前段时间用的redux，发现用起来非常麻烦，自己会用了也很难教会别人，昨天看了下mobx，用法如下 先定义一个类似于store的东西

import { observable } from 'mobx'
import { topicListApi } from '../config/api';

class topicStore {
    @observable 
    topic = {
        data: [],
        page: 1,
        tab: ''
    }

    constructor () {
       this.getData()
    }

    getData = () => {
		const { tab, page } = this.topic
		topicListApi(page, tab).then((data: any) => {
			if (data.success) {
                this.topic = {
                    ...this.topic,
                    data: data.data
                }
			}
		})
    }
    
    filter = (tab: string) => {
		this.topic.tab = tab
        this.getData()
	}

	flip = (page: number) => {
		this.topic.page = page
        this.getData()
	}
}

export default new topicStore();

然后在react组件内部

import {observer} from 'mobx-react';
import topicStore from '../../mobx/topic'

@observer
class TopicIndex extends React.Component<{}, any> {
render() {
...
	{topicStore.topic.data.map((topic: topicObject, index: number) => {
			return this.topicTemplate(topic, index)
	})}
}
...

我就直接拿来用了，不像redux要绑定props，这样当store里的值发生变化，组件会自动刷，直接绕过react组件的state和props, 我想问下，这是正确用法吗？
