PWA Push Notifications: AI-Generated Code Prompt Example

This prompt is designed for developers who want a self-contained, framework-free demonstration of Progressive Web App push notifications — one of the most effective tools for improving user retention. By requesting a complete implementation that covers service worker registration, VAPID key handling, subscribe/unsubscribe UI, and an offline fallback page, the prompt produces a fully functional reference project you can study, adapt, or present to clients. The glassmorphism card styling ensures the demo looks polished and modern right out of the box.

It works best with capable code-generation models such as GPT-4o or Claude 3.5 Sonnet. Real-world applications include bootstrapping a notification feature for a content site, e-commerce re-engagement flow, or SaaS onboarding reminder. To customize it, swap the hardcoded VAPID keys for your own server-generated pair, point the fetch call at your actual backend endpoint, and adjust the notification copy to match your brand. You can also extend the prompt by asking for a notification scheduling UI or multi-language permission dialogs.
