Nestjs rabbitmq publisher, consumer and hhtp API in one application - rabbitmq

Question

I need to know if it's possible to have all these three in single application. I have seen many examples where there are two different project one for RabbitMQ publisher and one for subscriber/consumer.
I just need to know if there's a possibility to implement something like that. I failed to find any example consisting both in one app.
I have tried to implement something similar but it did not work.
