I could not for the life of me find a good example of boilerplate for React with Webpack and loading external data from some kind of API, so I put together the parts with Babel 6, SCSS, hot reloading, and Fetch. (it’s only suitable for local development, though build pieces are started). I hope you find it useful and don’t have to waste a lot of time like I did!
