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.

Mariposa – A programming language with time-travel
You don't necessarily need to embed it into the programming language itself to get a ton of value. XTDB (https://github.com/xtdb/xtdb) offer a Clojure, Java and HTTP API for interacting with the database, which is bitemporal and lets you query the database for a specific point in time for example.

I made a basic python client and ORM for XTDB
XTDB is a bitemporal and dynamic relational database for SQL and Datalog, written in Clojure. The Python application I work on uses XTDB for its bitemporal and schema-less nature. There were a few Python clients that looked unmaintained and lacked some features we needed, so I tried to build something that would have fit our own requirements in hindsight. This includes:
-
Endatabas: A SQLite-inspired, SQL document database with full history
it's bitemporal, will be SQL-compatible, and also has another query-language - XTQL :

Is Datomic right for my use case?
You can also consider other durable Datalog options like datahike or datalevin which can work either as lib (SQLite style) or in a client-server setup; if you want to play with bi-temporality XTDB is a rock solid option with very good support and documentation.

Datomic Is Now Free

Taming the Time: how to install & develop with XTDB
XTDB, or Cross-Time Database, is a distributed and transactional database system designed to handle complex and changing data with ease. It is based on a bitemporal model, which allows for the tracking of both the valid time and transaction time of data, enabling powerful and flexible querying capabilities. With XTDB, developers can work with immutable data structures, which simplifies development and improves reliability. Its graph query language, Datalog, provides a powerful and expressive way to navigate relationships within the data.

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.)
