sift: Static files not working when deployed

Thanks for the patience, @wezm! I fixed the issue and released a new version 0.3.4. Please try it out and let me know if you face any issues.

The image does not load locally or when deployed.

There’s a tracking issue (https://github.com/denoland/deployctl/issues/60) on deployctl. But you’ll soon be able to run sift using deno without the need for deployctl, which should fix the local static assets issue.

@satyarohith The browser will reject a mutated headers object

// in line 76 you are trying to mutate the existing header
for (const [key, value] of newHeaders) {
   existingHeaders.set(key, value);
}

Instead, build a fresh set of headers from the existing and the browser will accept them.

// replace with the following 
// first place the existingHeaders in a new headers object
const newHeaders = new Headers(existingHeaders);
// do any housekeeping with this set...
 if (newHeaders.has("x-github-request-id")) {
    newHeaders.delete("content-security-policy");
  }
// then add you contentType header...
  for (const [key, value] of headers) {
    newHeaders.set(key, value);
  }
// finally, return the newHeaders object in a new Responce object
// line 80
  return new Response(res.body, {
    headers: newHeaders,
    status: res.status,
    statusText: res.statusText,
  });

I learned this the hard way when I built my own static file server for Deploy … https://clock.deno.dev/ SEE: https://github.com/nhrones/DotClock
