Cache binary

Hi,

I’d like to use Cloudflare Workers as a CDN like explained on this tutorial: https://developers.cloudflare.com/workers/tutorials/configure-your-cdn (full code at the end)

it works well without Worktop but I did not find out how to make it work with worktop as I just received the JSON body property instead of the binary:

{
    "locked": false
}

I wonder what would be the equivalent of response = new Response(response.body, { ...response, headers }) with worktop. Here is the actual code:

API.add("GET", "/assets/:id", async (req, res) => {
  const response = await fetch("https://f001.backblazeb2.com/file/asset/file.jpg");
  res.send(200, response.body);
});

Cache.listen(API.run);

Any idea ?

Yes that method auto-casts the input to standard/common formats. That’s why end() is available and why you can also directly return Responses from handlers

If I use res.send(200, response.body, {...}, I then get that response:

{
    "locked": false
}

I dont think you can get the raw bytes without calling blob() first. Also it seems that send function (in response) can’t handle binary content:

if (data == null) {
	data = '';
} else if (dtype === 'object') {
	data = JSON.stringify(data);
	type = type || 'application/json;charset=utf-8';
} else if (dtype !== 'string') {
	data = String(data);
}

This is why I used end function directly
