You can use the cache
class to cache the data you parsed from the blueprint (this code belongs in a controller):
$data = cache::get('cachekey');
if(!$data) {
// get data somehow
$data = somefunction();
// cache it
cache::set('cachekey', $data);
}
return compact('data');
Please note that you need to enable the cache so that Kirby can store the data in the site/cache
directory. You could however use c::set('cache.ignore', ['*']);
to disable the page cache.
