MobX vs. Redux: Why MobX Might Be the Better Choice for Your Next Project

#javascript #tutorial #learning #webdev

State management can be a scary concept, especially for those new to coding. But fear not, because MobX is here to make things a whole lot easier! With its straightforward approach and effortless optimal rendering, MobX simplifies state management in ways you never thought possible.

What is MobX?
MobX is a state management library that makes state management simple and scalable by using reactive programming. It allows you to create observable state that automatically updates the UI whenever the state changes. MobX is known for its minimal boilerplate and ease of use, which can significantly speed up development time.

What is Redux?
Redux is another popular state management library, particularly well-known in the React ecosystem. It uses a unidirectional data flow and requires actions, reducers, and a central store to manage the state. Redux is praised for its predictability and the way it structures state updates, but it can involve a lot of boilerplate code and a steeper learning curve.

Key Differences Between MobX and Redux

Boilerplate Code One of the most significant differences between MobX and Redux is the amount of boilerplate code required.

Learning Curve Redux has a steeper learning curve due to its strict structure and the need to understand concepts like actions, reducers, and middleware. MobX, on the other hand, is more intuitive and easier to learn, especially for developers new to state management.

Flexibility vs. Predictability MobX: Offers more flexibility and less boilerplate. It allows you to write code in a way that feels natural without enforcing strict patterns. This can lead to faster development times and less frustration for developers. Redux: Provides predictability and a clear structure that can be beneficial for large teams and complex applications. The unidirectional data flow and strict patterns help maintain consistency, but at the cost of increased complexity.

Redux Example
In Redux, you need to define actions, reducers, and a store:

Actions (actions.js):

export const increment = () => ({
    type: 'INCREMENT'
});

Reducer (reducer.js):

const initialState = { count: 0 };

const counterReducer = (state = initialState, action) => {
    switch (action.type) {
        case 'INCREMENT':
            return { ...state, count: state.count + 1 };
        default:
            return state;
    }
};

export default counterReducer;

Store (store.js):

import { createStore } from 'redux';
import counterReducer from './reducer';

const store = createStore(counterReducer);

export default store;

Component:

import React from 'react';
import { useDispatch, useSelector } from 'react-redux';
import { increment } from './actions';

const Counter = () => {
    const dispatch = useDispatch();
    const count = useSelector(state => state.count);

    return (
        <div>
            <p>Count: {count}</p>
            <button onClick={() => dispatch(increment())}>Increment</button>
        </div>
    );
};

export default Counter;

MobX Example
In contrast, MobX requires much less boilerplate:

Store (CounterStore.js):

import { makeAutoObservable } from "mobx";

class CounterStore {
    count = 0;

    constructor() {
        makeAutoObservable(this);
    }

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

const counterStore = new CounterStore();
export default counterStore;

Component:

import React from "react";
import { observer } from "mobx-react-lite";
import counterStore from "./CounterStore";

const Counter = observer(() => (
    <div>
        <p>Count: {counterStore.count}</p>
        <button onClick={() => counterStore.increment()}>Increment</button>
    </div>
));

export default Counter;
