如何从非组件辅助函数访问redux的存储？

Question

当我想从我的redux商店中删除一些东西时,我有一个帮助函数.但是,我需要能够访问函数内的当前存储,以确定下一步该做什么.这就是我想要做的事情:

export function deleteDocument (id) {
    this.props.dispatch(deleteShape({id}));

    const getStore = getStore(); //<-- I need something like this

    if(getStore.documents && !getStore.documents.find(doc => doc.selected)){
        this.props.dispatch(makeTopDocumentSelected());
    }
}

我从一个组件中调用此函数并将"this"上下文传递给它,以便在您对此感到好奇时可以访问dispatch.但是,如果我尝试引用我传递的道具,它在"deleteShape"调用之后不会更新,因为此函数没有"连接"(缺少更好的词)到redux存储.所以我的问题是:如何从非组件函数访问当前的redux存储？谢谢

我必须说我认为从某个函数中随机访问商店是一种不好的做法,但如果你必须这样做,这是一种可能的方法:

file:storeProvider.js

var store = undefined;

export default {
    init(configureStore){
        store = configureStore();
    },
    getStore(){
        return store;
    }
};

file:App.js

import { createStore } from 'redux';
import rootReducer from './rootReducer';
import storeProvider from './storeProvider';

const configureStore = () => createStore(rootReducer);
storeProvider.init(configureStore);
const store = storeProvider.getStore();

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

file:yourfunction.js

import storeProvider from './storeProvider';

export function deleteDocument (id) {
    this.props.dispatch(deleteShape({id}));

    const state = storeProvider.getStore().getState();

    if(state.documents && !state.documents.find(doc => doc.selected)){
        this.props.dispatch(makeTopDocumentSelected());
    }
}
