📚 Go Design Patterns 🎯Behavioral Pattern ← Command Pattern 📋 All Patterns Observer Pattern → What is Chain of Responsibility? The Chain of Responsibility pattern is a behavioral design pattern that allows you to pass requests along a chain of handlers. Each handler decides whether to process the request or pass it to the next handler in the chain. This pattern decouples the sender of a request from its receivers by giving multiple objects a chance to handle the request. ...

Go Concurrency Patterns Series: ← Select Statement | Series Overview | Fan-Out/Fan-In → What is the Pipeline Pattern? The Pipeline pattern is a powerful way to structure concurrent data processing by breaking work into stages connected by channels. Each stage runs in its own goroutine, receives data from an input channel, processes it, and sends results to an output channel. This creates a chain of processing stages that can run concurrently, dramatically improving throughput. ...

Go Concurrency Patterns Series: ← Channel Fundamentals | Series Overview | Pipeline Pattern → What is the Select Statement? The select statement is Go’s powerful tool for handling multiple channel operations simultaneously. It’s like a switch statement, but for channels - it allows a goroutine to wait on multiple communication operations and proceed with whichever one becomes ready first. Think of select as a traffic controller at an intersection, managing multiple lanes of traffic (channels) and allowing the first available lane to proceed. This enables non-blocking communication, timeouts, and elegant multiplexing patterns that are essential for robust concurrent programs. ...

Go Concurrency Patterns Series: ← Goroutine Basics | Series Overview | Select Statement → What are Channels? Channels are Go’s primary mechanism for communication between goroutines. They embody Go’s concurrency philosophy: “Don’t communicate by sharing memory; share memory by communicating.” Think of channels as typed pipes that allow goroutines to safely pass data back and forth. Channels provide both communication and synchronization, making them incredibly powerful for building concurrent applications. They’re type-safe, can be buffered or unbuffered, and support directional constraints for better API design. ...

Go Concurrency Patterns Series: Series Overview | Channel Fundamentals → What are Goroutines? Goroutines are lightweight threads managed by the Go runtime. They’re one of Go’s most powerful features, allowing you to write concurrent programs that can handle thousands of simultaneous operations with minimal overhead. Think of goroutines as extremely efficient workers that can run independently while sharing the same memory space. Unlike traditional threads that typically consume 1-2MB of memory each, goroutines start with just 2KB of stack space and grow as needed. This efficiency allows Go programs to spawn millions of goroutines without overwhelming system resources. ...

📚 Go Design Patterns 🔨Creational Pattern ← Adapter Pattern 📋 All Patterns Strategy Pattern → What is Builder Pattern? The Builder pattern is a creational design pattern that constructs complex objects step by step. It allows you to produce different types and representations of an object using the same construction code. Think of it like assembling a custom computer - you choose the CPU, RAM, storage, and graphics card piece by piece to build exactly what you need. ...

📚 Go Design Patterns 🎯Behavioral Pattern ← Builder Pattern 📋 All Patterns Decorator Pattern → What is Strategy Pattern? The Strategy pattern is a behavioral design pattern that defines a family of algorithms, encapsulates each one, and makes them interchangeable. It lets you select algorithms at runtime without altering the code that uses them. Think of it like choosing different routes to reach the same destination - each route (strategy) gets you there, but some might be faster, cheaper, or more scenic. ...

📚 Go Design Patterns 🏗️Structural Pattern 📋 All Patterns Decorator Pattern → What is Adapter? The Adapter pattern is probably the most used design pattern in software engineering. It allows objects/classes of different abstracts/signatures/blueprints to collaborate. ...
