Generating Types without climbing a tree
summary
Claim: generate TypeScript types and a minimal JS client straight from OpenAPI without manipulating the AST. Uses the tiny code-block-writer library and plain fetch, splits types and code so JavaScript builds stay dependency-free, and intentionally does no runtime validation on the client. Demo shows a generated client, build(url).getMovies()/createMovie(), compiles and runs against a local server, and replaces a slow TypeScript compiler API approach under a tight release deadline.
