I've setup a [webpack](https://webpack.js.org/) development environment with hot module replacement that you can use to quickly iterate the application.\n- Ensure that you have node and npm installed on your machine. You can follow the official instructions at https://www.npmjs.com/get-npm\n- Clone the repository into your desired project folder\n- Run `npm install` from within the project folder to install dependencies\n- Ensure webpack-cli is either available globally or installed locally (`npm install --save-dev webpack-cli`)\n- Run `npm start`. This will spin up a webpack development server running at http://localhost:8080\n- Change the code you like and see what happens!\n\n## Building\n- Run `npm run build` to build a production ready version of the web app.\n- Contents will be processed into /dist, which you can upload to your web server.\n\n## License\nMIT\n\n## Warranty\nNone whatsoever.\n" }, { "path": "bundle.js", "content":
