-Another available adapter is a `WsAdapter` which in turn acts like a proxy between the framework and integrate blazing fast and thoroughly tested [ws](https://github.com/websockets/ws) library. This adapter is fully compatible with native browser WebSockets and is far faster than socket.io package. Unluckily, it has significantly fewer functionalities available out-of-the-box. In some cases, you may just don't necessarily need them though.

 > info **Hint** `ws` library does not support namespaces (communication channels popularised by `socket.io`). However, to somehow mimic this feature, you can mount multiple `ws` servers on different paths (example: `@WebSocketGateway({{ '{' }} path: '/users' {{ '}' }})`).
