Runtime validation for static types

Filter keys on runtypes to prevent additional properties

I said I want **SIMPLE** runtypes. Just functions that validate and return data. Combine them into complex types and TypeScript knows their structure. That's how runtypes work.

RunTypes devtools: cross-bundler plugin (Vite/Rollup/Rolldown/webpack/Rspack/esbuild) that rewrites RunTypes marker calls using the ts-runtypes resolver, plus an OXlint/ESLint lint plugin.

Generate runtypes from static types & JSON schema.

convert runtypes schemas to jsonschema

Sentinel marker + canonical reflection helper for ts-runtypes. The vite plugin rewrites every call of a function whose trailing parameter type is InjectRunTypeId<T> exported from this package.

Platform launcher for the ts-runtypes resolver binary. Resolves and execs the prebuilt native binary for the host platform; the binary itself rides as a per-platform optional dependency. Ships zero runtime dependencies.

Reusable adapter for Runtypes schemas

A code generator tool for Runtypes types

Integrate runtypes with property-based testing

Convert JSON into [runtypes](https://github.com/pelotom/runtypes/) capable of parsing the same JSON shape.
