remove-unused-components

Removes unused components from the bundle output.

In this context, "used" means that a component defined in the components object is referenced elsewhere in the API document with $ref.

API design principles

This decorator is intended to help security-focused enterprises prevent data leaks. Components can leak schemas, parameters, and other properties that may be unused in the exposed APIs, but used internally elsewhere.

However, your API document may contain common components used in other APIs. If that describes your use-case, please avoid using this decorator.

Configuration

Example of a configuration:

decorators:
  remove-unused-components: on
