NestJS multiple WebSocketGateway

Question

Is it possible to run one NestJS WebSocketGateway several times with different parameters? Maybe possible to use microservices for this?

Answer 1

Yes, it is possible to create as much WebSocketGateway as you want. All you need is to register your gateways in providers property of your @Module. Gateways with same port will use only 1 socket.io server instance. When you create gateway with another port, NestJS will create one more server instance and so on.
