Exploring Widgets in AEM

A widget in AEM is a reusable piece of functionality that can be added to a component or template. Widgets can range from simple text fields to complex functionalities like calendars, sliders, or custom-built functionalities.

Setting Up an AEM Project

  1. Install AEM Developer Tools: If not already installed, add AEM Developer Tools to your Eclipse IDE.
  2. Create a New AEM Project: In Eclipse, go to “File” > “New” > “Other” > “Adobe Experience Manager” > “AEM Sample Multi-Module Project”. Follow the wizard to set up the project.

Creating a Custom Widget Script

  1. Navigate to the Component Folder: In your project, navigate to ui.apps/src/main/content/jcr_root/apps/<your-project>/components/content.
  2. Create a New .js File: This file will contain the code for your custom widget. The name should be descriptive of its function.
  3. Write the Widget Code: Write the JavaScript code for your widget. This will vary greatly depending on what your widget is designed to do.

Adding the Widget to a Component

  1. Create or Select a Component: In the content folder, create a new component or select an existing one to add the widget to.
  2. Edit the .html File: In the component’s .html file, add a script tag that references the .js file of your widget.

Testing the Custom Widget

After the widget has been added to a component, it’s essential to test it. This can be done by adding the component to a page in AEM and checking if the widget functions as expected.

Best Practices for Custom Widgets

  • Code Clarity: Ensure that your widget code is clean and well-commented. This will make it easier to maintain and troubleshoot.
  • User Experience: Always keep the end-user in mind. Widgets should enhance the user experience, not complicate it.
  • Testing: Always test a new widget thoroughly to ensure it’s functioning as expected.

Troubleshooting Common Issues

Creating custom widgets in AEM can sometimes present challenges. Here are a few common issues and their solutions:

Widget doesn’t appearCheck the script reference in the .html file to ensure it’s correct.
Widget doesn’t function correctlyReview your JavaScript code for any errors or bugs.
