Amazing talk by @PopovaViolina on using @EffectTS_ to tame race conditions, errors and retries!

And just like that, the first day of @ReactAlicante is over. Great talks today, and super excited for my @EffectTS_ talk tomorrow.
This conference definitely feels more like a vacation than a typical tech event. Sun, sea, good people, and actually useful sessions. Already looking forward to day two.
Hasta mañana ☀️⚛️

I was in on @EffectTS_ two and a half years ago, receipts:
Very excited. I remember a number of years ago there were a number of attempts to do similar things in regular JavaScript that didn't catch on. I think TypeScript has made it much more viable. I think it's one of the most important libraries being developed today.

I sort of feel like @astrodotbuild should do something to integrate with @EffectTS_ some how. I have no actual ideas here so don't ask me, it just feels *directionally* the right thing to do.

in Executor v2, it's actually taking advantage of effect's error system now
all of the error states will have clear error messages, along with that, for the ones that are fixable via your agent i.e apps using the wrong auth they will include a prompt to use

genuinely this is a super powers stack
technology that was too annoying to do before ai which now has become 100x easier to adopt leading to way better outcomes
