Angular – Pass Data from One Component to Another

This post shows how to pass data from one component to another in Angular using @Input. Also, we embed a component’s selector in another component’s HTML. Therefore, in that sense, we are passing data from a parent to a child component. We are not discussing URLs and redirects.

We have migrated the codes from Angular 7.20 to 15.0.0.

Angular Requirements

  • Angular CLI 15.0.4
  • NPM 8.19.2
  • Node 18.12.1
  • Internet connection
