Deprecated on Cloud Service

Replacing the HTL JavaScript Use API with Sling Models

Adobe lists the JavaScript Use API as deprecated, with the Java Use API as its replacement. Server-side JavaScript use objects are also slower and harder to test.

What to use instead

Sling Models (Java Use API) adapted from the request or resource.

How to fix it

1. Find data-sly-use attributes that load .js files.
2. Rewrite each use object as a Sling Model with unit tests.
3. Update the HTL to use the model class.

<div data-sly-use.teaser="teaser.js">${teaser.title}</div>

<div data-sly-use.teaser="com.acme.core.models.Teaser">${teaser.title}</div>

How we detect it

• Readiness scan rule js-use-api: HTL JavaScript Use API.
