is NATS supported currently?

var serviceBrokerConfig = &moleculer.Config{
	LogLevel: "info",
	Transporter: "nats://dev.nats.svc:4222",
}

Above configuration is ignored and just created MEMORY transporter, should i wait for the feature?

commented

I think so.

Keep an eye on the documentation, we're working to keep that up-to-date as well:

@dehypnosis NATS streaming is the first transporter implemented, but it is not reading the URL from the config yet :( .. a very small thing to fix.. I'll get it done today, is in my list for some time.

Currently, my team made a bunch of moleculer services based on moleculer-js with NATS transporter. And beyond node.js, we needed moleculer library based on fast compiled language like golang.

So after your release, I gladly made a PoC service with moleculer-go to try to connect existing services based on moleculer-js. For this yesterday I made a NATS transporter (not STAN) and a simple moleculer-go service. So messaging itself between moleculer-go and moleculer-js works well.

But current moleculer-go seems that has not exactly same protocol with moelculer-js. For example, moelculer-go discovers remote actions as []interfaces{} type assertion, but moleculer-js services reply as map[string]interfaces{}. And there some miscellaneous issues make runtime error while discovering, and call each others between different moleculer client library.

Anyway i'm on this issue, and almost modified code to discover and call each other well. But while i was working on it, I thought that it is not sure that does moleculer-go want to integrated with 'moelculer-js'.

So, here is a question, the differences between moleculer-go and moleculer-js about service discovery payload and actions catalog structure are intended design by moleculer-go author?

@dehypnosis this is awesome! One of the use cases that we believe people have and that this tool can be useful.

The goal is to be 100% compatible with Moleculer JS.

The reason you found this bug :( .. is because I have not done much testing integrating both (go and JS) yet, but this is in our roadmap. Looks like you started on it :) I'm happy to help u to get this over and quick.

Can you please share your NATS transporter?

Do you have a test with your transporter that I can use to see these error and do the fixes? I'm also happy to review and contribute to your PR to get this fixed.

@dehypnosis and @slaterx I create a new issue to fix the hardcoded problem -> #54

And this one related to Moleculer JS incompatibility. -> #55

I'm closing this one now.
