Introduction The Bridge pattern is a design pattern that is meant to “decouple an abstraction from its implementation so the two can vary independently”. To that end this pattern can use encapsulation, aggregation and also inheritance in order to separate…
Introduction The Adapter pattern is used to make one interface compatible with another. It allows objects with different, and therefore incompatible interface to work together. If you for example want to bring an existing class into your system with an…

Introduction The template method pattern is a behavourial design pattern which allows you to define the template, or the skeleton of an operation in a base class, while allowing the subclasses to override specific steps or all steps of the…
Introduction Sometimes, for reasons of efficiency, it can be quite handy to keep a pool, that is non-empty set, of initialized objects ready. This can be the case in for instance when you have database connections, which are expensive to…
Introduction In my previous post I described simple implementation of the Object Pool pattern. In this post I will extend this pattern using generics. It will become slightly more complicated, but also more flexible, and probably more solid. Implementation in…

Sometimes creating an object is expensive, either an object takes up a lot of resources, or costs time to initialize because of external dependencies, like web services or databases. Then it might be a good idea to construct the object…
Introduction Dependency Injection is simply said, the idea that your classes should depend on abstraction, i.e. the abstraction of a datasource for example, rather than on concrete implementations. This means that classes will depend on interfaces rather than on real…

Introduction In Design Patterns, the Iterator is a way of traversing over a container, that is access each of the container’s elements. It is used as a convenient way to traverse over lists or arrays, but it could also be…

Introduction In my previous two posts we set up a kubernetes deployment for a Django Rest Framework Application. If you have not followed along with those posts, the code can be found here. It is however highly recommended that you…
Introduction For the past couple of years I have been reading about Django and the Django Rest Framework, and especially about the good Developer Experience it offers. This of course spiked my curiousity, and I decided to perform a small…
