Statamic SWR Static Cache
Allows you to add stale while revalidate functionality to the application static cache driver.
Requirements
This add-on currently requires you to use Redis as a cache driver.
Additionally, you'll need to process queue items with a separate worker - if you're using the sync driver, this add-on won't have any effect.
Installation
From a standard Statamic V3 site, you can run:
composer require daynnnnn/statamic-swr-cache
Then you'll just need to add the stale while revalidate strategy to your static cache config:
'strategies' => [
...
'swr' => [
'driver' => 'swr',
'expiry' => '60',
'stale' => '5',
],
],
How it works
In the above example, cached pages will stay in the cache for 60 minutes (expiry), but if the cached page is accessed when the cache is over 5 minutes old (stale), a background job will run to update the cache, but the currently cached page will still be served.
Other than this, the cache will stay the same as the application cache.
