Hi Arjun,

You can embed all js and css files in theme so that you can make use of same across whole portal, you can load js files in portal_normal.vm and css files inside main.css in theme.

At a later stage of the project, you can also perform javascript minification for performance improvement.

Thanks.

Hello Arjun,

It is possible to specify multiple header-portlet-javascript elements in liferay-portlet.xml

<header-portlet-javascript>/js/main.js</header-portlet-javascript>
<header-portlet-javascript>/js/main2.js</header-portlet-javascript>
<header-portlet-javascript>/js/main3.js</header-portlet-javascript>

The script tags will get rendered accordingly within the head tags :-)

HTH!
Suraj

Hi,

Its possible to add multiple javascript files in <header-portlet-javascript>. But you need to maintain the order in which they shall be rendered ,so need to be careful that there are no conflicts. So if there is requirement of having multiple instances (that is, something like web content portlet that can be placed several times in a page) of same portlet on a single page / or having portlet specific javascript you can add in liferay-portlet.xml.
When the page is being rendered, all of the entries are checked, liferay will only load the js file once. Thus, the page is going to load faster.

But if you have javascript files, affecting entire portal, then its advised to put them in Theme and included in portal_normal.vm.

HTH!

For reference checkout the documentation

https://www.liferay.com/documentation/liferay-portal/6.1/development/-/ai/creating-liferay-them-7

In 'Anatomy of a Theme' you will find portal_normal.vm

HTH!
