When I started working in Go, the community was not looking positively on techniques like DDD (Domain-Driven Design) and Clean Architecture. I heard multiple times: “Don’t do Java in Golang!", “I’ve seen that in Java, please don’t!". These times, I already had almost 10 years of experience in PHP and Python. I’ve seen too many bad things already there. I remember all these “Eight-thousanders” (methods with +8k lines of code 😉) and applications that nobody wanted to maintain.
In case you’re here for the first time, this post is the next in our Business Applications in Go series. Previously, we introduced Wild Workouts, our example application built in a modern way with some subtle anti-patterns. We added them on purpose to present common pitfalls and tips on how to avoid them. With this post, we begin refactoring of Wild Workouts. Previous articles will give you more context, but reading them isn’t necessary to understand this one.
Welcome in the third and last article covering how to build “Too Modern Go application”. But don’t worry. It doesn’t mean that we are done with showing you how to build applications that are easy to develop, maintain, and fun to work with in the long term. It’s actually just the beginning of a bigger series! We intentionally built the current version of the application to make it hard to maintain and develop in the future.
Welcome in the third article form the series covering how to build business-oriented applications in Go! In this series, we want to show you how to build applications that are easy to develop, maintain, and fun to work in the long term. Two weeks ago I described Wild Workouts – a fully working application that we created especially for this articles series. One week ago Miłosz described how to deploy this application using Terraform.
In the previous post, Robert introduced Wild Workouts, our example serverless application. Every week or two, we will release new articles related to this project, focusing on creating business-oriented applications in Go. In this post, I continue where Robert left off and describe the infrastructure setup. We picked Google Cloud Platform (GCP) as the provider of all infrastructure parts of the project. We use Cloud Run for running Go services, Firestore as the database, Cloud Build as CI/CD, and Firebase for web hosting and authentication.
Welcome to the first article from the series covering how to build business-oriented applications in Go! In this series, we want to show you how to build applications that are easy to develop, maintain, and fun to work in the long term. The idea of series is not to focus too much on infrastructure and implementation details. But we need to have some base on which we can build later. In today’s article, we start by covering some basics tools from Google Cloud that can help us to do that.
If you compare MySQL or PostgreSQL with Kafka or RabbitMQ, at first, it seems they are entirely different software. And usually, that’s true, as you would use them for quite different tasks. What they have in common is processing streams of data, and they specialize in specific ways of doing it. While Kafka and RabbitMQ are popular examples of Pub/Subs (also known as message queues or stream processing platforms), I’d like to share some patterns for using SQL databases as Pub/Subs as well.
54 days of work, 12,909 lines of code, 47 Monsters and 42 KFC Twisters later finally it is Watermill v0.3.0! To keep it short, let’s go through the changes. One important thing: at the end of this post there is a 3 question survey. Please take a moment to fill it out, it will help us make Watermill even better. CQRS component One of the most important parts of the v0.
This time I’d like to touch on a few more advanced topics related to GitLab CI. The common theme here is implementing custom features within your pipeline. Again, most of the tips are specific to GitLab, but some could be easily applied in other CI systems as well. Running integration tests Checking your code with unit tests is usually easy to plug into any CI system. It usually is as simple as running one command built in your language’s toolset.
This post is a quick how-to for starting a new project in Go. It features: Hot code reloading Running multiple Docker containers with Docker Compose Using Go Modules for managing dependencies It’s best to show the above working together with an example project. We’re going to set up two separate services communicating with messages over NATS. The first one will receive messages on an HTTP endpoint and then publish them to a NATS topic.
