Bind the form in template using formGroup and formControlName.?

Short answer: ✅

Example code

this.profileForm = new FormGroup({ firstName: new FormControl('', Validators.required), lastName: new FormControl(''), email: new FormControl('', [Validators.required, Validators.email]) }); <form [formGroup]="profileForm" (ngSubmit)="onSubmit()"> <input formControlName="firstName" /> <input formControlName="lastName" /> <input formControlName="email" /> <button type="submit">Submit</button> </form>

Real-world example (ShopNest)

ShopNest’s ProductListComponent binds *ngFor to products and uses (click) to add to cart.
