem is relatively small, but there are some commonly used extensions and tools available.

2.4 Performance

Performance is an important consideration.

Since MobX uses observer mode, it can be optimized based on the specific situation and updates only those observed states.

This makes MobX more efficient than Redux in some scenarios.

Redux handles state updates strictly in order, so performance tuning may be easier in large applications.

3. Sample code

3.1 MobX Example

import { observable, action } from 'mobx';

class CounterStore {
  @observable count = 0;

  @action increment() {
    ++;
  }

  @action decrement() {
    --;
  }
}

const counterStore = new CounterStore();

export default counterStore;

3.2 Redux example

import { createStore } from 'redux';

const initialState = { count: 0 };

function counterReducer(state = initialState, action) {
  switch () {
    case 'INCREMENT':
      return { count:  + 1 };
    case 'DECREMENT':
      return { count:  - 1 };
    default:
      return state;
  }
}

const store = createStore(counterReducer);

export default store;

4. React Hooks

React Hooks is an important feature introduced in React version 16.8, which makes it more convenient to use state and other React features in function components.

Hooks provides a series of functions, such as useState and useEffect, to manage the state and side effects of components.

React Hooks can be used with MobX and Redux for more flexible and maintainable state management.

With useState, local state can be easily created and updated in function components.

Using useEffect can handle side effects such as data acquisition and subscription.

One of the benefits of using Hooks is that it avoids the tedious layer-by-layer nesting of high-order components and container components.

It makes component logic more centralized and readable and allows better organization and reuse of code.

The above is personal experience. I hope you can give you a reference and I hope you can support me more.
