Generate TypeScript types and JSON Schema
When you receive a sample API response and need both a TypeScript type for the frontend and a JSON Schema for runtime validation, this chain generates both from the same source. The first node produces TS interfaces; the second node produces a JSON Schema. Keep both outputs in sync to avoid drift between compile-time and runtime checks.
What it solves
Derive TypeScript interfaces and a JSON Schema from a sample JSON for end-to-end type safety.
Input → Output
JSON to TypeScript input → JSON to TypeScript output across 1 step.

Sample input
{"id":1,"name":"Alice","email":"[email protected]"} Expected output
interface Result {
id: number;
name: string;
email: string;
} This pair is executed against the real tools at build time (tests/unit/recipes.test.ts) — the expected output is verified, not illustrative.
