import { Storage } from 'simple-storage-tools';

enum StorageKeys {
    KEY1 = 'fist-storage',
    KEY2 = 'second-storage',
    localKey = 'key-for-local-storage',
    sessionKey = 'key-for-session-storage'
}

/**
 * this is equal to:
 * sessionStorage.setItem('key-for-session-storage', 'Hello World');
 */
Storage.set(StorageKeys.sessionKey, 'Hello World');

/**
 * this is equal to:
 * console.log(sessionStorage.getItem('key-for-session-storage'));
 */
console.log(Storage.get(StorageKeys.sessionKey)); // print Hello World in console
// you can check the localStorage (it will be null with this key)
console.log(Storage.get(StorageKeys.sessionKey, true)); // print undefined

// this example is for using localStorage instead of sessionStorage

/**
 * this is equal to:
 * localStorage.setItem('key-for-local-storage', 'Hello World');
 */
Storage.set(StorageKeys.localKey, 'Hello World', true);

/**
 * this is equal to:
 * console.log(localStorage.getItem('key-for-local-storage'));
 */
console.log(Storage.get(StorageKeys.localKey, true)); // print Hello World in console
// you can check the sessionStorage (it will be null with this key)
console.log(Storage.get(StorageKeys.localKey));


// this example is for putting json as an arguman

const json = {
    value1: 'Hello',
    value2: 'World'
};

// set and get in and from sessionStorage
Storage.set(StorageKeys.KEY1, json);
let stored = <Object>Storage.get(StorageKeys.KEY1);

console.log(stored.value1 + ' ' + stored.value2); // print Hello World in the console

// set and get in and from localStorage
Storage.set(StorageKeys.KEY2, json, true);
stored = <Object>Storage.get(StorageKeys.KEY2, true);

console.log(stored.value1 + ' ' + stored.value2); // print Hello World in the console

// example for remove a key from storages

// remove a key from sessionStorage
Storage.remove(StorageKeys.KEY1);

console.log(Storage.get(StorageKeys.KEY1) == null); // print true

// remove a key from localStorage
Storage.remove(StorageKeys.KEY2, true);

console.log(Storage.get(StorageKeys.KEY2) == null); // print true

// clean all storages in sessionStorage
Storage.clear();

console.log(Storage.get(StorageKeys.sessionKey) == null); // print true
console.log(Storage.get(StorageKeys.localKey) == null); // print false because you cleaned sessionKey not localStorage

// clear all storages in localStorage
Storage.clear(true);

console.log(Storage.get(StorageKeys.localKey) == null); // print true

// you also can clean all storages with single method:
// Storage.clearAll();
