Oh my, yes! We have some legacy microservices written in Swift/Vapor (while our main stack is NestJS) and instead of rewriting them to TypeScript, we can use this. Cool!
Actually, we are using Node/Nest from the start. A significant amount of our business logic was written in Swift for our iOS mobile app, which we eventually moved to the microservices (Vapor). This was because we needed to create an Android app and didn't want to write new code from scratch.
