What problem does it solve?
This Skill provides comprehensive guidance for using Zod, a TypeScript-first schema declaration and validation library, to ensure type safety, efficient parsing, and robust error handling.
Core Features & Use Cases
- Schema Definition: Offers rules for selecting appropriate schema types, avoiding unnecessary optional fields, and leveraging coercion for form data.
- Parsing & Validation: Provides guidelines for safe parsing with
safeParse(), handling all validation issues, and validating at system boundaries.
- Type Inference: Covers best practices for using
z.infer() and enabling TypeScript strict mode for reliable type inference.
- Error Handling: Delivers advice on customizing error messages, internationalization, and effective form error display.
- Object Schemas: Details strategies for using
strict(), strip(), partial(), pick(), omit(), and extend() for object schema management.
- Schema Composition: Discusses reusability of schemas through shared modules, intersection types, and lazy loading for recursive schemas.
- Refinements & Transforms: Explains the use of
refine(), superRefine(), transform(), coerce(), and catch() for custom validation and data coercion.
- Performance & Bundle: Suggests performance optimizations like caching, using Zod Mini, lazy loading large schemas, and optimizing array validation.
