      if (!options) {
        return this.createIOServer(port);
      }
      const { namespace, server, ...opt } = options;
      return server &amp;&amp; isFunction(server.of)
        ? server.of(namespace)
        : namespace
          ? this.createIOServer(port, opt).of(namespace)
          : this.createIOServer(port, opt);
    }
