This repository demonstrates a simple implementation of a gRPC-based microservice for User CRUD (Create, Read, Update, Delete) operations. We have used Go and Cobra to manage both server and client commands in the same binary.
-
Cobra for Command Management:
- We use Cobra to organize the project into commands.
- Two main commands:
server: Starts the gRPC server.client: Sends requests to the gRPC server (like creating or retrieving users).
-
gRPC User Service:
- The gRPC service provides basic CRUD functionality for user entities.
service/user_service.gocontains the logic for the following operations:CreateUser: Adds a new user.DeleteUser: Deletes a user by ID.GetUser: Retrieves user information by ID.UpdateUser: Updates user details.
-
Proto Definitions:
- The gRPC service is based on a
user.protofile (located in theuser/directory). - This file defines the
UserServiceand the request/response types for the operations.
- The gRPC service is based on a
- Install Dependencies: Make sure you have Go installed and then run:
go mod tidy- Run the gRPC Server: Use the server command to start the gRPC server.
go run main.go server- Run the gRPC Client: Use the client command to send requests to the server. For example, to create a user:
go run main.go clientNote: To generate gRPC code, ensure you generate the necessary gRPC files from the proto:
make generate_grpc_code
