Dockerizing modern web apps

Most websites these days are Single Page Applications (SPA for short) where a single entry file handles all routes that a user might visit. Swept up in the ongoing trend of hosting in the cloud you might find yourself needing to “dockerize” your SPA. That is to say wrap it inside a Docker image and run it as a container.

Polling using RxJS

As observables are gaining more and more popularity in JavaScript we are looking to accomplish our everyday tasks using them and evaluating whether they are really worth all the hype. One task you might find yourself doing is polling the backend to know whether a longer running task has completed.

We will walk through an example of such a scenario and implement a solution using RxJS. On our way we will learn some basic operators for RxJS, and a few techniques as well as how to avoid a pitfall or two. At the end I will present a real-world example to show you how to implement what we learned in a specific scenario.

How I fell in love with an API-first CMS

The CMS (Content Management System) was one of the first building blocks of the content driven web. The CMS marked the move away from hardcoded HTML pages, and towards our modern web in which everyone has become a content creator. They are great for businesses because the competence of building websites and managing content could not only be split in theory, but also in practice. With a CMS, we can update our website on the fly — so there is really no justification for not using a CMS.
