@serve-tools/signal-shared-event-source

@serve-tools/signal-shared-event-source provides the shared EventSource client together with latest-event Signal state.

import { connect, observe } from "@serve-tools/signal-shared-event-source";

const client = connect<Events>(worker.port);
const presence = observe(client, "presence");

const state = presence.get();
if (state.status === "ready") console.log(state.event.lastEventId, state.event.data.online);

Install

npm install @serve-tools/signal-shared-event-source

Use @serve-tools/signal-shared-event-source/scope/shared-worker for listen() and the package root or /scope/window for connect() and observe(). The complete event record remains page-owned Signal state, including lastEventId. Use the underlying shared client subscription when every event occurrence matters.
