Effect | TypeScript for the AI Era retweeted
Had a great chat with @joelhooks about @alchemy_run, @EffectTS_, @foldkit and how AI is making high discipline, rigorous programming techniques accessible to everyone.
what if you could literally fork any business? @samgoodwin89 explains how you and your agents will be doing just that with Alchemy and Effect

🔥 Just 2 days until @EffectTS_ Miami #3!
Three amazing speakers, three perspectives on TypeScript, Effect, AI, and how we build software:
🎤 John De Goes (@jdegoes · @ZivergeTech) — "Harnessing AI Models with Effect TS"
🎤 Harry Solovay (@harrysolovay · @crosshatchdev) — "Advanced Design Patterns with Effect"
🎤 Devin Jameson (@devinjameson · @foldkit) — "Foldkit: Frontend for Agents and Humans"
Monday, Nov 9 · 5:30 PM

Special thanks to @ayalstern for providing the venue! 🙏🏻
Come hang out!

Excited to talk at Effect days!
Excited to welcome @RhysSullivan to the Effect Days 2026 speaker lineup! 🇮🇹
Rhys built @executorsh with Effect, and we're looking forward to hearing about his experience using Effect in production.

I’ve been running a @factory workstream around the clock for three days distilling ARTEX into a spec and then rebuilding it from that spec in @EffectTS_
It’s kinda insane that this works as well as it does especially since I can’t use opus/sol and some of the features like a TLS-terminating MITM proxy are quite complicated
and it’s quite large ~ 100kLoC
Effect | TypeScript for the AI Era retweeted
.@EffectTS_ is inevitable now. foolish not to use it by default on new projects imo
more and more framework will follow
Effect | TypeScript for the AI Era retweeted
effect fibers are one of the most fascinating pieces of engineering i've seen in the typescript ecosystem
no worker threads, no OS threads. just a custom interpreter, an execution stack, and a cooperative scheduler built on top of the JS event loop
absolutely insane engineering

🔥 𝗝𝘂𝘀𝘁 𝟯 𝗱𝗮𝘆𝘀 𝘂𝗻𝘁𝗶𝗹 𝗘𝗳𝗳𝗲𝗰𝘁 𝗠𝗶𝗮𝗺𝗶 #𝟯!
Really excited about this one! We’ve got three amazing speakers joining us on Monday, each bringing a different perspective on TypeScript, Effect, AI, and how we build software.
🎤 𝗝𝗼𝗵𝗻 𝗗𝗲 𝗚𝗼𝗲𝘀 (@jdegoes · @ZivergeTech)
“Harnessing AI Models with Effect TS”
🎤 𝗛𝗮𝗿𝗿𝘆 𝗦𝗼𝗹𝗼𝘃𝗮𝘆 (@harrysolovay · @crosshatchdev)
“Advanced Design Patterns with Effect”

“Foldkit: Frontend for Agents and Humans”
If you’re into software engineering, curious about @EffectTS_, or just enjoy learning from people doing really interesting work, come hang out!
We’ll have some great talks, food, drinks, and plenty of time to meet other developers and exchange ideas.
And if you’re a developer, CTO, or engineering leader in Miami, I’d especially love to see you there!

Deploy any complex infra in a few minutes
Use @EffectTS_ @alchemy_run and @Cloudflare
Trust me. Give your agents Alchemy and Effect docs and it's gonna look like a miracle.

Yesterday the tsrs team cooked and shipped `tsrs --lint` as a drop in replacement for Oxlint's typeaware tsgolint.
Today we shipped support for the @EffectTS_ rules as well!
Drop in a `--tsrs-lint` flag and watch your lint time go faster!
Effect | TypeScript for the AI Era retweeted
16 new rules for the @EffectTS_ LSP last week, also in tsrs and Oxlint.
They focus on spotting Effect boilerplate and rewriting it to the builtin: mapBoth, fromResult, catchNoSuchElement, failSync, isSuccess, etc…
And they come with quickfixes as well!

Quick hack to actually understand distributed systems and the actor model
Just read the this week in effect cluster series blog by @maxwellbrown
They’re actually pretty enjoyable and fun to read as well
Every engineer in our team has read it all by now
Effect | TypeScript for the AI Era retweeted
I made Vercel Domains, CAFE style.
A fun excuse to hack with @Cloudflare, @alchemy_run, @foldkit, and @EffectTS_ (and put the new Blocks and Layers API through its paces).
As @RhysSullivan pointed out, this is a deceptively complex UI:
- URL synchronization
- Debounced requests, cancellation, and stale responses
- Cached results, expiry, and retry
- A virtualized list with progressive data loading
- Filters and sorting
- SSR, hydration, mobile keyboards, focus, dialogs, and accessibility
There’s a lot of behavior here, but the state, transitions, and effects are explicit. And Story + Scene tests let us pin down the subtle stuff that’s easy to break.
Alchemy declares and deploys the Cloudflare Worker, assets, and custom domain. The backend serves sample domain data through Effect RPC.
Foldkit goodies used:
- New Block Composition API
- KeyedQuery
- VirtualList
- Story + Scene tests
- DevTools + DevTools MCP
(Uses sample prices and availability.)
Try it: domains.foldkit.dev

The Effect shilling will continue until typescript is not written without it
Excited to announce @rankintweets, CTO of @warpdotco, as a speaker at Effect Days 2026! 🇮🇹
Warp is also joining us as a Main Sponsor, helping make this year's event possible.

Enjoy!

I finally like effect now. Pump it into my veins
New: domain-driven design for Effect, in alchemy.run/domain.
Translate business requirements directly into working software and integrate into your alchemy infrastructure.
