I\'m roughly following JavaScript/TypeScript quickstart for Angular2 to write my app in ES6 but can\'t get the decoractor to works
It is because you are using Babel 6 and decorators are currently disabled for it, but you can make it work with the legacy plugin transform-decorators-legacy. The reason for disableing is that the syntax will change in the near future. https://github.com/loganfsmyth/babel-plugin-transform-decorators-legacy
