Integrating Lighting out Salesforce with AEM

1. Set Up a Lightning Out App in Salesforce

• Create a Lightning Out App:

  • In Salesforce, navigate to Setup and search for Lightning Components.
  • Develop a Lightning component that encapsulates the desired functionality.
  • Create a Lightning application that includes this component and is marked as ltng:allowGuestAccess="true" to permit external access.

• Enable CORS in Salesforce:

  • In Setup, search for CORS.
  • Add your AEM domain to the list of allowed origins to enable cross-origin requests.

2. Configure AEM to Host Salesforce Components

• Create an AEM Component:

  • Develop a custom AEM component that will host the Salesforce Lightning component.
  • Include a placeholder <div> in the component's HTML where the Lightning component will render.

• Include Salesforce Lightning Out Javascript:

  • In the AEM component's client library, include the Salesforce Lightning Out JavaScript file:
    html

    Copy code

    <script src="https://your-salesforce-instance.lightning.force.com/lightning/lightning.out.js"></script>

3. Initialize and Render the Lightning Component in AEM

• JavaScript Initialization:
  • In the AEM component's client library, add JavaScript to initialize and render the Lightning component:
    javascript

    Copy code

    $A.createComponent( "c:YourLightningComponent", {}, function(cmp) { cmp.set("v.attributeName", "value"); cmp.render(); } );

4. Handle Authentication and Security

• Salesforce Authentication:

  • Ensure that the Salesforce session is authenticated. This may involve setting up OAuth flows or using existing session cookies.

• AEM Configuration:

  • Configure AEM to allow the necessary scripts and handle any cross-origin resource sharing (CORS) issues.
