Question

Is there a benefit to using the Angular LocalStorageModule alongside angular-cache?

To configure the angular-cache, follow this setup:

app.service('myService', function ($angularCacheFactory) {

    // This cache will synchronize with localStorage if available. Upon each app load, it will attempt to retrieve any previously saved data from localStorage (or sessionStorage).
    var myAwesomeCache = $angularCacheFactory('myAwesomeCache', {
        maxAge: 900000, // Items in this cache expire after 15 minutes.
        cacheFlushInterval: 3600000, // The cache will clear itself every hour.
        deleteOnExpire: 'aggressive', // Items will be immediately removed upon expiration.
        storageMode: 'localStorage' // The cache syncs with `localStorage`.
    });
});

If the storageMode is set to 'localStorage', then the caching system manages backing up to localstorage on its own.

I am currently using the angular LocalStorageModule for other purposes.

Would there be any benefit in setting up a localStoragePolyfill and utilizing the LocalStorageModule as well?

Answer №1

One of the most effective ways to utilize the Cache in conjunction with LocalStorage is demonstrated in this example: .put(key, value, options)

The key takeaway from this approach is that the third parameter, options, pertains to the settings for a specific key and value pair rather than the entire cache instance.

This method can be invoked as follows:

myAwesomeCache.put('someItem'
  , 'someValue'
  , { storageMode: 'localStorage', storageImpl: myLocalStoragePolyfill });

In this scenario, myLocalStoragePolyfill serves as our local storage wrapper, or we may simply use the built-in handler by passing it like { storageMode: 'localStorage' }

By leveraging this technique, we can efficiently cache stable, unchanging data such as metadata or complex application configurations.

When dealing with elements that are predominantly static, utilizing a standard cache in tandem with localStorage can significantly enhance performance...

NOTE: It's important to distinguish between local storage and memory cache. Local storage stores objects as JSON strings without any methods available.
