Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What is scala's modern Web API framework?
I'm also working on improving our template to provide a better developer experience (https://github.com/wiringbits/scala-webapp-template/issues/307).

Screencast for creating a simple stream-powered background job processor in Scala
Ticket: https://github.com/wiringbits/scala-webapp-template/issues/294
-
Tooling: Vercel-like preview environments got into the Scala Webapp Template
After thinking for a bit, I got to the conclusion that Vercel's preview environments are not really hard to implement. Then, I put my hands into this and created an integration for one of our projects: https://github.com/wiringbits/scala-webapp-template/pull/299
-
Is there anyone here working as Scala Front end developer ?
You can also check out our template which uses Scala.js + Slinky + Mui.
-
Lightweight background job runner framework?
https://github.com/wiringbits/scala-webapp-template does something very similar with akka-stream but it is tied to send emails on the background, it seems that we can easily extend it to support arbitrary jobs (https://github.com/wiringbits/scala-webapp-template/issues/294). What is not so simple to do with such a schema is to distribute the jobs in many servers.

Scala hosting services with free tier
Given this, I wonder if you have ever worked with Ansible, if so, you could pick these playbooks to deploy to a ubuntu server, these playbooks are pretty generic for Scala apps, you will need to update the build/run script, everything else is already handled (like uploading the app to a server, creating users, registering a systemd service, etc).

Hosting a scala play website?
Years ago, I wrote some ansible scripts so that ansible-playbook -i test-hosts.ini server.yml is enough to deploy the app (sample).

Given that you aren't familiar with Scala, I'd suggest looking into Play Framework, if you want to start fast and play with a project, check this template, your js background could help you to update the frontend relatively quick.

Hosting Options for Scala CRUD App
I'd suggest to check this template which already has an skeleton for a CRUD app, including deployment scripts that can mount an environment in ubuntu servers.

what library/framework should I use for backend development?
You're not confined to the usual suggestions below (play, http4s). There's a ton of options. (I wrote test cases using a bunch of different frameworks a few years ago at https://github.com/hohonuuli/msdemos). Having written services using a variety of frameworks in production, I would strongly suggest using one that auto-generates API docs (openapi, swagger) for you. That will save you a huge amount of time later on. For heavier services, like the one at https://fathomnet.org/, I tend to the Java side (Quarkus is my current top choice, but Micronaut and Helidon are both great). For everything else I use Scala. My go-to right now is tapir using a vertx backend. See https://tapir.softwaremill.com/
-
Micronaut vs others(Spring Boot, Quarkus and co.)
Tapir is a Scala framework. (which runs on the JDK) Since the recent release of version 1.0, it's become my go to for many projects. It doens't provide much in the way of integrations with 3rd party frameworks, but I actually prefer that. It does autogenerate great swagger docs though.

Programming language comparison by reimplementing the same transit data app
I do wonder where the recommendation to use http4s for beginners came from. http4s is a very capable library (and if you care much about composition it is excellent), but I wouldn't describe the documentation as beginner friendly.
A slightly better starting point for scala 3 + type-safe server building is tapir e.g. https://github.com/softwaremill/tapir/blob/master/examples3/... . With that, you get a declarative definition of your endpoints (+ error types, auth, etc.) that you can use for both servers and clients, which comes very handy when writing integration tests of course.
> absolutely ridiculous the fetishization of extremely complex FP and type-level hacking that goes on in the ecosystem
An alternative way to look at it is that there is a lot of essential domain complexity that gets encoded via the type system to let the compiler do the hard work. That "extremely complex FP" does not arrive out of nowhere - I really recommend at least skimming through the slides from rossabaker, the http4s designer, that motivate where the core type signature comes from https://rossabaker.github.io/boston-http4s/#2
I suppose one of the "features" that I like about the (typelevel) community is that the approach of "worse is better" is not taken, and a lot of effort is expended to make things correct, modular and orthogonal. This has the drawback of increased upfront complexity, that anecdotally pays off the moment your compiler does not error and the program runs as intended.

Scala.js AWS Lambda, using Scala 3
Did you try tapir? There is a module for deploying aws lambda with Scala js. Not sure whether it is compatible with Scala 3, I am sticking with Scala 2 until Scala 3 gets more mature.
-
Library recommendations?
I'm aware, but it's a design decision that was made on purpose, and which I find in practice not a big problem at all.

Monorepo: seeking for an advice for bi-lang project
Backend is source of truth for types on frontend (backend generated OpenAPI definition with tapir, frontend takes it with orval)
-
Experienced dev new to Scala looking for a quick answer to get me on the right track - Advice on *standard* Scala framework stack to quickly set up a web-app backend ;
In all cases I would strongly suggest to have a look at Tapir, regardless of the server implementation that you pick.

-
Scala vs Kotlin for REST API
Tapir is awesome, and you can pick the server backend according to your preferred ecosystem (for instance http4s + doobie, Zio + Quill, Akka + Slick, ...)
-
Resources for learning about http4s and Typelevel ecosystem?
Finally I would strongly recommend having a look at Tapir. Even if you don't need to share endpoints or generate OpenAPI documentation, it provides a really neat abstraction on top of http4s.
