laravel, statamic

I use Cloudflare to cache pages for a day. Recently I built the Arbeitnow blog using Statamic. When I update the content, I want the cache to be updated and the latest changes to be shown to the visitor.

When I deploy changes to content, I added a new Laravel command as part of the deployment flow. Important thing to note is that the Purge by single-file (by URL) allows only 30 entries at a time.

With statamic, I just grab the URLs from the Entry repository for a single collection. You could filter more, perhaps grab only records that have been updated in the last day, or since the last deployment.

This is what I have in the handle method. For this, you need two things:

  • Zone ID (it’s on your site page in Cloudflare portal)
  • API Key (Generate one here with permissions for clearing / purging cache in a zone)
permissions for clearing / purging cache
// use config() to grab it from your environment
$apiKey = ''; 
$zoneId = '';

$all = Entry::query()
            ->where('collection', 'collection_name')
            ->where('published', true)
            ->get();

        foreach ($all->chunk(30) as $entries){
            $files = [];
            /** @var Entry $entry */
            foreach ($entries as $entry){
                $files[] = url($entry->uri);
            }

            $urls = [
                'files' => $files
            ];

            $http = Http::withBody(json_encode($urls),'application/json')
                ->withToken($apiKey)
                ->post('https://api.cloudflare.com/client/v4/zones/' . $zoneId . '/purge_cache');

            $this->info('Submitted to Cloudflare with status: ' . $http->status());

            if (!$http->ok()){
                dump($http->body());
            }

        }
