Once you’ve exposed your modules
package.json file, you can use them in your portlets. The
require attribute makes it easy.
This tutorial covers how to access in your portlets the modules you’ve exposed.
The example module
logger.es was written inside the
Console Logger Portlet.
Once the portlet is deployed, and added to a page, you’ll notice a printout in
Follow the steps below to use your exposed modules in your portlets.
auitaglib in a JSP in your view:
<%@ taglib uri="http://liferay.com/tld/aui" prefix="aui" %>
Note: if you created the portlet using Blade, the
auitaglib is already provided for you in the
aui:scripttag to the JSP and set the
requireattribute to the relative path for your module.
Since Liferay DXP 7.0, the
requireattribute allows you to include your exposed modules in your JSP. The AMD Loader fetches the specified module and its dependencies. For example, the Console Logger Portlet’s
view.jspincludes the module
<aui:script require="js-logger/logger.es"> var Logger = jsLoggerLoggerEs.default; var loggerOne = new Logger('*** -> '); loggerOne.log('Hello'); var loggerDefault = new Logger(); loggerDefault.log('World'); </aui:script>
References to the module within the script tag are named after the
requirevalue, in camel-case and with all invalid characters removed. The
jsLoggerLoggerEsis derived from the module’s relative path value
js-logger/logger.es. The value is stripped of its dash and slash characters and converted to camel case.
Thanks to the
aui:script tag and its
require attribute, using your modules
in your portlet is a piece of cake!
