NestJS vs ServiceStack: What are the differences?
NestJS: A progressive Node.js framework for building efficient and scalable server-side applications by @kammysliwiec. Nest is a framework for building efficient, scalable Node.js server-side applications. It uses progressive JavaScript, is built with TypeScript (preserves compatibility with pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming)
Under the hood, Nest makes use of Express, but also, provides compatibility with a wide range of other libraries, like e.g. Fastify, allowing for easy use of the myriad third-party plugins which are available.; ServiceStack: *A configuration free, code-first, light-weight framework *. It is a configuration free, code-first, light-weight framework built on top of ASP.NET for building services and web applications. As the name suggests, it is a stack of services. It provides with just everything that one needs for building end-to-end web services.
NestJS and ServiceStack can be primarily classified as "Frameworks (Full Stack)" tools.
