PubSub consumer never consumes messages with RabbitSubscribe

Hello,

I have an issue with consuming messages in a pubsub maner. I am able to create a connection to the exchange and to publish messages on it (confirmed on the UI).

I do not understand why my function associated with RabbitSubscribe is never called. I have triple checked the exchange and route key and it is correct.

In my Module I use :

		RabbitMQModule.forRoot(RabbitMQModule, {
			exchanges: [
			  {
				name: 'exchange1',
				type: 'fanout',
			  },
			],
			uri: 'amqp://localhost:5672',
			connectionInitOptions: { wait: false },
		  }),

And my service :

import { Injectable } from "@nestjs/common"
import { AmqpConnection, RabbitSubscribe } from "@golevelup/nestjs-rabbitmq"

@Injectable()
export class MailService {
	constructor(private readonly amqpConnection: AmqpConnection) {
		// setTimeout(function() {
		// 	console.log("inside")

		// 	amqpConnection.publish("exchange1", "subscribe-route", { msg: "hello world" })
		// }, 3000)
	}

	@RabbitSubscribe({
		exchange: "exchange1",
		routingKey: "subscribe-route",
		queue: "subscribe-queue",
	})
	public async pubSubHandler(msg: {}) {
		console.log(`Received message: ${JSON.stringify(msg)}`)
	}
}

Is there something I am missing ? Thanks

No problem. I’m going to close this now as the root cause has been identified and will track any additional info in the dedicated issue for microservices support

@LucSalommez Unfortunately the library isn’t a “true” NestJS microservice at the moment so we can’t rely on startAllMicroservicesAsync to establish listeners at the moment. I’ll need to look into this a bit more and see what solutions make sense

Tracking this with #274
