An Ext plugin is a powerful tool for extending Liferay DXP. Because it increases
the complexity of your Liferay DXP installation, you should only use an Ext plugin
if you’re sure you can’t accomplish your goal in a different way. You can
create Ext plugins using the pre-configured war-core-ext project
template/archetype. See the
war-core-ext
project template article for information on how to create an Ext plugin, its
folder structure, and other important details.
It’s recommended to create and develop your Ext plugin in a
Liferay Workspace.
Workspace is preconfigured with an ext folder, which applies important
settings (via the LiferayExtPlugin) to your Ext plugin when it’s deployed to
Liferay DXP. You’ll learn more about this in the
Set Up the Build Environment
section.
Next you’ll learn the anatomy of an Ext plugin.
