Example Component Code

import { Component } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { isValidEmail, allowedOnlyKeyboardNumbers } from 'validator-package';

@Component({
  selector: 'app-my-form',
  templateUrl: './my-form.component.html'
})
export class MyFormComponent {
  myForm: FormGroup;

  constructor(private fb: FormBuilder) {
    this.myForm = this.fb.group({
      email: ['', [Validators.required, isValidEmail]],
      numberField: ['', allowedOnlyKeyboardNumbers]
    });
  }

  onSubmit() {
    if (this.myForm.valid) {
      console.log(this.myForm.value);
    }
  }
}
