How to return a resolved promise from an AngularJS Service using $q?
How to simply return a pre-resolved promise in AngularJS
Resolved promise:
return $q.when( someValue ); // angularjs 1.2+return $q.resolve( someValue ); // angularjs 1.4+, alias to `when` to match ES6Rejected promise:
return $q.reject( someValue );
Return your promise , return deferred.promise.
It is the promise API that has the 'then' method.
https://docs.angularjs.org/api/ng/service/$q
Calling resolve does not return a promise it only signals thepromise that the promise is resolved so it can execute the 'then' logic.
Basic pattern as follows, rinse and repeat

From your service method:
function serviceMethod() { return $timeout(function() { return { property: 'value' }; }, 1000);}And in your controller:
serviceName .serviceMethod() .then(function(data){ //handle the success condition here var x = data.property });
