After many years, I'm heading back to the stage to discuss my experience in measuring Design Systems. I'll share the spotlight with @NoriSte, one of the best developers I've ever worked with!

#jsday #jsday25 #JavaScript

[Matteo Ronchi @cef62]

That's a treasure trove for anyone working on a design system! I'm proud of what they are doing!

[Stefano Magni @NoriSte]

New blog post! 📢 Why and how do we (@PreplyCom) measure the impact of the Design System? 📈

The visual coverage allows us to measure how the Design System impacts our users on the web and mobile

Spoiler: We do it in production and on users' devices.

Keep up the good work! We appreciate the effort and quality you put in the TS documentation

[Andrew Branch @atcb]

Since February, I’ve been spending part of my time rewriting TypeScript’s modules documentation, replacing years-outdated content and adding some that’s never been written down. There’s always more to write, but I’m publishing it officially today. 1/5 https://t.co/mtM1Z1TfBj

[Matteo Ronchi @cef62]

This is so important! So many projects have too many index files. I'm responsible for doing it too 😅

[Marvin Hagemeister ⚛️ @marvinhagemeist]

New post: The barrel file debacle 🪂

How innocent looking code makes your tools slow, often by as much as 60-80%. Test runners and many import cycle detection tools are most affected by this.

[Matteo Ronchi @cef62]

That's smooth! Looking forward to using it!

[Nauman Umar @nmanumr]

Just tried out the View Transition API for micro-interactions on the login page of @hirecinch – it's a game-changer for micro-interactions! Super easy to use, and the best part? adds 0 bytes to the bundle. Excited to explore its potential at the views level too.

[Stefano Magni @NoriSte]

I just published how I implemented a Production-grade gradient-bordered, semi-transparent, rounded button 😊
It's different from the high-level, senior-oriented articles I usually write... But I wanted to help the next ones that have to do the same 😁

I highly recommend Stefano! If you're looking for a smart and experienced frontend dev, you have found it! I still miss working with him.

[Stefano Magni @NoriSte]

I'm officially looking for a new gig 😊

Let me introduce myself: I'm Stefano Magni, a Senior Front-end Engineer, an expert with React and TypeScript (also on big codebases), and proficient with all the web technologies thanks to a wide range of experiences in the field.

[Matteo Ronchi @cef62]

@tannerlinsley I faced similar issues. As others have mentioned, the order matters. "types" must be the first for every entry. If I set "types" after "default," it fails to recognize the import path. @NoriSte

[TypeScript @typescript]

TypeScript 5.0 Beta is now out to try! 🚀

Now with ES decorators, better modes for modules in Node & bundlers, new inference tools for library authors, JSDoc support - and last but not least, some great speed and size improvements!

[Mateusz Burzyński @AndaristRake]

const modifiers for type parameters are coming to TS 5.0, I had a feeling that this might happen soon

loving, loving it ❤️

declare function bar<const T>(obj: T): T;

bar([1, 'foo']) // readonly [1, 'foo'], and not (string | number)[]
