Happy to announce TSRX. Think of it as the spiritual successor to JSX. We extracted it from Ripple, and made it framework agnostic. It can compile to React, Ripple and Solid, other frameworks to come soon. tsrx.dev

Facebook's Static Hermes is kind of incredible. It can compile JavaScript into C, which is then optimized into native machine code. I just compiled the Less.js source code into a C library. Then I called it from Rust as a native Parcel plugin (no Node). Wild. 👨🔬 devongovett.me/blog/static-...
How to compile JavaScript to C with Static Hermes
Lately, I've been working on porting more of Parcel to Rust, and investigating ways to embed JS-based plugins. This post describes how I used Static Hermes to compile Less.js to a native C library tha...

pnpm v10.16.0 adds "minimumReleaseAge", a setting for defining how long a version has to have been published before pnpm will install it. A nice countermeasure against accidental installs of short-lived compromised packages before they get taken down. Not a 100% fix, but a great additional step!

TypeScript excitement 😉 TS 6.0 is planning a bunch of breaking changes to tsconfig options to deprecate some and change the defaults for others. This will simplify configuration and ease the transition to the Go-based TS 7.0 👍 The latest pitch is to enable strict type-checking modes by default 🎉
Daniel Rosenwasser@danr.bsky.social · last yr.Just filed an issue to turn `--strict` on by default in TypeScript. Maybe it's a little bit ambitious, but I'm excited for us to try this one. 😄 github.com/microsoft/Ty...

Node excitement 😉 Congrats to @marcoippolito.dev on today's landmark Node 22.18 release. It is the first LTS release to ship unflagged TypeScript support 🎉 This means Node can run *.ts files. It pairs well with TypeScript's "erasableSyntaxOnly" flag 👍 Many folk contributed 🙏
Marco Ippolito@marcoippolito.dev · last yr.Type stripping is enabled by default 🔥🔥🔥🔥 You can just run `node file.ts` without `--experimental-strip-types` flag. This is a huge milestone
