This page provides an overview of Adobe Experience Manager (AEM) components such as those used for page authoring.
What are Components? what-are-components
- Modular units which realize specific functionality to present your content on your website.
- Reusable.
- Developed as self-contained units within one folder of the repository.
- Have no hidden configuration files.
- They can contain other components.
- They can run anywhere within any AEM system and can also be limited to run under specific components.
- Have a standardized user interface.
- Have edit behavior that can be configured.
- Use dialog boxes that are built using subelements based on Granite UI components.
- They are developed using HTL.
- They can be developed to create customized components that extend the default functionality.
Because components are modular, you can:
- Develop a new component on your local instance.
- Deploy it to your test environment.
- Deploy it to your live authoring environment, where they allow authors and/or administrators to add and configure content.
- Deploy it to your live publish environments, where they are used to render content for visitors to your website.
Each AEM component:
- Is a resource type.
- Is a collection of scripts that completely realize a specific function.
- Can function in isolation, meaning either within AEM or a portal.
