Purges your Heroku application's Cloudflare cache on deployment.

This buildpack makes use of Heroku's built-in multi buildpack functionality to make a HTTP DELETE request to the Cloudflare purge all files API. Each time you deploy your Heroku app, the cache will be cleared.

Configuration

You will need:

1. Your Cloudflare API key and email address
2. The Zone ID of the site that Cloudflare is caching

Run the following against your Heroku application:

heroku config:set CF_EMAIL=email@example.com
heroku config:set CF_ZONE_ID=my_zone_id
heroku config:set CF_AUTH_KEY=my_cloudflare_api_key

heroku buildpacks:add https://github.com/jamesmartin/cloudflare-cache-purge-buildpack.git
git push heroku master

Getting your Zone ID

The Cloudflare Zone ID for your site can be obtained via the API:

1. Clone this repository locally
2. Edit the cf file to include your Cloudflare API key and email address
3. Run the zones command:

  $ ./cf bin/zones

1. Find the Zone ID of your site in the JSON output of zones. E.g:

{
  "result": [
  {
    "id":"this-is-your-zone-id",
    "name":"example.com",
    "status":"active",
    ...
