VALIDATION-runtime-checks

What problem does it solve?

TypeScript's compile-time types are erased at runtime, leaving external data (APIs, JSON, user input) unvalidated and prone to runtime errors. This Skill bridges that gap, ensuring data integrity and type safety.

Core Features & Use Cases

• Define Schemas: Create robust schemas using Zod to describe the expected shape and types of your data.
• Extract TypeScript Types: Automatically derive TypeScript types from your Zod schemas, ensuring consistency between validation and types.
• Validate at Runtime: Perform runtime checks on incoming data, catching inconsistencies before they cause crashes.
• Handle Validation Errors: Gracefully manage and report validation failures with user-friendly messages.
• Use Case: Validate an API response for user data using Zod, ensuring all fields (e.g., id, name, email, age) match the expected schema before processing, preventing runtime crashes from malformed data.

Quick Start

Define a Zod schema for a Product interface with id, name, and price fields, then use it to validate an unknown JSON object.
