@minsulaiman/image-watcher v1.0.1

Image Watcher

Track image loading with Alpine.js like a hunter!

Description

This package creates an Alpine.js directive, which one could use to do stuff when images are loaded.

We start off by defining an alpine.js object variable with isLoaded property set to false. Then apply the x-image-watcher custom directive to the <img> element directly or to a parent element that contains an <img> element within...

And when the image is loaded, the imageWatcher associated with it - as an example of our object variable - would have its isLoaded property set to true.

An example code for the TALL Stack would be something like this:

<div
    x-data="{ imageWatcher: { isLoaded: false } }"
    x-image-watcher="imageWatcher"
>
    <img
        src="{{ asset('images/cool-image.png') }}"
        alt="cool image"
    >

    <span
        x-cloak
        x-show="imageWatcher.isLoaded"
        x-transition
    >
        The image is loaded! No way!
    </span>

    <!-- A timed example too! -->
    <span
        x-data="{ show: false }"
        x-effect="
            if (imageWatcher.isLoaded) {
                setTimeout(() => show = true, 1000);
            }
        "
        x-cloak
        x-show="show"
        x-transition
    >
        Wait a second...!
    </span>
</div>

Installation

Again, since this is an Alpine.js directive, we need that awesomeness installed first!

Requirements

• Alpine.js

Steps

1. Install the package via NPM:

   Alpine.plugin(imageWatcher);
   
   Alpine.start();
   ...
