Server and Dial options

We touched upon ServerOption and DialOption briefly with the grpc.ServerOption object and the grpc.WithTransportCredentials function. However, there are a lot of other options you can choose from. For readability’s sake, I will not go into detail about every one of them, but I want to present some major options that you will probably use. All ServerOptions can be found at the root of the grpc-go repository in the file called server.go (https://github.com/grpc/grpc-go/blob/master/server.go) and the DialOptions in the file called dialoptions.go (https://github.com/grpc/grpc-go/blob/master/dialoptions.go).

grpc.Creds

This is an option, on both the server and client sides, that we will use when we talk about securing APIs. For now, we saw that we can call grpc.WithTransportCredentials with an insecure.NewCredentials result, and this gives us an insecure connection. This means that none of the requests and responses are encrypted; anyone could intercept...
