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 { Application, ServerSentEvent } from "https://deno.land/x/oak/mod.ts";

const app = new Application();

app.use((ctx) => {
  const target = ctx.sendEvents();
  const evt = new ServerSentEvent(
    "message",
    { hello: "world" },
    { id: 1 },
  );
  target.dispatchEvent(evt);
});
