Forms & Validation
Angular Forms Overview
Angular offers two form systems. Template-driven forms declare the model in the template with ngModel and suit simple cases. Reactive forms build the model in TypeScript with FormGroup and FormControl and are the recommended choice for anything real.

Key points to remember
- Both are fully supported — choose one per form, never mix them on the same control.
- Reactive forms are synchronous and predictable, which makes them easier to debug.
- Angular 14 added typed forms, so control values are properly typed.
Template-driven vs reactive forms
| Template-driven | Reactive | |
|---|---|---|
| Model lives in | the template | the component class |
| Module to import | FormsModule | ReactiveFormsModule |
| Validation | HTML-style directives | validator functions in TypeScript |
| Dynamic fields | awkward | straightforward |
| Unit testing | needs the DOM | test the model directly |
| Best for | login, small forms | multi-step, dynamic, validated forms |
