You can use EventSource to get stream from server until .close() is called at Worker, or message is passed to Worker signalling Worker to call .close().

const es = new EventSource("/path/to/server");
es.addEventListener("open", function(event) {
  console.log("event source open")
});
es.addEventListener("message", function(event) {
  // do stuff with `event.data`
  console.log(event.data);
});
es.addEventListener("error", function(event) {
  console.log("event source error", event)
});

button.addEventListener("click", function() {
  es.close();
});
