`ActionCable.server.config.pubsub_adapter` always constantize?

[ioquatix]

I wonder if we can make this easier to configure?

I wanted to use something other than an adapter under ActionCable::SubscriptionAdapter::.

actioncable-next/lib/action_cable/server/configuration.rb

Line 44 in f9c1c22

return @pubsub_adapter.constantize if @pubsub_adapter

I don't have much idea about what could be better.

Maybe we need to introduce a server configuration class that can be overridden, e.g. to set reasonable defaults or change default behaviour. For example, the executor, and the pubsub adapter instance, etc.

I added this line exactly to quick-solve this problem. You can use any class name is the value now. But having something like the following would be great, too:

# Pass any object
config.action_cable.pubsub_adapter = MyAdapter.new

# Pass a class name
config.action_cable.pubsub_adapter = "MyAdapter"

# Pass an identifier with options (current official behaviour)
config.action_cable.pubsub_adapter = :redis, url: "redis://localhost:50051"

Actually, I don't really understand why do we have cable.yml at all 🤷‍♂️
