cyzyvos Comments - Answer Overflow

thanks @cyb3rjak3! that's what I was afraid of. Unfortunately, I'm trying to get this to work in Deno so wrangler is not an option. just for reference – this is where the magic happens in wrangler, I think: https://github.com/cloudflare/workers-sdk/blob/main/packages/wrangler/src/pages/upload.tsx

Is it possible to upload a worker script (w/ ESM syntax) using the API?

Unfortunately, I don't think that's the case. If I try to deploy my script via the API, I get the following error response:

{
  result: null,
  success: false,
  errors: [
    {
      code: 10021,
      message: "Uncaught SyntaxError: Unexpected token 'export'\n  at worker.js:432\n"
    }
  ],
  messages: []
}

{
  result: null,
  success: false,
  errors: [
    {
      code: 10021,
      message: "Uncaught SyntaxError: Unexpected token 'export'\n  at worker.js:432\n"
    }
  ],
  messages: []
}

If I paste the exact same code into the dashboard editor, it works. Also, the API doc explicitly states that only the service worker syntax is supported: https://developers.cloudflare.com/api/operations/worker-script-upload-worker-module#request-body
