Why is the Subscription Widget not appearing when using the Web SDK via NPM?

When integrating the Pushwoosh Web SDK using the NPM package, the subscription widget (PWSubscribePopupWidget) is not initialized automatically by default. You must explicitly import and run the widget after the main SDK initialization.

Two details matter, and both are common sources of a silently missing widget:

• The package name is web-push-notifications.
• Widgets are shipped as subpath entry points. The root import exposes only Pushwoosh, so PWSubscribePopupWidget must be imported from web-push-notifications/widget-subscribe-popup.

Add the following after your init call:

import { Pushwoosh } from 'web-push-notifications';
import { PWSubscribePopupWidget } from 'web-push-notifications/widget-subscribe-popup';

const pushwoosh = new Pushwoosh();

// ... main SDK initialization code (pushwoosh.push(['init', { ... }])) ...

pushwoosh.push(async () => {
    try {
        const widget = new PWSubscribePopupWidget(pushwoosh);
        await widget.run();
    } catch (error) {
        console.error('PWSubscribePopupWidget initialization failed:', error);
    }
});

This ensures the custom subscription prompt is triggered correctly. If the import path is wrong the build either fails to resolve the module or PWSubscribePopupWidget arrives as undefined, and no widget is rendered.
