A simple Cloudflare Worker to purge cached pages when a post is published or updated from the Ghost CMS administration pages.
With this worker you can run your Ghost blog with a Cache Everything Page Rule on Cloudflare and serve all content (including HTML pages) from Cloudflare's cache. This allow you to reduce the resources used on your server and deliver pages more quickly with more scalability.
When a post is published or updated a Ghost webhook will trigger this worker to purge that page from the Cloudflare cache.
This project is a fork of 'milgradesec/ghost-cache-purge-worker'.
This fork supports multiple Ghost sites in different Cloudflare Zones ID. Usefull if you manage multiple Ghost projects !
The only settings to push is the API token to allow this Worker to clean the content cache.
Go to your Cloudflare account and create an API token with the Zone.Cache Purge permission.
Install the Wrangler command line :
npm install -g wranglerLogin for the first time with your Cloudflare account :
wrangler loginSet the CF_API_TOKEN secret with the API token previously created :
wrangler secret put CF_API_TOKENThe secret is the API Token created.
Publish the script to Cloudflare:
wrangler deployGo to Ghost admin Settings-->Integrations and create a new custom integration named Cloudflare Cache Purge.
Now add 2 webhooks in the bottom on the custom integration page :
| NAME | EVENT | URL |
|---|---|---|
| Ping Worker | Post published | https://YOUR-WORKER-SUBDOMAIN.workers.dev/CLOUDFLARE_ZONE_ID/postPublished |
| Ping Worker | Published post updated | https://YOUR-WORKER-SUBDOMAIN.workers.dev/CLOUDFLARE_ZONE_ID/postUpdated |
When you publish a new post : The sitemap, RSS feed and the homepage are purged. When you update a post : The sitemap, RSS feed and the post are purged.
By default Ghost doesn't send any caching header for the frontend pages and the content API. You can overide this default behaviour by adding a JSON configuration block in the configuration file of Ghost :
"caching": {
"contentAPI": {
"maxAge": 86400
},
"frontend": {
"maxAge": 86400
}
}Start by updating an existing post with a new content. Check that the content appears on the Webpage. If you have any issue, you can enable the log with "Begin log Stream" button in the "log" tab.
