Create your first AEM Component

 I'd be glad to guide you through creating your first component in Adobe Experience Manager (AEM):

Prerequisites:

  • Access to an AEM author instance.
  • Basic understanding of AEM's structure and terminology (components, dialogs, templates).

Steps:

  1. Project Setup (if applicable):

    • If you're working within a project, navigate to the appropriate location under /apps in CRXDE Lite (e.g., /apps/<your-project>).
    • If you're not using projects, create a new folder directly under /apps (e.g., /apps/my-components).

  2. Create the Component Node:

    • Right-click on the components folder (or your project folder) and select "Create" -> "Create Node..."
    • In the "Name" field, enter your desired component name (e.g., myComponent).
    • From the "Type" dropdown, select "cq:Component".
    • Click "OK" to create the component node.

  3. Define Component Properties:

    • Select the newly created component node.
    • In the property editor on the right, set the following properties (these are common, but you might need to adjust them based on your component's functionality):
      • jcr:title: A user-friendly title for the component (e.g., "My Simple Component").
      • sling:resourceSuperType: Set to "cq/Page" to inherit basic page functionalities.
      • componentGroup: Optionally, specify a group to categorize your component in the authoring UI (e.g., "My Components").

  4. Create the HTML Template (Sightly):

    • Right-click on the component node and select "Create" -> "File."
    • Name the file with a .html extension (e.g., myComponent.html).
    • Paste the following basic Sightly template code:
    HTML
    <html>
<head>
    <title>My First AEM Component</title>
</head>
<body>
    <h1>Hello from AEM!</h1>
</body>
</html>

  5. Optional: Create a Dialog (for Authoring Properties):

    • Right-click on the component node and select "Create" -> "Folder."
    • Name the folder _cq_dialog.
    • Inside the _cq_dialog folder, create a file named content.xml.
    • Define the dialog structure using the Granite UI components syntax (refer to AEM documentation for details). This will allow authors to configure properties of your component in the authoring UI.

  6. Save and Deploy (if using a development environment):

    • In CRXDE Lite, click the "Save All" button to persist your changes.
    • If you're developing in a local AEM instance, deploy your changes to the author instance using your preferred deployment method (e.g., package manager, Git integration).

  7. Use Your Component in Pages:

    • In the AEM authoring UI, navigate to the page where you want to use your component.
    • In Edit mode, drag and drop your component from the "Components" side panel onto the desired location on the page.
    • You can then configure any properties exposed through the dialog (if created).

Additional Considerations:

  • For more complex components, you might need to create additional folders and files within the component node, such as a _cq_template folder for defining the content structure and a _cq_editConfig.xml file for editing permissions.
  • Refer to the AEM documentation for in-depth information on component development, dialog configuration, and advanced features.

By following these steps, you'll have created a basic AEM component that can be used on your pages!

Create your first OSGI Configuration

  I'll provide a comprehensive explanation of OSGi configurations in AEM, their structure, and step-by-step instructions for creating your first one: OSGi Configurations in AEM In AEM, the Open Service Gateway Initiative (OSGi) framework plays a crucial role in managing the lifecycle of components (bundles). OSGi configurations are a mechanism for defining and managing configuration settings for various AEM components and services. These configurations can be used to: Store environment-specific settings (e.g., database connection details for development, testing, and production environments). Control component behavior by dynamically configuring properties. Enable feature flags for controlled rollouts of new features. Structure of an OSGi Configuration: OSGi configurations are typically stored in JSON format, using the .cfg.json extension. They reside within specific JCR nodes under the path /config . The basic structure consists of: pid (mandatory): A unique identifier for...
