VrmEventSource.close

import { Vrm } from "@hmcs/sdk";

eventSource.close() closes the SSE connection and stops receiving events.

const eventSource = character.events();
// ... register listeners ...

// When done:
eventSource.close();

VrmEventSource also implements Disposable, so you can use TypeScript's using declaration for automatic cleanup:

{
  using eventSource = character.events();
  eventSource.on("state-change", (e) => {
    console.log("State:", e.state);
  });
  // eventSource.close() is called automatically here
}
