A custom schema for js-yaml (v1.0.0) that enables parsing and dumping of YAML CloudFormation templates using short-form intrinsic function syntax (e.g., !Ref, !Base64). It bridges YAML local tags to their JSON-compatible representation, ensuring parsed output matches JSON CloudFormation templates exactly. The package is stable but rarely updated, and is a fork of yyolk/cloudformation-js-yaml-schema with structural changes. Key differentiator: provides a ready-to-use schema that eliminates manual tag handling for AWS CloudFormation templates.
