Grails vs NestJS: What are the differences?
Developers describe Grails as "An Open Source, full stack, web application framework for the JVM". Grails is a framework used to build web applications with the Groovy programming language. The core framework is very extensible and there are numerous plugins available that provide easy integration of add-on features. On the other hand, NestJS is detailed as "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..
Grails and NestJS belong to "Frameworks (Full Stack)" category of the tech stack.
"Groovy" is the top reason why over 44 developers like Grails, while over 7 developers mention "Powerful but super friendly to work with" as the leading cause for choosing NestJS.
Grails and NestJS are both open source tools. NestJS with 17.4K GitHub stars and 1.22K forks on GitHub appears to be more popular than Grails with 2.48K GitHub stars and 945 GitHub forks.
According to the StackShare community, Grails has a broader approval, being mentioned in 47 company stacks & 22 developers stacks; compared to NestJS, which is listed in 12 company stacks and 13 developer stacks.
