Set / Get multiple items about angular-localforage

[billymedia]

What is the most efficient way of storing multiple items? I am using parse.com and want to store data locally which could run into thousands? is localforage ideal for this? i plan to use angular.foreach.

If you don't need to get each item separately you can set an array and get it all in once.
If each item should be independent, you can loop, store each promise in an array and do a $q.all() at the end (if you need to use the promise, otherwise don't bother).
It should work well in modern browsers, but be careful if you have to use local storage because it is synchronous (the lib uses the best storage available, but old browsers like IE8/9 don't support indexedDB / WebSQL, so it will switch to local storage...)
I'm not sure how it would behave (the lib is asynchronous in itself, so it shouldn't freez the browser, but it might make it less responsive). You should try it (you can force the driver to use local storage if you want to test the worse possible scenario).

If I have the time, I'll try to implement this new function this week end to set/get multiple items all in once, it would make your life easier.

Wow, thanks for the response.
I forgot to mention that the app is a phonegap one targeting android and ios only. I am trying to implement a localstorage facility thus reducing calls to parse.com.
I will need to search through records and filter them which i am still undecided on, i.e. store locally and query or query parse.com directly.

I have it storing multiple like so but my test dataset is only 10 records so i need to create a random sample of say, 10k (worst case) and see how it performs:

var events = [];
            angular.forEach(results.models, function(event) {
                this.push({
                    'name'  : event.getName(),
                    'time'  : event.getTime(), 
                    'date'  : event.getDate()
                });
            }, events);
            $localForage.setItem('PublicEvents',events);

If it's for iOS and Android then you shouldn't have a problem, but support either indexedDB or WebSQL which are asynchronous and way better (in terms of performances and storage capacity) than local storage.
If you intend to store all your events in one time (with one key), then it will be super fast (only one write / read).
