SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Zod provides a principled way to validate runtime data and derive strongly typed TypeScript definitions from schemas, ensuring data integrity across API boundaries and client-server boundaries.

Core Features & Use Cases

  • Schema declaration: Define robust runtime schemas with a rich set of primitives and complex nested structures.
  • Type inference: Automatically infer static TypeScript types from runtime schemas to keep code in sync.
  • Safe parsing: Validate inputs and API responses, producing typed results or detailed validation errors for UX-friendly error reporting.

Quick Start

Create a simple Zod schema and parse a sample payload to validate its shape.

FAQPage Schema
How do I validate runtime data and infer TypeScript types from API responses?

To validate runtime data and infer TypeScript types, declare a Zod schema to parse inputs, automatically deriving static types from the schema to keep your server and client code synchronized across API boundaries.

How does schema validation work for TypeScript projects across client and server boundaries?

Schema validation works by defining robust runtime schemas with primitives and complex nested structures, which parse incoming data to enforce runtime data structures and ensure data integrity across client and server boundaries.

Do I need the zod library to enforce input validation and type inference in TypeScript?

Yes, you need the zod library to parse and validate inputs, infer static TypeScript types, and generate safe, typed data shapes from runtime values for your TypeScript projects.

What's the best way to check API contract boundaries and report validation errors in TypeScript?

The best way to check API contracts is applying safe parsing with Zod schemas, which validates inputs and API responses to produce typed results or detailed validation errors for UX-friendly error reporting.

Why does type inference fail when parsing complex nested data structures at runtime?

Type inference can fail when the runtime schema declaration does not accurately match the complex nested data structures, preventing the automatic inference of static TypeScript types from the runtime values.

Can I use this approach to generate safe, typed data shapes from untrusted runtime values?

Yes, you can use Zod to parse untrusted runtime values, enforcing runtime data structures and automatically inferring static TypeScript types to generate safe, typed data shapes for your application.
