Video 1/2/3: https://www.youtube.com/watch?v=G40iHC-h0c0&list=PL55RiY5tL51oyA8euSROLjMFZbXaV7skS&index=4
This works in 2018, webpack 4:
webpack.config.js
const webpack = require('webpack');
module.exports = {
entry: './src/app/index.js',
module: {
rules: [
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
use: ['babel-loader']
}
]
},
resolve: {
extensions: ['*', '.js', '.jsx']
},
output: {
path: __dirname + '/dist',
publicPath: '/',
filename: 'bundle.js'
},
plugins: [
new webpack.HotModuleReplacementPlugin()
],
devServer: {
contentBase: './dist',
hot: true
}
};

Video 5 - PropTypes Notes:
https://reactjs.org/docs/typechecking-with-proptypes.html
Note: React.PropTypes has moved into a different package since React v15.5. Please use the prop-types library instead. We provide a codemod script to automate the conversion.
https://www.npmjs.com/package/prop-types
npm install --save prop-types
import PropTypes from 'prop-types'; // ES6
var PropTypes = require('prop-types'); // ES5 with npm
example:
Home.propTypes = {
age: PropTypes.number,
user: PropTypes.object
};
