Using optionality and asynchronous rules in the same chain

[usernamus]

I would like to be able to write something like this chain of validations:

v8n().optional(v8n().email().checkEmailAvailable())

email – regular rule for email validation (pattern)
checkEmailAvailable – async rule

But right now it's not possible because inside optional rule we use .check strategy.

Is there a chance that this behavior can be implemented?

This should actually be fairly easy, it would probably require either an additional rule (asyncOptional?) or a parameter to the optional rule. Maybe there is a better solution than either of these, but those seem like the logical ones. @imbrn ?

Generally speaking this idea makes sense and should be implemented. Considering it's a new feature this one can be in 1.5.0.

So @usernamus, I've created #223. Is that what you were looking for?

[usernamus]

Wow. Thank you. This really seems to be what I need.

[sbarfurth]

Alright, barring review we can target this for the next release (which will be 1.5.0).

[sbarfurth]

Just FYI @usernamus, the next release will still contain this feature but it will be slightly different than #223 had it. The asynchronous validation will simply be supported on the optional rule when the testAsync strategy is used. This should be even simpler than adding a new rule. See #227.

@barfurth oh, that sounds great. Thanks you so much
