What problem does it solve?

Zod provides TypeScript-first schema validation patterns and best practices for writing robust schemas, annotations, and data validation.

Core Features & Use Cases

• Schema Annotations: Use .meta() and .describe() to attach metadata to schemas for UI hints and tooling.
• Type Inference & Validation: Leverage z.infer, z.object, z.string, z.number, and z.array for strong typing and runtime validation.
• API Guidance & Gotchas: Follow recommended chaining order; avoid mutating descriptions; handle object shapes and strict object mode.
• Examples: Annotate a user object with property-level metadata for UI forms.

Quick Start

Create a simple user schema and validate a sample payload, e.g., z.object({ name: z.string() }).parse({ name: "Amy" }).
