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.

Rich Hickey – open-source is Not About You
If you're not familiar with lisps in general, it might be hard to grok the differences between lisp-macros (as used in Clojure) and "normal" macros you see in other languages.
But, if you are familiar already, and just wanna see examples of neat macros that makes the API nicer than what a function could provide, here are a few:

A History of Clojure (2020) [pdf]
* HTTP: Ring is the de facto way to manage HTTP request (see https://github.com/ring-clojure/ring/wiki/Concepts). Jetty and Aleph are common web servers (and https://github.com/clj-commons/aleph) that implement Ring interface.

what componies uses Clojure, and what componies deceased the use of other languages after additions of Clojure, for example Dropbox decrease the use of python after addition of Go programming language, are there any similar story with Clojure?

I Don’t Like Go’s Default HTTP Handlers
> In the HTTP handlers it makes sense that you don't have return values, because: What would you do with that value exactly?
I think that approach used by clojure's ring shows an elegant way to represent http responses https://github.com/ring-clojure/ring/wiki/Concepts#responses. They are essentially structs with the following fields:
status := number
headers := map of string->string
body := stream | string | seq | inputstream
Request handlers are handed a request struct that is similar. The handler is a function that maps a request to a response (it doesn't actually write to streams itself).
I like this style for an http library for a couple of reasons:
1. HTTP resources can be viewed as functions whose domain is the request, and range is the response. Having the abstraction match that makes for really nice code.

what web framework do you use?
While you won't find your Spring here, you will find that many of those web libraries will tend to use or produce Hiccup, return Ring maps or maybe have pipelines built using interceptors. Composing libraries together is usually not that hard, but it does require you to leave the comfort zone of the framework's abstractions to try to understand what is actually happening e.g. when someone makes an HTTP request and something is returned and displayed in the browser.

Microhttp is an event-driven, single-threaded, zero-dependency web server with 500 LOC. Benchmarks on EC2 show 100,000+ requests per second and 50,000+ persistent connections.
On that note, are you able to support everything required by the ring spec?

is bulding rest apis with clojure a good idea ?
You can check out my example project in Clojure with using Ring.

Can someone help me understand ring's async handlers (specifically, with Jetty)
I've tried to pair down to the simplest example which shows the issue, and raised it here as I couldn't see one you'd already created or similar: https://github.com/ring-clojure/ring/issues/436 This is so that I have something to link to/follow from our side, hope you don't mind, and many thanks for the diagnosis!
