OpenAPI Nodegen

This package has been renamed, there will not be any new patches or fixes to this package.

The new package name and url: https://www.npmjs.com/package/generate-it

generate-it's version number will start on 5.1.0 in order to carry on from the original, meaning template checks and compatibility will still work.

The name change is due to the fact this package does not only support openapi.
