kubb validate

Run kubb validate to check that a Swagger/OpenAPI document is valid without running the pipeline. Use it to catch errors early in CI or before you commit a spec change.

kubb validate -i ./petStore.yaml

$ kubb validate -i ./petStore.yaml✅ Validation success$ ▍

Usage

Validate a local OpenAPI file:

Terminal

kubb validate -i ./petStore.yaml

Validate a remote document:

Terminal

kubb validate -i https://petstore3.swagger.io/api/v3/openapi.json

Options

Option	Default	Required	Description
--input=<path>, -i <path>		true	Path or URL to the Swagger/OpenAPI document to validate.

TIP

kubb validate exits with a non-zero status code when the spec is invalid. Use it as a pre-commit hook or CI step to fail the build.
