Zod 是 TypeScript 生态最流行的运行时验证库，本文从基础 Schema 到高级用法全面讲解。
Zod is the most popular runtime validation library in the TypeScript ecosystem.
TypeScript 的类型只在编译时TypeScript 类型在编译后就消失了，运行时收到的 API 数据、用户输入都可能不符合类型定义。Zod 填补了这个空白。基础用法import { z } from "zod" const UserSchema = z.object({ name: z.string().min(2).max(50), email: z.string().email(), age: z.number().int().positive().optional(), }) type User = z.infer<typeof UserSchema> const result = UserSchema.safeParse(input) if (result.success) { console.log(result.data) // 类型安全的 User } else { console.log(result.error.issues) }高级特性transform：验证的同时转换数据discriminatedUnion：类型安全的联合类型与 tRPC / React Hook Form 集成
Runtime Type SafetyTypeScript types disappear at runtime. Zod provides schema-based validation with type inference, transforms, and integration with tRPC and React Hook Form.
