Using the hook to dynamically register extensions from plugins

This hook is triggered when Kirby and all plugins have been loaded, so you can safely access any Kirby objects from this hook.

This can be used to dynamically register additional extensions based on a config option, site content or even the availability of other plugins:

<?php

Kirby::plugin('superwoman/superplugin', [
    'hooks' => [
        'system.loadPlugins:after' => function () {
            // access any Kirby object using kirby(), site() or page()
            $uri = site()->content()->blogPage();

            // register additional extensions like you would
            // directly in the Kirby::plugin() call
            kirby()->extend([
                'routes' => [
                    [
                        'pattern' => $uri,
                        'action'  => function () {
                            // ...
                        }
                    ]
                ]
            ], kirby()->plugin('superwoman/superplugin'));
        }
    ]
]);
