Option to determine presence of a config file? about configstore

[sindresorhus]

Why do you need that? What’s your use-case?

I need to access a configstore file but it must pre exist. Simply using this:
const confdef = new Configstore('rest_default') will automatically create the file if it doesn't exist. I don't want that. I need to only open the configstore file if it first exists otherwise I will put out an error.

I believe that it would be useful to be able to determine the existence or not of a config file.
My initial thought was to issue this:
const confdef = new Configstore('profile_default')
let x = conf.get('parm')
and then check if x was undefined.
If undefined it would tell me that the config file had been created and didn't preexist. That is really cludgy.
The follow-on problem is that there is no means to go and delete that newly created config file.
So 2 problems -

1. unable to check for the existence of a configstore file
2. unable to subsequently delete a configstore file

Might it be possible to add a couple of methods to provide the 2 requests above?
I know you also authored 'conf' and would move to that if necessary but it seems to have the same 2 limitations.

const confdef = new Configstore('rest_default') will automatically create the file if it doesn't exist.

Actually, it won't. Only if you use the defaults option. See: b8d6372

1. We could expose a property for whether it's setting up the config for the first time (meaning there was no config file already). Would that solve your problem? You would need to come up with a good name for the property.
2. We could add a .removeConfigFile(). Could be useful for uninstall/cleanup scenarios. What's your use-case for this?
