Cross-cutting concerns are these annoying, mostly technical requirements that have to be considered time and time again for things like authentication, logging, or error treatment. Of course, no one wants to have to repeat method calls necessary for these all the time. Ideally, they are activated automatically. In this article, I will demonstrate three different Angular mechanisms that make this possible in an elegant way: Guards, HTTP Interceptors, and Directives. All of the examples shown can be found in the GitHub repository [1].

Using a continuous integration (CI) server for backend systems has been an established best practice for a very long time. As the complexity and the scope of modern web frontends increases, so does the need for professional development techniques. This includes working with test-driven development, CI servers, and automated processes. In this article, we will use an example of Angular and GitLab CI to see how build automation can be implemented.

In the first part of this tutorial, we learned all about where Vue.js comes from and how to classify it. Now, we’ll be focusing on the component model of Vue.js as well as the Single File Components, which are very valuable tools used to write maintainable and extensible source code.

There are many approaches to cross-platform development, Progressive Web Apps are just one of them. Have you ever considerd building a PWA? You certainly should – browsers are everywhere today and make it really easy to reach a broader audience with your mobile app. Not sure yet? Watch this keynote from iJS Munich 2018 and learn more about PWAs from Maxim Salnikov.

Statistics and other data mining approaches help us make sense of this treasure trove of information. As data requirements continue to evolve, we should expect that our analytical tools keep pace. In this article, we will explore how to use stdlib for calculating real-time statistics.

Vue.js is a framework for web applications that enables component-oriented development based on JavaScript. It’s adaptable, especially lean and universally applicable. Of course, Vue.js is also very performant. So, it’s high time that we take a closer look at this framework. In part one of this two-part tutorial, we give a systematic introduction for the popular JavaScript framework.
