How do you handle validation in template-driven forms?

• Use built-in validators via HTML attributes like required, minlength.
• Use Angular directives like #username="ngModel" to check validity.

✅ Example:

<input name="email" ngModel required email #email="ngModel" />

<div *ngIf="email.invalid && email.touched">

<small *ngIf="email.errors?.required">Email is required</small>

<small *ngIf="email.errors?.email">Invalid email format</small>

</div>
