Developing a gRPC Client

Let’s learn how to develop a gRPC client in Go.

We'll cover the following

Coding example
Testing the gRPC server with the client
Let’s try our code

This lesson presents the development of the gRPC client based on the api.proto file presented earlier. The main purpose of the client is to test the functionality of the server. However, what is really important is the implementation of three helper functions, each one corresponding to a different RPC call, because these three functions allow us to interact with the gRPC server. The purpose of the main() function of gClient.go is to use these three helper functions.

Coding example

So, the code of gClient.go is the following:
