What are some examples of using MobX with TypeScript?

MobX is a state management library that works well with TypeScript. Here are a few examples:

1. Simple Counter: A basic counter app using MobX to manage the state of the counter value.
2. Todo List: A todo application where you can add, remove, and toggle tasks using MobX for state management.
3. Form Handling: Managing form state and validation with MobX, allowing for reactive updates.

Can you show me the code for a simple counter example?

Sure! Here's a simple counter example using MobX with TypeScript:

import { makeAutoObservable } from 'mobx';

class Counter {
    count = 0;

    constructor() {
        makeAutoObservable(this);
    }

    increment() {
        this.count++;
    }

    decrement() {
        this.count--;
    }
}

const counter = new Counter();
export default counter;

How do I connect this counter to a React component?

You can connect the MobX counter to a React component using the observer function from mobx-react-lite. Here's an example:

import React from 'react';
import { observer } from 'mobx-react-lite';
import counter from './Counter';

const CounterComponent = observer(() => {
    return (
        <div>
            <h1>{counter.count}</h1>
            <button onClick={() => counter.increment()}>Increment</button>
            <button onClick={() => counter.decrement()}>Decrement</button>
        </div>
    );
});

export default CounterComponent;

What are the benefits of using MobX with TypeScript?

Using MobX with TypeScript provides several benefits:

1. Type Safety: Ensures that your state and actions are type-checked, reducing runtime errors.
2. Better Autocompletion: IDEs can provide better autocompletion and hints due to TypeScript's static typing.
3. Clearer Code Structure: Helps in maintaining a clear structure in your state management, making it easier to understand and maintain.
