Zod

Definitions

1. A TypeScript-first schema declaration and validation library that lets developers define a schema once and automatically infer the corresponding TypeScript type, providing runtime validation that stays in sync with compile-time types without code generation.

   In plain English: A JavaScript tool that checks incoming data matches the shape you expect and automatically creates the corresponding type definitions.

   Example: "We define the API request body as a Zod schema so we get both runtime validation and the TypeScript type from a single source of truth."
