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.

Let's write a simple microservice in Clojure
Compojure's DSL for web applications makes it easy to set up REST API routes with corresponding HTTP methods. Adding a Swagger API descriptor through libraries like ring-swagger provides a visual interface for interacting with the API and enables client code generation. You can use the Prismatic schema library for HTTP request validation and data coercing to ensure the API consumes and produces data that conforms to predefined schemas. Compojure's middleware approach allows for modular and reusable components that can handle cross-cutting concerns like authentication, logging, and request/response transformations, enhancing the API's scalability and maintainability.

What are some great Clojure libraries, as of 2021?
The widespread use of simple data structures for almost everything makes graph data - and any data really - very, very portable and it helps to enable this emerging ecosystem of graph libraries in both the frontend and backend.

Tired by the dynamicism
Plumatic schema (https://github.com/plumatic/schema) , or friends I might be wrong, but I think schema might make more sense to you coming from the F# world (might be wrong)

Clojure from a Schemer's perspective
This one? I didn't. I hear good things about it, and it's reached a point of maturity, being widely used in production.

Worrying comment from HN on Building a Startup on Clojure
Uhhh spec has existed for a long time and before that, schema Nowadays we also have the excellent malli. If his codebase is full of functions where the shape of the data isn’t obvious, isn’t documented and isn’t specified in a specific/schema, that’s on him and his bad coding practices and really no different from passing data in other dynamic languages. A class by itself (without additional effort) only gives you field names.

Building a Startup on Clojure
I don't understand this reputation either. There are very large systems built on other Lisps. For example, Emacs has a massive amount of Elisp. Elisp is much more primitive than Clojure, and traditionally libraries don't use e.g. data schemas [1] as runtime contracts for data.
Obviously, once a system built on top of a dynamic language grows beyond certain threshold, you need to be very disciplined as there are no static types to ensure some degree of correctness.

General anxiety regarding learning Clojure and such
Try to learn a schema library early, like Malli or Prismatic Schema. Do not mistook them as "static-typing" things - it's more for data validation and coercion than "security that things will get the right typing information". The idea to learn them early is how you'll shape future code: validating all "output data" first, them using that data inside your program without "defensive programming" like checking every time if a specific value on a map is nil, etc

What are some great Clojure libraries, as of 2021?
In Clojure, declarative data specifications for validation and generation are also very mainstream. Schema was first out the door, Clojure Spec is the most popular library, while malli is gaining popularity fast at the moment.
What are some alternatives?
malli - High-performance data-driven data specification library for Clojure/Script.
xforms - Extra transducers and reducing fns for Clojure(script)
clj-kondo - Static analyzer and linter for Clojure code that sparks joy
specter - Clojure(Script)'s missing piece
clojure-graph-resources - A curated list of Clojure resources for dealing with graph-like data.
matcher-combinators - Library for creating matcher combinator to compare nested data structures
meander - Tools for transparent data transformation
fulcro - A library for development of single-page full-stack web applications in clj/cljs
coalton - Coalton is an efficient, statically typed functional programming language that supercharges Common Lisp.
