Step by Step Redux Guide:
// Step 1: Setup Folders
// Create an actions and a reducers folder. Then add an index.js file in both folders.
// Required dependency installs: axios, redux, react-redux, redux-thunk
************************************************
// Step 2: Create Redux Config File
// @ Root of application create a <config>.js file.
import { createStore } from 'redux';
import reducer from './src/reducers';
const configRedux = () => createStore(reducer);
export default configRedux;
!!-------------------------------!!
// If application requires Asyncronous action creators
import { createStore, applyMiddleware } from 'redux';
import reducer from './src/reducers';
import thunk from 'redux-thunk';
const configRedux = () => createStore(reducer, applyMiddleware(thunk));
export default configRedux;
************************************************
// Step 3: Setup root index.js, or App.js
// Import configRedux() into index.js and wrap <App />
import configRedux from '../configRedux';
import { Provider } from 'react-redux';
const store = configRedux();
// Here you'll wrap App in the ReactDOM render
<Provider store={store}> <App/> </Provider>
// Don't worry... The app is freaking out because we haven't built the reducer yet.
************************************************
// Step 4: Create ../actions/index.js File
// @/actions/index.js
// You'll want to export const any actions then wrap that variable into a function.
export const ACTION_NAME = "ACTION_NAME";
// This is known as the action creator.
export const actionName = payload => ({
type: ACTION_NAME,
payload: payload
});
!!-------------------------------!!
// If application requires Asyncronous actions
import axios from 'axios';
export const ACTION_NAME = "ACTION_NAME";
export const FETCH_SUCCESS = "FETCH_SUCCESS";
export const FETCH_TOGGLE = "FETCH_TOGGLE";
// This is known as the action creator.
export const actionName = () => dispatch => {
dispatch({ type: FETCH_TOGGLE });
axios.get('https://api.kanye.rest/')
.then(res => dispatch({ type: FETCH_SUCCESS, payload: res.data.quote }))
.catch(err => dispatch({ type: FETCH_TOGGLE, payload: err }))
};
************************************************
// Step 5: Create a newReducer
// @/reducers/newReducer
// Create a new reducer and import actions from appropriate action file; in this case it's index.js
import { ACTION_NAME } from "../actions/";
const initialState = {
date: Date.now()
};
const newReducer = (state = initialState, action) => {
switch (action.type) {
case ACTION_NAME:
return {
...state,
date: action.payload
};
default:
return state;
}
};
export default newReducer;
!!-------------------------------!!
// Create a new reducer and import actions from appropriate action file; in this case it's index.js
import { FETCH_TOGGLE, FETCH_SUCCESS } from '../actions/;
const initialState = {
kanyeism: '',
error: '',
isFetching: false
}
const asyncReducer = (state = initialState, action) => {
switch(action.type){
case FETCH_TOGGLE:
return {
...state,
isFetching: !state.isFetching,
error: action.payload ? action.payload : ''
}
case FETCH_SUCCESS:
return {
...state,
kanyeism: action.payload,
isFetching: false,
error: ''
default:
return state;
}
}
export default asyncReducer;
************************************************
// Step 6: Create ../reducers/index.js File
import { combineReducers } from 'redux';
import newReducer from '../reducers/newReducer';
// You'll also need to import any other necessary custom reducers.
export default combineReducers({
newReducer
// Include any other reducers required by your application.
});
************************************************
// Step 7: Consume Data with Hooks
// How to consume the data using hooks within a functional component.
// ! 'RAFC --> Tab' for a new functional component if you're using ES7 extension in VS Code.
import React from "react";
import { useDispatch, useSelector } from "react-redux";
import { actionName } from "../actions/";
const NewComponent = props => {
const store = useSelector(state => state.newReducer);
const dispatch = useDispatch();
return (
<div>
<span>{store.date}</span>
<button onClick={() => dispatch(actionName(`${Date.now()}`))}>
Change Date
</button>
</div>
);
// Use this return for an async component
// return (
// <div>
// {console.log(store)}
// <span>{store.kanyeism}</span>
// <button onClick={() => dispatch(actionName())}>New Kanyeism</button>
// </div>
// );
};
export default NewComponent;
// Import the NewComponent into the root index.js file.

Added a few corrections to the Async code-along.
