Difference between template-driven and reactive forms in Angular

What are Forms in Angular?

In Angular there are two approaches to creating forms:

Template-driven forms — forms built based on templates (HTML).
Reactive forms — forms managed from TypeScript code.

Comparison Table

Characteristic	Template-driven Forms	Reactive Forms
Foundation	HTML template	TypeScript code
Module	`FormsModule`	`ReactiveFormsModule`
Management	Declarative (via template)	Imperative (via code)
Approach	Light, declarative	Flexible, programmatic
Validation	Via HTML attributes + directives	Via API and methods
Testing	More complex	Easier
Suitable for	Simple forms	Complex/dynamic forms

Template-driven Form Example

html

<form #userForm="ngForm" (ngSubmit)="onSubmit(userForm)">
  <input name="username" ngModel required />
  <input name="email" ngModel email />
  <button type="submit">Submit</button>
</form>

typescript

onSubmit(form: NgForm) {
  console.log(form.value);
}

Uses ngModel for data binding.
Directives (required, email) for validation.
Logic is in template.

Reactive Form Example

typescript

import { FormGroup, FormControl, Validators } from '@angular/forms';

form = new FormGroup({
  username: new FormControl('', Validators.required),
  email: new FormControl('', [Validators.required, Validators.email])
});

onSubmit() {
  console.log(this.form.value);
}

html

<form [formGroup]="form" (ngSubmit)="onSubmit()">
  <input formControlName="username" />
  <input formControlName="email" />
  <button type="submit">Submit</button>
</form>

Management completely in TS code.
Validation set in FormControl via Validators.
Better suited for complex scenarios.

When to Use?

Scenario	Recommended approach
Simple login form	`Template-driven`
Complex dynamic form with logic and validation	`Reactive`
Need for scaling and testing	`Reactive`
Quick and simple form implementation	`Template-driven`
Important: Both approaches can be combined, but better choose one and stick with it throughout project for consistency.
