While having a vibe of a mad genius might be tempting, reinventing the wheel is usually not the best way to approach designing your software. The chances are that somebody already had the same problem as you and solved it in a smart way. Such best practices, when formalized, are called design patterns. Today we look into […]
As discussed in the previous part of this series, there are many design patterns out there. Some of them fit well into the JavaScript language, and they are often used. In this article, we discuss the factory method pattern and show some of its use-cases. We also implement it in TypeScript. There seems to some confusion regarding […]
The essential thing when approaching design patterns is to utilize them in a way that improves our codebase. The above means that we sometimes can bend them to fit our needs. The Facade design pattern is commonly associated with object-oriented programming. That doesn’t change the fact that we can take its fundamentals and apply them […]
When we are cold, we put on a shirt. If that’s not enough, we put a coat on top. Decorators work similarly. In this article, we discuss the principles of the decorator design pattern and talk about their implementation in TypeScript. We also briefly mention the JavaScript implementation of decorators using Babel. The basics of […]
The Observer pattern is common among various native JavaScript features and many libraries. The above is just one of the reasons to look into it more. In this article, we learn the principles of the Observer pattern. We also add some TypeScript typings to it, to make it more bug-proof. The core principle of the […]
