Potential Issues

This plugin does not support features reserved for Enterprise Cloudflare Workers.


PR's are very much welcome. Here are some fun ideas to consider:

  • [ ] Write hella' cool automated tests
  • [ ] Support other neat Cloudflare Worker features like Workers KV and wasm

Feel free to create an issue throwing your own ideas at me.
