Documentation

Cache data will always be saved to browser localStorage with key '__c_2df2a4ade2936ea5639c79d631a51a08'.

Every time the get method is executed, an expired key check is performed, and if any are found, the key is removed.

• set(key, value, timeToExpire) - Inserts a value into the cache.
• get(key) - Returns an object from the cache.
• getKeys() - Returns the existing keys in the cache object.
• isExpired(key) - Checks if the informed cache key is expired.
• removeKey(key) - Removes a key and its object from the cache.
• verifyExpiredKeys(key) - Checks if a key is expired, if it removes the key.
• clear() - Removes all keys and objects from the cache.
