React and State Management

As a component-based library, in React, state management is a critical element in application development. State determines how components behave and where they are updated. In general, there are many libraries for state management; in this article, we will examine the advantages of MobX and Zustand.

What is MobX?

MobX is a state management library that works with the reactive programming model. MobX ensures that state changes are automatically reflected in components, which makes the development process simple and effective. With MobX, we can easily implement state management.

How to Use MobX?

To start using MobX, we first need to include the library in our project. You can follow the steps below:

npm install mobx mobx-react

For example, let’s create a simple counter application:

import { observable, action } from 'mobx';
import { observer } from 'mobx-react';

class Counter {
    @observable count = 0;

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

const counter = new Counter();

const CounterComponent = observer(() => {
    return 

        
{counter.count}
         counter.increment()}>Increment
    
;
});

export default CounterComponent;

What is Zustand?

Zustand is a lightweight state management library developed for React applications. By offering a functional API, Zustand makes state management both simple and efficient. It is very easy to use and requires minimal configuration.

How to Use Zustand?

With Zustand, we can quickly create a state store. First, let’s install the library:

npm install zustand

Now, let’s go through an example of a counter application:

import create from 'zustand';

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

const CounterComponent = () => {
    const { count, increment } = useStore();
    return 

        
{count}
        Increment
    
;
};

export default CounterComponent;

Conclusion

MobX and Zustand are two different but effective state management tools for React applications. While MobX provides more complex structures with reactive programming, Zustand offers a simplicity and performance-focused approach. Depending on the needs of your project, you can facilitate your application by choosing one of these libraries.
