NestJS vs Mono: What are the differences?
Developers describe NestJS 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.. On the other hand, Mono is detailed as "*Open source implementation of Microsoft's .NET Framework *". It is a software platform designed to allow developers to easily create cross platform applications part of the .NET Foundation. It is an open source implementation of Microsoft's .NET Framework based on the ECMA standards for C# and the Common Language Runtime.
NestJS and Mono can be primarily classified 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, Mono provides the following key features:
- Cross platform
- Open source
- Implementation of Microsoft's .NET Framework
NestJS and Mono are both open source tools. NestJS with 19.6K GitHub stars and 1.46K forks on GitHub appears to be more popular than Mono with 8.19K GitHub stars and 3.28K GitHub forks.
TheIconic, Sofit Software, and Quero Education are some of the popular companies that use NestJS, whereas Mono is used by Croesus Finansoft, KARE Design, and Outsource2india. NestJS has a broader approval, being mentioned in 21 company stacks & 89 developers stacks; compared to Mono, which is listed in 7 company stacks and 4 developer stacks.
