Reading through the GTFS-Realtime, I came across these code samples, with Javascript in the list.

I want to use the package in my angular project. How can I?
gtfs-realtime-bindings is available as node module and you can use nodejs and angularjs in the same project, see i.e. https://scotch.io/tutorials/creating-a-single-page-todo-app-with-node-and-angular <- nice
In this thread is a general way how to include node modules in angular (extract the javascript or browserify): Using node module in angularjs?
