Lightning Component Facets

In this blog post, I am going to explain salesforce lightning facets. lighting facets are nothing but attributes of type Aura.Component[] with the array of attributes like body, title etc.To define your own facet, add an aura:attribute tag of type Aura.Component[] to your component. The body attribute has type Aura.Component[] .Now to start with I created a new lighting component with name AuraFacet.cmp with below code.

This is the component which will have two attribute types title and footer facets that are passed from the invoked component.Now I created a component name facetwrapper.cmp with the below code.



Now if you see the value of an attribute are passed by using the <aura:set> tag.Set tag is used to set the footer and body and title attributes from the wrapper component as shown below.
