swagger-client requires Node.js >=12.20.0 and uses different fetch implementation depending
on Node.js version.
>=12.20.0 <18- node-fetch@3>=18- native Node.js fetch
NOTE: swagger-client minimum Node.js runtime version aligns with Node.js Releases which means that we can drop support for EOL (End Of Life) Node.js versions without doing major version bump.
swagger-client works in the latest versions of Chrome, Safari, Firefox, and Edge
and uses native fetch implementation
provided by each supported browser.
