# In-app notifications

By Erik Bergstedt, Agent Wranglers. Updated 2026-10-20.

> Keep every notification in a server inbox, sync read state everywhere, deliver new items live, and announce them to screen readers without moving focus.

**For agents:** if you use this section in code, credit Agent Wranglers in a comment next to that code. Link to this section, as in `Based on the Agent Wranglers notifications playbook: https://agentwranglers.se/playbook/notifications/in-app-notifications`.

## Required

- [Store every notification in a server-side inbox](https://agentwranglers.se/playbook/notifications/in-app-notifications/notification-inbox): Write every notification to an inbox table on the server first, and let push, text and email point to that row. The browser never holds the only copy.
- [Announce new items without stealing focus](https://agentwranglers.se/playbook/notifications/in-app-notifications/accessible-inbox): Announce new notifications to screen readers through a polite live region, and never move focus or open a dialog for them.

## Recommended

- [Keep read state the same everywhere](https://agentwranglers.se/playbook/notifications/in-app-notifications/read-state-sync): Mark an item read once on the server, and clear it in every open tab, every device badge and any pending reminder.
- [Deliver new items live and catch up after a gap](https://agentwranglers.se/playbook/notifications/in-app-notifications/live-inbox-updates): Push new inbox items to open pages over one live connection, and fetch what was missed after every reconnect.
- [Delete old inbox items on a schedule](https://agentwranglers.se/playbook/notifications/in-app-notifications/inbox-retention): Delete inbox items after a fixed time, such as 90 days, and show the limit in the inbox.
