Hi Olivier Clément,
You just need it in a couple of places? I would use an callback system,
something like this:
```javascript
angular.service('demo', [
'',
function () {
var callbacks = [];
var me = this;
var resizeHandler = function () {
this.size = {
height: $win.height()
}
callbacks.foreach(function (cb) {
cb(me);
})
}
this.register = function (cb) {
callbacks.push(cb);
}
angular.element($window).bind('resize', resizeHandler);
}
])
```
This is obviously not production ready, but it should get you going. You
need to add an deregister to prevent memory leaks, and for a resize event,
I would also add debouncing.
I would do it this way, because all resize callbacks will get called in 1
digest loop. I think adding watches for this is indeed a bit too costly.
The same goes for (although slightly less) using broadcast events.
Regards
Sander
