OpenAPI Validator

The IBM OpenAPI Validator lets you validate OpenAPI 3.0.x and OpenAPI 3.1.x documents for compliance with the OpenAPI specifications, as well as IBM-defined best practices.

Note: this page displays abbreviated usage info for getting started. Visit this page for the full documentation.

Installation

npm install -g ibm-openapi-validator

The -g flag installs the tool globally so that the validator can be run from anywhere in the file system. Alternatively, you can pass no flag or the --save-dev flag to add the validator as a dependency to your project and run it from your NPM scripts or JavaScript code.
