I'm thrilled to announce my first OSS package: RN Flash Calendar 📅⚡
It's the fastest and most flexible calendar component for React Native, built on top of @Shopify 's Flash List.

Here are the things I'm most proud of:
Woke up with a crazy idea: what if my open source RN calendar library had ZERO dependencies?
Spent the full day re-implementing a bunch of date-fns functions, and now it's finally complete.
Yes, there are 7k expect calls and bun process all of my tests in 80ms. And you're
Officially in love with Moni's date picker. Isn't this the cleanest API you've ever seen?

One of the nicest things I've done for my own DX was copying React Native's Alert API. Previously, I was using a hooks-based approach which honestly sucked.
Managing alerts imperatively is so much easier and quicker:
Finished wiring the calendar with my Input component. Obsessed with how easy and elegant it is to validate and control the inputs - all thanks to @HookForm and some craft 🔥
As a product eng, I always hated to add date inputs since they were a pain in the butt to customize and
