   Project mention: Introducing My New Project Tarin, A TypeScript Backend Library For API Development | dev.to | 2025-03-09

   While working on a full-stack project, I built both the frontend and backend API myself. The problem? Manually documenting the API was tedious and time-consuming. So, I started looking for a self-documenting API library for Node.js on Google and npm—but surprisingly, I couldn’t find one. I did come across Tapir, a great project for Scala, but I needed something similar for TypeScript. Since nothing existed, I decided to build my own—and that’s how this project began.
