Is CacheFactory in angularjs a singleton?

Question

I\'ve created a service using the CacheFactory. I was expecting it to be a singleton. I inject it into my controller and it works fine within the scope of the controller. Bu

$cacheFactory is actually not the service you want to use - it's a factory that you use to create the singleton service you want to use. Eyeballing your code, it seems like it should work. But I went ahead and created a demo to prove that it does. Here's the service:

.factory('CacheService', function($cacheFactory) {
   var cache = $cacheFactory('cacheService', {
     capacity: 3 // optional - turns the cache into LRU cache
   });

   return cache;
});

In this example, CacheService is the singleton that has a local cache created with $cacheFactory, which is what we return from the service. We can inject this into any controller we want and it will always return the same values.
