Scalac's blog

What started as taking an online course just to be updated with the latest on a framework I like, turned out to be a lot of food for thought. And, ultimately, a good exercise regarding the best software development practices like separation of concerns, functional programming, and the practical limits of verifying the correctness of our software in compile time.

In this article, I’m going to introduce the main concepts behind this paradigm using the Scala programming language (In fact this was the language chosen as the Ruby replacement by Twitter :)).

Scalac and Ziverge have been partners and friends for a long time. We have sponsored events such as ZIO Hackaton, and Functional Scala. As Scalac we have delivered plenty of talks about ZIO at conferences and meetups such as Scale by the Bay, Functional World, and Functional Tricity. We have published a 1st ZIO ebook […]

In this article, we compare Tapir with endpoints4s. We highlight the differences by providing examples and explanations for the most common features you would like to have in your REST API. Both libraries only require you to describe the communication protocol in Scala. Once the communication protocol is written, you need to wire it with a specific HTTP Server (such as Akka HTTP) and/or body parsing (e.g. Circe). In the end, the library produces clients, documentation, and servers for you with implementations of your choices.

Together with Ziverge Inc., we're more than happy to invite you to the first ZIO Hackathon 2020 after the official launch of the 1.0 version that took place on August 4, 2020. The whole ZIO community was waiting for this moment for almost three years, but here we are!

You have probably encountered this problem while working with SBT and bigger projects. I’m talking about compilation times and test execution times, in other words, having to wait instead of working. Imagine working with a build tool that rebuilds only what is necessary, using a distributed cache, so if module A is built by one […]

There are plenty of frameworks you can base your application on in Scala, and every one offers a different flavor of the language with its own set of patterns and solutions. In this blog post, you will learn how to structure a command-line application using ZIO.

All of us are eager to start writing real-world applications using ZIO (Scala library). But ZIO is still quite new, and its ecosystem is still incomplete. So while we wait for ZIO-HTTP and ZIO-JDBC (or whatever else comes in the future) to happen, we will have to end up integrating ZIO with other frameworks that can communicate with the outside world. In this article, I want to explore what this kind of integration might look like for two of the most popular libraries - Slick and Akka HTTP.

Many people think that GraphQL is ‘something’ related to Graph Databases, in my opinion they’re wrong. GraphQL is to Graph DB like Javascript to Java. Are based on similar concepts, but are used for completely different things.In short: GraphQL is a query language for APIs, optimized for performance, designed and open-sourced by Facebook. In GraphQL you can ask server for connected data and you’ll get in response only what you’ve asked for. Not more. Great! Isn't it?

Welcome to our second article about Keycloak Server! Previously, we’ve learnt to setup the server and make use of it in a webapp -this time, we’re going to create a matching back-end API and also learn a little bit about the OAuth2/OpenID magic that powers our entire authn/authz mechanism. So let’s get started!
