The best practice for customizing core Adobe Experience Manager (AEM) components is tooverlaythem under the /apps directory, rather than directly modifying the components in /libs. By overlaying the core component in /apps//components/, developers can extend and customize core components while keeping the original intact. This approach ensures that customizationsare preserved during AEM updates and align with AEM’s best practices for maintainability and upgradability.
Key Benefits of Overlaying Components in /apps:
Preservation of Core Components:By overlaying, the original core component in /libs remains unaltered, which prevents issues during AEM updates as overlays in /apps are not overwritten.
Customization and Flexibility:Overlays allow developers to extend or modify core components to meet specific project needs without impacting the standard AEM components.
Best Practice for Maintainability:Customizing components under /apps aligns with AEM’s recommended practices for ensuring that the project remains compatible with future updates and upgrades.
Adobe Experience Manager References:
Adobe’s documentation on component development emphasizes the importance of using overlays in /apps for customizations. This approach helps maintain a clear separation between core components and custom implementations, supporting a sustainable and maintainable AEM architecture.
