gRPC [Golang] Master Class Build Modern API and Microservices - [Solution] Sum API

This video tutorial guides viewers through creating a simple calculator service using gRPC. It covers setting up the project, defining protocol buffers, generating code, and implementing both server and client components. The tutorial demonstrates how to handle sum requests and responses, providing a practical example of RPC communication. The video concludes with a brief introduction to gRPC's streaming capabilities, setting the stage for more advanced topics.

What is the first step in setting up a calculator service using RPC?

• Creating a calculator.proto file

• Implementing the client

• Creating a calculator PB folder

• Generating code from protocol buffers

What is the purpose of defining a sum request in protocol buffers?

• To specify the numbers to be added

• To create a new service

• To store the result of the sum

• To define the server's response

Which command is used to generate code from the protocol buffer file?

• generate calculator.pb.go

• go run calculator.proto

• compile calculator.proto

• protoc --go_out=.

What is the role of the sum function in the server setup?

• To initialize the server

• To connect the client to the server

• To handle sum requests and return responses

• To define the protocol buffer syntax

How does the client interact with the server to perform a sum operation?

• By using a web interface

• By modifying the server's code

• By directly accessing the server's database

• By sending a sum request and receiving a sum response

What is the expected output when the client sends a sum request with numbers 5 and 40?

• A sum response of 55

• A sum response of 50

• A sum response of 45

• A sum response of 35

What is the next topic to be covered after implementing the sum function?

• Error handling in RPC

• gRPC streaming capabilities

• Security in RPC communication

• Advanced calculator functions
