Welcome back to the fourth and final part of the "gRPC with Go" series. Before proceeding with the rest of the app, let's have a quick recap of what you've done so far:

In part one, you wrote the Protobuf definitions and generated Go code stubs. You also wrote the reverse proxy for REST clients.

In part two, you connected your app to a PostgreSQL database and wrote the non-streaming endpoints of the gRPC server, and you wrote the streaming endpoints and completed the server.

In this last installment, you'll write the gRPC client and test the whole app.
