Original Article

This article explores how to use the gRPC framework with Golang for microservice communication. I build a simple note-taking application to demonstrate the advantages of gRPC over REST, understand its structure and components, and implement both a gRPC server and client. By the end of this tutorial, You will have a solid grasp of how to create efficient, action-based APIs using gRPC and the benefits of leveraging protocol buffers for data representation.

Key points:

• gRPC is a Remote Procedure Call (RPC) framework that provides better speed and efficiency than REST APIs.
• Protocol buffers offer more efficient binary data representation than text-based formats like JSON or XML.
• The tutorial guides You through implementing a gRPC client-server application in Go, including creating a Go project, implementing application logic, and implementing the gRPC server and client.
• The article also covers advanced topics, such as streaming with gRPC.
