React Setting Up React Environment

We want to be able to compile below component and render it in our webpage

Filename: src/index.jsx

import React from 'react';
import ReactDOM from 'react-dom';
class ToDo extends React.Component {
 render() {
 return (<div>I am working</div>);
ReactDOM.render(<ToDo />, document.getElementById('App'));

Install all dependencies

# install react and react-dom
$ npm i react react-dom --save
# install webpack for bundling
$ npm i webpack -g
# install babel for module loading, bundling and transpiling
$ npm i babel-core babel-loader --save
# install babel presets for react and es6
$ npm i babel-preset-react babel-preset-es2015 --save

Configure webpack

Create a file webpack.config.js in the root of your working directory
Filename: webpack.config.js

module.exports = {
 entry: __dirname + "/src/index.jsx",
 devtool: "source-map",
 output: {
 path: __dirname + "/build",
 filename: "bundle.js"
 module: {
 loaders: [
 {test: /\.jsx?$/, exclude: /node_modules/, loader: "babel-loader"}
