The extends configuration entry allows your project configuration to extend an existing configuration set. Multiple values are supported, and can include:

Extends is useful if you use a common ruleset across multiple projects. Define a ruleset in one location, and each project can extend it, with or without modification.

Default ruleset: recommended

If there is no redocly.yaml configuration file, the recommended ruleset is used by default.


The extends configuration is an array of strings.

The array is parsed in the order it is defined, so the later entries in the array overwrite the earlier ones.


To get started, try the following example to configure your project to be based on the minimal ruleset:

 - minimal
  • apis configuration options allow setting per-API configuration in redocly.yaml.
  • rules settings define the linting rules that are used.
