Worker works, now for storage: https://developers.cloudflare.com/workers/reference/storage/overview

• Buy the unlimited plan ($5 USD and also bumps worker limits)
• Go to the dashboard, Workers and KV
• Create a new namespace, test
• Extend wrangler.toml:

kv-namespaces = [
  { binding = "kv", id = "" }
]

Now the namespace is available under the variable name kv in the code.

GitHub Actions:

Add the token from https://dash.cloudflare.com/profile/api-tokens to a secret named CF_API_TOKEN.

Then use this workflow file:

name: worker
on:
  push:
    branches:
    # Limit to the `master` branch
    - master
jobs:
  worker:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v1
    - name: Run Wrangler
      env:
        CF_API_TOKEN: ${{secrets.CF_API_TOKEN}}
      run: |
        npx @cloudflare/wrangler publish

That's it! Any changes to the repo will now replace the worker.

Secret Storage

There is supposed to be a Secrets Vault service in the future, but for now KV is the way to go. The worker code is also a possibility, it is not reachable from the outside of Cloudflare.
