Page specific clientlibs in AEM

  by @MukeshYadav_ 

Dear AEM Community,
I would like to share a useful solution for enabling page-level control over Client-Side Libraries (Clientlibs) in AEM.

Problem Overview:

AEM by default allows authors to manage Clientlibs at the template level and component level but there are cases where authors may need the same level of control at the page level. For example, when using JavaScript libraries like Vue.js or React or any micro-frontend module, it is inefficient to load these libraries globally for every page. Additionally, managing the order and placement of these Clientlibs for optimized DOM rendering  that is it should load the clientlibs in footer which is ideal for perfect DOM rendering and performance of the page

Solution Overview:

The solution involves creating a custom page properties that allows authors to control the Clientlibs at the page level without affecting other pages of the same templates.

Key Steps:

1. Create a Data Source for Clientlibs – A servlet to list all available Clientlibs and expose them as a data source that can be used in page properties.

2. Add Clientlibs to Page Properties – Modify the page dialog to include a dropdown field, allowing authors to select which Clientlibs which is fetch via Servlet create din step 1.

3. Fetch and Display Clientlibs in Page HTML– A Sling model is created to add the selected Clientlibsto the page htm and load them in the page’s footer(for js) or header(for css) for optimized DOM rendering.
