Episode Notes

What this episode covers.

Once data is prepared by Sling Models, the final step is:
How is content actually rendered on the page?

That’s where HTL comes in.

In this video, I explain HTL (formerly known as Sightly) in Adobe Experience Manager (AEM) in simple terms:
• What HTL is and why it exists
• How HTL focuses on presentation, not logic
• Why AEM moved away from JSP
• How HTL improves security and maintainability

HTL is designed to keep templates simple and safe.
It ensures that business logic stays out of the presentation layer.

Understanding HTL completes the picture of how AEM renders content end-to-end.
