Fern
Persisted global stores for Alpine 3.x.
Installation
Since Fern directly extends the global Alpine object, the recommended installation methods are NPM or a module <script> tag.
NPM
Install Fern by running the following command:
npm install @ryangjchandler/fern
Inside of your main script, add the following code:
import Alpine from 'alpinejs'
import Fern from '@ryangjchandler/fern'
Alpine.plugin(Fern)
Alpine.start()
<script type="module">
Add the following <script> to the <head> of your document before including Alpine:
<script type="module">
import Fern from 'https://cdn.jsdelivr.net/npm/@ryangjchandler/[email protected]/dist/module.esm.js'
document.addEventListener('alpine:initializing', () => {
window.Alpine.plugin(Fern)
})
</script>
Usage
Fern adds a new persistedStore method to the global Alpine object. The method's definition and usage is identical to Alpine.store():
Alpine.plugin(Fern)
Alpine.persistedStore('counter', 0)
Alpine.start()
Creating a persistedStore will register a normal store with Alpine and keep track of all changes, pushing them back to localStorage when updated.
<div x-data>
<p x-text="$store.counter"></p>
<button x-on:click="$store.counter++">Increment</button>
</div>
If you're using the <script type="module"> installation method, be sure to make your persistedStore calls after registering Fern.
document.addEventListener('alpine:initializing', () => {
window.Alpine.plugin(Fern)
window.Alpine.persistedStore('counter', 0)
})
