Null type

[40thieves]

It'd be useful to have a null type. I'm using apiCheck for HTTP response testing (and it's great, thanks 😄) and some of my responses can be null.

Here's the custom type I'm using at the moment to work around it:

let nullType = (val, name, location) => {
  if (val !== null) return apiCheck.utils.getError(name, location, 'null')
}

Thanks for posting this issue. It's something I've been meaning to include. I have a few extra types that I think we need that I have in my own project. Like null, emptyObject, and range :-) If you have any other suggestions I'd love that.

👍 for all of those.

The only other thing I thought of was a shortcut for values which can have a type or can be null. Maybe nullable?

You've got everything you asked for and more in 7.1.0 :-) still gotta update the docs. But if you have any questions you can consult the tests!

Or, feel free to ask me of course :-)

Awesome! Thanks a lot 😄 I'm upgrading now.
