Zod has become the go-to tool for type-safe data validation, but do you really know what’s going on behind the scenes?

In this talk, we are going to build a Zod-like library from scratch in a live coding session. We’ll dive deep into both the runtime and type-level mechanics, understanding how Zod works and why its API is designed this way.

This talk is intended for experienced developers who are familiar with TypeScript and have used Zod (or similar libraries) in the past. If you're ready to deconstruct a popular tool and understand its inner workings, this one's for you.
