I type script and I TypeScript

Red sky in the morning, shepherds warning

The clocks have gone back so sunrise is earlier!

Earlier this week we shipped a beta version of ts-loader 10 for webpack users who want to try out the TypeScript 7.1 beta. If you'd like to learn more about that, here's a write up! johnnyreilly.com/typescript-7...

Lola is working on some really valuable stuff here. Consider taking 30 seconds to answer this quick single question survey.

ts-loader@10.0.0-beta.0 for TypeScript 7.1 has just shipped! This version works with the new TS APIs. I'll put out a blog post soon, but release is on npm if you want to get it now. Thanks to @ashley-c.bsky.social for the review and catching some last minute gotchas! github.com/TypeStrong/t...

I'm still doing a little fiddling, but all being well I'll soon ship a beta version of ts-loader which works against the @typescriptlang.org 7.1 beta with the new Go powered APIs. The PR is here. github.com/TypeStrong/t...

TypeScript 7.1 Beta is out 🎉 🔶 Import Attributes 🔶 Source Phase Imports 🔶 Types: es2026 🔶 Types: Promise.allKeyed, Iterator.zipKeyed 🔶 Types: Iterator chunks/join/includes 🔷 An API for tooling ✨ 🔷 tsconfig: Content Mappers 🔷 Perf: 1.2-1.9x faster, 15-50% less memory

TypeScript 7.1 Beta is now available! Now with a preview API, content mapper support, new features, and some great optimizations. Give it a try and give us some feedback!

Chemotherapy round 9 ✅ - I'd like to pretend it's getting easier, but the reality is it's a slog. Just got to keep going

I’m pleased to see soft navigations count towards LCP. This was an argument I made when I worked on Google Chrome because single page apps can provide much faster UX. Let’s say goodbye to the outdated nonsense metaphors that JS is smog or a traffic jam. It never made sense — now we have the data.

A blog post on cross operating system test probes, using GitHub Actions. And, I promise you don't get this with most tech blog posts, a little anecdote about lockdown to boot! johnnyreilly.com/cross-operat...

I am looking for my next career opportunity! I’m an engineering leader, consultant, author, and open-source maintainer. I've been VP of Eng, written books, get 20M weekly downloads on NPM, and more. Know of a role you think I'd be a good fit for? Book time on my cal or DM me: corbincrutchley.com

Chemotherapy round 8 ✅

ECMAScript excitement 😉 This week @tc39.es advanced these proposals 🎉 4️⃣ Dynamic Code Brand Checks 4️⃣ Iterator Chunking/Includes/Join 3️⃣ Thenable Curtailment 2️⃣.7️⃣ default in export * from "mod" 2️⃣.7️⃣ export defer 2️⃣.7️⃣ JSON.parse options 2️⃣ BigInt from Exponential 2️⃣ Composites 1️⃣ Pulling in AbortController

ECMAScript excitement 😉 Congrats to @ashley-c.bsky.social from TechAtBloomberg on advancing the Composites proposal to Stage 2 at @tc39.es today 🎉 Composites are objects that are compared by value instead of identity. They are an evolution of Record & Tuple proposal.

I've been a little slow in publishing this, but this the story of me going from surgery back into the next stage of my treatment. Being fixed isn't jolly, but it's going as well as I could hope. And I do hope. johnnyreilly.github.io/reillys-on-t...

We have lost the morning light

I don't know why I care about npm URL parity between npmjs.com and @npmx.dev but I do github.com/npmx-dev/npm...

don't be nice.

Chemotherapy round 7 ✅

I've had two months off for surgery, but tomorrow I begin chemotherapy again. I'm nervous. But far less nervous than last time when it was a terrifying unknown. Now it's just a grim known. It's for a purpose and it's not forever
