Usage

After installing the package, you can import the NgStorageService into your Angular components or services to store, retrieve, and remove data from session storage.

Importing the Service

To begin, import the service into your Angular component or service:

import { NgStorageService } from  'ng7-storage';

Storing Data

export  class  ExampleComponent {

constructor(private  storageService:  NgStorageService) {}

storeData() {

// Store with optional encryption

this.storageService.setData("user", { name: "John Doe", age: 30 }, true);

}

}

Retrieving Data

export  class  ExampleComponent {

constructor(private  storageService:  NgStorageService) {}

getData() {

// Retrieve with optional decryption

const  userData  =  this.storageService.getData("user", true);

console.log("Retrieved data:", userData);

}

}

Removing Data

export  class  ExampleComponent {

constructor(private  storageService:  NgStorageService) {}

clearData() {
// Remove specific data
this.storageService.removeData('user');
