A Gentle Introduction to Web Services With Go

When you're deciding on a technology to use for your project, it helps to have a broad understanding of your options. You may be tempted to build a web service in Go for performance reasons - but what would that code actually look like? How would it compare to languages like Ruby or JS? In this article, Ayooluwa Isaiah gives us a guided tour through the building blocks of go web services so you'll be well-informed. https://www.honeybadger.io/blog/go-web-services/

Evaluating Go's Package Management and Module Systems

When you're evaluating a language for your next project, few things are more important than available third-party libraries and the package manager that ties them together. While early versions of Go lacked a package manager, they've made up for lost time. In this article, Ayooluwa Isaiah introduces us to Go's module ecosystem to help us decide if Go is "a go" for our next project. https://www.honeybadger.io/blog/golang-go-package-management/

Why Rubyists Should Consider Learning Go

These days fewer and fewer web developers get to specialize in a single language like Ruby. We use different tools for different jobs. In this article, Ayooluwa Isaiah argues that Go is the perfect complement to Ruby. The developer who knows both is in a great position to handle almost any back-end challenge. https://www.honeybadger.io/blog/rubyist-learn-go/

Logging in Go: Choosing a System and Using it

Go has built-in features to make it easier for programmers to implement logging. Third parties have also built additional tools to make logging easier. What's the difference between them? Which should you choose? In this article Ayooluwa Isaiah describes both of these and discusses when you'd prefer one over the other. https://www.honeybadger.io/blog/golang-logging/

Deploy a Buffalo App to Heroku

Deploy a Buffalo App to Heroku from Antonio Pagano.

A lot of things have changed in the Buffalo ecosystem since my last post on how to deploy to Heroku from Gitlab.

Indeed, everything has changed since I posted how to deploy from gitlab repo into Heroku with the birth of the buffalo-heroku plugin. In this post I will try and describe how to use it to deploy your buffalo app to Heroku.

API gateway examples with Traefik, Ambassador and Envoy

API gateway acts as a reverse proxy, routing API requests from clients to services. Usually it also performs authentication and rate limiting, so the services behind the gate don't have to. Check out short tutorials of Ambassador and Traefik that aim to tackle the problem, also there is Envoy example in https://github.com/marselester/apigate.

Error handling example in DDD-style project with Go kit

Ben Johnson wrote Failure is your Domain post that explores the purpose of errors for app developers (error code), operators (stack trace), end users (human-readable message). https://github.com/marselester/ddd-err is an attempt to implement those ideas using Go kit.

How to structure Go projects

New developers who come with Python/Ruby experience look for familiar framework concepts that fit their mental picture of how a web application should be structured. For some reason the same concepts do not resonate with Go. How to structure Go projects blog post shows that DDD (Domain-Driven Design) flavored approach is endorsed according to talks given at GopherCons.

Kafka for Gophers slides

Kafka for Gophers presentation provides an overview of how to achieve reliable data delivery with Apache Kafka in Go. If you've ever felt uneasy about what might happen with your service when a message is lost or written more than once, you should read "Kafka: The Definitive Guide" book. When it comes to choose a Go library to work with Kafka, the decision could be tough. I would recommend to check out https://github.com/segmentio/kafka-go.
