    Json Schema Type Builder with Static Type Resolution for TypeScript

    • - Is currently (afaik) the fastest JIT validator for JavaScript

    TypeBox is zero dependency and sits around 5kb minified. The library is heavily tested for JSON schema compliance through Ajv and can be embedded in most JavaScript applications that standardize on the JSON schema specification. It gets around 20 million monthly downloads via NPM (as it's taken as a dependency on some very popular packages), but still seems relatively unknown to the TypeScript ecosystem at large.

    Just wanted to share and shine a bit more of a light on this library.

    Here's a few links to some of it's benchmarks
