how to pass environment variable to shopify config on cloudflare workers?

[yangcheng]

I am setting up my delegate access token and need to save is as a secret.

On Cloudflare workers, environment variables are passed to handler, which is defined in the worker.js for a hydrogen app
now how should I let hydrogen.config.js to read from values passed in to worker.js's handler?

export default {
  fetch(request, env, context) {
    //env.PRIVATE_STOREFRONT_TOKEN is available here 
    return new Response('Hello');
  },
};

how do I reference env in hydrogen.config.js

Thanks

what I did now is create a singleton like object and reference the object in both place. I wonder there is more preferred way for shopify config to get information about the request/handler

When deploying to a platform different from Oxygen, you need to polyfill the global Oxygen.env with something like this. Then, it should be possible to reference Oxygen.env.MY_VARIABLE from hydrogen.config.js without issues.
