Proxy Components in AEM 6.4

What are proxy components?

Proxy Components are site-specific components which are inherited from core components, which define the desired component name and group to display for page authoring.

• Proxy Components refer to a Core Component as their super-type.
• Proxy Components follow the path  : /apps/my-site/components (Where core components path : core/wcm/components)

These site-specific components are called proxy components, for the reason they don't need to contain anything; they just serve mostly to define the version of a component to use for the site. Infact, when customizing the Core Components, these proxy components play an essential role for markup and logic customization.

Advantages of creating Proxy Components

• Proxy components helps categorization of components in a reusable way.
• Better seggregation: It is a good practice to have 'sling:resourceType' property pointing to site-specific components, instead of pointing to components that are shared by multiple sites.
• This provide more flexibility and avoid content refactoring if one site needs a different behavior for a component.
• Customization can then be achieved on the site-specific component and won't affect the other sites.
• Proxy components can be entirely empty if they fully inherit the functionality, or they can redefine some aspects of the component.
