How to broadcast in gRPC from server to client?

Question

I\'m creating a small chat application in gRPC right now and I\'ve run into the issue where if a user wants to connect to the gRPC server as a client, I\'d like to broadcast

Another approach is to spawn a grpc-server on client side too. On app-level you have some handshake from client to server to exchange the clients grpc-server ip and port. You probably want to create a client for that address at this point and store the client in a list.

Now you can push messages to the clients from the list with default unary RPC calls. No [bidi] stream needed. Pros:

• Possible to separate the clients "Push"-API from the server API.
• Unary RPC push calls.

Cons:

• Additional "server". Don't know if that is possible in every scenario.
