In the first two articles of this series, we built our first gRPC service in Kotlin and explored the essentials of Protobuf schema design from optional and repeated fields to enums, oneof, maps, and how Read more…
In the previous (first) article of this series, we introduced gRPC and Protocol Buffers by building a minimal Kotlin gRPC service: a simple NoteService that allowed creating and retrieving notes. Now that we’ve covered the Read more…
This is the first article in a hands-on series where we’ll explore how to build gRPC services using Kotlin. The series is designed to help you understand not only the technical how-to, but also the design choices behind Protocol Read more…
In the previous article, Taking Kotlin Builders to the Next Level: A Type-Safe DSL Approach, we explored how Kotlin’s type-safe builders allow you to build expressive and concise DSLs. But as soon as your DSL Read more…
You might recall my Simplifying the Builder Pattern article about using Kotlin Data Classes as a simpler version of the Builder pattern. You saw how named parameters and default values removed much of the ceremony Read more…
In the previous chapters, we’ve seen cases where Kotlin’s features can profoundly alter traditional design patterns to a simpler, more concise and expressive solution. In this final article of the series, we’ll explore how Kotlin’s Read more…
The Observer Pattern is a behavioral design pattern where an object (the subject) maintains a list of its dependents (observers), and notifies them automatically of any state changes. This pattern ensures that multiple objects are Read more…
The Proxy Pattern is a structural design pattern in object-oriented programming. It provides a surrogate or placeholder for another object to control access to it. This pattern creates a ‘proxy’ object that acts as an Read more…
The Decorator Pattern is a flexible alternative to subclassing for extending functionality. It allows behavior to be added to individual objects without affecting the other objects from the same class. It is particularly helpful when Read more…
We use the Prototype Pattern when creating new instances from scratch is more expensive than copying existing ones. So, instead of instantiating new objects, you can have a prototype from which clones/copies are made. Traditional Read more…
The Builder pattern is a design pattern used to construct complex objects step by step. It separates the construction of an object from its representation, allowing the same construction process to create different types. When Read more…
The Singleton pattern is a design pattern that ensures a class has only one instance, while providing a global point of access to it. This pattern is used when exactly one object is needed to Read more…
In the evolving world of back-end development, the choice of programming language plays a pivotal role in defining the efficiency, expressiveness, and overall experience of a developer. Kotlin, a modern language that interoperates seamlessly with Read more…
