gRPC Unary API

A simple gRPC Unary API which uses Repository pattern.

Steps to run the project:

• to run the grpc server, run go run main.go in the cmd directory to run the main.go file.
• run go run main.go in the client/user directory to run the grpc client for User detail(GetUser).
• run go run main.go in the client/users directory to run the grpc client for a list of User details(GetUsers).
• to run the tests, run go test in the cmd directory to run the main_test.go file.

Design Pattern

• I've used Repository pattern in this project to create a layer between database specific logic and business logic in the app.
• I've used an in-memory repository implementation.
• Using this pattern, we can treat repositories as adapters which can be changed in the future without having to touch the business logic(handlers). For example, to use MySQL in future, we can create a MySQL repository and use it instead of the in-memory repository.
