httpyac VS grpcurl

There's also https://httpyac.github.io/ which has both standalone CLI and VS Code extension versions – might be interesting to explore.

Here is the github repo for httpyac [1]. Not sure why it's not part of the httpyac org that hosts the site.

grpcurl

The API server will be built and start running on port 50051. You can test the functionality using a gRPC client of your choice like grpcurl or Postman.

> What is the ubiquitous utility for interacting with gRPC? We have curl for REST. What is openAPI of gRPC?

grpcurl[1] combined with gRPC server reflection[2]. The schema is compiled into the server as an encoded proto which is exposed via server reflection, which grpcurl reads to send correctly encoded requests.

The whole idea behind the post is that accessing the gRPC service with regular tools is impossible. To test, we need a dedicated tool nonetheless. I found grpcurl. Let's install it and use it to list available services:

A simple GRPC client built using grpcurl.

You can use grpcurl to achieve this effect: https://github.com/fullstorydev/grpcurl

As I said before, the grpcurl utility is an equivalent to curl, but here instead of acting like an HTTP client (like curl), we use grpcurl as a gRPC client to test services from a running gRPC server. So, let’s use it to play a little bit more with our hello world.
