  • Zod v4: 17x Slower? (and Why You Should Care) 🚦
    4 projects | dev.to | 3 May 2025
    My hunch was that Zod v4 started using eval (or, more precisely, JIT compilation via new Function) for validation. This isn’t a bad thing — libraries like TypeBox, ArkType, and even Sury use similar techniques for speed.
  • Welcome Sury - The fastest schema with next-gen DX 🚀
    9 projects | dev.to | 28 Apr 2025
    Sury uses new Function under the hood. This approach makes it the fastest schema library available, but also means it cannot be used in environments that don't allow dynamic code evaluation, like CloudFlare Workers. Most users won't be affected, but might be an issue for some. Regarding safety of the approach you shouldn't be worried. Everything embeded to the generated code is escaped and thoroughly tested. Also, other libraries like TypeBox and Zod@4 use new Function under the hood as well.
  • 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.

    20 projects | news.ycombinator.com | 25 Nov 2024
    If you were willing to bring additional zod tooling or move to something like TypeBox (https://github.com/sinclairzx81/typebox), the json schema would be a direct derivation of the tools' input schemas in code.
  • Zod: TypeScript-first schema validation with static type inference
    17 projects | news.ycombinator.com | 7 Oct 2024
    I'd recommend TypeBox[1] as an alternative, which has a runtime “compiler” for generating optimized JS functions from the type objects. It also produces a JSON schema, which can be useful for generating API docs and API clients if needed.

    It also has a companion library[2] for generating TypeBox validators from TypeScript definitions, which I'm currently using in an RPC library I'm working on.

  • Ask HN: What are you working on (September 2024)?

    Big fan of your work and impressed by your productivity. Currently reading https://www.oreilly.com/library/view/unifying-business-data/....

    Currently experimenting with programmatic generation of json schemas via https://github.com/sinclairzx81/typebox. Trying to maximize reuse of schema components.

    Was wondering if JSON BinPack is a good serialization format to sign json documents? Can it be used to somehow canonicalize json?

    So far I like the commonly used approach in the Typescript community best:

    1. Create your Schema using https://zod.dev or https://github.com/sinclairzx81/typebox

    2. Generate your Types from the schema. It's very simple to create partial or composite types, e.g. UpdateModel, InsertModels, Arrays of them, etc.

    3. Most modern Frameworks have first class support for validation, like is a great example Fastify (with typebox). Just reuse your schema definition.

    That is very easy, obvious and effective.

    There's a ton of schema validators out there and most devs have their personal favorite. Mine was zod and is now typebox + ajv.
