Bug report: broken with ESM

[damianobarbati]

The generation of openapi.json is broken on node v14 and type=module:

$ yarn swagger-jsdoc -d openapi.js -o docs/openapi.json src/**/*.js
Error while loading definition file 'openapi.js':
Must use import to load ES Module: .../openapi.js
require() of ES modules is not supported.
require() of .../openapi.js from .../node_modules/swagger-jsdoc/src/utils.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename openapi.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from ...package.json.

Renaming to openapi.cjs as a workaround is broken nonetheless because swagger-jsdoc is expecting only js/json/yml extensions.

Hi @damianobarbati I spent an hour looking at sindresorhus/meta#15 and your bug report in order to try solving it. I haven't had the time to solve the issue fully, I tried something really quick and you can have a look and suggest further changes.
