Angular Form Types:

  • Template Driven Forms
  • Reactive Forms (Dynamic Forms)

Angular Template Driven Form:

  • Easy to use
  • Template driven forms are simple and straightforward
  • All the validations, form elements are all defined in the template file
  • We will need to import FormsModule in app module to work with template driven forms

Angular Reactive/Dynamic Form:

  • All the form elements, user interactions and validations are handled in the component class.
  • We will make use of angular built in formGroup and formControl.
  • Can control better data binding.
  • Exclusive define custom regular expression patterns of error handling.
  • We will need to import ReactiveFormsModule in our app module.
  • Very flexible and allows users to define, develop complex requirements of forms.
  • More logic in the component class and less in HTML mark up itself.
