As I'm leaving medium to come here, this is my first article on dev.to. I hope you'll like it.

I decided to launch a resume builder with Sveltkit at CvLink.

After testing Flowbite, I had a clear preference for the look and feel and component offer of Preline.

But it was not easy to have the components react to click events. So I'm sharing what I did because I couldn't find any info on the web.

Steps

I'm presenting the steps briefly as I suppose that's what you're waiting for: getting it done and walk away :-)

install Preline

pnpm add preline

Add TailwindCss

to do the equivalent of npx in pnpm:
npx svelte-add@latest tailwindcss pnpm i

Install svelte-add globally, then use it to add tailwindcss
pnpm install -g svelte-add svelte-add tailwindcss

Configure tailwind

tailwind.config.js

const config = {
content: [
"./src/**/*.{html,js,svelte,ts}",
"./node_modules/preline/dist/*.js",
],

    theme: {
        extend: {},
    },

    plugins: [
        require('preline/plugin')
    ],
    darkMode: 'class',
};

module.exports = config;

Adapt Preline js files

Instead of having the js load at document.on('load') ex:

document.addEventListener('load', window.HSAccordion.init());

We make it load lazily when a component displays for its first time.

Files were copied from preline

I copied ./core/component.js to a local folder ./preline/component

And copied HSAccordion to ./accordion/Accordion.js next to its Svelte component

Skipping js-loading when in SSR

Accordion

When index.js was loaded, it attached components' js to window like follows:

window.HSAccordion = new HSAccordion();
document.addEventListener('load', window.HSAccordion.init());

I moved that init code to the AccordionItem component, checking i'm in the browser before initializing like follows:

<script>
    import Accordion from './Accordion';

    if(typeof window !== 'undefined') {
        console.log(  "initializing accordion" )
        window.HSAccordion = new Accordion();
        window.HSAccordion.init();
    }
    export let name;
</script>

The code for the accordion is pretty direct, then:
AccordionItem.svelte

<script>
    import Accordion from './Accordion';

    if(typeof window !== 'undefined') {
        console.log(  "initializing accordion" )
        window.HSAccordion = new Accordion();
        window.HSAccordion.init();
    }
    export let name;
</script>

<li class='hs-accordion' id='account-accordion'>
    <a
        class='hs-accordion-toggle flex items-center gap-x-3.5 py-2 px-2.5 hs-accordion-active:text-blue-600 hs-accordion-active:hover:bg-transparent text-sm text-slate-700 rounded-md hover:bg-gray-100 dark:bg-gray-800 dark:hover:bg-gray-900 dark:text-slate-400 dark:hover:text-slate-300 dark:hs-accordion-active:text-white'
        href='javascript:;'>
        <slot name='icon' />
        <slot name='name'>{name}</slot>

                        stroke-width='2' stroke-linecap='round'></path>
        </svg>
    </a>

    <div id='account-accordion-child'
             class='hs-accordion-content w-full overflow-hidden transition-[height] duration-300 hidden'>
        <slot name='content' />
    </div>
</li>

I created a repository where you can benefit of the work directly.

Known bugs: Sometimes the js is not loaded, happens in dev mode, I still didn't check if it happens in prod.
