const { userConfigDir } = os;
Returns the default root directory to use for user-specific configuration data. Users should create their own application-specific subdirectory within this one and use that.
On Unix systems, it returns $XDG_CONFIG_HOME as specified by https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html if non-empty, else $HOME/.config. On Darwin, it returns $HOME/Library/Application Support. On Windows, it returns %AppData%.
If the location cannot be determined (for example, $HOME is not defined), then it will throw an error.
