What are the patterns or ways to do notifications in Rails?

Question

Ruby on Rails

There was a need to make notifications and notifications of different types in different directions. I could hang everything in after_create, but I think this is the way of the loser. Tell me where to read or what keywords to search for best practices on the topic? I understand that you need some kind of ActiveMQ-type queue service or some services, I don’t know. Maybe someone came across and will give a recommendation? On mind it would be desirable, but without fanaticism.

Answer 1

Read about ActiveJob in the Rails guide. From simple backends to ActiveJob, I repeatedly use DelayedJob, which does not require the installation of additional DBMS to store queue data.
You can "hang in after_create" adding a task to the queue. This task will be asynchronously processed by another process and the client will not have to wait for it to wait.
I would like to clarify: notifications should occur within the application, between objects? Or over the network?
If the former, then try

If the latter, then using message queue technologies (ZMQ, AMQP), Redis pub/sub, WebSocket and corresponding gems.
