SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Zod provides a cohesive, type-safe way to validate and parse runtime data in TypeScript projects, reducing runtime errors and ensuring data contracts are enforced at the boundary between systems.

Core Features & Use Cases

  • Type-safe schemas for primitives and objects (e.g., z.string(), z.number(), z.object({...})).
  • Parse and SafeParse to get typed results without throwing.
  • Transform, refine, and nested schemas to build robust validation pipelines and enforce business rules.

Quick Start

Install zod in your project and define a basic schema, then validate a sample payload with parse or safeParse.

FAQPage Schema
How do I validate runtime data in TypeScript without throwing errors?

You can validate runtime data in TypeScript without throwing errors by using safeParse instead of parse. This returns a typed success or failure result, allowing you to handle invalid data gracefully at API boundaries.

What is the best way to enforce API contracts and type safety in TypeScript?

The best way to enforce API contracts is using Zod schemas to parse incoming payloads. This ensures type-safe runtime validation across frontend and backend workflows by catching invalid data before it enters your systems.

How do I add custom business rules to TypeScript schema validation?

You can add custom business rules to TypeScript schema validation by using the refine function. This allows you to build robust validation pipelines that enforce complex logic beyond standard primitive type checks.

Can I transform data types during TypeScript runtime validation?

Yes, you can transform data types during TypeScript runtime validation by using the transform feature. This enables you to parse input data and output it as a different type while maintaining strict type inference.

Does this runtime validation approach work with nested objects and unions?

Yes, this runtime validation approach works with nested objects and unions. You can define complex schemas using z.object and union types to parse varied data structures reliably across frontend and backend boundaries.
