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.

A technical tale of NodeSecure - Chapter 2
I discovered the package estree-walker from Rich Harris which was compatible with the EStree spec. Combined with the meriyah package this allows me to convert a JavaScript source into an ESTree compliant AST.

Storybook 8 Beta
First, we switched the default compiler for new projects from Babel to SWC (Speedy Web Compiler). SWC is dramatically faster than Babel and requires zero configuration. We’ll continue to support Babel in any project currently using it.

Implementing auth flow as fast as possible using NestJS
As the reference explains “**SWC** (Speedy Web Compiler) is an extensible Rust-based platform that can be used for both compilation and bundling. Using SWC with Nest CLI is a great and simple way to significantly speed up your development process.”

Ruby Outperforms C: Breaking the Catch-22
This is specifically about breaking the myth that performing expensive self-contained operations (e.g, parsing GraphQL) in a native extension (C, Rust, etc.) is always faster than the interpreted language.
The JS ecosystem has the same problem, people think rewriting everything in Rust will be a magic fix. In practice, there's always the problem highlighted in the post (transitioning is expensive, causes optimization bailouts), as well as the cost of actually getting the results back into Node-land. This is why SWC abandoned the JS API for writing plugins - constantly bouncing back and forth while traversing AST nodes was even slower than Babel (e.g https://github.com/swc-project/swc/issues/1392#issuecomment-...)

Show HN: Ezno, a TypeScript checker written in Rust, is now open source
Very cool! I'm curious, is this intended for dev tooling?
For example, I could see this (or something similar) being useful as the engine for a typescript language server that would be faster than the standard one
But if it's not aimed at 1:1 with tsc, would it be intended more for something like swc[1]?
Or what would you expect people to use this for, besides just being a cool project to learn from?

TypeScript team released an explorer for performance tuning
This is... good news, but I still cannot fathom using the default Typescript compiler for regular development. Seriously, leave the type-checking to your IDE and CICD chain, and switch to using tsx (https://www.npmjs.com/package/tsx) or swc (https://swc.rs/) and you will _immediately_ notice the difference in speed and productivity.
