Getting started with a React application
Presentation

Example app
What we'll be using:
- Babel to convert ES2015 JSX files to ES5 files
- Webpack to create a single JS file for the browser
- Webpack dev server to load our web page
To create this project template from scratch:
# Install system-wide prerequisites
npm install -g yarn webpack webpack-dev-server
# Create an app directory
mkdir react-app
cd react-app
# Initialize the app directory
npm init
yarn
# Add required development packages
yarn add -D babel-core babel-preset-react babel-loader
# Add required runtime packages
yarn add react
# Create .babelrc file (just copy-paste this line)
echo -e "{\n \"presets\": [\"react\"]\n}" >.babelrc
# To view the created file:
cat .babelrc
# Create webpack.config.js
# I created a Gist for this at https://gist.githubusercontent.com/joostlubach/30955f971560c06bf77f759442b3515f/raw/194a87ec4732b1b8dc1f482956f2334213b08fcc/webpack.config.js
# Either download it and save it as webpack.config.js in your directory, or if you have wget, type:
wget https://gist.githubusercontent.com/joostlubach/30955f971560c06bf77f759442b3515f/raw/194a87ec4732b1b8dc1f482956f2334213b08fcc/webpack.config.js
# To view the created file:
cat webpack.config.js
# Create an empty src and build directory
mkdir src build
# Create an empty index.js file
echo '' >src/index.js- Now create an
index.htmlpage inside the build directory:
<!doctype html>
<html>
<head>
<title>React example</title>
</head>
<body>
<main></main>
<script type="text/javascript" src="./bundle.js"></script>
<script src="/webpack-dev-server.js"></script>
</body>
</html>
- Finally, start up your web server!
webpack-dev-server --content-base build --inline
