Auto DLQ

This is a package I built while working on one of my article. I was trying things around and explore rabbitMQ. It depends on streadway/amqp.

autodlq.DeclareQ

It helps to declare a queue with its DLX in case you passed a config implementation with SupportDlq() bool that returns true.

autodlq.ConsumeQ

It helps decouple your infrastructure code from application. You are not supposed to worry about infrastructure things. You just need to have Consumer implementation with the desired behaviour you need on:

OnConsuming(d amqp.Delivery) error What functions should be invoked while handling your message.
OnConsumed(d amqp.Delivery) error What should happen after successfully consuming the message. Maybe some useful logs.
OnRetry(d amqp.Delivery) error How to retry the message.
OnMaxRetry(d amqp.Delivery) error What should happen when we reached the max retry.
