An AEM Developer should add a front-end dependency in the package.json file. The package.json file is a standard configuration file for managing dependencies in JavaScript projects, including those using npm or Yarn as package managers.

Here’s how to add a front-end dependency:

Open the package.json File: This file is typically located at the root of your project.

Add the Dependency: Add the required front-end dependency under the dependencies or devDependencies section. For example, to add lodash as a dependency:

{

"name": "my-aem-project",

"version": "1.0.0",

"dependencies": {

"lodash": "^4.17.21"

}

}

Install the Dependency: Run the following command to install the new dependency:

npm install

Verify Installation: Ensure that the dependency has been added to the node_modules directory and is listed in the package-lock.json file.

The package.json file is the central place to manage all front-end dependencies, making it easy to track, update, and share dependencies across the development team.

Managing Dependencies in AEM Projects

These steps ensure that the front-end dependencies are managed efficiently and consistently within the AEM project.

AEM SPA integration provides various design models for different levels of authoring capabilities and developer control. In the design model where AEM is used as a headless CMS without using the SPA Editor SDK framework, the developer has full control over the app and can use any SPA framework or library. However, this also means that the content author cannot edit the app using AEM’s content authoring experience, the SPA is not compatible with the template editor, and the developer cannot enable authoring in restricted areas of the app.References:

To create Sling Models that can export data in a human-readable yaml format, the following steps are required:

Create Sling models to export as yaml. Sling models are Java classes that can be used to represent resources in AEM. Sling models can use annotations to define how they can be adapted from a resource and how they can export data in different formats. To export data in yaml format, the Sling model class needs to use the @Model annotation with the resourceType parameter set to the resource type of the resource that the model represents. The Sling model class also needs to implement the org.apache.sling.models.annotations.Exporter annotation with the name parameter set to “jackson” and the extensions parameter set to “yaml”. The Sling model class also needs to use the @JsonProperty annotation on the fields or methods that need to be exported in yaml format.

Configure mime type in Apache Sling MIME Type Service. The Apache Sling MIME Type Service is an OSGi service that maps file extensions to MIME types and vice versa. To enable the yaml format for Sling models, the MIME Type Service needs to be configured with a new entry for the yaml extension and its corresponding MIME type, which is “application/x-yaml”. This can be done by creating an OSGi configuration for the org.apache.sling.commons.mime.internal.MimeTypeServiceImpl service and adding the entry “yaml=application/x-yaml” to the mime.types property.
