Hey API OpenAPI to TypeScript

Use when the task mentions Hey API, heyapi.dev, @hey-api/openapi-ts, or converting an OpenAPI spec into TypeScript types, SDKs, or validators.

Default workflow

1. Confirm the source spec location: local file, URL, or hosted registry reference.
2. Start with the smallest working generation path:

npx @hey-api/openapi-ts -i openapi.yaml -o src/client

3. If the project will keep generated code in source control or regenerate often, install the package and move to a config file.
4. Regenerate instead of hand-editing generated files.
