Installation

npm i storage-function

Breaking Change

Before 2.0.0 version each function should be import itself like below

import { toLocalStorage, toSessionStorage } from 'storage-function';

or import them with an alias like below

 import * as storageFunction from 'storage-function';

With 2.0.0 version its enough to just import storageFunction then you can reach all helpful function under it like below.

import { storageFunction } from 'storage-function';

Usage

Local storage key and value definitions

Sample key and value definition for testing local storage functions.

const localStorageKey = 'local_storage_key';

const localStorageValue = {
  name: 'object value',
  stringValue: 'string value',
  booleanValue: true,
  numberValue: 1234567890,
  dateValue: new Date(),
};

toLocalStorage

import { storageFunction } from 'storage-function';

storageFunction.toLocalStorage(localStorageKey, localStorageValue);

fromLocalStorage

import { storageFunction } from 'storage-function';

console.log(storageFunction.fromLocalStorage(localStorageKey));

Result:
{"name":"object value","stringValue":"string value","booleanValue":true,"numberValue":1234567890,"dateValue":"2021-08-22T15:57:05.147Z"}

removeFromLocalStorage

import { storageFunction } from 'storage-function';

storageFunction.removeFromLocalStorage(localStorageKey);

clearLocalStorage

import { storageFunction } from 'storage-function';

storageFunction.clearLocalStorage(); // Remove all local storage keys

const exceptedKeys = ['some_key', 'another_key'];
storageFunction.clearLocalStorage(exceptedKeys); // Remove all local storage keys except exceptedKeys

getKeysFromLocalStorage

import { storageFunction } from 'storage-function';

console.log(storageFunction.getKeysFromLocalStorage());

Result:
(2) ["localKey2", "localKey1"]
0: "localKey2"
1: "localKey1"

getAllFromLocalStorage

import { storageFunction } from 'storage-function';

console.log(storageFunction.getAllFromLocalStorage());

Result:
(2) [{…}, {…}]
0: {localKey2: "\"Local storage value 2\""}
1: {localKey1: "\"Local storage value 1\""}

getKeysCountFromLocalStorage

import { storageFunction } from 'storage-function';

storageFunction.toLocalStorage(localStorageKey, localStorageValue);

console.log(storageFunction.getKeysCountFromLocalStorage());

Result:
1

Session storage key and value definitions

Sample key and value definition for testing session storage functions.

const sessionStorageKey = 'session_storage_key';

const sessionStorageValue = {
  name: 'object value',
  stringValue: 'string value',
  booleanValue: true,
  numberValue: 1234567890,
  dateValue: new Date(),
};

toSessionStorage

import { storageFunction } from 'storage-function';

storageFunction.toSessionStorage(sessionStorageKey, sessionStorageValue);

fromSessionStorage

import { storageFunction } from 'storage-function';

console.log(storageFunction.fromSessionStorage(sessionStorageKey));

Result:
{"name":"object value","stringValue":"string value","booleanValue":true,"numberValue":1234567890,"dateValue":"2021-08-22T15:58:28.646Z"}

removeFromSessionStorage

import { storageFunction } from 'storage-function';

storageFunction.removeFromSessionStorage(sessionStorageKey);

clearSessionStorage

import { storageFunction } from 'storage-function';

storageFunction.clearSessionStorage(); // Remove all session storage keys

const exceptedKeys = ['key_one', 'keyTwo'];
storageFunction.clearSessionStorage(exceptedKeys); // Remove all session storage keys except exceptedKeys

getKeysFromSessionStorage

import { storageFunction } from 'storage-function';

console.log(storageFunction.getKeysFromSessionStorage());

Result:
(2) ["sessionKey2", "sessionKey1"]
0: "sessionKey2"
1: "sessionKey1"

getAllFromSessionStorage

import { storageFunction } from 'storage-function';

console.log(storageFunction.getAllFromSessionStorage());

Result:
(2) [{…}, {…}]
0: {sessionKey2: "\"Session storage value 2\""}
1: {sessionKey1: "\"Session storage value 1\""}

getKeysCountFromSessionStorage

import { storageFunction } from 'storage-function';

storageFunction.toSessionStorage(sessionStorageKey, sessionStorageValue);

console.log(storageFunction.getKeysCountFromSessionStorage());

Result:
1

Storage functions definition

They work with local and session storage.

clearStorage

import { storageFunction } from 'storage-function';

storageFunction.clearStorage(); // Remove all storage keys

const exceptedKeys = ['id_token', 'access_token'];
storageFunction.clearStorage(exceptedKeys); // Remove all storage keys except exceptedKeys

getKeys

import { storageFunction } from 'storage-function';

console.log(storageFunction.getKeys());

Result:
{localStorage: Array(2), sessionStorage: Array(2)}
localStorage: (2) ["localKey2", "localKey1"]
sessionStorage: (2) ["sessionKey2", "sessionKey1"]

getAll

import { storageFunction } from 'storage-function';

console.log(storageFunction.getAll());

Result:
{localStorage: Array(2), sessionStorage: Array(2)}
localStorage: Array(2)
0: {localKey2: "\"Local storage value 2\""}
1: {localKey1: "\"Local storage value 1\""}
sessionStorage: Array(2)
0: {sessionKey2: "\"Session storage value 2\""}
1: {sessionKey1: "\"Session storage value 1\""}

getKeysCount

import { storageFunction } from 'storage-function';

storageFunction.toLocalStorage(localStorageKey, localStorageValue);
storageFunction.toSessionStorage(sessionStorageKey, sessionStorageValue);

console.log(storageFunction.getKeysCount());

Result:
{localStorage: 1, sessionStorage: 1}
