CRX DE Lite in AEM

 CRX DE Lite

CRX DE Lite is a web-based tool in Adobe Experience Manager (AEM) used for content and code management.

It is a lightweight version of the CRX (Content Repository Extreme) Development Environment (DE) and is designed for developers who need to work with the AEM repository, but do not require the full functionality of the CRX DE.

CRX DE Lite provides a user interface for performing various repository-related tasks such as browsing, creating, and editing nodes, properties, scripts and content. It also provides a console for executing code, debugging, and testing workflows.

When you go to http://localhost:4502/crx/de, below is the interface that opens up as a start up page

c.       /tmp/workflow: This folder contains the data and files that are generated during the execution of AEM workflows. AEM workflows are used to automate various content-related tasks such as publishing, review, and approval processes.

d.       /tmp/crx-repository: This folder contains the temporary data and files that are generated during the normal operation of the CRX repository, which is the underlying database that powers the AEM platform.

e.       /tmp/launcher: This folder contains the temporary files and data that are generated by the AEM launcher service, which is responsible for starting and stopping various AEM components and services.

6.       /var: This folder contains runtime data and logs for AEM. It includes information about requests, responses, and other system-level information.

a.       /var/clientlibs: This folder contains the client library files that are used to deliver CSS, JavaScript, and other assets to web pages and other digital experiences.

b.       /var/classes: This folder contains the compiled Java classes that are used by various AEM components and services.

b.       /conf/<component-name>: This folder contains the configuration data for a specific AEM component. The name of the folder corresponds to the name of the component for which the configuration data is being stored. For example, the /conf/acs-commons folder contains the configuration data for the ACS Commons component.

c.       /conf/<feature-name>: This folder contains the configuration data for a specific feature of the AEM platform. The name of the folder corresponds to the name of the feature for which the configuration data is being stored. For example, the /conf/global/settings/cloudconfigs folder contains the configuration data for the Cloud Services feature.

These folders play a critical role in organizing content and code within AEM. They allow for separation of concerns between applications, content, and system-level configurations, which makes it easier to manage and maintain the system over time. Developers and administrators can use these folders to manage custom code, create and edit content, and configure the system to meet their specific needs.
