Decorators are a way of changing an API description during bundling. This updating during bundling can be useful for the following use cases:

  • removing some endpoints from an OpenAPI description before publishing
  • updating description fields
  • adding extra elements, such as examples, or metadata for other tools to use

To learn how to configure decorators, read more about their configuration syntax.

List of decorators

Some common decorator use cases are already built in to Redocly. Check the list below for the decorators you can use immediately.

Decorator configuration syntax

The following example shows how to configure a decorator in the Redocly configuration file.

    root: ./openapi/openapi.yaml
        decorator-option: example-value
    decorator-option: example-value

Optionally, you may specify severity as one of decorator options in the configuration. Severity can be set to error, warn or off, similar to how it works with rules. When it's specified, any problem reported from the decorator is treated according to the configured severity. Setting severity: off disables the decorator altogether. Generally, it's not necessary to specify severity for decorator configuration except for troubleshooting purposes.

Custom decorators

If you don't see the decorator you need, you can create your own decorators using custom plugins.
