 Alpine persist plugin allows you to store data across page loads. This plugin is very useful when you want to store currently active tabs, filters, sorting order and etc.

Install Alpine.js Persist Plugin
You can either use the CDN or install via NPM.
<script defer src="https://unpkg.com/@alpinejs/[email protected]/dist/cdn.min.js"></script>

Using NPM / Yarn.
npm install @alpinejs/persist

yarn add @alpinejs/persist

Initialize the Plugin
From your Javascript main file, you need to include the plugin before the alpine js initialization.
// js/app.js

import Alpine from 'alpinejs'
import persist from '@alpinejs/persist'

Alpine.plugin(persist)

Alpine.start()

Use the Persist Plugin
To use the persist plugin you just have to define the data value wrapped with "$persist(x)" method.

By doing so when the user presses the increment button, the number of counts increases and it will be persisted on the browser local storage.
<div x-data="{ count: $persist(0) }">
    <button x-on:click="count++">Increment</button>

    <span x-text="count"></span>
</div>
