zod-v3

What problem does it solve?

Zod v3 完整 TypeScript schema 驗證參考。涵蓋所有 API、型別定義、程式碼範例。適用版本 zod ^3.x（本專案 ^3.24.2），不適用於 v4（v4 已發布 API 有顯著差異）。當程式碼涉及 zod、z.object、z.string、z.number、z.infer、ZodError、 safeParse、z.union、z.enum、z.discriminatedUnion、z.refine、z.transform、z.coerce、parseAsync、ZodType、z.nativeEnum、runtime validation 時，必須使用此 skill。Zod v4 已發布但本專案用 v3，API 不同。

Core Features & Use Cases

• Comprehensive API reference: literals, objects, arrays, unions, enums, records, maps, sets, discriminated unions, etc.
• Guidance on TypeScript inference, error handling, safeParse, parseAsync, and real-world validation patterns across API payloads, forms, and runtime data.
• Notes on v3 vs v4 differences and how to adapt existing codebases to v3 constraints.

Quick Start

Practice validating a sample payload with zod v3 to see real-time error messages and inferred types.
