Redux thunk and react redux

npm i --save redux react-redux redux-thunk // You will need these redux packages

what is redux thunk

Redux Thunk is middleware that allows you to return functions,
rather than just actions, within Redux. 
This allows for delayed actions, including working with promises.

---
One of the main use cases for this middleware is 
for handling actions that might not be synchronous, 
for example, using axios to send a GET request. 
Redux Thunk allows us to dispatch those actions asynchronously 
and resolve each promise that gets returned.

React Redux Thunk

import { createStore, applyMiddleware, compose } from "redux";
import rootReducer from "../reducers/index";
import { forbiddenWordsMiddleware } from "../middleware";
import thunk from "redux-thunk";

const storeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

const store = createStore(
  rootReducer,
  storeEnhancers(applyMiddleware(forbiddenWordsMiddleware, thunk))
);

export default store;

redux thunk

import { createStore, applyMiddleware } from 'redux';
import thunk from 'redux-thunk';
import rootReducer from './reducers/index';

// Note: this API requires redux@>=3.1.0
const store = createStore(rootReducer, applyMiddleware(thunk));
