Ionic 4 Asynchronous Validator that works?

#1

Does anyone have an example of an Asynchonous custom validator using a http call that actually works?

I have tried adapting this to Ionic, but I can’t figure out how to get it to work in Ionic 4…

Ditto with Joshua Morony’s tutorial, I can’t get it to work with an http call…

…any help appreciated!

I managed to find a way to get Async Validators to work in Ionic 4 and have posted a tutorial…
