  • Inspect and traverse error trees produced by anyOf, oneOf, and not to surface root causes.
  • Flatten leaf errors and map them to form fields for UI validation messaging.
  • Convert error codes and paths into user-friendly messages, with support for path arrays and custom mappings.
  • Filter errors by code or include/exclude lists and build per-field error summaries.
  • Stop on first error if needed and leverage keyword information to categorize issues.

Quick Start

Validate data with ZSchema, catch the resulting ValidateError, and map the details to UI-friendly form errors.

FAQPage Schema
How do I convert z-schema validation errors into UI form feedback?

To convert z-schema validation errors into UI form feedback, you flatten leaf errors and map their JSON Pointer paths to form fields, transforming raw SchemaErrorDetail data into user-friendly messages for your application interface.

What is the best way to handle nested anyOf and oneOf validation errors?

Handling nested anyOf and oneOf validation errors requires inspecting and traversing the error tree to surface root causes, collecting leaf errors, and mapping them to specific form fields for actionable user feedback.

Can I filter z-schema errors by specific error codes?

Yes, you can filter z-schema errors by code or include/exclude lists, leveraging keyword information to categorize issues and build per-field error summaries for your application.

How do I map JSON Pointer paths from schema errors to form fields?

Mapping JSON Pointer paths from schema errors to form fields involves walking the error tree, collecting leaf errors, and converting the path arrays into form field identifiers for UI validation messaging.

Does this approach support stopping on the first validation error?

Yes, the approach supports stopping on the first validation error if needed, allowing you to immediately surface a single root cause issue to the user instead of processing the entire error tree.
