Upload worker to CloudFlare

Environment Variables

The following environment variables are supported and match Wrangler behavior:

CLOUDFLARE_ACCOUNT_ID

The account ID for the Workers related account.

CLOUDFLARE_API_TOKEN

The API token for your Cloudflare account, can be used for authentication for situations like CI/CD, and other automation.

CLOUDFLARE_API_KEY

The API key for your Cloudflare account, usually used for older authentication method with CLOUDFLARE_EMAIL=.

CLOUDFLARE_EMAIL

The email address associated with your Cloudflare account, usually used for older authentication method with CLOUDFLARE_API_KEY=.

Note that either CLOUDFLARE_API_TOKEN or CLOUDFLARE_EMAIL/CLOUDFLARE_API_KEY environment variable pair are required

Steps we take:

Get account id. CLOUDFLARE_ACCOUNT_ID environment variable will be checked first. If not, GET https://api.cloudflare.com/client/v4/accounts/
Check if the worker exists: GET https://api.cloudflare.com/client/v4/accounts//workers/services/<worker_name> 404 - does not exist
Add the "script" PUT https://api.cloudflare.com/client/v4/accounts//workers/scripts/<worker_name>?include_subdomain_availability=true&excludeScript=true
Get the "subdomain". I believe this is simply to determine the test url: GET https://api.cloudflare.com/client/v4/accounts//workers/subdomain
Enable the script: This is only done if the script did not exist. Subsequent flows leave this alone POST https://api.cloudflare.com/client/v4/accounts//workers/scripts/<worker_name>/subdomain Data: { "enabled": true }
