Add the react-hot-loader to your create-react-app app via react-app-rewired.

Because who wants their app, state, and styles automatically reloading all the time?

npm install --save react-app-rewire-hot-loader

# If you don't already, you also need:
npm install --save react-app-rewired
npm install --save react-hot-loader

1. In the config-overrides.js of the root of your project you created for react-app-rewired add this code:

const rewireReactHotLoader = require('react-app-rewire-hot-loader')

/* config-overrides.js */
module.exports = function override (config, env) {
  config = rewireReactHotLoader(config, env)
  return config
}

2. Follow 'step 2' from https://github.com/gaearon/react-hot-loader , replicated below:

Mark your root component as hot-exported:

// App.js - react-hot-loader >= 4.5.4
import React from 'react'
import { hot } from 'react-hot-loader/root'

const App = () => <div>Hello World!</div>

export default process.env.NODE_ENV === "development" ? hot(App) : App

Old version: Prior to react-hot-loader version 4.5.4. you needed to write hot(module)(App).

react-hot-loader recommends to use the latest syntax as "it is much more resilient to js errors you may make during development."

// App.js - react-hot-loader < 4.5.4
import React from 'react'
import { hot } from 'react-hot-loader'

const App = () => <div>Hello World!</div>

export default process.env.NODE_ENV === "development" ? hot(module)(App) : App

3. Replace 'react-scripts' with 'react-app-rewired' in package.json

  "scripts": {
    "start": "react-app-rewired start",
    "build": "react-app-rewired build",
    "test": "react-app-rewired test --env=jsdom",
    "eject": "react-app-rewired eject"
  },

That's it, you now have hot reloads!
