Angular UI-Router - using "resolve" directly on template url

I am using UI-Router and want to change routing to be 'component based'. So Instead of defining a controller / template I want to use it like this:

.state('issue', {
    url: '/someUrl/:number',
    template: '<my-directive></my-directive>',
    resolve: {
      data: function(dataService) {
        return dataService.getData().then(function(response) {
            console.log(response.data);
            return response.data;
        });
      }
    }
 })

Now, I know that with Angular's ngRoute I can use resolved data directly in the template, for example:

 $routeProvider
      .when('/', {
        template: `<my-directive data="resolve.data"></my-directive>`,
        resolve: {
          data: function (dataService) {
            return dataService.getData();
          }
        }
      })

I couldn't do it using UI-Router (value was undefined).

Am I doing something wrong? Is it possible using ui-router?

Actually you can (tested only in ui-router v0.3.2)

There's an undocumented $resolve variable which is automatically injected in the controller. Simply add 'controllerAs' property to the state as follows, and you can use $resolve in the template:

.state('issue', {
    url: '/someUrl/:number',
    template: '<my-directive data="vm.$resolve.data"></my-directive>',
    controllerAs: 'vm',
    resolve: {
      data: function(dataService) {
        return dataService.getData().then(function(response) {
            console.log(response.data);
            return response.data;
        });
      }
    }
 })

If you mean injecting your data service, then you can do it like this (remember that the '' is telling to inject):

state('issue', {
        url: '/someUrl/',
        template: '<my-directive data="pep.data"></my-directive>',
        controller: function( data) { this.data = data },
        controllerAs: 'pep',  
        resolve:{
                 dataSvc : 'YourDataSvc',
                 campaign : function(dataSvc){
                         return dataSvc.getData();

                }
             }

Please remember a ui-view will be expected if you want to put additional views or child states.

The point with UI-Router is - result of resolve is available for a controller (related to template). So, we could do it like this:

.state('issue', {
    url: '/someUrl/:number',
    template: '<my-directive data="stateCtrlData"></my-directive>',
    controller: function($scope, data) { $scope.stateCtrlData = data },
    resolve: {
      data: function(dataService) {
        return dataService.getData().then(function(response) {
            console.log(response.data);
            return response.data;
        });
      }
    }
  })

The data are passed into controller and from its scope we pass it to directive.
