Ask HN: Nestjs 2021, what do you guys think?

Enterprise and startups are mostly using C# and Java. Some are using python (DRF) for their core, however Node are mostly used for small services and not as a main choice. With the latest post about Remix (and all stuff that has been happening in JS/TS world), I think Nestjs is also a solid choice on building scalable applications as a core of a startup. For the past few years it has been gaining tractions and many sponsors, going to the right direction as well. Has anyone ever used NestJS for their side project that went off? What are the challenges that you get? I'm trying it out for my next project
