Statamic Cloudflare Purge

This addon will hook into your already existing statamic invalidation and purge any pages that have been invalidated from your Cloudflare cache.

Installation

composer require justbetter/statamic-cloudflare-purge

Usage

You need a Cloudflare API key with the Zone.Cache Purge permission, and set it in your .env:

CLOUDFLARE_API_TOKEN="token_here"

You will also have to define the zone of your website:

CLOUDFLARE_ZONE="zone_id_here"

Finally, enable the package:

CLOUDFLARE_PURGING_ENABLED=true

If you have a multistore setup with multiple zones, see the Configuration section.

This package listens to the UrlInvalidated event and adds every invalidated URL to a temp file. It also listens to certain events as defined in the config file to flush the whole cache.

Then, when you run the statamic:cloudflare:purge command or the PurgeCloudflareCachesJob job, these files will get purged from the Cloudflare cache. As such, you should add this to your routes/console.php like so:

Schedule::job(\JustBetter\StatamicCloudflarePurge\Jobs\PurgeCloudflareCachesJob::class)->everyFiveSeconds()->withoutOverlapping();

Be aware of the rate limits on the API. You're probably not going to run into any issues, but it's possible. Especially if you end up calling an everything-purge often and you're on a free plan, or have a lot of sites running on the same Cloudflare account.

Configuration

You can publish the config with the following command:

php artisan vendor:publish --provider="JustBetter\StatamicCloudflarePurge\StatamicCloudflarePurgeServiceProvider"

Multiple zones

Using the configuration file you can define multiple zones. There are 3 ways of defining the zone in your config:

// Single zone
'zone' => 'zone_id',

// Multiple zones based on statamic site handles
'zone' => [
    'default' => 'zone_id_default',
    'french' => 'zone_id_french',
    ...
],

// Complete freedom with a callback
'zone' => function() {
    return \App\Facades\Custom::getCloudflareZone()
},

Cache flushing

You can define any events that will trigger a full cache purge immediately in the config file. By default, these three events have been defined for this purpose:

'flush-events' => [
    \Statamic\Events\GlobalSetSaved::class,
    \Statamic\Events\NavSaved::class,
    \Statamic\Events\StaticCacheCleared::class,
],
