What is mobx-react?

The mobx-react package provides React bindings for MobX, a state management library. It allows you to connect your React components to MobX observables, making it easier to manage and react to state changes in your application.

What are mobx-react's main functionalities?

Observer Component

The observer function is used to create a reactive component that will automatically re-render when the observed state changes.

import React from 'react';
import { observer } from 'mobx-react';
import { observable } from 'mobx';

const appState = observable({
  count: 0
});

const Counter = observer(() => (
  <div>
    <button onClick={() => appState.count++}>Increment</button>
    <p>{appState.count}</p>
  </div>
));

export default Counter;

Injecting Stores

The inject function is used to inject stores into components, making it easier to access MobX stores within your React components.

import React from 'react';
import { Provider, inject, observer } from 'mobx-react';
import { observable } from 'mobx';

class Store {
  @observable count = 0;
}

const store = new Store();

const Counter = inject('store')(observer(({ store }) => (
  <div>
    <button onClick={() => store.count++}>Increment</button>
    <p>{store.count}</p>
  </div>
)));

const App = () => (
  <Provider store={store}>
    <Counter />
  </Provider>
);

export default App;

Using MobX with React Hooks

The useLocalObservable hook is used to create local observable state within a functional component, allowing you to use MobX with React hooks.

import React from 'react';
import { useLocalObservable, observer } from 'mobx-react';

const Counter = observer(() => {
  const state = useLocalObservable(() => ({
    count: 0,
    increment() {
      this.count++;
    }
  }));

  return (
    <div>
      <button onClick={state.increment}>Increment</button>
      <p>{state.count}</p>
    </div>
  );
});

export default Counter;
