WebSockets provide a full-duplex communication channel over a single TCP connection, enabling real-time communication between clients and servers. In this article, we’ll build an anonymous chat server in Golang using the net/http and golang.org/x/net/websocket packages, and we’ll style the chat interface using Tailwind CSS. Prerequisites Ensure you have Go installed on your system. You can download it from here. Also, make sure you have tailwindcss installed or you can link it via CDN....

IP throttling, also known as rate limiting, is a technique used to control the rate of requests from a client to a server. It helps prevent abuse, ensure fair usage of resources, and protect against denial-of-service attacks. In this article, we’ll explore how to implement IP throttling in Go using the net/http package and the golang.org/x/time/rate package, which provides a rate limiter implementation. Prerequisites Before we proceed, make sure you have Go installed on your system....

Error handling is an essential aspect of robust software development. In Go, error handling is straightforward yet powerful, thanks to the built-in panic and recover mechanisms, along with the ability to wrap errors for improved context. In this article, we’ll explore these error handling strategies in detail, along with comprehensive code examples. 1. Panic and Recover What is Panic? panic is a built-in function in Go that stops the ordinary flow of control and begins panicking....

In Go, interfaces play a significant role in achieving polymorphism and abstraction. They define a set of method signatures that a type must implement to satisfy the interface contract. In this article, we’ll delve into what interfaces are, why they are useful, explore the concept of empty interfaces, and discuss some common useful interfaces in Go, accompanied by comprehensive code examples. What is an Interface in Go? An interface in Go is a type that specifies a set of method signatures....

Concurrency is a powerful aspect of Go (Golang) that allows developers to execute multiple tasks concurrently, enabling efficient resource utilization and improved performance. In this article, we’ll explore two key concurrency primitives in Go: goroutines and channels. Understanding Goroutines Goroutines are lightweight threads managed by the Go runtime. They enable concurrent execution of functions or methods independently of other parts of the program. Goroutines are more lightweight than operating system threads, allowing Go programs to create thousands or even millions of them without significant overhead....

The Singleton pattern is a creational design pattern that ensures a class has only one instance and provides a global point of access to that instance. While Go does not have traditional classes like object-oriented languages, it does allow for the implementation of the Singleton pattern using various approaches. We are going to use Goroutines in testing our approaches in Multi-threading. In this article, we’ll explore different approaches to implement the Singleton pattern in Go, along with code examples....
