What problem does it solve?

This Skill automates the process of converting OpenAPI 3.0 specifications into TypeScript interfaces and type guards, streamlining the development of API clients and ensuring type safety.

Core Features & Use Cases

  • API Code Generation: Converts OpenAPI 3.0 JSON/YAML to TypeScript interfaces and type guards.
  • Type Safety: Generates type guards for runtime validation of API responses.
  • Documentation Integration: Preserves JSDoc comments from OpenAPI descriptions.
  • Use Case: Ideal for developers who need to create type-safe API interfaces from OpenAPI specifications.

Quick Start

Use the openapi-to-typescript skill to generate TypeScript code from your OpenAPI spec at './api/openapi.json'.

Frequently Asked Questions about openapi-to-typescript

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I generate TypeScript interfaces from an OpenAPI spec?▼

Yes, converting OpenAPI 3.0 YAML to TypeScript is fully supported. The tool processes both JSON and YAML specifications to generate TypeScript interfaces and type guards for runtime validation.

Does OpenAPI to TypeScript code generation preserve API descriptions?▼

Generating TypeScript type guards from OpenAPI adds runtime validation to your API responses. This ensures the data structures returned from your API client match the expected TypeScript interfaces dynamically.

Can I use openapi-generator for complex OpenAPI 3.0 TypeScript types?▼

You need an OpenAPI 3.0.x specification file in JSON or YAML format to use this Skill. Without a valid 3.0.x spec, the tool cannot generate the TypeScript interfaces and type guards.

What is the best way to automate TypeScript API client generation from OpenAPI?▼

The best way to automate TypeScript API client generation from OpenAPI is using a script that parses your 3.0.x spec. This automatically outputs type-safe interfaces and type guards without manual coding.
