Marble.js VS Nest

I found marblejs which makes use of rxjs and FP-TS, but "I'm not feeling it", so I'm looking for alternatives.

Marble.js is a functional reactive Node.js framework for building server-side applications. It’s based on TypeScript and RxJS and relies on the reactive paradigm, with functional sugar on top of the Node platform.

I had never heard of this before so I found the github. It has a lot of stars, but that doesnt mean much, so I checked out the packages on NPM. Marblejs/core has about 630 downloads in the past week. Thats not dead, but its not enough that youll find random redditors with production experience with it.

In this article, we will walk through a step-by-step process to secure a Nest.js RESTful API using Keycloak. This includes setting up an application client and configuring authentication and RBAC for your API endpoints.

The rapid evolution of web development in 2025 makes it imperative to choose a framework that truly fits your project. Whether this involves a dynamic web application, scalable API, or high-performance SaaS product, the decision to select Next.js or Nest.js becomes all the more key. While both do their thing really well, in this sense, they don't do the same thing.

Ok, you're right.

I was referring to the usual ones (Next, Nuxt, SvelteKit, Remix, etc).

Joytick looks cool. Besides this there's also NestJS

In Action: A NestJS Example

But what ultimately made me disillusioned was encountering bugs and odd behavior over time. For instance, I have a directory called ./test/helpers which contains helper modules for my tests. This is a convention I learned from Nest tests during my time at Procore. Tap absolutely refused to ignore this directory (which had no tests in it), regardless of my efforts to configure it thusly.

We need to start with a base application, let's say a nestjs application, with vertical slice architecture, where our application is mainly composed by: controller, service and a repository.
