I just started a project in NestJS. Prior to this I was working on express for NodeJS backend where I had to do a lot of manual stuff and achieving dependency injection across the application was a pain. I'm impressed with NestJS so far. If I could go back in time and re-work the project, I'd choose NestJS. I've also worked with Rails and Spring boot. With NestJS I get the same ease and flexibility like in Rails and Spring boot.

Finally a great web application framework for NodeJS.
