Zod 4 provides a robust, declarative way to validate data shapes in TypeScript applications, enabling runtime validation and safer type-safety across APIs, forms, and data pipelines.
Install the zod library in your project (npm install zod or yarn add zod). Create a simple schema using z.object to validate a basic payload, then run parse or safeParse and handle the result. Example: define a user payload schema and validate an input object, handling errors if validation fails.

To validate API payloads in TypeScript, define declarative schemas using Zod v4's API, then execute parse or safeParse to check inputs and handle runtime errors. This approach ensures type safety across forms and data pipelines.
Migrating from Zod 3 to Zod 4 requires updating schema definitions to the new API and adjusting error handling patterns. This Skill guides you through transitioning existing validation workflows for runtime checks.
Yes, Zod 4 supports schema composition for primitives, objects, arrays, enums, and unions. This enables precise runtime validation structures and automatic type inference within TypeScript applications.
In runtime validation, parse throws an error when validation fails, whereas safeParse returns a result object containing success status and error details. Zod 4 uses both methods to handle invalid data declaratively.
Yes, you must install the zod library in your project via npm or yarn before defining schemas. This dependency provides the declarative API required for runtime validation and type inference in TypeScript.
