OpenAPI to TypeScript
Generate TypeScript interfaces from OpenAPI schemas
ABOUT
What is OpenAPI to TypeScript?
Read the components.schemas section of an OpenAPI JSON document and generate TypeScript interfaces, aliases, enums, arrays, and references. The result is deliberately focused on data models rather than client generation.

FAQ
Questions, answered.
Does it generate an API client too?＋
No. It generates TypeScript data models from components.schemas. Use a dedicated generator when you need requests, hooks, or a fully typed client.
Which OpenAPI versions are supported?＋
The converter reads the shared schema shape used by OpenAPI 3 and Swagger 2 documents supplied as JSON.
Does it infer missing schemas from endpoint responses?＋
No. Schemas must be present under components.schemas or definitions.
