ng-validators's Issues

Feature ideas

Hey Moebius, Awesome repo here. I've bene on the hunt for a really well written and documented collection of custom validators for Angular 2+. Are you interested in growing this repo? I would be willing to commit all my custom validators if so.

I'm looking for alpha characters only and numeric characters only validators for name fields.

Something like this for alpha only:

import { FormControl } from '@angular/forms';

export class AlphaOnlyValidator {
    static invalidAlphaOnly(control: FormControl): { [key: string]: boolean } {
        if (control.value.length && !control.value.match(/^[a-z]+$/i)) {
            return { invalidAlphaNumeric: true };
        }
        return null;
    }
}

Cause Angular AoT build errors

Hi,

This plugin cause an "AoT build failed" error when compiling a project in production mode.
Output of error :

`typescript error:
Error encountered resolving symbol values statically. Calling function 'ɵmakeDecorator', function calls are not supported. Consider replacing the function or lambda with a reference to an exported function,
resolving symbol Injectable in path_to_project/node_modules/@moebius/ng-validators/node_modules/@angular/core/core.d.ts,
resolving symbol ɵi in path_to_project/node_modules/@moebius/ng-validators/node_modules/@angular/forms/forms.d.ts,
resolving symbol ɵi in path_to_project/node_modules/@moebius/ng-validators/node_modules/@angular/forms/forms.d.ts

Error: The Angular AoT build failed.`

Your plugin seems to not been compatible with Angular AoT,

Thank you

Expected validator to return Promise or Observable.

I am getting this error on Angular 4+

Expected validator to return Promise or Observable.

Using like this:
this.newPasswordForm = this.formBuilder.group({ password: ['', [Validators.required, Validators.minLength(6)]], password2: ['', [Validators.required, matchOtherValidator("password")]] });
