DDoS'ing the human brain AI made us mass produce code at a scale we never could before. More code, more problems, same brain. Somehow I'm more productive and more exhausted at the same time.

Some recent Rspack benchmark trends.

Rspack 2.0 work is helping improve performance steadily⚡️

Announcing TypeScript 6.0 - TypeScript TypeScript 6.0 is now available! TypeScript 6 is a stepping-stone release, aligning with the upcoming native-speed 7.0 release.

TypeScript 6.0 is now available!

This release brings better type-checking for methods, new standard library features, new module features for Node.js, and more!

But most important, this release brings us one step closer to the upcoming native-speed 7.0!

new post on my personal blog.

i think these three areas often go unexplained, so hopefully this explains why some of these packages exist. these are fine to exist but the majority of developers shouldn't have to pay the cost for them.

Directed Acyclic Graph (DAG) showing connections between JavaScript files, with one file selected and its incoming and outgoing dependencies highlighted.

Recently added a connection diagram view to Sonda 👀

It complements the treemap view and makes it much easier to see how bundles and source files connect.

Also, you can now upload JSON reports and get an instant HTML report: sonda.dev/demo

Happy Monday CSS gang. Let's improve CSS minifiers!

Here's a suite of 350 minifier tests I've written that show there's lots of opportunities for minifiers to do better: www.keithcirkel.co.uk/css-minify-t...

I know you all can help add 350 more, so come contribute! github.com/keithamus/cs...

🙋‍♂️ I _could not be more thrilled_

this isn't a zero-sum game

we're here to make the web better for everyone, and this is a win 🔥

props to @npmjs.bsky.social 🙏

The following new buttons were added to the package details page on npmjs.org: “Analyze security,” “Check bundle size,” “View package health,” and “Explore dependencies.”

Well, well, well... look who suddenly remembered they can ship new features. Right after the community started working on an alternative. What a coincidence! 🙃

We’ve already tested how AI can help with the migration, and the results are VERY promising. Vitest’s popularity and API similarity to other runners helps a lot.

We’ll likely be able to automate the vast majority of the migration and only manually handle the tricky parts.

We’ve been very happy users of Vitest’s Browser Mode since it was introduced. Soon, we’ll be migrating our largest codebases (~35k tests) from Karma to Vitest.

Not exaggerating when I say that we can’t wait to get started 😅

a GitHub PR titled `fix(adobe): handle provider configuration objects properly` with the following text: 🐛 Bug Fix Potentially fixes Adobe font-face declaration generation regression introduced in v0.12.1. Closes #736 ⚠️ Note: This fix was developed with AI assistance This PR was blindly developed by AI, without me having deep any knowledge of @nuxt/fonts internals. While it's (claimed by Claude to) been tested and appears (again, according to Claude) to work correctly, a thorough review by @danielroe or someone familiar with the fontless/unifont architecture would be appreciated.

I actually love this disclaimer

The glob library on npm currently has a CVE. It's entirely predictable since it has 26 dependencies.

If you're getting a security warning from glob it's a good time to see if you can switch to a lighter dependency such as tinyglobby or Node's built-in glob functionality: nodejs.org/api/fs.html#...

tinyglobby: a success story in modernization and performance The story of tinyglobby, one of the e18e community's most successful projects

tinyglobby is a great success, and has shown us how much we can improve perf for everyone. here's some of the story!

big thanks to @superchupu.dev and @benmccann.com for putting so much work into this and the migrations/adoption. we're lucky to have both in the @e18e.dev community 💙

View transitions are in every browser now ✨

second: devs tend to fixate on repetitiveness as a sign of poor code quality. but the cure is often worse than the disease, because if unchecked it leads to the thing that, in my experience, really _is_ a sign of poor code quality: indirection. when you're writing code, indirection is your nemesis.

some thoughts about the bloat introduced by edge-case first libraries

Great benchmark! We're continuously optimizing Rspack for faster builds and smaller bundle sizes.

It's worth noting that webpack/Rspack produce larger bundles in this case due to different handling of dynamic require() in moment.js, see github.com/filipsobol/b...
