Saw a writhing ribbon snake mating ball today - very active with the warm weather! (Don’t watch if you have a snake phobia… it was a lot in person, 😝 🐍)

I have a private db of Japanese print sales and I used Claude Code to make a report analyzing this month's auctions: data.ukiyo-e.org/auctions/asi... identifying under-valued lots, rare prints, comparing prints across auctions. Normally VERY hard to get this guidance.

The top Japanese print auction listings for the upcoming auction season happening in March 2026. 3 great wave prints are featured.

Tanstack Server functions have both middleware and input validation. I have no need for a public API at the moment, but that might change. For now they meet my needs very well!

John Resig @johnresig.com · 25/10/2025

I've been using @tanstack.com Start for a new project and it's super good. The server functions completely replace the need for TRPC/GraphQL/REST, the middleware is composable and fully typed, and having TSRouter's nice typing and stateful search params is icing on the cake. A+!

In an era where folks are using AI to remove creative and artistic expression it feels especially poignant to see these very handmade art pieces depicting technology. I hope we can continue to pass down our creative pursuits to future generations, like Marilou is doing.

Got to see two dream art pieces yesterday: weavings depicting computer chips by the Navajo weaver Marilou Schultz. They were on display at MoMA and were incredible to see in person. So intricate and detailed, but also handmade and steeped in tradition. More info: www.moma.org/magazine/art...

Oh, to clarify - the issue with plugins is with Biome, not Nx!

John Resig @johnresig.com · 15/02/2025

Yeah, that's a good callout, that's something that doesn't appear to be working right. I do have the default extensions cache rule turned on, but it does seem like it's not caching it. Having to have a proxy worker seems... not ideal. I'll reach out to the CF folks.

John Resig @johnresig.com · 15/02/2025

It really is! So good :)

John Resig @johnresig.com · 15/02/2025

So this is all server-side render time, so wall time is the total time it took to process the request and return it to the user. Whereas CPU time is the time actually spent rendering. Sub-requests are fetch()es to other resources from the worker (usually image upload handling).

John Resig @johnresig.com · 14/02/2025

Ah yeah, I should just remove it, it's a janky old wordpress thing that I haven't updated in over a decade, lol.

Awesome! Really glad you're enjoying it!

John Resig @johnresig.com · 14/02/2025

It's certainly something I considered, for sure! Thankfully R2 is S3-API-compatible, D1 is just sqlite, and the thin wrapper around React Router is easy to replace with something else. I'm finding it to be much better than rolling my own (which I was doing before).

010

John Resig @johnresig.com · 14/02/2025

So I made a lot of architectural changes. Previously it was on Digital Ocean with some ancient Node template thing, now it's full React SSR. Hosting was $5/month, but slower, and not SSR - image hosting was $$$, easily over $100/month. My hosting costs would've been higher if I was doing SSR, too.

John Resig @johnresig.com · 14/02/2025

I ported ukiyo-e.org over to @cloudflare.social Workers + R1 (image hosting, about 1TB) + D2 (for DB and search) recently and I'm super happy with it, it's a great experience! Have it using React Router v7 + React 19, about 11 mil dynamic requests/month, served in under 35ms! Total cost ~$25/month.

We do a ton of it at @khanacademy.org, for all components and in different states. Super helpful in catching regressions. We use Chromatic on top of @storybook.js.org.

0112

John Resig @johnresig.com · 19/01/2025

React, React Router (v5 currently), GraphQL w/ Apollo, custom design system, ESLint, Prettier, TS, Jest. In the process of moving to a monorepo setup, probably using @nx.dev. Will likely move to vitest and Vite for prod builds post-Rolldown. Want to use Biome but blocked on some missing plugins.

290

John Resig @johnresig.com · 17/01/2025

We just moved @khanacademy.org over to using @rspack.dev today for our prod builds, from Webpack 5. We saw build times improve by about 2min or so (approx. 3min -> 1min). It was extremely easy to move to from Webpack, highly recommended for anyone on the fence!

Haha, awesome! I've still got mine on display (appropriately) in my bathroom!

John Resig @johnresig.com · 13/12/2024

I'd do the B/W. It looks like the keyblock on the color one has been pretty much obliterated with a lot of the fine detail lost, unfortunately. I'm guessing it's a later meiji period printing, based on the pigment colors, but with the original (beaten up) blocks?

010

John Resig @johnresig.com · 13/12/2024

So cool! You can see the impact of this pigment being imported into Japan on kimonos (and in prints). Before (1847): ukiyo-e.org/image/mfa/sc... After (1878): ukiyo-e.org/image/arteli...

We are now 100% using Lingui for translation at Khan Academy! Wrote some gnarly codemods to completely convert our codebase and then set up a nightly job to convert `master` and fix bugs as they came up. Made it possible to do the conversion in one morning with no errors!

John Resig @johnresig.com · 10/12/2024

Haha yeah, I just fixed it - it was firing every minute!!! Messed up the cronjob syntax, lol. Thanks for the heads-up.

Some of Khan Academy's AI work was featured last night on 60 Minutes with Anderson Cooper: www.youtube.com/watch?v=Ia3C... it's been really cool getting to work on this, really glad that this is having a positive impact on students and teachers!

Mask buddies!! It’s good for so many reasons… jealous of your pottery class, that sounds like so much fun! Definitely share what you make, would love to see it!

John Resig @johnresig.com · 05/12/2024

This is actually really great news! We were finding memory usage to be pretty comparable between Webpack and Rspack (even though Rspack is orders-of-magnitude faster) so this would be an even greater win!

This Spotify Wrapped tracks. Justice’s Coachella sets were so good that it reinvigorated my love for them. A ripped copy here: m.soundcloud.com/user-6372306... I think this year may be the first year where the majority of my music listening happens outside of Spotify (esp YouTube concerts)

If you've already adopted the v3 future flags then it's not hard at all, I ran the code mod here: reactrouter.com/upgrading/re... most of the challenging bits after were Cloudflare Worker-related, which is pretty specialized.

Finished upgrading to Lingui v5 today. Was pretty straight-forward! Some good bug fixes, which were appreciated. We're still just using the basic React macros, not using the useLingui macro yet - but that works fine for us. Still the best React i18n framework, IMO.

Hey yeah - feels good to be here! 👋

John Resig @johnresig.com · 03/12/2024

The automatic type instrumentation didn't happen automatically with the codemod, but the types were generated by Vite, so it was just a matter of manually importing the types and adding them to my function exports. Pretty straightforward!

110

John Resig @johnresig.com · 03/12/2024

I was already using all the v3 future flags so running the codemod mentioned in: reactrouter.com/upgrading/re... got me really close. I had a couple other issues that were Cloudflare worker-specific, but I was able to address those pretty easily.

Playwright's new Aria Snapshot comparison tool is super cool: playwright.dev/docs/aria-sn... surprisingly, I've seen no other library capable of this. Looking at their implementation it looks like they wrote it from scratch! github.com/microsoft/pl... It'd be very cool to see this OSS'd separately!

Ohh! Ok, I've been using Smart Placement, but I guess I hadn't clocked that it could (potentially) work at the route-level. That's super cool, thank you!

John Resig @johnresig.com · 03/12/2024

This is a great write-up. Tons of very smart, actionable, advice on improving React INP performance. (The jQuery-is-better bait is pretty hilarious, probably says more about the complexity of most jQuery sites.)

1172

John Resig @johnresig.com · 03/12/2024

This is really cool! Maybe this is my ignorance, but how does CF "learn" that a particular route has a specific data requirement? I understand how it could at the level of the entire worker (seeing that a specific D1 db is needed, for example) but I don't see any hints for the routes? Curious.

John Resig @johnresig.com · 03/12/2024

I switched a Remix-using side project over to React Router v7 this past weekend and the new route-level type safety is pretty great! reactrouter.com/explanation/... been looking forward to this for a long time, code is a lot less clunky now being able to remove useParams/useLoaderData/etc.

v5 of Lingui was just released. We've been working to adopt Lingui at Khan Academy and it's by-far the best i18n library around. The use of macros, SWC integrations, deep React integrations, and idiomatic POT/PO file support makes it a huge win. lingui.dev/blog/2024/11...

My account was like that for a long time, but the bit flipped when Elon took over, unfortunately. The ads were super garbage too, which made the experience even worse, shockingly.
