ALT Screenshot of a tweet by Marko praising Effect, calling it โthe best experience TypeScript can giveโ and saying it took him a long time to appreciate because he was mixing it with Promises. The tweet includes a code snippet showing a TypeScript function returning an Effect.Effect with explicit output, error, and dependency types, illustrating Effectโs type-safe approach to managing complex workflows and failures.

the effect http client is really good, and now that models are writing most of the code there's a lot of stuff like this that would've been annoying before
Cloudflare is another great example of something too annoying before that I'm starting to heavily use

Can you get all the benefits of effect using it with svelte/sveltekit?

โEffect code tends to be verbose, but thatโs not necessarily a bad thing for your agentโ
Your DX depends now heavily on AX. Treat your agent well.
Prioritise it over your own coding taste

100%. Effect code generated by coding agents is so much better than vanilla typescript.
first time working on an @EffectTS_ codebase and i already fell in love
i don't know if it's the guardrails or the spell it cast on the model, but i'm oneshotting stuff like never before

@EffectTS_ is the best experience typescript can give, this is simply amazing. It took me so much time to realised it, as I was mixing it with promises. This is beautiful,

OpenCode 1.17.3 can reference other git repos or local folders
๐๐๐๐๐๐๐๐๐๐: {
"๐๐๐๐๐๐": "๐๐๐๐๐๐.๐๐๐/๐ด๐๐๐๐๐-๐๐/๐๐๐๐๐๐-๐๐๐๐"
}
gives it full access to the effect codebase, here's how we use it

ALT Dane Knecht joking that a new version of OpenCode would already be released if Dax Raad had listened to him earlier. he tweet includes a screenshot of a message from November 2025 where Dax says, โeffect is really great but i basically will never use it.โ Below, Michael Arnaldi replies, โNever say never :)โ. The post humorously contrasts Dax's earlier skepticism about Effect with OpenCode's later adoption of it.
