      .required('Password is required')
      .min(5, 'Password must be at least 5 characters')
  });

  return (
    <Formik
      initialValues={{ username: '', password: '' }}
      validationSchema={validationSchema}
      onSubmit={(values, { setSubmitting }) => {
        setTimeout(() => {
          alert(JSON.stringify(values, null, 2));
          setSubmitting(false);
        }, 400);
      }}
    >
      {({ isSubmitting }) => (
        <Form>
          <Field type="text" name="username" />
          <ErrorMessage name="username" component="div" />
          <Field type="password" name="password" />

          <button type="submit" disabled={isSubmitting}>
            Submit
          </button>

      username: '',
      password: '',
      errors: {}
    };
  },
  methods: {
    validateUsername() {
      this.errors.username = validate(this.username, 'required');
    },
    validatePassword() {
      this.errors.password = validate(this.password, 'required|minLength:5');
    },
    submitForm() {
      this.validateUsername();
      this.validatePassword();
      if (!this.errors.username && !this.errors.password) {
        alert('Form submitted successfully!');

  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  form: FormGroup;

  constructor(private fb: FormBuilder) {
    this.form = this.fb.group({
      username: ['', [Validators.required]],
      password: ['', [Validators.required, Validators.minLength(5)]]
    });
  }

  onSubmit() {
    if (this.form.valid) {
      console.log('Form data:', this.form.value);
