The reactive approach of creating forms in Angular is where the form validation logic is passed to the ViewModel. The work of any frontend developer could have been much easier if the user gives the correct input in the form, but unfortunately, it’s not possible. Hence Reactive forms come into the picture here. 

The form fields are put in the ViewModel and have a 2-way binding by default. Also, since the validation logic is done on the ViewModel, the template is less complex.

You can implement many factors when it comes to Reactive Forms, some of them are:

  • User’s Name, Email and Confirm inputs
  • Required validation on all inputs
  • Show required validation errors
  • Disabling the submit option until it is valid
  • Submit function 

Let’s take an example of creating a Reactive form for registering a new user in an Angular framework. Here is the link for more information on the Reactive form and it’s implementation
