Typescript Runtime Validators and DX, a type-checking performance analysis of zod/superstruct/yup/typebox

  What's prompted me to look at this is my tRPC+Zod editor experience at work has become unusable. 2-3 seconds to just get autocompletion options on a tRPC path, and then another 2-3 for the next path, repeat. When investigated using TypeScript's tracing tools the data entirely points back to my team's Zod DTOs. What I learned is that Zod's performance is okay at the start, but when you start using methods like .extend/.pick/.omit (and so on) the performance regresses in the order of a magnitude. Rather than making this into a "Zod considered bad" post, I wanted to investigate how the alternatives which can be integrated with tRPC fare, and see whether I can do better.
