gRPC in Go Tutorial

Welcome to this repository! This is a comprehensive guide designed to teach you gRPC in Go. gRPC is a high-performance, open-source universal RPC framework developed by Google. In this tutorial, we will cover everything from the basics of protocol buffers to the complexities of bi-directional streaming.

Getting Started

Before we start, make sure you have Go installed on your machine. If not, you can download it from the official Go website. You will also need to install the protocol buffer compiler protoc from the protocol buffers GitHub repository.

What is gRPC?

gRPC (Google Remote Procedure Call) is an open-source remote procedure call system developed by Google. It uses Protocol Buffers (protobuf) as its interface definition language, allowing developers to define services and message types in .proto files. gRPC supports four kinds of service method which are Unary RPC, Server streaming RPC, Client streaming RPC, and Bidirectional streaming RPC.

Why gRPC?

gRPC has many advantages over traditional HTTP/JSON APIs:

• Performance: gRPC uses HTTP/2 for transport and Protocol Buffers as its interface definition language, making it faster and more efficient than JSON.
• Streaming: gRPC supports server-side, client-side, and bi-directional streaming.
• Language-agnostic: You can generate gRPC client and server code in many languages, including Go, Java, C++, Python, Ruby, etc.

What's the Next Step?

If you follow the table of contents and go through each section of this tutorial, you will gain a solid understanding of gRPC by the end. This knowledge will equip you to create efficient and high-performing microservices using gRPC in Go.
