This skill provides practical patterns and guidance for validating data with Zod v4, helping developers enforce consistent data contracts and simplify migration from Zod v3.
Install the zod package and import { z } from 'zod'. Create a basic schema: z.object({ id: z.string(), email: z.string().email() }). Validate a data object with schema.parse(data) and handle validation errors.

Validate API payloads by defining a Zod 4 object schema and passing incoming data to schema.parse(data). It enforces type-safe data contracts for primitives, objects, arrays, and unions while returning structured errors for invalid input.
Zod 4 migration involves updating schema patterns and adjusting syntax for primitives, objects, and transformations. This skill provides specific guidance and tips for migrating existing Zod 3 schemas to enforce consistent data contracts in v4.
Yes, Zod 4 integrates with React Hook Form for form validation. You define schemas using primitives, objects, and refinements, then connect the schema resolver to validate user inputs and handle errors directly in the form.
Handle transformations and default values in Zod 4 by applying transformation patterns directly to primitive and object schemas. This ensures data undergoes type-safe modifications and falls back to default values during parsing.
You need the zod package version 4 and a JavaScript or TypeScript runtime environment. No other dependencies are required to start creating schemas, parsing data, and handling validation errors.
Schema parsing fails when input data violates the defined Zod 4 data contracts. You can catch these validation errors using error handling patterns to identify mismatched primitives, objects, arrays, or unions in the payload.
