Proxy pattern provides a surrogate or placeholder for another object to control access to it. It acts as an intermediary, adding functionality without changing the original object.
Here’s when and how to use it in real-world Go applications.
Continue readingBuilder pattern separates object construction from its representation. It allows creating different representations of an object using the same construction process.
Here’s how to implement it properly in Go with real-world examples.
Continue readingObserver pattern is one of the most useful behavioral patterns. It establishes one-to-many dependency between objects: when one object changes state, all dependents are notified automatically.
Here’s how to implement it properly in Go with real-world examples.

Tired of Redis queues losing messages? Fed up with RabbitMQ’s complexity? Need something that just works at scale? Meet NSQ - the message queue that powers Discord, Bitly, and other high-traffic systems.
While others struggle with queue complexity, you’ll learn when NSQ is not just useful, but absolutely perfect for the job.
Continue readingFacade Pattern is a simplified interface to a complex system. Instead of dealing with dozens of classes and methods, the client works with one simple facade that hides all the complexity inside.
It’s like a concierge at a hotel: you don’t call the laundry, restaurant, and housekeeping separately. You tell the concierge what you need, and they coordinate everything for you.
Continue readingSingleton is one of the most controversial patterns. Some call it an anti-pattern, others use it everywhere. Let’s explore how to properly implement Singleton in Go and when it’s actually needed.
Adapter Pattern solves the problem of interface incompatibility. You have code expecting one interface, and a library providing another. An adapter is a layer that makes them compatible.
