如何在Angular.js服务中正确包装GAE Channel API并将更新推送到整个应用程序？

Question

So I'm trying to use the GAE Channel API with Angular.js to do real-time data-bound updates (which would be really cool, right!?). I'm told the correct way to do this is to wrap the Channel API Javascript Client in an Angular.js service ( and make sure to use $apply() ). But what does that mean exactly?

To my understanding, for the Channel API, I'm pretty much supposed to have a 1:1 client:channel connection, so all my updates will have to flow down that one channel for all the models in my entire app. How do I then broadcast to possibly multiple scopes that a model (generally an ngResource) has been updated? $watch? $emit? $broadcast? $digest?

I had the same requirement and solved it with an Angular service. I described my solution here :
