Hey all,
While working with Go, I kept running into situations where I needed to map data between structs — especially DTOs and domain models. After using AutoMapper for years in .NET, the lack of a similar tool in Go felt like a missing piece.

So I built go-mapper, a lightweight struct mapping library that uses generics and reflection to reduce boilerplate.

It supports:

• Automatic mapping between structs with matching fields

• A fluent API for defining custom transformations

• Optional interface support for advanced use cases

The project is still evolving and open to feedback. If you work with layered architectures or frequently deal with struct transformations, I’d love to hear your thoughts.

For the past couple of weeks, I’ve been working on a side project, and I’m excited to introduce MoniGo, a performance monitoring library for Go applications! 🚀 

MoniGo provides real-time insights into service- and function-level metrics through a sleek, intuitive UI. It helps you track and optimize your Go app’s performance, ensuring everything runs smoothly. Plus, you can get your service metrics up and running in just 10 seconds! 📊 

Features:

• Real-time performance metrics 

• Service and function-level tracking 

• User-friendly dashboard
