.required('Email is required'),
password: Yup.string()
.min(5, 'Password must be at least 5 characters')
.required('Password is required')
});
return (
<Formik
initialValues={{ email: '', password: '' }}
validationSchema={validationSchema}
onSubmit={(values, { setSubmitting }) => {
setTimeout(() => {
alert(JSON.stringify(values, null, 2));
setSubmitting(false);
}, 400);
}}
>
{({ isSubmitting }) => (
<Form>
<Field type="email" name="email" />
<Field type="password" name="password" />
<button type="submit" disabled={isSubmitting}>

validation="required|email"
/>
<formulate-input
type="password"

myForm: FormGroup;
constructor(private fb: FormBuilder) {
this.myForm = this.fb.group({
email: ['', [Validators.required, Validators.email]],
password: ['', [Validators.required, Validators.minLength(5)]]
});
}
onSubmit() {
console.log(this.myForm.value);
}
}
