This is a cloudflare worker configuration for use in front of a GameVault server. It watches the ~/api/games/* API endpoint, and redirects downloads to content served from Backblaze B2. As the content is served through cloudflare, you are not charged an egress fee on any of the bandwidth.

Requirements

• A free Cloudflare account
• An owned domain with DNS records pointing to your gamevault server on Cloudflare
• A GameVault server set up and configured
  • GameVault server exposed to the open internet (cloudflare tunnels work just fine)
• A Backblaze B2 account
• Game files mirrored onto the B2 account.
  • Optionally, you can use rclone to mount the B2 bucket on the GameVault server, to cut down on the work.

Steps to use

1. Create a new cloudflare worker here
2. Edit the worker settings as follows:
   1. Set the route (in Settings>Triggers) of the worker to [gamevault base domain]/api/games/*.
      • You likely want to disable the default route.
   2. Create the following variables (in Settings>Variables):

      Variable name	Value	Example	Required?
      B2_APPLICATION_KEY	Your B2 application key, encrypted.	00123b4567df3c60000000007	Required
      B2_APPLICATION_KEY_ID	Your B2 application key ID.	K001mcp0RsiEJe/Viw90bvjkZZPzRSE	Required
