A couple of years ago, I went to work in SF area and I switched my dev environment for MacOS.
On my free time I love to do some apps and when I started to learn Swift and Cocoa, I got tired of dealing with same things with platform specific complicated stuff.
I decided to build by own GUI tool, written with the Go programming language.
A couple of iteration later (years), it became a WebAssembly library for building progressive web apps.
It is named go-app and you can see how it look like with this dogfooded documentation website: https://go-app.dev
If you like lofi music when working, or you are a fan of World of Warcraft game, there is those 2 others ones built with this package: https://lofimusic.app and https://murlok.io
Hope you find it interesting :)
