A walkthrough of the 3 algorithm choices a JSON-to-Valibot converter has to make differently from a JSON-to-Zod converter: optional wraps not chains, namespace import for tree-shake, and v.union as the only composition path.
Compare schema validation libraries on TypeScript inference, bundle size, performance, and DX. Zod's dominance, Valibot's lean approach, and where Yup still fits.
