How to create a connection between applications in golang in real time?

Question

go

Good afternoon,
There is a server and clients should be connected to it. You need to make a channel and notify the server / clients in real time.
How to make a websocket connection, but not between a server/browser, but two golang programs?
Or advise another technology so that it would be possible to send json data over the channel.

Thanks

You will do the same anyway. I just already made an abstraction.

Answer 2

websocket is only if you need https compatibility.
If over the network:
gRPC if protection is needed.
Or just Google Protobuf - it's very fast.
msgpack is like a protobuf, but without the need to describe the protocol, it's like a binary json.
There is also gotalk
If everything is on one physical computer, then unix sockets.
Only the term "real time" means something completely different.
websocket a priori cannot be "real time" since it is a network protocol.
