In this lesson we‘ll setup a simple build process for converting our ES6 React components into ES5 using Babel and Webpack
Install:
npm i --save react react-dom
npm i -D babel-loader babel-core babel-preset-es2015 babel-preset-react
npm i -g babel webpack webpack-dev-server
Create files:
touch App.js main.js webpack.config.js
Webpack.config.js:
module.exports = {
entry: ‘./main.js‘,
output: {
path: ‘./‘,
filename: "index.js"
},
devServer: {
inline: true,
port: 3336
},
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /(node_modules|bower_components)/,
loader: ‘babel‘,
query: {
presets: [‘es2015‘, ‘react‘]
}
}
]
}
};

App.js:
import React from ‘react‘;
export default class App extends React.Component {
render() {
return (
<span>Hello React</span>
)
}
}
main.js:
import React from ‘react‘; import ReactDOM from ‘react-dom‘; import App from ‘./App‘; ReactDOM.render(<App />, document.getElementById(‘app‘));
Run:
webpack-dev-server
