openapi-typescript

What problem does it solve?

This Skill ensures your API clients and server code are always in sync with your OpenAPI specification, preventing runtime errors and improving developer confidence.

Core Features & Use Cases

• Type Generation: Automatically generate TypeScript types from OpenAPI 3.x or Swagger 2.0 specs.
• Type-Safe Clients: Use openapi-fetch to create clients that infer request/response types directly from generated schemas.
• Runtime Validation: Integrate with Zod or TypeBox to validate API responses at runtime, bridging the gap between compile-time and runtime safety.
• Use Case: Automatically generate all frontend API types from your backend's OpenAPI spec, ensuring that UI components consuming the API always have accurate type information, and catch breaking changes in CI.

Quick Start

Use the openapi-typescript skill to generate type definitions from the 'openapi.yaml' file in the current directory.
