Effect | TypeScript at Scale

Effect v4 is in beta. 🚀 Rewritten runtime. Smaller bundles. Unified package system. The most ambitious release we've made so far. Here's what's new. 🧵

Hey. Sentry supports @EffectTS_ now. 😎 github.com/getsentry/sent…

TypeScript-go enhanced with the Effect LSP experience github.com/Effect-TS/tsgo

At yesterday's Effect Office Hours, @MattiaManzati presented a TSGo version of the Effect LSP (currently in alpha). A wrapper for TSGo that builds the Effect LSP, with Effect-TS diagnostics and quick fixes, targeting Effect V4 primarily and Effect V3. youtube.com/watch?v=8djMEk…

@dillon_mulroy @zeeg

@zeeg unironically, the code in pi-coding-agent is stellar - most specifically around the disciplined use of abort controllers - you rarely see this done right and well.

I need some great examples of idiomatic code in languages like TypeScript e.g. orpc/trpc-like interfaces where its very easy to reason about, low boilerplate, "obvious" on the surface and fairly explicit in behavior What are your favorite?

Join us for Effect Office Hours tomorrow! 🔥 March 18 -- 10 AM ET / 15:00 CET youtube.com/watch?v=8djMEk…

T3 Code is built pretty much entirely with Effect and very large portions agent coded without much context engineering. Ive just had to nudge it that we’re using v4 and it Will go dig in the mode modules and read the inline documentation whenever it gets stuck / hits an old api

@SharpCoder @EffectTS_ GPT-5.4 is exceptional at Effect, just add the effect repo as a git subtree to give the agent access to best practices, skills don't work well. Check out effect.solutions

twitch.tv/timmeeeeeeeeh Working on clanka (effect native ai agents) and answering effect questions.
