Testing components is the most challenging yet unavoidable task when developing Angular applications. I will show you a couple of strategies and a mental model to overcome that. The tricky part of components comes from their dual nature (presentation with a template and logic with a class). Another obstacle to…

Traditionally, Angular applications were tested with Karma and Jasmine. But, in the last years, Jest has become a popular alternative. The main reasons for using Jest with angular are: Jest is faster, has a better developer experience, and has wider usage by not being specific to a single framework. In…

How do objects behave? At runtime, their life is about instantiating, calling, and being part of processes bigger than themselves. It is a complex and critical matter involving our programs’ flow control and data manipulation. Behavioral patterns guide us on how instances communicate with others. Well-designed applications end up with…

How to compose objects? It’s an excellent question; Thinking about composition is, first and foremost, the right way to relate classes. Structural patterns guide us on how and when to wrap some instances in others. Well-designed applications end up with dozens of classes. Some are like legacy-sealed stones, while others…
