Any idea about how primeNg(third-party library like Material) implements two way binding in their components because whenever I make a reusable component I have to provide values to the child using property binding and receive it in the child using @Input and if I want any data from the child I use @Output and receive it in the parent. But as seen in the primeNg reusable components, they can directly use two-way binding to provide and receive values.

You have to implement some of native functionality on your component. Like:

  1. Adding dynamic attribute
  2. Binding dynamic method (for change, key up, key down etc)
  3. Need to update the html as well. List is more I just mentioned some of basic steps.

Here you can read more about, your own two way binding.
