Join Justin Schwartzenberger for an in-depth discussion in this video Components, Bootstrap, and the DOM, part of Angular 2 Essential Training.
- [Instructor] Angular is built upon components.…The starting point of an Angular app…is the bootstrapping of the initial parent component.…Much like the html DOM tree…that starts with an html element…and then branches down from there,…Angular runs on a component tree model.…After Angular loads the first component…with the bootstrap call,…it then looks within that component's html view…and sees if it has any nested components.…If so, Angular finds matches…and runs the appropriate component code on those.…This repeats for each component down the tree.…
A component in Angular is used to render a portion of html…and provide functionality to that portion.…It does this through a component class…in which you can define application logic for the component.…For example, you can have a MediaItemComponent…that can have a property named mediaItem…that represents the data for a media item.…And that component can also have a method…called onDeleteClick that could handle…raising the delete media item event.…With each component in Angular,…
