+title: Catch Up on Notifications
+description: "Learn how to show Puter notifications in your app with Puter.js events, including the ones that arrived while your app was closed."
+tags: [events]
+order: 66
+---
+
+<div class="info">The Events API is in beta. Event shapes, limits, and behavior may change between releases.</div>
+
+Puter posts notifications to a user's account when something needs their
+attention, for example when a persistent subscription your app made for them
+ends, or, for the app's owner, when its worker finishes deploying. With the
+[Events API](/Events/) your app can show these as they arrive, and catch up on
+the ones that came in while it was closed. Puter creates notifications itself.
+An app can't post its own.
+
+This recipe builds on [Watch for Changes](/recipes/events-watch-for-changes/),
+which covers what every subscription shares: gaps, stopping, reconnects and
+cost. The examples call `showNotification(event)`, your own function that shows
+one notification, such as a toast or a row in a panel.
+
+## Show New Notifications
+
+To show notifications as they arrive, subscribe to `notif:app-user` with
+[`puter.events.onLocal()`](/Events/onLocal/):
+
+```js
+const sub = await puter.events.onLocal('notif:app-user', ({ event }) => {
+    if (event.op === 'gap') return;
+    showNotification(event);
+});
+```
+
+A gap carries no notification, so this handler skips it.
+[Catch Up, Then Keep Listening](#catch-up-then-keep-listening) handles gaps
+properly. The fields to use are:
+
+- `id`: the notification's id. A notification has the same `id` whether it
+  arrives live or from `fetch()`, so use it to tell notifications apart.
+- `type`: what kind of notification it is, such as `app.events.ended`.
+- `notification.title`: the text to show. The other fields in `notification`
+  depend on the type.
+- `ts`: when it was created, in milliseconds since the epoch.
+
+Don't use `seq` or `ts` to tell notifications apart. `seq` is only a position
+within one page or one delivery, and two notifications can share a `ts`.
+
+## Which Notifications Your App Sees
+
+A `notif:` subject names one part of the user's notifications:
+
+- `notif:app-user` is about the user's use of your app. Today that is Puter
+  telling them that a [persistent subscription](/Events/onPersistent/) your app
+  made for them has ended or stopped delivering (`app.events.ended`).
+- `notif:developer` is about your app itself, for the account that owns it:
+  your app's worker deploys (`app.worker.deployed`, `app.worker.deployFailed`)
+  and suspended event handlers (`app.events.suspended`). For any other user,
+  `onLocal()` rejects with `subject_does_not_exist` and `fetch()` returns an
+  empty page.
+- `notif:account` holds account notifications, such as a file shared with the
+  user. Apps and websites never see these, and no permission changes that.
+  `onLocal()` rejects with `subject_does_not_exist` and `fetch()` returns an
+  empty page.
+
+Reading your app's own notifications needs no permission. Puter fills in your
+[app ID](/Utils/appID/), so the subject never needs one, and another app's
+notifications are never visible to yours.
+
+## Read What You Missed
+
+To read the notifications that arrived while your app was closed, call
+[`puter.events.fetch()`](/Events/fetch/). It returns a page of notifications,
+oldest first, in the same shape as live ones. Pass each page's `cursor` back as
+`after` until a page comes back without one:
+
+```js
+let after;
+do {
+    const page = await puter.events.fetch({ subject: 'notif:app-user', after });
+    page.items.forEach(showNotification);
+    after = page.cursor;
+} while (after);
+```
+
+A page holds 50 notifications by default. Pass `limit` for up to 200, and a
+larger `limit` is treated as 200. Without `after`, `fetch()` starts from the
+oldest notification Puter still keeps. Puter deletes old notifications after a
+while, so a user who was away longer than that starts from what is left.
+
+`fetch()` only reads. It doesn't mark anything as read, and it also returns
+notifications the user already dismissed, so your app has to remember what it
+has shown. The next section does that.
+
+Only `notif:` subjects can be fetched. A `kv:` or `fs:` subject rejects with
+`fetch_unsupported_subject`, because nothing stores those changes. Read the
+data itself again instead, as in
+[Watch for Changes](/recipes/events-watch-for-changes/).
+
+## Catch Up, Then Keep Listening
+
+To show each notification once, across visits, combine the two. Subscribe, then
+fetch from where the last visit stopped, and save the cursor with
+[`puter.kv`](/KV/) so the next visit starts there:
+
+```js
+const subject = 'notif:app-user';
+const saved = await puter.kv.get('notifications') ?? {};
+let after = saved.after;
+const seen = new Set(saved.seen);
+
+function showOnce (event) {
+    if (seen.has(event.id)) return;
+    seen.add(event.id);
+    showNotification(event);
+}
+
+async function save () {
+    await puter.kv.set('notifications', { after, seen: [...seen].slice(-200) });
+}
+
+async function catchUp () {
+    let page;
+    do {
+        page = await puter.events.fetch({ subject, after });
+        page.items.forEach(showOnce);
+        after = page.cursor ?? after;
+    } while (page.cursor);
+    await save();
+}
+
+await puter.events.onLocal(subject, async ({ event }) => {
+    if (event.op === 'gap') return catchUp();
+    showOnce(event);
+    await save();
+});
+await catchUp();
+```
+
+Subscribe first, then fetch. A notification created while `catchUp()` runs then
+reaches the handler. If you fetch first, one created between the fetch and the
+subscription stays hidden until the next visit. Subscribing first means a
+notification can arrive both live and from `fetch()`, and `showOnce()` drops the
+second copy by `id`.
+
+The last page has no cursor, so `after` stays on the cursor before it, and the
+next visit reads that page again. That is why the ids are saved along with the
+cursor. Only the newest ones can come back, so the last 200 are enough.
+
+A [gap](/recipes/events-watch-for-changes/#handle-gaps) means notifications
+were not delivered, and one also arrives after a reconnect. Calling
+`catchUp()` on a gap reads what was missed, and `showOnce()` skips the rest.
+
+On a first visit there is no saved cursor, so `catchUp()` shows every
+notification Puter still keeps.
+
+## Notes
+
+- `fetch()` doesn't open the sign-in. On a website with nobody signed in, it
+  rejects with `token_missing`. In the example above, `puter.kv.get()` signs
+  the user in first. [Watch for Changes](/recipes/events-watch-for-changes/#watch-a-key)
+  shows how to start from a sign-in button.
+- Leave `after` undefined when there is no cursor. `fetch()` rejects `null`
+  with `invalid_request`.
+- `fetch()` allows 120 calls a minute per user and app, and rejects with
+  `too_many_requests` past that. Call it on start and on a gap, never on a
+  timer. The subscription already tells you when something new arrives. See
+  [Rate Limits and Quotas](/rate-limits-and-quotas/#events).
+- `fetch()` rejects with `invalid_subject_audience` for an audience other than
+  `app-user`, `developer` or `account`, and with `events_disabled` on a server
+  where events are off. A server with notification events turned off rejects
+  the `onLocal()` subscription with `invalid_subject`, while `fetch()` still
+  works.
+- A notification subscription counts toward the same subscribe limit and costs
+  the same per delivery as any other. [Watch for Changes](/recipes/events-watch-for-changes/#stop-watching)
+  covers `off()`, and its [Notes](/recipes/events-watch-for-changes/#notes)
+  cover cost.
