Hey all,

Before I make a change to this polyfill I wanted to make sure there were no concerns or objections. Basically, what I want to do is change the usage so that calls to navigator.push.register() or navigator.push.registrations() (not yet added) would have to be done after a connection is established.

Currently, a user can call either of those methods at any time which causes headaches when trying to account for registrations that happen before the connection and also register previously used channels stored in localStorage. Just as an FYI, this is not an issue for Mozilla because they already know they have a connection when their JS executes because the browser creates the connection during startup.

I have done a LOT of work to try to account for race conditions which may occur and in the process added a LOT of extra code.

And even with all of that work, I'm still not 100% sure that all race conditions have been accounted for once this code is used at scale with lots of connec!
 tions.

So what am I suggesting? I would like to require our users to create a connection to the SimplePush server and do their interactions with that server in the success (or onConnect or what ever we want to call it) callback.

After that, all code would be identical to the Mozilla APIs.

Then, we could just write a brief guide or tutorial on transitioning code between our implementation and Mozilla's to highlight the small difference.

Thoughts?
