ghost-cache-purge

A Cloudflare Worker to purge cached pages when a post is published or updated on Ghost.

❓ Why

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. When a post is published or updated a webhook will trigger this worker to purge that page from the cache.

📙 Usage

🚀 Deploy Worker

Go to your Cloudflare account and create an API token with the Zone.Cache Purge permission.

Set the CF_ZONE_ID secret:

wrangler secret put CF_ZONE_ID

Set the CF_API_TOKEN secret:

wrangler secret put CF_API_TOKEN

Set a SECRET_TOKEN for the webhook URL:

wrangler secret put SECRET_TOKEN

Set the GHOST_URL environment variable at wrangler.toml:

[vars]
GHOST_URL = "https://YOUR-BLOG-DOMAIN/"

Publish to Cloudflare:

wrangler publish

🪝 Set up Ghost integration

Go to Ghost admin Settings-->Integrations and create a new custom integration named Cloudflare Cache Purge.

Now add webhooks for events:

NAME	EVENT	URL	LAST TRIGGERED
Ping Worker	Post published	https://YOUR-WORKER-SUBDOMAIN.workers.dev/SECRET_TOKEN/postPublished	Not triggered
Ping Worker	Published post updated	https://YOUR-WORKER-SUBDOMAIN.workers.dev/SECRET_TOKEN/postUpdated	Not triggered
