Optional schema keys?

[spacesuitdiver]

Is it possible to have optional values in schema?

You can, but it's hacky. The RegExp check assumes values are strings, but missing values will be undefined. However, RegExp().test() does cast this to the string "undefined" so you can do something like: ^(foo|undefined)$.

I just ran into this as well and I'll open a PR to improve this.

@keithmorris I think this can be closed now #45 has been published.

This has been fixed as of release v2.9.0
