    Qué rico. Si tenés chance meté un proceso de code review fuerte, y para el tema de I/O probá a usar ó que les da una solución obvia al tema de "tipos para lo que devuelva el backend", aunque es en realidad mucho más capaz que eso.

    My fave is still io-ts ( as I find it more flexible than zod at the ingress. The author is also working on the Effect ecosystem which also looks interesting.
  • Can someone recommend a library for data parsing similar to Zod, but with better support for input transformations/preprocessing?

    Yeah, there are a few new concepts and it's not the easiest to pick up right away. The best introduction is here on the main documentation page.

  • Typescript advanced bits: function overloading, never and unknown types

    A good way to significantly improve the reliability of your app is via improving type-safety by moving away from using any to unknown. One relevant example could be when you type your backend responses and when stringifying JSON to using unknown combined with some sort of runtime type checking. It can be done either by using built-in functionality like type guards or using an external library like io-ts, zod or yup.
  • I found 10,000x faster TypeScript validator library

    Usage of TypeBox is similar with io-ts and zod, but it is much powerful and faster than them. Also, TypeBox can generate JSON schema very easily. Therefore, if you're looking for a validator library for new project and not suffering from legacy codes, I think TypeBox would be much better choice than io-ts and zod. TypeBox can totally replace them.
  • Validate your data with Zod
    2 projects | | 31 Oct 2022
    This check can be done with different libraries like: io-ts, typebox, or zod. These libraries allow you to create objects that represent your typescript definitions. Then, these objects can be used at runtime to validate the received data, in addition, you can also convert this object to a Typescript definition to have all the benefits of using typescript. These objects can be called schema validations because they are responsible for the data validation.
  • TypeScript-JSON is 10 ~ 1,000x times faster than ZOD and IO-TS

    Being proud of such performance enhancement, I hope many TypeScript developers to adapt my library. Advantage of typescript-json is not only better performance, but also easy usage exists. typescript-json does not require any extra schema definition and just requires only one line with pure TypeScript Type. Thus, what about using my library typescript-json instead of io-ts or zod?

    It's not external to TS. You write your types by passing object literals to the functions that generate the validators; TypeScript then infers shockingly precise types, which can be extracted using TypeScript's type manipulation utilities.

    It does support generics [0].
