Summary
In this chapter, we created templates for our future servers and clients. The goal was to write the boilerplate code and set up our build so that we can generate code and run our Go applications.
We saw that we can use protoc manually to generate Go code and use it with our application. We then saw that we can make the process a little bit smoother by using Buf to generate the code for us. Finally, we saw that we can use Bazel to both generate our code and run our application in a single step.
Finally, we saw that we can use multiple ServerOptions and DialOptions to tweak the server and client. We mostly looked at grpc.Creds and interceptors, but there are a lot more options that we can check in the grpc-go repository.
In the next chapter, we will see how to write each type of API provided in gRPC. We will start with unary APIs, then check server and client streaming APIs, and finally, see how to write bidirectional streaming endpoints.
