If you’re testing web apps then you need to know what the purpose of HTTP protocol is and how it works. Actually, in my first project I lacked this knowledge. However, since then I’ve realised how important it is and that’s the reason I want to share it with you. In this article I will […]

Async/await is a brand new way of handling asynchronous calls in JavaScript. If you don’t know how it works, in this article I will be providing some examples to help you get started.

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!

Providing authentication and authorization for the non-public-facing components of your application is an important part of many systems. But all major Scala frameworks come ready-equipped with some native tools for doing that, with complexity and comprehensiveness ranging from basic HTTP schemes with Akka HTTP’s SecurityDirectives to numerous Play plugins such as Deadbolt 2 or Silhouette.But it can be difficult to get what you need out of some of these. And if you have to relearn them for every new framework - it ain’t nice either.Learn how to overcome the additional overhead when moving to an unfamiliar tech stack!

If you’re testing web apps then you need to know what the purpose of HTTP protocol is and how it works. Actually, in my first project I lacked this knowledge. However, since then I’ve realised how important it is and that’s the reason I want to share it with you. In this article I will show you the basics of HTTP protocol. For example, how the BE (back-end) and FE (front-end) communicate, where you can see the data and how you can use this knowledge to add extra information to your bug tickets.

During the ReactConf 2018 the Hooks were presented and to be honest it has shaken up the React community. If you haven’t seen “React Today and Tomorrow and 90% Cleaner React With Hooks” video yet, then I encourage you to do so. Introducing stateless functional components in React 0.14 allowed us to create a smaller […]

S3 (Amazon’s Simple Storage Service) is a popular, widely used object storage service. Uploading a file and storing it on S3 in Akka Http traditionally involves temporarily storing a file before sending it to S3 service. This process can be simplified by using Alpakka AWS S3 Connector. In this post we will take a look at those two different […]

In this post, we’ll look at what the Typelevel ecosystem looks like in 2018, and how its various libraries interact with each other. In particular, we’ll focus on how we can compose some of these libraries to build a complete application, in a purely functional fashion. This will not be a tutorial for Cats (there […]

A pretty hot topic lately is machine learning – the inter-sectional discipline closely related to computational statistics that lets computers learn without being explicitly programmed. It has been found to be of significant use in the field of data analytics – from estimating loan and insurance risk to trying to autonomously steer a car in […]
