An event which contains information which will be sent to the remote connection and be made available in an EventSource as an event. A server creates new events and dispatches them on the target which will then be sent to a client.

Example

import {
  ServerSentEvent,
  ServerSentEventStreamTarget,
} from "https://deno.land/std@0.224.0/http/server_sent_event.ts";

Deno.serve({ port: 8000 }, (request) => {
  const target = new ServerSentEventStreamTarget();
  const evt = new ServerSentEvent("message", {
    data: { hello: "world" },
    id: 1
  });
  target.dispatchEvent(evt);
  return target.asResponse();
});
