Static resources

We often want to ship a website with a static resource, such as an image, icon, CSS, or JavaScript file. For this, we need to register static resources.

Registering JavaScript and CSS

To register a static resource in Plone 6, we need to use the plone.base.interfaces.resources.IBundleRegistry interface.

The following example registers a JavaScript resource in browser/profiles/default/registry of your Plone 6 project. The JavaScript files have to be in the browser/static folder of your Plone 6 project.

<registry>
  <records interface="plone.base.interfaces.resources.IBundleRegistry" prefix="plone.bundles/jscript">
    <value key="enabled">True</value>
    <value key="jscompilation">++plone++myproject.site/javascript.min.js</value>
    <value key="load_async">False</value> 
    <value key="load_defer">False</value>
    <value key="depends">plone</value>
  </records>
</registry>

You can register a CSS resource in the same way.

    <registry>
    <records interface="plone.base.interfaces.resources.IBundleRegistry" prefix="plone.bundles/css">
      <value key="enabled">True</value>
      <value key="csscompilation">++plone++myproject.site/style.min.css</value>
      <value key="depends">plone</value>
    </records>
  </registry>

Registering a JavaScript file and a CSS file in the same bundle is also possible.

<registry>
  <records interface="plone.base.interfaces.resources.IBundleRegistry" prefix="plone.bundles/css">
    <value key="enabled">True</value>
    <value key="csscompilation">++plone++myproject.site/style.min.css</value>
    <value key="jscompilation">++plone++myproject.site/javascript.min.js</value>
    <value key="load_async">False</value> 
    <value key="load_defer">False</value>
    <value key="depends">plone</value>
  </records>
</registry>

Available attributes

The following attributes are available for registering a static resource:

enabled

Whether the bundle is enabled or not. If it is disabled, the bundle will not be loaded.

jscompilation

The path to the compiled JavaScript file.

csscompilation

The path to the compiled CSS file.

depends

A list of bundles that this bundle depends on.

load_async

Whether the bundle should be loaded asynchronously or not. Only JavaScript

load_defer

Loading order of resources

depends is used to define the loading order of resources, by specifying the name of the depending bundle.
