@heyimcarlos_dev @EffectTS_ I’ve tried several solutions, but each one introduced new problems and resulted in an even worse UX.

What behavior do you expect?

[Maximilian @maxedapps]

Cloudflare + Alchemy (@alchemy_run) + Effect (@EffectTS_ ) is such a winning stack with AI agents, it's not even real.

Provides pretty much all the primitives you need for building any kind of application and ensures proper guardrails & rules to keep the agent on track.

And all the infra lives in code - which is how it should be with AI agents.

Excited to have @samgoodwin89, founder of @alchemy_run, joining us as a speaker at the Effect NYC meetup!

@zeeg @matteocollina I am getting on the effect train.

Being able to track what errors can happen and if they are all handled is something that I am sure you can eventually get an LLM to do, or you can do it in less than a second and it's 100% reproducible.

[Federico Biccheddu @_f15u_]

@YoussefTharwat_ @ThePrimeagen @zeeg @matteocollina For example: feedback loop from TS compiler. It gives back errors when failures are not handled

@TimZolleis @tobimori Are you gonna attend Effect Days too?

If so, looking forward to meet both of you 🙌

[Federico Biccheddu @_f15u_]

@tobimori @TimZolleis We're gonna have it in December, right? RIGHT?

[Federico Biccheddu @_f15u_]

@TimZolleis @tobimori The screen is basically the same initial code wrapped on an `Effect.gen` basically!

[Federico Biccheddu @_f15u_]

@TimZolleis @tobimori - `createServer` not scoped (`acquireRelease`)
- `request` should be changed at the end/edge
- Schema to reduce boilerplate
-`fail` + `fault` become useless with specific errors + matching
- `faults` can be just error accumulation

And this just from the incomplete screenshot

@alejandronanez Waiting for you at the next-next stop then 😏

[John A De Goes @jdegoes]

More goodies coming from the @zivergetech workshop on @EffectTS_ that's happening TOMORROW. 👀

Going to have laminated guides ready to hand out at Effect Days 2026. 🚀

[Federico Biccheddu @_f15u_]

@LukeberryPi In what context/domain?

[Federico Biccheddu @_f15u_]

@tsoding You can use `-ai` dork

[Federico Biccheddu @_f15u_]

Hey @paolino, been using Fastpotify daily!

Feedback: filter, even locally, playlists when using "Add to playlist".

It's extremely annoying to look for a specific playlist.
- is not clear how are they ordered
- there is no visual feebdack
- no folder (IIRC coz Web API limit)

Update to Effect V4 if you haven't yet!!

Did a big sweep over the weekend finally migrating our @superwall monorepo to @EffectTS_ V4.
400k LOC PR later our services are now ~30% faster and use quite a lot less memory.

[Effect | TypeScript for the AI Era @EffectTS_]

This Week in Effect #134

→ @kitlangton unleashed Astra on Effect.

→ @dillon_mulroy will never again start another TypeScript app without Effect.

→ @mattpocockuk praising Effect docs.

@devstein64 @foldkit @devinjameson Unless by "front-end framework for agents" means something else here, like a GUI for agents or something

[Federico Biccheddu @_f15u_]

@devstein64 @foldkit by @devinjameson is one of my favorites at the moment!

[Federico Biccheddu @_f15u_]

@britocoding @EffectTS_ I'm helping a Tech Lead friend to adopt it on a React SPA w/ lot of anti-patterns/different ways of doing things.

Shown how adopt incrementally using ManagedRuntime and Atom. After it clicked, he refactor a complex enough area successfully and understood the real benefits.

[Federico Biccheddu @_f15u_]

I'm really excited about all the libraries/DSLs around @EffectTS_. They all:
- abstract away a lot of complexity/boilerplate
- have close/coherent and higher DX standards
- compose natively with Effect itself
- solve previously ignored problems due to accidental complexity
