Vrm.streamMetadata

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

Vrm.streamMetadata(callback) opens a Server-Sent Events stream and fires the callback with VrmMetadata for every VRM that currently exists and for any VRM created in the future. Returns an EventSource that you can close when done.

const es = Vrm.streamMetadata((metadata) => {
  console.log(`VRM appeared: ${metadata.name} (entity: ${metadata.entity})`);
});

// Later, stop streaming
es.close();

Unlike Vrm.stream, this callback receives raw VrmMetadata (name and entity ID) instead of Vrm wrapper instances. Use it when you need lower-level control or want to construct Vrm instances yourself.
