I have a a helper function that I call when I want to delete something from my redux store. However I need to be able to access the current store inside the function to make a determination on what to do next. Here's what I want to do:
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());
}
}
I call this function from a component and pass the "this" context to it so it will have access to dispatch if you're curious about that. But if I try to reference a prop that I pass along it doesn't update after the "deleteShape" call because this function is not "connected" (for lack of a better word) to the redux store. So my question is this: how can I access the current redux store from non-component functions? Thanks
I must say that I think it's a bad practice to randomly access the store from some function, and some side effects may occur, but if you have to do it this is a possible way:
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());
}
}
