Top 3 TypeScript Checker Projects

  1. typia

    Super-fast/easy runtime validators and serializers via transformation

    Project mention: Node.js can now execute TypeScript files | news.ycombinator.com | 2025-08-17

    Yeah, but Zod and all of the runtime schema libraries all kind of add verbosity to the type system compared to say something like Typia[0] which AOT compiles the type checks (and ends up being way more elegant).

    Caveat is that there are some restrictions with the compiler and some possible footguns (duplicated declarations bloating code).
