Full framework for building client-side web applications

It automatically opens the app in a new browser tab

kebab-case with a custom prefix, such as app-item

It disables change detection for that component

It can be used directly without being declared in an NgModule

It forces the component to render only on the server

From the view back to the component class

A property or input on the target element or component

Each time the field's value changes as the user types

With a second @if using the negated condition only

It is only hidden with CSS but stays initialized

Its ngOnDestroy lifecycle hook is called and the component is destroyed

It is cached in memory and reused automatically

By a hash of the item's JSON representation

Angular falls back to tracking by index silently

It is a compile-time error, since track is mandatory

Prevents the link from being clicked twice

Applies the 'active' CSS class when that link's route is currently active

Forces the route to reload every time it's clicked

By injecting the Router service and calling its navigate() method

By changing the component's selector at runtime

In the providers array of the application config passed to bootstrapApplication

Nothing, the request fires automatically on return

Subscribe to it, or bind it in the template with the async pipe
