Get all validation errors for Angular FormGroup

get-form-validation-errors.ts

import { FormGroup, ValidationErrors } from '@angular/forms';

export function getFormValidationErrors(form: FormGroup) {

  const result = [];
  Object.keys(form.controls).forEach(key => {

    const controlErrors: ValidationErrors = form.get(key).errors;
    if (controlErrors) {
      Object.keys(controlErrors).forEach(keyError => {
        result.push({
          'control': key,
          'error': keyError,
          'value': controlErrors[keyError]
        });
      });
    }
  });

  return result;
}

Useful, thanks !

This is the best. I have so many nested components it's a pain to hunt down errors.
