What you'll learn

Your app has data bindings in the Home template.
Your app sends data from the Home to the HousingLocation.

Conceptual preview of Inputs

In this lesson, you'll continue the process of sharing data from the parent component to the child component by binding data to those properties in the template using property binding.

Property binding enables you to connect a variable to an Input in an Angular template. The data is then dynamically bound to the Input.

For a more in depth explanation, please refer to the Property binding guide.

<docs-workflow> <docs-step title="Update the `Home` template"> This step adds property binding to the `<app-housing-location>` tag.

In the code editor:

Navigate to src/app/home/home.ts
In the template property of the @Component decorator, update the code to match the code below: <docs-code language="angular-ts" header="Add housingLocation property binding" path="adev/src/content/tutorials/first-app/steps/07-dynamic-template-values/src/app/home/home.ts" visibleLines="[15,17]"/>

When adding a property binding to a component tag, we use the [attribute] = "value" syntax to notify Angular that the assigned value should be treated as a property from the component class and not a string value.

The value on the right-hand side is the name of the property from the Home.

</docs-step> <docs-step title="Confirm the code still works"> 1. Save your changes and confirm the app does not have any errors. 1. Correct any errors before you continue to the next step. </docs-step> </docs-workflow>

SUMMARY: In this lesson, you added a new property binding and passed in a reference to a class property. Now, the HousingLocation has access to data that it can use to customize the component's display.
