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.

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-...)

FTA: Fast TypeScript Analyzer
FTA is a TypeScript static analysis tool built on the speedy foundations of swc. FTA is fast; capable of analyzing more than 150 files per second on typical hardware, it offers a powerful addition to your code quality toolkit.

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?

[AskJS] Advantages of Rollup over other bundlers for creating libraries?
Rollup is highly configurable via plugins. It also supports a wide range of transpilation targets. However, it's written in JavaScript (well, TypeScript) so there's a ceiling on how fast it can go. esbuild and swc are orders-of-magnitude faster than Rollup.

Optimize your Bundle Size with SWC and GraphQL Codegen
There was already a Babel plugin for the client-preset for projects using Babel in the client-preset package. Now, as SWC itself, and Next.js is becoming more popular and uses SWC as its default compiler, there was a need for a SWC plugin as well. SWC is a fast and modern JavaScript/TypeScript compiler written in Rust, so the Babel plugin couldn't be used.

TypeScript Might Not Be Your God: Case Study of Migration from TS to JSDoc
The most well-known tools that rely on JSDoc are Closure Compiler (not to be confused with the Closure programming language) and TypeScript. Both of these tools can help make your JavaScript typed, but they approach it differently. Closure Compiler primarily focuses on enhancing your .js files by adding typing through JSDoc annotations (after all, they are just comments), while TypeScript is designed for .ts files, introducing its own well-known TypeScript constructs such as type, interface, enum, namespace, and so on.

Svelte is migrating from TypeScript to JSDoc
10 years ago I have used Closure compiler from Google, https://github.com/google/closure-compiler/wiki/Annotating-T... , as a type checker. We had to use for production a different minimizer, not the closure compiler, but it was extremely useful to check for types and JSDoc-style annotations were very readable with minimal distraction.
Flow for JS from Facebook also supports types-as-comments, https://flow.org/en/docs/types/comments/ , but those are rather ugly as one has to intermix them with JS rather than using separated comment block on top.

Do any engines or optimizers product TS-specific performance gains?
I think only Google Closure Compiler did some optimizations based on its JSDoc-style annotations (see docs). If I remember correctly, types mostly allowed renaming objects' properties across modules, but most other advanced optimizations (like dead code elimination or functions inlining) didn't rely on types. In my experience properties renaming resulted in subtle, hard to discover bugs and I'd say they didn't bring much benefit.
