A lifecycle hook that is called after Angular has fully initialized a component’s view. Define an ngAfterViewInit() method to handle any additional initialization tasks.
interface AfterViewInit {
ngAfterViewInit(): void;
}
ngAfterViewInit()
A callback method that is invoked immediately after Angular has completed initialization of a component’s view. It is invoked only once when the view is instantiated.
AfterViewInit starts to make more sense if you’ve began some dynamic component loading or manual view creation in Angular.
OnInit is called once when the component’s @Inputs and **@Outputs **have been resolved.
AfterViewInit is called when the component’s view has been attached. Remember that Angular compiles all to JS files, not html – the framework manages templates in code and has a rendering engine to interact with the DOM. Here, @ViewChild and @ViewChildren will be resolved.
