Add focal point alignment of images to your Alpine 3.x components with a custom directive.
This package only supports Alpine v3.x.
This plugin adds a new x-focal directive to Alpine that allows to easliy align your images to keep focus on the selected part of the image.
Include the following <script> tag in the <head> of your document, just before Alpine.
<script
src="https://cdn.jsdelivr.net/npm/@lefrancois/alpine-focal@1/dist/cdn.min.js"
defer
></script>npm install @lefrancois/alpine-focalAdd the x-focal directive to your project by registering the plugin with Alpine.
import Alpine from "alpinejs";
import Focal from "@lefrancois/alpine-focal";
Alpine.plugin(Focal);
window.Alpine = Alpine;
window.Alpine.start();Attach the x-focal directive on an image element and enter the point (unsing px or % informations) to keep in focus while containing the image.
<div x-data>
<img
src="..."
width="400px"
height="600px"
x-focal="10% 80%"
>
</img>
</div>Optinally you can use set the third parameter to true (x-focal="100px 100px true") to get a preview image where you can set the focal point with an easy click on the image. Note: Just copy and paste the value to the x-focal attribute of the image element in production. ;) This is just a helper for your development.
