$routeProvider - Injecting same dependency for all routes
Question
The following code:
$routeProvider .when("/page1", { controller: "MyController", resolve: {Strategy: "StrategyOne"}})
waits for the Strategy dependency to be resolved before to instantiate the controller "MyController".
In my application I have a function which returns a promise, which when resolved, gives the current user. Let's called that function Authentication.currentUser()
I would like all the pages of my app to wait for that promise to be resolved before to render a page. I could happily add a line for each route declaration but I would rather avoid duplication.
I have a controller called 'MainCtrl' which is called for all pages thanks to this line in my template:
<html ng-app="clientApp" ng-controller="MainCtrl">
I think one possible way to address this would be if it was possible to specify Authentication.currentUser() as a dependency of "MainCtrl" at the controller level (not at the route level because this dependency does not depend on a particular route).
Thanks for your help guys!

For those who want to address this with the standard $routeProvider, this is what I came out with:
$rootScope.$on('$routeChangeStart', function (event, next, current) {
if (!next.resolve){ next.resolve = {} }
next.resolve.currentUser = function(Authentication){
return Authentication.currentUser();
};
});

If you can move from the default router, to ui-router , then you can do this with nested states. Just copying the example from https://github.com/angular-ui/ui-router/wiki/Nested-States-%26-Nested-Views#inherited-resolved-dependencies :
$stateProvider.state('parent', {
resolve:{
resA: function(){
return {'value': 'A'};
}
},
controller: function($scope, resA){
$scope.resA = resA.value;
}
})
.state('parent.child', {
resolve:{
resB: function(resA){
return {'value': resA.value + 'B'};
}
},
controller: function($scope, resA, resB){
$scope.resA2 = resA.value;
$scope.resB = resB.value;
}
