Notifications

Push and in-app notifications use Worker-configured VAPID keys and the user-channel WebSocket.

Web push

import { useWebPush } from "@fluxy-chat/react";

import type { FluxyChatClient } from "@fluxy-chat/sdk";

function PushSettings({ client }: { client: FluxyChatClient }) {
  const { permission, requestPermissionAndSubscribe, unsubscribe } = useWebPush(client);

  if (permission === "unsupported") return null;

  return (
    <button onClick={() => requestPermissionAndSubscribe()}>
      {permission === "granted" ? "Push enabled" : "Enable push"}
    </button>
  );
}

Configure VAPID keys in Worker secrets / .dev.vars:

VAPID_PUBLIC_KEY=...
VAPID_PRIVATE_KEY=...

See Web push (VAPID).

User channel

useNotifications and useUserChannel subscribe to per-user realtime events (inbox refresh, mentions, system alerts):

import { useNotifications } from "@fluxy-chat/react";

useNotifications({ client, onEvent: (event) => console.log(event) });

Delivery types

Member JWT required for subscription registration.

Collab inbox kinds

useInbox items now include thread, comment, and custom besides mention/unread/follow_up/snooze. Map server_event comment fan-out with commentEventToInboxItem. UI: <InboxNotification /> from @fluxy-chat/ui. See Comments & threads.

Daily email digest (collab + chat)

Cron runDailyDigest (enable DAILY_DIGEST_ENABLED=true) emails yesterday's chat highlights and thread comments. Preferences:

GET  /digest/preferences
PATCH /digest/preferences  { enabled, email, emailEnabled, webPushEnabled, inAppEnabled }

SDK: client.getDigestPreferences() / client.updateDigestPreferences({ enabled: true, email }). Delivery: Cloudflare Email binding or RESEND_API_KEY. From: DIGEST_EMAIL_FROM / EMAIL_FROM. Comments-only days still send (no chat messages required).
