OpenAPI type generator

Generate types from OpenAPI v3 documentation (json or yaml) with single command

npx @kallinen/openapi-typings-gen openapi.json > openapi-types.d.ts

The library supports also methods that don't have operationId set by adding -k as argument

npx @kallinen/openapi-typings-gen -k -i openapi.json -o openapi-types.d.ts

Zod Validation

You can generate Zod validation schemas along with TypeScript types by using the -z or --zod flag:

npx @kallinen/openapi-typings-gen -z -i openapi.json -o openapi-types.d.ts

⚠️ This feature is experimental and may change in future releases.
