Class ProtocolDecoder

Decodes incoming WebSocket frames and dispatches them to type-specific handlers.

const decoder = new ProtocolDecoder();
decoder.on(BridgeMessageType.RENDER_COMMAND, (msg) => primitiveRenderer.apply(msg.command));
decoder.on(BridgeMessageType.SESSION_START, (msg) => deviceState.setActiveSession(/* … */));
websocket.onmessage = (e) => decoder.decode(e.data);
