INodePackageJson.typesVersions property​

A table of TypeScript *.d.ts file paths that are compatible with specific TypeScript version selectors. This data take a form similar to that of the INodePackageJson.exports field, with fallbacks listed in order in the value array for example:

"typesVersions": {
  ">=3.1": {
    "*": ["./types-3.1/*", "./types-3.1-fallback/*"]
  },
  ">=3.0": {
    "*": ["./types-legacy/*"]
  }
}

or

"typesVersions": {
  ">=3.1": {
    "app/*": ["./app/types-3.1/*"],
    "lib/*": ["./lib/types-3.1/*"]
  },
  ">=3.0": {
    "app/*": ["./app/types-legacy/*"],
    "lib/*": ["./lib/types-legacy/*"]
  }
}

See the TypeScript documentation for details.
