localstorage-extra is a utility module that extends the functionality of the browser's localStorage. It provides methods for setting, getting, updating, and manipulating data in localStorage.

Installation

You can install localstorage-extra using npm or yarn.

Using npm:

npm install localstorage-extra

Using yarn:

yarn add localstorage-extra

Usage

First, import the AppStorage class from the module:

import AppStorage from 'localstorage-extra';

Basic Usage

Here's how you can use AppStorage to set`` and get`` values in localStorage:

// Set a value
AppStorage.set('user', { name: 'Alice', age: 30 });

// Get a value
const user = AppStorage.get('user');
console.log(user); // { name: 'Alice', age: 30 }

Update and Delete

You can update and delete values using the update and del methods:

// Update a value
AppStorage.update('user', 'age', 31);

// Delete a value
AppStorage.del('user', 'age');

Counting Values

You can count the number of values stored in localStorage:

const count = AppStorage.count('user'); // Number of values under 'user'
console.log(count); // 1

Filtering Data

You can filter and retrieve data using the getWhere method:

const adults = AppStorage.getWhere('user', (data) => data.age >= 18);
console.log(adults); // Array of users aged 18 and above

// or

const Alice = AppStorage.getWhere('user', { name: 'Alice' });

Counting Filtered Data

You can count filtered data using the countWhere method:

const adultCount = AppStorage.countWhere('user', (data) => data.age >= 18);
console.log(adultCount); // Number of users aged 18 and above

// or

const numberOfAlice = AppStorage.countWhere('user', { name: 'Alice' });
