NestJS vs Yesod: What are the differences?
What is 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..
What is Yesod? A RESTful Haskell web framework built on WAI. Yesod believes in the philosophy of making the compiler your ally, not your enemy. We use the type system to enforce as much as possible, from generating proper links, to avoiding XSS attacks, to dealing with character encoding issues. In general, if your code compiles, it works. And instead of declaring types everywhere you let the compiler figure them out for you with type inference.
NestJS and Yesod 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, Yesod provides the following key features:
- safety & security guaranteed at compile time
- developer productivity: tools for all your basic web development needs
- raw performance
"Powerful but super friendly to work with" is the top reason why over 7 developers like NestJS, while over 5 developers mention "Haskell" as the leading cause for choosing Yesod.
NestJS and Yesod are both open source tools. NestJS with 17.4K GitHub stars and 1.22K forks on GitHub appears to be more popular than Yesod with 2.11K GitHub stars and 329 GitHub forks.
Sofit Software, Quero Education, and YABAWT are some of the popular companies that use NestJS, whereas Yesod is used by DoxIQ, FP Complete, and SimplyRETS. NestJS has a broader approval, being mentioned in 12 company stacks & 13 developers stacks; compared to Yesod, which is listed in 5 company stacks and 5 developer stacks.
