Tutorial

The Hero Editor

Let’s take stock of what we’ve built.

  • Our Tour of Heroes uses the double curly braces of interpolation (a kind of one-way data binding) to display the application title and properties of a Hero object.
  • We wrote a multi-line template using ES2015’s template strings to make our template readable.
  • We can both display and change the hero’s name after adding a two-way data binding to the <input> element using the built-in ngModel directive.
  • The ngModel directive also propagates changes to every other binding of the hero.name.

Master/Detail

Here’s what we achieved in this chapter:

  • Our Tour of Heroes now displays a list of selectable heroes
  • We added the ability to select a hero and show the hero’s details
  • We learned how to use the built-in directives ngIf and ngFor in a component’s template


Multiple Components

Let’s take stock of what we’ve built.

  • We created a reusable component
  • We learned how to make a component accept input
  • We learned to declare the application directives we need in an Angular module. We list the directives in the NgModule * decorator's declarations array.
  • We learned to bind a parent component to a child component.
