NestJS vs Trailblazer: 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, Trailblazer is detailed as "A new architecture for Rails". Trailblazer is a thin layer on top of Rails. It gently enforces encapsulation, an intuitive code structure and gives you an object-oriented architecture. In a nutshell: Trailblazer makes you write logicless models that purely act as data objects, don't contain callbacks, nested attributes, validations or domain logic. It removes bulky controllers and strong_parameters by supplying additional layers to hold that code and completely replaces helpers.
NestJS and Trailblazer can be categorized as "Frameworks (Full Stack)" tools.
"Powerful but super friendly to work with" is the primary reason why developers consider NestJS over the competitors, whereas "Trailblazer allows creating sane, large apps in Rails" was stated as the key factor in picking Trailblazer.
NestJS and Trailblazer are both open source tools. NestJS with 17.4K GitHub stars and 1.22K forks on GitHub appears to be more popular than Trailblazer with 2.91K GitHub stars and 129 GitHub forks.
