Explanation

This api is using grpcui for endpoint testing. Makesure you can run make command for simplicity. To run:

• Run go get
• Run make pb to generate the protobuf
• Run make run to spin up the api
• Run make test to see the testing result
• Run make grpcui to spin up the grpc interactive UI. To install grpcui, kindly follow this repository

The tests might not be too sophisticated due to I only focus on several important functions. Because it's a quite simple API, I designed the folder structure to be quite simple too, separating the service from the 'handlers'. Also I added some functionality like middleware (interceptors), config variables using .yaml file and simple api_key for security. Also I use makefile to make it easier to run on the terminal. Hope this satisfies your requirements. Thank you!

nb: don't forget to add api_key on the request header with value that exists in ./config/config.yaml :)
