NestJS vs Apache Sling: 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.; Apache Sling: Innovative web framework that is intended to bring back the fun to web development. It is a framework for RESTful web-applications based on an extensible content tree. It maps HTTP request URLs to content resources based on the request's path, extension and selectors. Using convention over configuration, requests are processed by scripts and servlets, dynamically selected based on the current resource. This fosters meaningful URLs and resource driven request processing, while the modular nature of Sling allows for specialized server instances that include only what is needed.
NestJS and Apache Sling can be categorized as "Frameworks (Full Stack)" tools.
Some of the features offered by NestJS are:
- Extensible - Gives you true flexibility by allowing use of any other libraries thanks to modular architecture.
- Versatile - An adaptable ecosystem that is a fully-fledged backbone for all kinds of server-side applications.
- Progressive - Takes advantage of latest JavaScript features, bringing design patterns and mature solutions to node.js world.
On the other hand, Apache Sling provides the following key features:
- REST based web framework
- Content-driven, using a JCR content repository
- Powered by OSGi
