Atmosphere vs NestJS: What are the differences?
Atmosphere: Realtime Client Server Framework for the JVM, supporting WebSockets and Cross-Browser Fallbacks Support. The Atmosphere Framework contains client and server side components for building Asynchronous Web Applications. The majority of popular frameworks are either supporting Atmosphere or supported natively by the framework. The Atmosphere Framework supports all major Browsers and Servers; 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..
Atmosphere and NestJS can be primarily classified as "Frameworks (Full Stack)" tools.
"Cross-Browse" is the primary reason why developers consider Atmosphere over the competitors, whereas "Powerful but super friendly to work with" was stated as the key factor in picking NestJS.
Atmosphere and NestJS are both open source tools. It seems that NestJS with 17.4K GitHub stars and 1.22K forks on GitHub has more adoption than Atmosphere with 3.34K GitHub stars and 720 GitHub forks.
