Join Justin Schwartzenberger for an in-depth discussion in this video Getting data to the component with input, part of Angular 2 Essential Training (2016).
- [Voiceover] You can define properties…for components you create…and make them available to be set…via the property binding syntax…by using an Angular decorator named Input.…Let's refactor the media item component…to move away from the static content…and support sending in a media item to display.…We start with the media-item.component.ts file…We need to import the input decorator to use it.…This comes from the angular2/core module bundle…and we already have an import statement for that.…The import statement support multiple import items…in the curly braces separated by commas…so we can add an input to the list.…
The input decorator is designed to be used…on a class property.…Let's create a new class property…on the media item component class…named MediaItem…and decorate it with the input decorator…placing the @input with the parentheses…in front of the property.…This will tell Angular that we want it to support…any property bindings…placed on instances of the media-item elements…where the property name is mediaItem.…
