browser-storage-helpers
is a utility package for managing cookies, localStorage
, and sessionStorage
with encryption and decryption support. It includes methods for securely storing, loading, and removing data using modern browser storage mechanisms.
Installation
To install the package, run the following command:
npm install browser-storage-helpers
Features
Securely store, load, and remove data in cookies, localStorage, and sessionStorage. Encrypt and decrypt stored data using XOR encryption. Built-in helpers for easy integration with browser storage mechanisms.
Usage
Importing the Helpers You can import the specific helpers as needed:
import { storeToLocalStorage, loadFromLocalStorage, clearFromLocalStorage } from 'browser-storage-helpers';
import { storeToSessionStorage, loadFromSessionStorage, removeFromSessionStorage } from 'browser-storage-helpers';
import { storeToCookie, loadFromCookie, clearFromCookie } from 'browser-storage-helpers';
LocalStorage Helper Methods
storeToLocalStorage - Stores encrypted data in localStorage.
storeToLocalStorage('user', { name: 'John Doe', email: '[email protected]' });
loadFromLocalStorage - Loads and decrypts data from localStorage.
const user = loadFromLocalStorage('user');
console.log(user); # { name: 'John Doe', email: '[email protected]' }
clearFromLocalStorage - Removes the specified item from localStorage.
clearFromLocalStorage('user');
SessionStorage Helper Methods
storeToSessionStorage - Stores encrypted data in sessionStorage.
storeToSessionStorage('sessionData', { sessionId: '12345' });
loadFromSessionStorage - Loads and decrypts data from sessionStorage.
const sessionData = loadFromSessionStorage('sessionData');
console.log(sessionData); # { sessionId: '12345' }
removeFromSessionStorage - Removes the specified item from sessionStorage.
removeFromSessionStorage('sessionData');
Cookie Helper Methods
storeToCookie - Stores encrypted data in a cookie. You can specify options like path and expiration.
storeToCookie('token', { authToken: 'abc123' }, { path: '/', maxAge: 3600 });
loadFromCookie - Loads and decrypts data from a cookie.
const tokenData = loadFromCookie('token');
console.log(tokenData); # { authToken: 'abc123' }
clearFromCookie - Removes the specified cookie.
clearFromCookie('token', { path: '/' });
Encryption and Decryption
The data stored using localStorage, sessionStorage, and cookies is automatically encrypted using XOR encryption. You can customize the encryption by modifying the encryption key in your .env or project environment variables.
By default, the encryption key is fetched from the environment variable ENCRYPTION_SECRET_KEY.
Environment Variables
The package uses the environment variable ENCRYPTION_SECRET_KEY for encrypting and decrypting data. You should define this variable in your .env file or environment configuration.
For example:
Vite.js (React, Vue) (.env):
VITE_APP_ENCRYPTION_SECRET_KEY=mySuperSecretKey123
React (CRA) (.env):
REACT_APP_ENCRYPTION_SECRET_KEY=mySuperSecretKey123
Vue.js (.env):
VUE_APP_ENCRYPTION_SECRET_KEY=mySuperSecretKey123
Angular (environment.ts):
export const environment = {
production: false,
ENCRYPTION_SECRET_KEY: 'mySuperSecretKey123'
};
