By submitting your feedback, you accept the Adobe Terms of Use. Show Menu. Component Guidelines. The Core Components follow modern implementation patterns that are quite different from the foundation components.

This page explains these patterns, and when to use them to build your own authorable components. The first section General Component Patterns applies to any kind of component, while the second section Reusable Component Patterns applies to components that are intended to be reused across sites or projects, like the Core Components for instance.

General Component Patterns The guidelines in this section are recommended for any kind of component, regardless whether the component is specific to a single project, or whether the component is meant to be widely reused across sites or projects. Configurable Components Components can have dialogs with a variety of options. This should be leveraged to make components flexible and configurable, and avoid implementing multiple components that are mostly variations of each other. Typically, if a wireframe or design contains variations of similar elements, these variations should not be implemented as different components, but as the one component with options to choose between the variations.

To take this a step further, if components are reused across sites or projects, see the Pre-Configurable Capabilities section. Separation of Concerns Keeping the logic or model of a component separate from the markup template or view is usually a good practice. Sling Models are a set of Java annotations to easily access needed variables from POJOs, and therefore offer a simple, powerful, and efficient way to implement Java logic for components. It can call many forms of logic, which makes it very flexible.

Reusable Component Patterns The guidelines in this section can be used as well for any kind of component, but they make most sense for components that are intended to be reused across sites or projects, like the Core Components for instance. These guidelines can therefore be ignored for components that are only used on a single site or project. Pre-Configurable Capabilities In addition to the edit dialog that is used by page authors, components can also have a design dialog for template authors to pre-configure them.

The Template Editor allows to setup all these pre-configurations, which are called "Policies". To make components as reusable as possible, they should be provided with meaningful options to pre-configure.

This will allow to enable or to disable features of the components to match the specific needs of different sites. Proxy Component Pattern As each content resource has a sling:resourceType property that references the component to render it, it is usually good practice to have these properties pointing to site-specific components, instead of pointing to components that are shared by multiple sites.

This will offer more flexibility and avoid content refactoring if one site needs a different behavior for a component, because this customization can then be achieved on the site-specific component and won't affect the other sites.

However, for the project-specific components not to duplicate any code, they should each refer to the shared parent component with the sling:resourceSuperType property. These project-specific components that mostly just refer to parent components are called "proxy components". Proxy components can be entirely empty if they fully inherit the functionality, or they can redefine some aspects of the component.

Component Versioning Components should be kept fully compatible over time, yet sometimes changes that cannot be kept compatible are necessary. One solution to these opposing needs is to introduce component versioning by adding a number in their resource type path, and in the fully qualified Java class names of their implementations. This version number represents a major version as defined by semantic versioning guidelineswhich is incremented only for changes that are not backward-compatible.

Incompatible changes to the following aspects of components will result in a new version of them:. For further details, see the Versioning Policies document in GitHub. Component versioning creates a form of contract that is important for upgrades as it clarifies when something might need to be refactored. See also the section Upgrade Compatibility of Customizationswhich explains what considerations different forms of customizations require for an upgrade.

To avoid painful content migrations, it is important to never directly point to versioned components from content resources. As rule of thumb, a sling:resourceType of the content must never have a version number in it, or upgrading components will require the content to be refactored too.If they are used elsewhere such as in a wizard dialog for instancethey may not behave as expected.

This page provides the reference documentation or links to reference documentation required to develop new components for AEM. That document covers both the touch-enabled and classic UIs. Even if you do not need to use the classic settings in your new component it can help to be aware of them when inheriting from existing components. Depending on the component you want to implement it might be possible to extend or customize an existing instance, rather than defining and developing the entire structure from scratch.

When extending or customing an existing component or dialog, you can copy or replicate either the entire structure or the structure required for the dialog before making your changes.

Extending an existing component can be achieved with Resource Type Hierarchy and the related inheritance mechanisms. Note: Components can also be redefined with an overlay based on the search path logic.

Note: The content fragment component can also be customized and extended, though the full structure and relationships with Assets must be considered.

Versioned ClientLibs

It is also possible to override a component dialog using the Sling Resource Merger and defining the property sling:resourceSuperType. This is now recommended method for extending a component dialog. See the Sling Resource Merger for more details. Your component will be rendered with HTML.

Your component needs to define the HTML needed to take the required content and then render it as required, on both the author and publish environments. For web developers who need to build robust enterprise websites, HTL helps to achieve increased security and development efficiency. The mechanism to separate logic from appearance helps clarify what is called for a given view. It also allows differing logic for different views of the same resource.

This allows you to use Java code to implement the logic for selecting and configuring the component content. This allows you to use JavaScript code to implement the logic for selecting and configuring the component content. Organizing and optimizing the serving of this code can be a complicated issue. The client-side library system then takes care of producing the correct links in your final web page to load the correct code. You can configure the edit behavior of a component including attributes such as actions available for the component, characteristics of the inplace editor, and the listeners related to events on the component.

The configuration is common to both the touch-enabled and classic UI, albeit with certain, specific differences. The edit behavior of a component is configured by adding a cq:editConfig node of type cq:EditConfig below the component node of type cq:Component and by adding specific properties and child nodes. For components with a rendering that are sensitive to the WCM Mode, they need to be defined to refresh themselves specifically, then rely on the value of the cookie.

Dialogs are used to allow author to interact with the component. Granite UI provides a large range of the basic components widgets needed to create your dialog on the authoring environment. When necessary you can extend this selection and create your own widget. Customizing a dialog is similar to developing a component as the dialog is itself a component i. Note: If a component has no dialog defined for the touch-enabled UI, then the classic UI dialog is used as a fallback inside of a compatibility layer.

To customize such a dialog you need to customize the classic UI dialog. Note: See:. To create a new widget for use in a component dialog for the touch-enabled UI requires you to create a new Granite UI field component.

If you consider your dialog as a simple container for a form element, then you can also see the primary content of your dialog content as form fields.Assets provides for centralized video asset management where you can upload videos directly to Assets for auto-encoding to Scene7 and access Scene7 videos directly from Assets for page authoring. Scene7 video integration extends the reach of optimized video to all screens auto device and bandwidth detection.

Therefore, the out-of-the-box DAM ingestion workflow contains the following two ffmpeg-based workflow steps:. Be aware that enabling and configuring the Scene7 integration does not automatically remove or deactivate these two workflow steps from the out-of-the-box DAM ingestion workflow. If the answer is "yes" to either or both of these questions, then upload your video directly to Adobe DAM. If the answer is "no" to both questions, then upload your video directly to Scene7. The workflow for each scenario is described in the following section.

If you need a workflow or versioning for your assets, you should upload to Adobe DAM first. The following is the recommended workflow:. If you do not need a workflow or versioning for your assets, you should upload your assets to Scene7. Note: The Video tab does not appear if the page does not have a cloud configuration. Select the adaptive video encoding profile, an out-of-the-box single video encoding profile, or a custom video encoding profile.

Note: For more information about what the video presets mean, see the Scene7 documentation. Adobe recommends that you select either both adaptive video sets when configuring the universal presets or select the Adaptive Video Encoding option.

The selected encoding profiles are automatically applied to all videos uploaded to the CQ DAM target folder you set up for this Scene7 cloud configuration. You can set up multiple Scene7 cloud configurations with different target folders to apply different encoding profiles as needed. If you need to update the viewer and encoding presets for video in AEM because the presets have been updated in Scene7, navigate to the Scene7 configuration in the cloud configuration and click Update the viewer and encoding presets.

Click Upload to upload master video. Note: It may take some time for the video thumbnails to be generated. Dragging the DAM master video on to the video component accesses all of the Scene7 encoded proxy renditions for delivery. These components are not interchangeable. The Scene7 video component only works for Scene7 videos. The foundation component works with videos stored from AEM using ffmpeg and Scene7 videos.

Note: Out of the box, the S7 video component uses the universal video profile. Even if using the Scene7 video component is recommended for viewing Scene7 videos, this section describes using Scene7 videos with the Foundation Video Component in AEM, for the sake of completeness.

The following table provides a high level comparison of supported capabilties between the AEM Foundation Video component and the Scene7 Video component:. The various video encodings are created according to the S7 encoding presets selected in the S7 cloud config.

In order for the foundation video component to make use of them, a video profile must be created for each S7 encoding preset selected. This allows the video component to select the DAM renditions accordingly. Note: New video profiles and changes to them must be activated to publish. Create a new S7 Video Profile. In the NewDeveloping a robust digital strategy is both a challenge and an opportunity.

In AEM 6. Next, the core component structure and java structure are set up based on versions, i. Second, if new component versions are available, it allows for the individual migration of each component to the new version. Imagine you have all the content pages that are using Title component, and you want to upgrade to version two of Title component.

Instead, you can use a proxy component that points to a versioned component. All you need to do is to update the sling:resourceSuperType in proxy component to point to the new version component path. The implementation of Sling Models is bound to resource type, so if you need to customize the logic and change behavior for your component, you can create a custom component implementation that extends the same interface, and registers to the resource type of the proxy component.

See example below. Starting with 1. It separates the delivery of these foundational components from the application, so they can be continually enhanced and upgraded outside of the application lifecycle. It also accelerates the development process. What would you like to see next? More from this Author.

Images and videos are other better known ways of gaining cut-through in the SERPs for some search terms - check which are important for your industry. Ever since, marketers have always speculated user engagement as a possible ranking factor. This covers the average time on site, bounce rate, pogo sticking, and others. For conversion, it is a proven factor that determines the effectiveness of page elements that contribute to the chances of visitors committing to your call to action.

However, what makes this factors difficult to measure in search engines is the lack of data supporting it. User engagement is too indirect an influence on search rankings. Nonetheless, it is something that all website owners need to optimize if they are serious about getting more out of their SEO efforts. If the user finds the website beneficial, you can bet Google will as well. Heatmapping quickly comes to mind when thinking of user engagement.

The idea here is that the more clicks a page accumulates from its links, the more interaction it has with users. Tools like SumoMe Heat Maps and CrazyEgg are great ways to break down the number of clicks made by users on your tracked site pages. From here, you can see which links are clicked the most and least.

You can then optimize your site by improving your CTA links and buttons based on the accumulated data. To analyze visitor engagement with your site pages, the SumoMe Content Analytics is an extremely helpful tool in looking how many of your site visitors scroll down until the very end of the page.

Determine which elements of your site pages serve as obstacles that prevent visitors from scrolling down your page and optimize your site as you see fit.

The mobile market is big. So big, in fact, that Google is still figuring out how to provide mobile users with a better search experience. A faster loading site means more chances to retain visitors. While there is also interest in spending on mobile ads as the figures from eMarketer show, Google will soon take a more crucial role in delivering content to mobile users, starting with app store optimization.

Originally, apps are indexed on App Store and Google Play, not on Google search. Through App Index, apps are now indexed on Google search.
