super-detype

Super-detype is a CLI tool (v2.2.2) that converts an entire TypeScript project to JavaScript by stripping type annotations and compiling with Babel. It handles Node.js, React, Next.js, Remix, and Vite projects, but not Vue or Svelte. Unlike file-by-file converters or copy-paste tools, it processes whole directories at once. It requires Node >=22 and is primarily used via npx or global install. Release cadence is sporadic. Ships bundled TypeScript types for its own API but the tool itself generates JS.
