Wild times.

I've joined @heartbeatchat.bsky.social as a founding engineer! It is my privilege to be among their first engineering hires joining to take a platform already changing lives to the next level. It's cool too that they're using @prisma.io, @effect-ts.bsky.social, and other great tech. Here we go! 🎉 🧑‍💻

Just dropped a seasonal ish update on my Graffle project, recapping some recent happenings and looking forward a bit. Ended up actually being a pretty productive few months :) github.com/graffle-js/g... #graphql

Thanks @zed.dev and Kyle Barton for github.com/zed-industri.... Zed just got ahead of VSCode here where this functionality is only available after an extension has been installed. Great work! #typescript

Working on Optics for Kit. Aiming to drop all traitable get/set/update ops on data structures meaning those that can be provided via polymorphic traits e.g. `Optic.at(...)` works for e.g. tuples or structs while `Optic.ix(...)` works for e.g. arrays or records. github.com/jasonkuhrt/k...

Just shipped type-safe regex in @wollybeard/kit using Arkregex ⚡ github.com/jasonkuhrt/k.... Arkregex comes from the great David Blass who is also working on @arktype.io. What a great quality of life improvement, thanks David! #types #regexp #typescript

Flo end is a complex command doing quite a few things. It now has a dry run to help gain confidence before carrying out its slew of side effects. Learn more at: github.com/jasonkuhrt/f... #claude #cli #fish #workflow

Consolidating some stuff in Kit such that type and value level lens will also have a superset JSONPath syntax and this obviates the need for something like Obj.get from kit too. #typescript #jsonpath #fp #lens github.com/jasonkuhrt/k...

Feels like we’re at the point now with Siri where it’s just pure brand damage for Apple. At least in our home Siri on HomePods are a daily joke, total ineptitude. Privacy aside, if only I could have them IO with my Claude account. #siri #apple

Thanks to @colelawrence.com I today discovered ampcode.com. Reading their changelog (at /news) and getting excited. There are some great ideas here (I'm excited to read other devs' prompt flows), pace of change appears breakneck, and they're removing paper cut after paper cut that I've ...

Hoping to make it to the first @effect-ts.bsky.social meetup in NYC next week! Looking for a few nights low key lodging, like couch surfing 🛋️, if you or someone you know might be up for the very random act of hosting this Canadian please DM me! 🙏🏻🫶 luma.com/ihoo6kxy?tk=...

Cool to see this @grain.social. This year I migrated off of Instagram to my personal website kuhrt.me/capturing. But I do enjoy a healthy social experience. Maybe that's what Grain is/will be/remain as :). I am sceptical that pretty much any social platform of sufficient "success" (scale) will ...

Thanks for that poetry, Claude. ✨ #ai #types #rust #scala

On design: Thinking of 'One obvious way' versus 'expressiveness' (e.g. Python versus Ruby), not as a dichotomy but as a continuum, have the expressiveness AND then allow layering on the 'obvious way' for <thing> ([mono]repo, package, file, block, ...). In other words when designing an interface, ...

I would appreciate a TypeScript LSP MCP, Claude Code could turn a laborious non-deterministic process (easily 1+ minutes on large code bases) of identifier renames into a few seconds deterministic process. For now I try to do that for Claude but steals some degree of flow from me.

Thank you LambaTest for becoming Graffle's first recurring monthly sponsor ❤️! I couldn't be more delighted 🍻. Check them out at www.lambdatest.com.

I’m looking for my next opportunity 👨‍💻, short/long contracts or part/full time. My experience is 15 years across the stack and architecture often focused on open source and next generation developer tooling, libraries, frameworks in the TypeScript space. If your company or project is ...

TIL! How subtle is that, damn. Seems like a good candidate for a lint rule.

Musing over an idea I'm calling "Autotest" to scratch my own itch that marries JSDoc tests into generated test files with comprehensive support across types and terms (values). Would you use this? Thoughts? github.com/jasonkuhrt/k...

I've been making big strides with Graffle the past couple weeks, such as around the static builder and support for variables, docs, and type level string parser. Accordingly I revamped docs to cover everything one should need to know about these features. Here's a rundown:

Recent improvements to github.com/jasonkuhrt/flo: - project selection (default is cwd) - interactive project and issue selection via list - flo start/end aliases for flo/flo rm - polish like flo end cd'ing back to project

So last month I gave two talks at GraphQL Conf in Amsterdam and it was a lot of fun and challenge for me but unfortunately a glitch means my talk on Polen (polen.js.org) will never see the light of day, though my shorter talk on Graffle (graffle.js.org) will.

I've seen lots of agentic workflow tools popping up this year. I started my own called flo github.com/jasonkuhrt/flo :) -- Starting simple but will iterate over time. So far combines use of Claude Code, GitHub issues, Git worktrees, and some naming conventions.

I am excited for voidzero.dev/posts/announ... and will begin using it this week on some of my projects (more on that soon). Thanks @vite.dev @vitest.dev etc. and all the peeps involved reaching this point. Every tool in the chain scratches an itch I have.

Today I shipped a static document builder for Graffle, learn more here graffle.js.org/guides/gener... (PR github.com/graffle-js/g...). It unlocks new usage patterns like defining queries outside of a Graffle instance, at module level, totally static, reusable, passable to instance.

Plotting a course for some serious type performance work in github.com/graffle-js/g.... Thanks David (github.com/ssalbdivad) for ArkType Attest! www.npmjs.com/package/@ark...

Today is my last day at @the-guild.dev! I still intend to continue my work on projects like polen.js.org, and graffle.js.org. I've been head down for a few months culminating to my talks at @graphql.org Amsterdam conference two weeks ago. Feel a bit burnt out but also excited for new adventures.

@hiogawa.bsky.social‬ thanks for your work on Vite RSC, using it this week on a framework we're building at @the-guild.dev! I ran into one issue with RR which is that our routes.ts module has virtual imports. I adjusted your rr plugin code to use environment module runner import instead ...

I am thrilled (and nervous 😬) to have been selected as a speaker to share work we’re doing at @the-guild.dev on GraphQL API documentation. It’s still super early but being worked on in open at github.com/the-guild-or....

I pushed my knowledge/muscle-memory on Vite Dev/NodeJS Package SubPaths/Tree Shaking/Isomorphic FS/Path/... github.com/the-guild-or...

Hello github.com/jasonkuhrt/kit Over the past weeks I have been passively factoring out utilities I use across my projects. For now my niche thing and changing constantly, but I am creating it as a proper library. It has hints of @effect-ts.bsky.social mixed with es-toolkit/ramda/fs-jetpack/...

I want to make a @zed.dev extension that leverages @typescriptlang.org semantic analysis allow syntax theme authors (including would be me :)) to apply rules 🧑‍🎨 also on arbitrary static analysis ala. what @typescript-eslint.io is doing for listing. Leverage TS Go to make it perform.

@ieni.dev! Please bring Glimpse ( marketplace.visualstudio.com/items?itemNa...) to @zed.dev! ❤️ This time you'd get to write it in 🦀😄. I think it would integrate really nicely with Vim concept of key chords since they do exactly that: <key><...key> -> do something 🚀.

This is going to be great, we can finally steer people away from using POST by "default" (PO's require effort et all) on GraphQL because QUERY is an ideal replacement 😍

I'm so happy @zed.dev exists. Finally made the switch yesterday. Never going back to VSCode. Thanks for the great last ~7 years. But it became too buggy and slow for me on an hourly basis. 🤷 (being a vim user definitely made me hit more rough edges than otherwise would have).

Went down a rabbit hole on TS "... cannot be named ..." error. There appears to be a bug in TS with ESM re-exports and namespaces, but I'm not sure! Tricky whatever it is. I've tried to document the issue clearly here (+solution): github.com/jasonkuhrt/r.... TS issue here: github.com/microsoft/Ty...

I submitted two talks for this year. One for Graffle and one for a new project I recently started at @the-guild.dev. More to share about the latter in the coming weeks :))

Hey @vlt.sh @ruyadorno.com I am looking for a library that not only reads package.json but also normalizes it (e.g. bin is string or record, but normalized should just be record). Does any of your libraries do that?

🙇‍♂️ Thank you @vlt.sh @ruyadorno.com et al. for giving the community a cohesive toolkit for working with packages docs.vlt.sh/packages. I wish I had some of these when I was building Paka with @schickling.dev ❤️!

I didn't not expect that building the devtools messaging protocol for @livestore.dev would turn out to be one of the most difficult parts to build. In order to support reliable and efficient messaging (supporting transferables), I ended up building a local networking protocol called "Webmesh".

I finally clawed myself out of a self-inflicted rabbit hole. I will not be doing "that" again (multi-month PRs). Graffle is in a better place at core with a brewing reactive config system but there are many fast follows left to do. Happy to be back on track again! github.com/graffle-js/g...

If you need a sublet this summer in Montreal my home is available! It's dear to me and excited to host someone. :) montreal.craigslist.org/sub/78435679...

I have been working hard this year to bring clarity to my life. A part of that involves reviewing implicit contracts I've had with myself about workaholism. I love working on open source libraries but it cannot anymore come at the expense of my own life. So for example, today (Sunday) I am ...

This is another great example of how well @cloudflare.social is playing with the open source ecosystem: not a simple use case report but a full-fledged and generic new API proposal for @vite.dev. More companies should have dedicated teams actively working with open source projects like they do.

Recent improvements to my TypeScript library template. Many dependencies updated and a lot of streamlining around ESLint github.com/jasonkuhrt/t....
