How can I update protobuf file for client when server changed

I'm new in microservices ecosystem and I've just start study about gRPC. But I have a problem when I try to understand gRPC and Protobuf workflow.

First, I have a server and a client talk to each other via gRPC with NodeJS. Then I got a problem with my server so I have to fix it. But unfortunately, I have to change protobuf file too because I realize that error come from my gRPC Service.

So, for now I'm change protobuf file in both client and server manually. But I want to change(sync) proto file in client automatically(that's microservices, right?).

Please show me your method to make it auto! :(
