Whenever I start to learn a new technology I almost every time find it demotivating the way the documentations and references are organized: nested repeated, redundant and confusing. So, I decided make a short list of links that I will create after giving a thorough visit on the official website of that technology.

  1. The root directory of the project is where WORKSPACE file is created.
  2. All path is relative to the root directory.
  3. BUILD is located per package.

Test a gRPC server with grpcurl tool

grpcurl tool usages

I have a grpc server running at 0.0.0.0:50051. I'll show how you can use grpcurl to test it. Before that, install grpcurl (mybe using go).

  1. List services the server provides:
user@matin ~/o/g/examples ((v1.55.1))> grpcurl  -plaintext localhost:50051 list
grpc.health.v1.Health
grpc.reflection.v1alpha.ServerReflection
helloworld.Greeter
