Configuring JavaScript plugins

You can configure your plugins from inside the templates via data-options. Define a static options object inside your plugin and assign your options with default values to it. In your case define a text option and as a default value use the text you previously directly prompted to the user. And instead of the hard coded string inside the alert() use your new option value.

// src/Resources/app/storefront/src/main.js

import Plugin from 'src/plugin-system/plugin.class';

export default class ExamplePlugin extends Plugin {
    static options = {
         * Specifies the text that is prompted to the user
         * @type string
        text: 'seems like there\'s nothing more to see here.',

    init() {
        const that = this;
        window.onscroll = function() {
            if ((window.innerHeight + window.pageYOffset) >= document.body.offsetHeight) {

Now you are able to override the text that is prompted to the user from inside your templates. Therefore create an product-detail folder inside your Resources/views/storefront/page folder and add an index.html.twig file inside that folder. In your template extend from @Storefront/storefront/page/product-detail/index.html.twig and override the page_product_detail_content. After the parent content add an template tag with the data-example-plugin tag also to activate your plugin on product detail pages. Next add an data-{your-plugin-name-in-kebab-case}-options (data-example-plugin-options) attribute to the DOM element you registered your plugin on (the template tag). As the value of this attribute use the options you want to override as a json object.

{% sw_extends '@Storefront/storefront/page/product-detail/index.html.twig' %}

{% set examplePluginOptions = {
    text: "Are you not interested in this product?"
} %}

{% block page_product_detail_content %}
    {{ parent() }}

    <template data-example-plugin data-example-plugin-options='{{ examplePluginOptions|json_encode }}'></template>
{% endblock %}

It is best practice to use a variable for the options because this is extendable from plugins.
