[0.2.0] — 2026-02-25

Bug fixes

Container stops instantly now.
The server previously had no signal handlers. When docker stop (or any process manager) sent SIGTERM, Node ignored it, forcing Docker to wait out its full timeout before issuing SIGKILL. The fix adds SIGTERM and SIGINT handlers that close all open SSE connections first (which were the main blocker — they are long-lived keep-alive HTTP responses), then drain remaining connections via server.close(), with a 5-second forced-exit safety net.

New features

Full real-time dashboard sync

The dashboard previously only received new push notifications over SSE. Deletes and subscription changes required a page refresh or waited for the 10-second poll. The dashboard now stays fully in sync with the server for all state changes via six new SSE event types:

Event	When it fires
message:deleted	A single message is deleted
messages:cleared	All messages are deleted
subscription:created	A new subscription is created
subscription:deleted	A subscription is deleted
subscriptions:cleared	All subscriptions are deleted

The 10-second subscription polling interval has been removed.

Subscriptions tab

The dashboard now has a dedicated Subscriptions tab alongside the Messages tab. It shows all active subscriptions with their message count and creation time. Selecting a subscription shows its full details in the right panel — endpoint URL, p256dh key, auth secret, and the complete subscription JSON object ready to paste directly into a web-push sendNotification() call. A + New Subscription button creates one without leaving the dashboard.

Delete from the dashboard

• Every message row and subscription row now has a × delete button (appears on hover) that removes it immediately via the API. The SSE event updates the list in real time — no optimistic UI needed.
• The detail panel for both messages and subscriptions also includes a delete button.

SSE auto-reconnect

If the SSE connection drops (e.g. server restart), the dashboard detects the disconnect, shows a "Reconnecting…" status, and re-fetches all messages and subscriptions once the connection is restored so no state is lost.

Toast notifications

A non-blocking toast slides in at the top-right whenever a new push notification arrives, showing a preview of the message content. Toasts also appear for reconnect events and other actions.

Copy buttons

The message and subscription detail panels now have Copy buttons next to every field worth copying — message ID, subscription ID, endpoint URL, p256dh, auth, payload JSON, raw payload, and the full subscription JSON. Clicking shows a brief "Copied!" confirmation.

Relative timestamps

Message and subscription rows now show human-friendly relative times ("just now", "5m ago", "2h ago") instead of raw ISO strings. They refresh every 30 seconds automatically.

Internal changes

• Extracted SSE state and broadcast logic into a dedicated src/server/services/sse.ts module so both message-store.ts and subscription-manager.ts can broadcast events without circular dependencies.
• Added 6 new integration tests covering every SSE event type, using a fetch-streaming helper that correctly races SSE connection setup with the triggering action.
