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.

SQLite JavaScript: Extend your database with JavaScript
This is a fantastic approach.
BTW, it looks like the js engine is "QuickJS" [0]. (I'm not familiar with it myself.)
I like it because sqlite by itself lacks a host language. (e.g., Oracle's plsql, Postgreses pgplsql, Sqlserver's t-sql, etc). That is: code that runs on compute that is local to your storage.
That's a nice flexible design -- you can choose whatever language you want. But quite typically you have to bring one, and there are various complications to that.
It's quite powerful, BTW, to have the app-level code that acts on the app data live with the data. You can present cohesive app-level abstraction to the client (some examples people will hopefully recognize: applyResetCode(theCode) or authenticateSessionToken(), or whatever), which can be refined/changed without affecting clients. (Of course you still have to full power and flexibility of SQL and relational data for the parts of your app that need it.)

JSLinux
Considering the extremes of prolific developers gives interesting contrast to dogmas such as "functions/files should never be above x lines", where `quickjs.c` is 50k lines and has functions that are hundreds of lines long:

Building Static HTML Pages with JSX Server-Side Rendering
Built on a highly optimized JavaScript runtime powered by QuickJS, Query offers fast startup times and efficient execution. Its built-in caching mechanism further enhances performance by storing function responses, reducing database load and latency. This focus on speed makes Query a standout choice for server-side rendering, especially in applications with many components.

Introducing our Next-Generation JavaScript SDK
Where the previous SDK was built on top of the QuickJS JavaScript engine and the Javy runtime, the new SDK is built on top of the Firefox browser’s SpiderMonkey engine, and the Bytecode Alliance’s StarlingMonkey runtime and ComponentizeJS WIT bindings generator.
