This is the most impressive project in Nim I’ve seen yet. Rewriting any major front-end, complete with working authentication and handling idiosyncrasies of the private API is a herculean task. For context, Twitter would have a team of two dozen or more supporting what this does, effectively. Kudos to the author for accomplishing this feat!
The frontend uses Karax, which is my favorite frontend/SPA library in any language. It is an absolute joy to use, even if it's a bit rough around the edges.
