FAQPage Schema

How do I validate API payloads consistently across different schema libraries?▼

You can validate API payloads using Standard Schema-compatible schemas to ensure consistent data quality. The standardValidate function enforces a unified ValidationError shape across libraries like Zod, Valibot, and ArkType.

Can I use Standard Schema to unify error handling for async validation paths?▼

Yes, Standard Schema normalizes both synchronous and asynchronous validation paths for API workflows. This unification ensures you receive a single, consistent ValidationError type regardless of the validation timing.

What is the best way to check if an object is a Standard Schema schema?▼

You can use the isStandardSchema guard function to verify if an object conforms to the Standard Schema specification. This provides a clear, interoperable check before attempting validation.

How do I create a synchronous validator for Standard Schema inputs?▼

You can invoke createSyncStandardValidator to enforce validation on synchronous paths. This utility ensures your inputs adhere to the defined schema while returning a consistent error shape.

Does Standard Schema validation support Zod and Valibot?▼

Yes, Standard Schema validation supports interoperability across common schema libraries including Zod, Valibot, and ArkType. It standardizes the validation output into a single ValidationError type across these environments.
