Go-mapper – AutoMapper-style struct mapping for Go
I’ve worked a lot with C# and .NET, and one tool I really missed when using Go was AutoMapper. So I built go-mapper, a lightweight Go package that helps map between structs — useful for converting DTOs to domain models, etc. Uses Go generics (1.18+) Supports shallow copy of fields Custom field transformations with fluent API Optional interface for struct-level control Example: type CreateUserDto struct { Name string Password string } type User struct { Name string PasswordHash string } mapper.CreateProfile(CreateUserDto{}, User{}, mapper.ForMember(func(u *User) any { return &u.PasswordHash…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https://jameshard.ing/pilot/globes/all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
