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.
spec-tools
- Which type declaration library is the standard nowadays?
-
More concise spec definitions
I'd like to use a syntax like how ::input-correlations-concise is defined, but am having trouble debugging the spec-tools.data-spec error ("Unable to resolve spec: :app.specs/input-correlations-concise") after setting it up with these instructions. I also want to make sure I'm doing things the "right" way.

Python dataclass equivalent
I like spec-tools data specs. I never got into schema, although I was aware of it. spec came along and swept a substantial portion of the crowd (I think the interleaving of parsing and regex style operators is slick/useful). Malli looks excellent though, and I think it's worthy of learning. I have no opinion on spec2 as of yet.

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.

XTDB on Mobile Possible?
There is also datascript as a similar option.

wotbrew/relic: FRP for Clojure(Script)
What's the use case for relic? Sounds similar to https://github.com/tonsky/datascript ?

Show HN: Cozo – new Graph DB with Datalog, embedded like SQLite, written in Rust
This look nice !
Datascript seems to be another Datalog engine (in memory only)

Ergonomic inline SQL as a Python library
Inspired by past work: LINQ, inline-python, crepe, DataScript, Riffle.

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.
What are some alternatives?
truss - Assertions micro-library for Clojure/Script
asami - A graph store for Clojure and ClojureScript
scope-capture - Project your Clojure(Script) REPL into the same context as your code when it ran
datahike - A durable Datalog implementation adaptable for distribution.
malli - High-performance data-driven data specification library for Clojure/Script.
datalevin - A simple, fast and versatile Datalog database
ghostwheel - Hassle-free inline clojure.spec with semi-automatic generative testing and side effect detection
10000-markdown-files - 10,000 markdown files. Useful for stress testing note-taking tools.
snoop - Function instrumentation using Malli schemas.
xtdb - An immutable database for application development and time-travel data compliance, with SQL and XTQL. Developed by @juxt
defn-spec - Add function args and return Spec checking via assertions
Apache AGE - Graph database optimized for fast analysis and real-time data processing. It is provided as an extension to PostgreSQL. [Moved to: https://github.com/apache/age]
