Memoization

Since every library call performs one or multiple requests to an iTunes API or web page, sometimes it can be useful to cache the results to avoid requesting the same data twice. The memoized function returns the store object that caches its results:

var store = require('app-store-scraper'); // regular non caching version
var memoized = require('app-store-scraper').memoized(); // cache with default options
var memoizedCustom = require('app-store-scraper').memoized({ maxAge: 1000 * 60 }); // cache with default options

memoized.app({id: 553834731}) // will make a request
  .then(() => memoized.app({id: 553834731})); // will resolve to the cached value without requesting

The options available are those supported by the memoizee module. By default up to 1000 values are cached by each method and they expire after 5 minutes.
