Difference between Template-Driven Form and Reactive Form
Template-Driven Form (TDF) | Reactive Form | |
---|---|---|
Form model setup | Implicit in nature, as it relies on directives in the template to create and manipulate the underlying object model. | Explicit in nature, as it provides direct access to the underlying form’s object model. |
Logic handling | Form logic is mostly handled in the template. | Form logic is handled in the component. |
Data flow | Two-way data binding with NgModel directive provides asynchronous data update between view and model. | Data flow between view and model is synchronous in nature as each form element in the view is directly linked to the form model with the help of a FormControl instance. |
Form validation | Validations are done with the help of directives. | Validations are done with the help of functions. |
Unit testing | Tight coupling between the template and the component provides limited testability of form logic. | Separation of concern between the view and model provides better testability of form logic. |
Template Driven Form vs Reactive Form in Angular.
Angular provides two main approaches for creating forms: Template-Driven Forms and Reactive Forms. In this article, we’ll see both methods, highlighting their features, and providing code examples. We’ll also compare them side by side to help you understand when to use each.
