RHOAS Spectral Ruleset

A custom ruleset for Spectral following the RHOAS API Guidelines.

Using

npm is required to use Spectral.

To use this Spectral ruleset add the following to your .spectral.yaml:

extends: 'node_modules/@rhoas/spectral-ruleset/dist/ruleset.yaml'

Alternatively you need to create new ruleset

echo 'extends: node_modules/@rhoas/spectral-ruleset/dist/ruleset.yaml' > .spectral.yaml

Run the Spectral CLI with yarn:

yarn add @rhoas/spectral-ruleset
yarn spectral lint ./path/to/openapi.yaml

or npm:

npm i -g @rhoas/spectral-ruleset
spectral lint ./path/to/openapi.yaml

Rules

The RHOAS ruleset extends the Spectral built-in "oas" ruleset (except operation-tags, openapi-tags). You can see the full list of rules from that ruleset here
