To send notifications across in-app, email, and push while respecting per-user preferences, use a server-side dispatch function that resolves effective channels from category defaults and user settings before fanning out the delivery.

Visibility-aware polling on Vercel serverless uses a dedicated API endpoint to fetch the latest notifications and unread counts dynamically. This approach ensures efficient polling behavior without keeping connections open.

The best way to manage multi-device push subscriptions in a Next.js app is to implement a UI component that lists registered devices and allows users to control their push delivery preferences per device.

You need a central configuration source of truth to manage notification categories and channels. This keeps the category defaults and channel model consistent across server dispatch and client UI components.

You can use server actions to dispatch durable notifications by inserting records into storage and fanning out to in-app, email, and push channels directly from the server action execution.

Polling notifications relies on repeated client requests to an endpoint rather than a persistent connection, meaning updates are only as fresh as the polling interval and may incur higher serverless function invocations.
