gRPC With Go Crash Course

gRPC With Go Crash Course

In this crash course, we'll cover everything you need to know about gRPC and integrating it with your Go applications.

Each of the sub-articles below are written in a way that they are independent from one another, so if you're interested in only going through a specific part of the course, feel free to do so.

The only article which is mandatory is the Introduction, which covers what kind of application you'll be building as well as what kind of software you need to install/configure to avoid any technical issues throughout the course.

If you encounter any issues or bugs in the article/code, feel free to open an issue in the Github repo for this course.

If you enjoy the course & want to support me I'd be more than grateful if you ⭐ the repo, share the series, say thanks on Twitter or sponsor my work 🙏

gRPC with Go Crash Course – Bidirectional Streams

gRPC with Go - Bidirectional Streams

This article is part of the series gRPC With Go Crash Course

In this part of the course, you will implement the most challenging RPC routine type which gRPC has to offer - bidirectional streams.

These routines are used to achieve bidirectional client-server communication - meaning that communication can flow both ways. A way to achieve this using traditional HTTP technologies is via web sockets. With gRPC, you have support for such communication natively.

gRPC With Go Crash Course – Unidirectional Streams

gRPC with Go - Unidirectional Streams

This article is part of the series gRPC With Go Crash Course

In this part of the course, you will implement slightly more challenging RPC routines which involve utilising the gRPC streaming capabilities.

These are essentially a way to achieve client-side or server-side pagination. However, in contrast to normal HTTP APIs, in gRPC these streaming utilities are first-class citizens rather than a useful add-on (e.g. via web sockets).

There is also support for bidirectional streams, which we will explore in the follow-up exercise. In this one, we’ll focus on unidirectional (client-side/server-side) streaming RPCs.

gRPC With Go Crash Course – Service Schemas

gRPC with Go - Service Schemas

This article is part of the series gRPC With Go Crash Course

In this article, you will create a gRPC/Protobuf schema for a small micro service system for an online casino. 

The scope of the article is to: 

  • Create the service schemas
  • Correctly generate the protobuf Go sources
  • Implement the gRPC servers/clients for the appropriate microservices
  • Integrate the microservices with each other

gRPC With Go Crash Course – Introduction

gRPC with Go - Introduction


This article is part of the series gRPC With Go Crash Course

In the following set of articles, you'll learn how gRPC works by building several simple web applications and hook them together using gRPC.

The articles won't go into details of what gRPC is and what's its purpose. There's a lot of existing material on the subject already. Instead, they focus on helping you get some real practice using gRPC, integrating it into your own applications & understanding the core mechanisms it provides.

First, we'll cover what we're about to build & the environment setup you'll need for the rest of the articles.

Additionally, have in mind that all the parts of the course are written in a way that they are independent from each other. So if you're not interested in the whole course and want to jump straight to Bidirectional Streams (for example), feel free to do so.

Hands-on gRPC at Gophercon Israel 2021

Gophercon Israel 2021

I'm super excited to announce that I'll be leading a workshop at Gophercon Israel 2021 (https://www.gophercon.org.il/) this year with "Hands-on gRPC with Go".

In this workshop, participants will be building several web services, which are communicating using the gRPC protocol. They'll explore all different communication types the protocol provides, giving them everything they need to know to integrate and start using gRPC in their own web services.

So if you want to learn gRPC and your hands are itching, grab your ticket and I'll see you there!
