Roughly about two years ago, I wrote an article called “Why using Spring’s @Value annotation is bad“. I described why you should avoid @Value annotations all throughout your code. By using @Value annotations in services, controllers and other Spring components, you will scatter your configuration through the complete application. In the worst case, you will […]

In AngularJS this is simply a function which returns an object with methods. In my opinion, this is the cleanest way to create […]
Program to an interface, not an implementation. This short sentence, introduced in 1994 by the GoF, is one of the most important design principles in software development. However, I have seen several projects where this principle has gone wrong. Here’s why: Interface vs. Interface If you come from a Java background like myself and you […]
Whenever you build software, you want to create reusable and independent components. In the world of user interfaces, those components are often called widgets. Here’s an example how we can achieve this with AngularJS. An example Let’s say we have an online shop where a customer can make an order. To do so, the customer […]
