How to bind server side events on client objects and vice versa with meteor

Is it possible to directly bind server side events to client side objects in meteor?

I would like to update a view for example when a server side event triggers. On the other hand I'd like to fire a server side method when a user clicks a view item.

I could use Meteor#methods for all the events but that seems odd.

Or can I specify an eventhandler for example using EventEmitter outside the client- and server-scope so that it is available on both sides and trigger/bind events ob that very object?

Some confused about that I am thankful for hints into the right direction.

Regards Felix

Update:

Using Meteor#methods works great in case user events should be mapped to server side actions. The other way around is still unclear. Asynchronous actions on serverside could persist their results in a collection which is pub/sub'ed to the client, which in turn could update some view due to the reactive context. But thats odd, cause persisting that kind of info is slow, wasted space and time. Any suggestions?

What about storing the progress in Session? You could do something like this:

Template.progress.value = function() {
    return Session.get('progress');
}

Then, whenever you update the Session on the server, the client template will automatically get those changes.

Out of curiosity, how exactly are you performing asynchronous actions on the server? I'm still trying to figure that out.

I believe you can use the Collection.observe on the server side to 'observe' events on the Collection as clients are inserting, updating, removing, etc... That might be a start if you are focused on Collections alone. I used it like a sort of server side event loop to watch for collection changes.

When a user clicks on something in a view try binding a Template Event to the View css selector and then calling a Meteor method which will notify the server of the event. See the examples of binding a key handler and/or button handlers to a Template.entry.event which then call a Meteor method notifying the server that something happened.
