Implementing a https enabled redirect service using Firebase

Posted on by

More and more web-traffic is moving to https instead of http protocol. Because users are using a modern browser that defaults to https or a browser extension like Https-By-Default . A great development from a security- and privacy perspective. But with some side effects as it pointed out that the redirect service offered by our hosting provider does not fully support https which causes a security warning.

Although valid commercial solutions are available this fully triggered my (somewhat rusty) not invented here syndrome. Performing the redirect sounds like a suitable functionality for a simple cloud function. With the additional requirement that it should be able to host the cloud function on the (sub)domain(s) we want to use for our redirects.

This blog post will describe the simple steps to develop a cloud function using Firebase Functions and expose it through Firebase Hosting over https using a valid certificate.

Implementing architectural fitness functions using Gradle, JUnit and code-assert

Inspired by Neal Ford’s presentation at our Change is the Only constant event I started experimenting with architectural fitness functions. An architectural fitness function provides an objective integrity assessment of some architectural characteristic(s). If you want to take a deeper dive into evolutionary architectures including fitness functions take look at Neals book: Building Evolutionary Architectures: Support Constant Change. Neal’s slides contained an example of verifying package dependencies from a Unit Test using JDepend.

Exploring the Vert.x MQTT server project

In the last few years we used Vert.x to prototype and develop several IoT related projects. Most of the projects use MQTT for lightweight messaging between the connected devices (or things ;)) and the applications. The messaging is handled by an external broker liker Mosquitto. Instead of using an external broker it’s now possible to connect MQTT enabled devices directly to Vert.x using the Vert.x MQTT server project. Although the project is still in Tech Preview we’ll show you how use it to create a MQTT server within Vert.x. At first we add the snapshot repository to our build.gradle file.

Het ontstaan van de passie voor het moderne maken

Als JDriven ervaren we elke dag hoe schaars het talent is dat nodig is om onze klanten optimaal te ondersteunen. Deels omdat we op zoek zijn naar echte specialisten maar vooral omdat we verwachten dat collega’s een passie hebben voor hun vak en erg gemotiveerd zijn om mooie dingen te maken. Deze passie is voor ons essentieel en wat mij betreft is dit de basis van succesvol software ontwikkelen oftewel het moderne maken. Het ontwikkelen van een specialisme vergt tijd. Het vindt eigenlijk pas plaats tijdens een studie en wordt continu ontwikkeld tijdens je verdere carrière. Maar de passie voor het vak, dat wat mijn collega’s uniek maakt, wordt al veel eerder gelegd. Zonder uitzondering blijkt het ontstaan van deze passie te herleiden naar één of twee toevallige gebeurtenissen in hun jeugd: een ouder met een passie voor electronica, een vriendje (of vriendinnetje) met een computer etc..

This year we attended Devoxx 2013 with a total of 9 JDriven colleagues. After more than a week we finally recovered from a vast amount of great sessions, personal encounters and  'some' Belgian beer. Looking back at Devoxx we had a great conference and like to thank the Devoxx team for making this possible. It was also good to notice that the majority of the sessions are related to subjects that drive us at JDriven, during our daily job and while further developing our expertise and craftsmanship, to name a few: Continuous Delivery, AngularJS, RESTful API's, Gradle, Groovy, Grails, Java 8, Java EE.
