Reliable I/O with the TypeScript Compiler API
summary
Generates fully typed HTTP clients from TypeScript Compiler API plus OpenAPI specs, claims to eliminate manual fetch functions and surface backend changes as compile errors, and runs generation in CI to publish up‑to‑date packages. Shows codegen of typed functions, React‑Query/SWR hooks and optional runtime validators (examples use React Query and Zod), demonstrates generating pages per endpoint and printing AST nodes to files, and reports that the generated clients integrate with server rendering and catch many bugs before runtime.
