Welcome to My Golang Study Note

This repository is a collection of my notes and examples while learning Go & its support libraries. It covers various technical stacks, such as configuration, logging, messaging, ORM, route, etc. I create one workspace each tech stack, each tech stack covers several different library implementation modules. For example, logging workspace contains three different libraries, such as uber/zap, zerolog, and slog. The examples are designed to be simple and easy to understand, focusing on the core concepts of each topic. The code is written in a modular way, allowing you to run each example independently.
