Clone this repo and then after entering the new directory run npm install.
You'll also need to have gulp installed globally: npm install -g gulp
Run in the root of your directory: gulp watch
This will watch the src directories and build on changes and placed the built css and js files in the public directory. It'll serve everything in the /public directory at localhost:8080
Restart gulp watch and reload your browser.
The problem is that I have Webpack setup to package CSS for the browser but we're using Sass/Compass before Webpack. On the first run, the public/main.css file is empty as Sass hasn't done its thing yet so Webpack requires an empty file and no styles show up in the browser. On the next start of gulp watch the public/main.css file has been compiled by Sass so styles will now show up in the browser.
To build for production, simply run gulp build
