Template prototype is like a master page template. Anything you configure in the prototype is applied to all page templates. The prototype makes configuration efficient as you only need to do it once. For example, add an area to the prototype to make it available on all pages. You can override the prototype at the page definition level if needed.
Put commonly used things in the template prototype. If most pages on your site have the same areas then define those areas in the prototype.
No, it is not necessary to use a prototype. You can configure a separate page definition for each page template instead. This works fine if you have a small number of templates that are very different from each other.
Prototype is an optional templating mechanism that offers a number of benefits:
Ensures uniformity across templates
Avoids repeating and duplicating configuration
Creates similar templates quickly
You can configure a prototype in:
If you have the Multisite module (DX Core) you can configure a different prototype for each site or use the same prototype for all sites.
In the site definition configure the prototype in the
Example: Prototype in the site definition in the Site app.
While it is not possible to configure a site definition completely in YAML, you can configure the prototype in YAML and reference it in the site definition. The prototype definition can reside in any module.
To configure the prototype in YAML:
In the site definition in
info.magnolia.module.site.templates.ReferencingPrototypeTemplateSettings. This class allows you to use a prototype defined in YAML.
prototypeIdto the location of the YAML prototype definition in the
<module name>:<relative path to definition>format, for example,
/prototypenode, if it exists.
travelsite definition in the Site app.
Create the prototype YAML file in the location defined in the
prototypeIdproperty and set the class property to
info.magnolia.module.site.templates.PrototypeTemplateDefinition(or a subclass).
Prototype is a TemplateDefinition which means it supports the same properties as page definition, including common template properties. However, typically you don’t use them all. Here are the typical use cases:
A page template script typically starts with an opening
Example: The travel demo demo
defines a template script in the prototype. This common script is used
for all pages. It is also the reason why no YAML page definition in the
demo has an explicit
A custom definition class which extends ConfiguredTemplateDefinition, an implementation of TemplateDefinition. You only need a custom class if you want to add your own nodes and properties in the prototype. Implement corresponding methods to operate on those properties in the definition class.
When a user requests a page Magnolia merges the prototype with a page definition. The result is a merged template definition which is then used to render the page.
The merged definition is virtual. You won’t find its configuration
anywhere. It is created dynamically at the time of rendering. However,
you can access the merged definition in a template script using the
Example: Merging a prototype (configured in JCR) with a home page definition (configured in YAML)
Prototype defines the
mainarea type as
list. Page definition adds
availableComponentsfor the area. The result contains both.
Prototype defines a
templateScript. Page definition says nothing about script. The result is that the home page uses the script defined in the prototype.
Prototype defines the
footerarea as not editable. Page definition overrides this decision by allowing footer editing on the home page. The result is that the footer can be edited on the home page only.
