Panel App Template

In this article, you’ll learn how to create a Liferay panel app and category as a Liferay module. To create a Liferay panel app and category via the command line using Blade CLI or Maven, use one of the commands with the following parameters:

blade create -t panel-app [-p packageName] [-c className] projectName

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.panel.app \
    -DartifactId=[projectName] \
    -Dpackage=[packageName] \
    -DclassName=[className] \
    -DliferayVersion=7.1

You can also insert the -b maven parameter in the Blade command to generate a Maven project using Blade CLI.

The template for this kind of project is panel-app. Suppose you want to create a panel app project called my-panel-app-project with a package name prefix of com.liferay.docs and a class name prefix of Sample. You could run the following command to accomplish this:

blade create -t panel-app -p com.liferay.docs -c Sample my-panel-app-project

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.panel.app \
    -DgroupId=com.liferay \
    -DartifactId=my-panel-app-project \
    -Dpackage=com.liferay.docs \
    -Dversion=1.0 \
    -DclassName=Sample \
    -Dauthor=Joe Bloggs \
    -DliferayVersion=7.1

After running the Blade command above, your project’s directory structure would look like this

  • my-panel-app-project
    • gradle
      • wrapper
        • gradle-wrapper.jar
        • gradle-wrapper.properties
    • src
      • main
        • java
          • com/liferay/docs/
            • application/list
              • SamplePanelApp.java
              • SamplePanelCategory.java
            • constants
              • SamplePanelCategoryKeys.java
              • SamplePortletKeys.java
            • portlet
              • SamplePortlet.java
        • resources
          • content
            • Language.properties
          • META-INF
            • resources
              • init.jsp
              • view.jsp
    • bnd.bnd
    • build.gradle
    • gradlew

The Maven-generated project includes a pom.xml file and does not include the Gradle-specific files, but otherwise, appears exactly the same.

The generated module is functional and is deployable to a Liferay Portal instance. The generated module, by default, creates a panel category with a panel app in Liferay Portal’s Product Menu. To build upon the generated app, modify the project by adding logic and additional files to the folders outlined above. You can visit the Customizing the Product Menu tutorial for instructions on customizing a panel app project.
