RPC Calls Help

[robdevsmith]

protobuf.js version: <6.8.8>

Hello guys,
I am newbie with protobuf, is there any example of how to implement the rpcImpl() function to consume my gRPC services ?
I already can use grpc-node package as client with success, but I can't use it in my webpack project.
What package should be an option to integrate with protobufjs to make roc calls ?

Or what am I doing wrong ?
