This guide assists developers migrating validation logic from Zod v3 to Zod v4, consolidating patterns to avoid breaking changes and maintain consistency.
Update your Zod 3 schemas to Zod 4 by replacing old APIs with top-level validators (z.email, z.uuid, z.url) and adapting object schemas and error handling.

Migrating Zod schemas from v3 to v4 involves replacing old string validation APIs with top-level validators like z.email, z.uuid, and z.url, and updating object schemas and error handling to match Zod 4 APIs.
Top-level validators in Zod 4 include z.email, z.uuid, and z.url, which replace older string-based validation patterns to provide standardized runtime validation for common data formats.
Handle transformations and coercions in Zod 4 by utilizing updated preprocess and coercion APIs, ensuring refined error mapping compatible with Zod 4 style for consistent parsing results.
Zod 4 supports runtime validation for complex TypeScript data models including objects, arrays, and unions, using z.object for shapes and refinements for custom constraints.
The best way to update error handling during a Zod 4 migration is to adapt to its refined error mapping style, ensuring consistent error handling across validation pipelines and transformations.
