Component registry
Contents
Component registry#
The configuration registry has a component registry integrated on itself. These registry stores by a given name the components. Later you can retrieve them by this name, and use them in your code. The idea behind is to provide an alternative and more convenient way to customize components. You can override programmatically such registrations from your add-on or projects because it's stored in the configuration registry. You can customize a component without using shadowing at all, if the code that calls the component retrieves the information of the component to use from the component registry. You can even have modifiers to the component registrations: dependencies. So you can "adapt" the call given an array of such dependencies.
Registering components by name using config.registerComponent
#
Typically from an add-on or project configuration:
import MyToolbarComponent from './MyToolbarComponent'
config.registerComponent({
name: 'Toolbar',
component: MyToolbarComponent,
});
Retrieving a component from the component registry#
You can programmatically retrieve a component from the registry using config.getComponent
:
const Toolbar = config.getComponent('Toolbar').component
or by using the convenience component Component
if you want to use it in JSX directly
<Component componentName="Toolbar" {...props} />
Please notice that you are able to pass props
down to the retrieved component.
Adapting the component using dependencies
array#
You can register components, and retrieve them afterwards given a list of modifiers dependencies
.
import MyTeaserNewsItemComponent from './MyTeaserNewsItemComponent'
config.registerComponent({
name: 'Teaser',
component: MyTeaserNewsItemComponent,
dependencies: 'News Item',
});
and then retrieve it:
config.getComponent({
name: 'Teaser',
dependencies: ['News Item'],
}).component
The idea is that you can have both with and without dependencies:
import MyTeaserDefaultComponent from './MyTeaserDefaultComponent'
import MyTeaserNewsItemComponent from './MyTeaserNewsItemComponent'
config.registerComponent({
name: 'Teaser',
component: MyTeaserDefaultComponent,
});
config.registerComponent({
name: 'Teaser',
component: MyTeaserNewsItemComponent,
dependencies: 'News Item',
});
and then retrieve them both, depending on the use case (in the example, given a content type value coming from content
prop):
<Component componentName="Toolbar" dependencies={[props.content['@type']]} {...props} />
