Hello! In this post, I will explain the cost-effective method I use to host my Go web applications with varying levels of complexity, all starting from as low as $5 per month. This method also allows to easy deploy and scale your golang application.go hosting digitalocean docker
Since Go 1.19 we can use a new
103 (Early Hints) http status code when we create web applications. Let’s figure out how and when this could help us.
We are going to create a simple golang web server that servers some html content. One html page will be served with
103 header and another one without.
After loading comparison we will see how early hints can improve page performance.
I guess that almost everyone in the go community was exciting when Go 1.18 was released, especially because of generics. Some days ago I decided to try generics in the real-world application, by refactoring some of its pieces, related to a caching logic.go generics redis cache
This time, I will show you how to work with the maps in go effectively and prevent the occurrence of the data race errors. Data races happen when several goroutines access the same resource concurrently and at least one of the accesses is a write.go concurrent map data race
Recently, I discovered a surprisingly reliable memory caching solution, which I’m planning to use in all my further applications to increase performance. In this blog post, I will share some code examples of how you can integrate Ristretto caching library into your application.go caching ristretto performance
When we create a web application, usually, there a need to communicate with the users to inform them about the results of their actions. The easiest way to communicate - is to send messages. These messages might be warnings, errors, or just informational text. In this article, we will improve the UX of our user authentication application from the previous article by adding an error flash message when the user entered a wrong password and a success message after user authorisation.go echo flash messages
In this post, I’m going to show the way how we can implement a simple queue in Golang, using channels.go queue channel goroutine
In this article I’m going to show how easy we can sort strings alphabetically in different languages, using Go. It seems like an easy task if we want to sort English words, however, it’s not so trivial if we want to sort correctly strings with special characters or in other languages, i.e Cyrillic based.go sorting alphabetical sort
