Workers communication strategy

[TCMiranda]

Hello guys,

I am using Pigato in some projects for now, but sometimes I still get confusing about allowing workers to communicate or even to use each others services.

In some scenarios, I prefer to not allow sub levels of workers, but in other scenarios, this gives me much duplicate code, which I solve creating shared modules.

To illustrate a little better:

So, what are your thoughts about it?
Does anyone knows some good reference on this subject?

@TCMiranda in my opinion the right solution is the first.
Workers can communicate between them via a Pigato client as well, so no need of direct interaction.

Sometimes you may want to reuse code between multiple workers.
There you have two solutions:

1. use a shared library via a separate github/npm project: suggested when you want to share simple solutions
2. create dedicated workers: suggested for the rest of usecases.

@prdn thanks for your answer!

So, if workers are connected to the "handlers broker" as clients, you would agree to allow them to "communicate" by messages without a separate layer like the second case?

Like this:

The second solution you mentioned would be that case when a worker posts another message as a client to finish its request, right?
