When building a web application, connecting to a database is a fundamental step. In this guide, we’ll explore how to effectively connect to a database using Go, focusing on tools like golang-migrate, sqlc, and godotenv for environment management, alongside the Echo framework to set up a basic application. Setting Up Your Environment Before diving into the code, ensure your environment is ready. You’ll need Go installed on your system. The steps vary slightly between Windows, macOS, and Ubuntu, but generally, you can download the installer or package from the Go official website and follow the provided instructions.

Welcome to the world of Go programming, where building web APIs doesn’t have to be a daunting task! If you’re looking to get your hands dirty with some practical Go coding, you’re in the right place. Today, we’ll embark on a journey to create a simple yet powerful web API using Echo, one of Go’s most beloved web frameworks. Along the way, we’ll unravel the mysteries of the Service Repository and Factory patterns, making your code not just work, but work beautifully.

As we venture deeper into the world of Go programming, having covered the basics in the initial chapters, this third installment of our series aims to equip you with the skills necessary to harness Go’s powerful features: concurrency, error handling, and the newly introduced generics. These capabilities are pivotal in crafting robust, efficient, and versatile applications. Part 1: Embracing Generics for Flexible and Type-Safe Code The introduction of generics in Go 1.

Go modules have revolutionized the way Go developers handle dependencies, making it easier to manage, share, and collaborate on Go projects. This blog aims to demystify Go modules for newcomers and provide a detailed understanding of how they work, especially with the latest Go versions like 1.21 and 1.22. Introduction to Go Modules Introduced in Go 1.11, Go modules are the standard for dependency management in Go. They replace the old GOPATH-based approach, allowing for more flexibility in project structure, versioning, and package management.

Welcome back to our journey through Go programming! In Chapter 1, we dipped our toes into the basics. Now, it’s time to wade a little deeper. Chapter 2 builds on our foundation, introducing you to more complex concepts like multiple return values, variadic functions, and reinforcing our understanding of Go’s core components. Perfect for students ready to level up their Go expertise! we draw inspiration from Go by Example, an excellent resource for learning Go through annotated example programs.

Welcome to the exciting world of Go! This chapter is designed to kickstart your journey into Go programming, covering the essentials from “Hello, World!” to functions. Along the way, we’ll explore best practices and highlight some anti-patterns to avoid. Let’s dive in! Hello World Every programmer’s journey begins with the quintessential “Hello, World!” It’s a simple yet profound way to get acquainted with any new programming language.\ package main import "fmt" func main() { fmt.

Hello again, Rust enthusiasts! We’ve journeyed through the foundational concepts and dived into the advanced territories of Rust’s trait system in our previous posts. Today, we’re at the final frontier, ready to tackle the intricacies of mastering traits in Rust. This installment is all about navigating through edge cases, understanding best practices, and making the most out of Rust’s powerful trait system. So, let’s get started and wrap up our series with a deep dive into the art of mastering Rust traits.

Hey there! If you’ve been following along, you know we’ve been deep-diving into Rust, exploring its nooks and crannies. This time around, I’m switching gears to something more hands-on. I want to walk you through a curated list of projects that have not only sharpened my skills but promise to elevate yours from beginner to pro. 1. Building a Guessing Game with a Twist Alright, let’s dive into something that’s simple at first glance but has layers to peel back—a guessing game, but not just any guessing game.

Trait Objects and Dynamic Dispatch In Rust, polymorphism achieved through traits can take two forms: static and dynamic dispatch. Static dispatch is like knowing exactly what tool you’re going to use for a job, making it fast and efficient. Dynamic dispatch, on the other hand, is more flexible, allowing you to choose the right tool while the job is already underway. Understanding Trait Objects and dyn Keyword Trait objects with the dyn keyword allow for this kind of runtime flexibility.
