This is a simple demonstration of how webpack and babel work together to bundle a very simple static react page that should be compatible with old browsers.
Clone and install all dependencies with npm i.
Run npm run dev to run development mode.
This will bundle the source files and start a webpack-dev-server which serves the complete dist folder at http://localhost:9898/.
Run npm run build to bundle the source files without serving the dist folder.
Run npm run build:prod to do the same while adding minification to the process.
