Transforming an OpenAPi v3 spec

transform.js

// small transformation utility to modify an openApi spec
// tested against: https://github.com/ringcentral/ringcentral-api-specifications/blob/master/ringcentral.spec.2019110220191017-1140.openapi3.yaml

const yaml = require('js-yaml');
const fs = require('fs');
const condition = 'x-auth-required';
const filename = 'ringcentral.spec.openapi3.yaml';

// Transformation function
function transform(spec) {
    for (const path in spec.paths) {
        const pathItem = spec.paths[path];
        for (const method in pathItem) {
            const methodItem = pathItem[method];
            if (methodItem[condition] === false) {
                methodItem.security = [{}]
                console.log(path, method, methodItem);
            }
        }
    }
}

// Get document, or throw exception on error
const rawSpec = yaml.safeLoad(fs.readFileSync(filename, 'utf8'));
const transformedSpec = transform(rawSpec);

// and now use the spec in fastify openapi glue or write it 
// to a JSON or YAML file and use that
