Domain modelling with State Machines and TypeScript by Carlton Upperdine

• zod

  290 30,477 9.1 TypeScript

  TypeScript-first schema validation with static type inference

I've found that a liberal use of zod basically eliminates this problem. I wish there was an option in typescript to force all the functions like fetch to return unknown instead of any. It could eliminate this problem almost completely I think.

• io-ts

  80 6,604 4.9 TypeScript

  Runtime type system for IO decoding/encoding

My fave is still io-ts (https://github.com/gcanti/io-ts/blob/master/docs/index.md) as I find it more flexible than zod at the ingress. The author is also working on the Effect ecosystem which also looks interesting.
