  • JavaScript schema library from the Future 🧬
    18 projects | dev.to | 21 Feb 2025
    Talking about ArkType, they use the same approach with eval and have similar potential to ReScript Schema, but their evaluated code is not there yet. Currently, their operations are a little bit slower, and the schema creation is significantly slower. But I can see that it can somewhat catch up in the future.
  • Error Handling for fetch in TypeScript
    4 projects | dev.to | 18 Feb 2025
    …but that’s a lot of no fun, dangerous work. Better to use a library that has already solved this problem like Zod or ArkType. It’ll ensure the types match up, and if not, give you an error response that _somewhat_ gives you a clue as to why the decoding went wrong, way more thorough and verbose than JSON.parse’s not so great runtime error messages.
  • Encoders and Decoders in TypeScript
    3 projects | dev.to | 17 Feb 2025
    You can get an unknown return value, so you’ll have to type narrow to your type. (We’ll avoid doing type narrowing in this post and assume you’ll use something like Zod or ArkType heavily in your decoders).

  • ArkType 2.0: Validate 100x faster with DX that will blow your mind
    2 projects | news.ycombinator.com | 17 Jan 2025
    ArkType 2.0 is a no-setup solution for schema validation with a new style of type-safe API that parallels native type syntax while offering validation functionality like Zod or Yup.

    It also brings types to runtime in a way they've never been available before. They can be introspected and compared just like `extends` in native TS.

    Thanks for your patience, and I couldn't be more hyped to see what you do with it!

  • Introducing Hono OpenAPI: Simplifying API Documentation for HonoJS
    5 projects | dev.to | 7 Dec 2024
    The original library only supports Zod. While Zod is excellent, many developers use alternatives like Valibot, ArkType, and TypeBox. hono-openapi is validator-agnostic, offering first-class support for multiple libraries.
  • Type-Safe Env Vars in Remix - A modern approach with ArkType
    4 projects | dev.to | 14 Jun 2024
    Aside from updating Remix (from 1.7 to 2.9) and switching from Zod to ArkType, I’ve introduced a makeTypedEnvironment helper to streamline handling environment variables in both server and client environments. Additionally, I’ve optimized the codebase by removing the typedPick method and refining imports to ensure server code doesn’t leak into the client bundle.
  • Using Arktype in Place of Zod - How to Adapt Parsers
    4 projects | dev.to | 12 Jun 2024
    Arktype has been on my radar for a while now, it offers similar validation capabilities but with some unique features that caught my eye, like the way it lets you define validators using the same syntax you use to define types.
  • Library for benchmarking TS types
    2 projects | /r/typescript | 9 Dec 2023
    I primarily rely on that approach to benchmark ArkType's types.
