I'd heard the "parse, don't validate" mantra before but just recently tracked down @lexi_lambda's original post and it finally clicked. Honestly a relief have such a concrete explanation of why using tools like @zodtypes and @pydantic "feels" so right. lexi-lambda.github.io/blog/2…

I shipped a library! zod-fetch gives you a TINY wrapper to help you make any fetch function type and runtime-safe. If you've ever been intimidated by trying to hack together fetch and Zod, this library should be perfect.

Replying to @DavidKPiano @kentcdodds
We built schema based forms using @HookForm + @zodtypes + form components we created + custom components can be added. We can manually compose forms, or generate from JSON and it really saves so much time (and so many calls to useState)

Zod's `.catch(default)` method is SOOO good. Thanks @colinhacks

Did you know TypeScript doesn't provide runtime type safety? @zodtypes is here to save you. Plus it works great with Convex!
Convex
@convex24 Jan 2023
Validating user input for serverless functions is important even with end to end typescript. Use zod with Convex to get type safety and regular safety. buff.ly/3Hv2Rx1

Playing with @zodtypes to validate some API results in my #reactnative app, what a delight! 😍 I love the simplicity of the @zodtypes API. No more excuse to protect your frontend app from bad data format 🔒
