Vue Localstore

Introduction

Vue Localstore is a powerful library for managing local storage in Vue.js applications. It provides a convenient way to store and retrieve data locally in the browser, allowing developers to persist data across page refreshes or even between different sessions.

With Vue Localstore, you can easily store and access complex data structures in local storage, providing seamless data persistence for your Vue applications. It simplifies the process of using local storage and handles the complexities involved in dealing with data serialization and deserialization.

Features
1. Store and Retrieve Data

Vue Localstore allows you to store data in the browser's local storage using a simple and intuitive API. You can easily save data objects, arrays, or any other supported JavaScript data types.

// Store data
Vue.localstore.set('key', data);

// Retrieve data
const storedData = Vue.localstore.get('key');
2. Automatic Serialization and Deserialization

Vue Localstore automatically handles the serialization and deserialization of complex data structures when storing and retrieving data. You can store and retrieve objects, arrays, numbers, strings, booleans, and more without worrying about the underlying data format.

const user = { name: 'John Doe', age: 30 };

// Store complex data
Vue.localstore.set('user', user);

// Retrieve complex data
const storedUser = Vue.localstore.get('user');
console.log(storedUser.name); // Output: John Doe
3. Data Expiration

Vue Localstore provides options for setting an expiration time for stored data. You can specify a time-to-live (TTL) value in milliseconds, after which the data will be automatically removed from local storage.

// Store data with expiration time
Vue.localstore.set('key', data, { ttl: 60000 }); // Expires after 1 minute (60,000 milliseconds)

// Retrieve data, returns null if expired
const storedData = Vue.localstore.get('key');
4. Event Emitters

Vue Localstore offers event emitters to notify your Vue components when data stored in local storage changes. You can subscribe to these events to keep your application's state in sync with the stored data.

import Vue from 'vue';

// Listen for data change events
Vue.localstore.on('dataChange', (key, newValue, oldValue) => {
  console.log(`Data with key ${key} changed from ${oldValue} to ${newValue}`);
});

// Stop listening for data change events
Vue.localstore.off('dataChange');
Usage
  1. Install Vue Localstore using npm or yarn:
npm install vue-localstore
  1. Import and register the library in your Vue application:
import Vue from 'vue';
import VueLocalstore from 'vue-localstore';

Vue.use(VueLocalstore);
  1. Start using local storage in your Vue components:
export default {
  data() {
    return {
      user: {}
    };
  },
  mounted() {
    // Store user data
    this.$localstore.set('user', { name: 'John Doe', age: 30 });

    // Retrieve user data
    this.user = this.$localstore.get('user');
  }
}
Conclusion

Vue Localstore simplifies the process of using local storage in Vue.js applications. It provides an easy-to-use API for storing and retrieving data, handles serialization and deserialization seamlessly, supports data expiration, and offers event emitters for data change notifications. This library is a valuable tool for managing local data and ensuring a smooth user experience.
