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.

Datalog in 100 lines of JavaScript (2022)
Hi pests, I don't think the criticism in the comments gives a full picture.
I wrote about a particular flavor of datalog, in common use today. [1] [2]. The earliest representation I know, which matches the syntax of my essay, was in SICP [3]
There's another, more academic form of datalog, which looks a lot more like prolog. Both have lots of similarities: both systems have a set of facts and rules. Both systems have can take a partially filled fact or rule, and find all matching facts. The more academic flavors of Datalog are useful for general logic, and particularly powerful for recursive questions. The variant I showed is more tailed for database queries.

This look nice !
Datascript seems to be another Datalog engine (in memory only)

Working with large maps
An in-memory database like Datascript may be worth looking into. Otherwise you could take an indexing approach: put all the data into one big map indexed by some unique key, and have a bunch of supplementary indexes that are updated on insertion.

Why Is Jepsen Written in Clojure?
I am not sure what a web framework is, to be honest. The choices for many parts of a web application are really domain-specific and I'm not sure a single "framework" would work for everyone.
As far as web-related components go, my app uses Rum (as an interface to React), ring, http-kit, pushy (for history manipulation), sente (for websockets), buddy (for authentication tools).
If you are looking for a batteries-included "I want to have some sort of webapp right away" thing, I think https://kit-clj.github.io would fit the bill, but the general feeling in the Clojure community is that unlike Python with Django or Ruby with Rails, the choice of app components is not predetermined by the language.

Most commonly used libraries/frameworks in Clojure
Luminus has, in theory, been superseded by Kit: https://kit-clj.github.io/ but even so it is still "an opinionated bundle of libraries" rather than a framework.

Is there an open source project focused on ClojureScript, React, Reagent?
I learned by using https://luminusweb.com/docs/clojurescript.html to get me started. It gives you a plethora of sane starting points, and you can just work on switching it to your own business logic. Troubleshooting and adding functionality will usually lead you to understand how things work. The authors of luminus have moved on to build kit: https://kit-clj.github.io/ which is probably another good starting point.

Clojure Turns 15 panel discussion video
The cljs stack I hear about a lot (and use) is ShadowCLJS with reagent (https://reagent-project.github.io/) and re-frame (https://day8.github.io/re-frame/). ShadowCLJS is more of a build tool, but is really well documented and easy to use. Reagent is basically react but a simpler API, and re-frame is a layer on top of that provides data subscriptions and event-handlers to manage app state. It's overkill for some apps but I find it's actually super easy to work with and not as much complexity as I thought.
For backend there is luminus (https://luminusweb.com/) or Kit (https://kit-clj.github.io/). They are basically project templates that wire together a ton of popular solutions for various things - database access, migrations, security, html templating, etc. Also includes frontend frameworks like re-frame if you want.

your thoughts on the kit framework?
The component itself is just a thin wrapper for conman, you can see it here.

Ask HN: Share Your Personal Site
Here’s me: https://luciano.laratel.li/
I was happy I could get the domain! Pretty simple hand-rolled server-rendered site using the kit-clj[0] and neat-css[1]. Main backbone of the site is here[2]. I used to use a CLJS SPA but it was overkill and not as nice to use (load times particularly.)
