npm Vue.js Portlet Template

In this article, you’ll learn how to create an npm Vue.js portlet as a Liferay module. To create an npm Vue.js portlet via the command line using Blade CLI or Maven, use one of the commands with the following parameters:

blade create -t npm-vuejs-portlet [-p packageName] [-c className] projectName

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.npm.vuejs.portlet \
    -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 npm-vuejs-portlet. Suppose you want to create an npm Vue.js portlet project called my-npm-vuejs-portlet with a package name of com.liferay.npm.vuejs and a class name of MyNpmVuejsPortlet. Also, you’d like to create a service of type javax.portlet.Portlet that extends the com.liferay.portal.kernel.portlet.bridges.mvc.MVCPortlet class. Here, service means an OSGi service, not a Liferay API. Another way to say service type is to say component type. You could run the following command to accomplish this:

blade create -t npm-vuejs-portlet -p com.liferay.npm.vuejs -c MyNpmVuejsPortlet my-npm-vuejs-portlet

or

mvn archetype:generate \
    -DarchetypeGroupId=com.liferay \
    -DarchetypeArtifactId=com.liferay.project.templates.npm.vuejs.portlet \
    -DgroupId=com.liferay \
    -DartifactId=my-npm-vuejs-portlet \
    -Dpackage=com.liferay.npm.vuejs \
    -Dversion=1.0 \
    -DclassName=MyNpmVuejsPortlet \
    -DpackageJsonVersion=1.0.0 \
    -DliferayVersion=7.1

After running the Blade command above, your project’s directory structure looks like this:

  • my-npm-vuejs-portlet
    • gradle
      • wrapper
        • gradle-wrapper.jar
        • gradle-wrapper.properties
    • src
      • main
        • java
          • com/liferay/npm/vuejs
            • constants
              • MyNpmVuejsPortletKeys.java
              • MyNpmVuejsWebKeys.java
            • portlet
              • MyNpmVuejsPortlet.java
        • resources
          • content
            • Language.properties
          • META-INF
            • resources
              • js
                • index.js
              • init.jsp
              • view.jsp
    • .babelrc
    • .npmbundlerrc
    • bnd.bnd
    • build.gradle
    • gradlew
    • package.json

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 a working application and is deployable to a Liferay Portal instance. To build upon the generated portlet, modify the project by adding logic and additional files to the folders outlined above.
