ts-to-openapi

This package is not heavily maintained, and will be replaced with typeconv

This package converts TypeScript interfaces and types to OpenAPI/Swagger YAML.

It can detect what looks like GraphQL-to-TypeScript converted files, and clean them up (e.g. auto-expanding Scalar and Maybe).

The result is a set of schema components which can be referred to in OpenAPI/Swagger routes (or from other components).

Example

The following converts types MyTypeA and MyTypeB in my-file.ts into OpenAPI YAML and writes to stdout:

$> ts-to-openapi -f my-file.ts -t MyTypeA,MyTypeB
