How can I get started with a JS field?

I want to create my own filament field (Slider) which is based on JS nouislider This is currently an Issue on github for filament 4.1. I want to get a jumpstart on this, and even if it doesnt get merged, at least I learned something new 😅 The problem is I have NO IDEA how to get started with javascript plugins. For starters, I added nouislider in the package.json. Furthermore, I've also create the Slider class, blade and JS file as follows: packages/forms/src/Components/Slider.php 
<?php

namespace Filament\Forms\Components;

use Filament\Support\Concerns\HasExtraAlpineAttributes;

class Slider extends Field
{
    use HasExtraAlpineAttributes;

    /**
     * @var view-string
     */
    protected string $view = 'filament-forms::components.slider';

    protected function setUp(): void
    {
        parent::setUp();
    }
}
<?php

namespace Filament\Forms\Components;

use Filament\Support\Concerns\HasExtraAlpineAttributes;

class Slider extends Field
{
    use HasExtraAlpineAttributes;

    /**
     * @var view-string
     */
    protected string $view = 'filament-forms::components.slider';

    protected function setUp(): void
    {
        parent::setUp();
    }
}
packages/forms/resources/js/components/slider.js 
export default function sliderFormComponent({ start = [20,80], min=0, max=100 }) {
    return {
        slider: null,

        init: function () {
            this.slider = document.getElementById('slider')

            noUiSlider.create(this.slider, {
                start: start,
                connect: true,
                range: {
                    'min': min,
                    'max': max
                }
            })
        }
    }
}
export default function sliderFormComponent({ start = [20,80], min=0, max=100 }) {
    return {
        slider: null,

        init: function () {
            this.slider = document.getElementById('slider')

            noUiSlider.create(this.slider, {
                start: start,
                connect: true,
                range: {
                    'min': min,
                    'max': max
                }
            })
        }
    }
}
packages/forms/resources/views/components/slider.blade.php 
<x-dynamic-component :component="$getFieldWrapperView()" :field="$field">
    <div
        id="slider"
        x-data="sliderFormComponent({ start: [20, 80], min: 0, max: 100 })"
        x-init="init()"
        ax-load-src="{{ \Filament\Support\Facades\FilamentAsset::getAlpineComponentSrc('slider', 'filament/forms') }}">
    </div>
</x-dynamic-component>
<x-dynamic-component :component="$getFieldWrapperView()" :field="$field">
    <div
        id="slider"
        x-data="sliderFormComponent({ start: [20, 80], min: 0, max: 100 })"
        x-init="init()"
        ax-load-src="{{ \Filament\Support\Facades\FilamentAsset::getAlpineComponentSrc('slider', 'filament/forms') }}">
    </div>
</x-dynamic-component>
In the create page, I have the Slider field, but when the page is loaded I get this error: Alpine component with ID [slider] not found for package [filament/forms]. What am I missing? Can anyone help?

Which is weird because Ive already added the nouislider in the devdependencies

It's not so weird, it can't find it... the url diesn't exist
Matthew
MatthewOP•5mo ago
any idea why that is? Have I missed some step? I also ran node bin/build.js to create the slider.js in /dist

toeknee•5mo ago
Looks like your slider.js hasn't been deployed to /forms/components/

You shouldn't be placing it there really as it's not part of the package why would it be put there? Have a look at how to include js in filament: https://filamentphp.com/docs/3.x/support/assets#registering-javascript-files

Ive already added it in the FormsServiceProvider
