Request: A way to know when ngStorage is ready

[Sithdown]

A way to know when ngStorage module has effectively loaded localStorage values would be very useful.

I am trying to load some localStorage values as soon as the app loads, but ngStorage isn't ready and returns undefined when looking for a key until some time has passed.

Without a way to know when the library is ready and has loaded the storage, or promises in (as it's asynchronous, if I understood correctly), the library is very unreliable.

Am I doing something wrong? Is there an undocumented way to know the readiness of ngStorage?

There shouldn't be any delay before using it in factories / controllers / providers. As soon as dependencies are resolved and the service is returned it should be ready to read values. Would you mind providing a snippet on how you manage to get undefined values ?

I am using this structure in some services:

.factory('settingsService', function($rootScope, $log, $localStorage){

        var i = {
            'audio': {
                'enabled': true,
                'volume': 1.0,
                'speed': 1.0
            }
        };

        var c = {
            getSettings: function(){
                i = $localStorage.kpAppSettings || i;
                if(!$localStorage.hasOwnProperty('kpAppSettings'))
                {
                    $log.debug('kpAppSettings not initialized. Loading defaults...');
                    $localStorage.kpAppSettings = i;
                    i = $localStorage.kpAppSettings;
                }
                $log.debug('settingsService:ready');
                $rootScope.$broadcast('settingsService:ready',i);
                return i;
            }
        };

        return c;
}

Check this out http://plnkr.co/edit/TDPlG140sgIP5sGOJy2c?p=preview if you can?

First load it tells me it initializes defaults. After a refresh it says it's ready.

Which would be how it should behave, or am I missing something?

Oh, I feel stupid now. It seems you've been my rubberduck; after re-reading the code I saw ngStorage is working well; it just doesn't receive any modification because I assigned it to the wrong variable.

Thank you.

You are most welcome.
