Workflow Launchers Skill — AEM as a Cloud Service

Purpose

This skill teaches you how to configure and deploy Workflow Launchers that automatically start workflows in response to JCR content changes on AEM as a Cloud Service.

When to Use This Skill

• A workflow must start automatically when an asset is uploaded to DAM
• A review workflow should trigger whenever an author modifies content under a specific path
• You need to replicate or replace an OOTB launcher behavior without editing /libs
• You want to enable, disable, or restrict a launcher to specific run modes

Core Concept: What Is a Workflow Launcher?

A Workflow Launcher (cq:WorkflowLauncher) is a JCR node that registers a JCR event listener. When a node event occurs at a path matching the launcher's glob pattern, node type, and conditions, the Granite Workflow Engine enqueues a workflow start.

The listener is managed by WorkflowLauncherListener (an OSGi service). It reads all active launcher configurations at startup and re-evaluates them when configurations change.
