Is it possible to manually set the content-type header in reply.file()?

I have a file that I would like to serve from my local filesystem. That file, however, is not named according to naming conventions. Instead, I have stored some metadata elsewhere (in my database) about that particular file. What I'd like to do is say something like

reply.file(req.pre.item.actual_filename,
  {
    filename: req.pre.item.user_filename,
    mode: 'inline',
    'content-type': req.pre.item.mime_type
  });

It seems like hapijs just keeps saying 'octet stream' no matter how hard I try to convince it. I could store all my files in the local system with extensions, but that's not really what I want to do. I'd rather have hapi reply with the proper filetype.

reply(content).header('Content-Type', contentType).header("Content-Disposition", "attachment; filename=" + file);

contentType can be one of following:

case "pdf":
    contentType = 'application/pdf';
    break;
case "ppt":
    contentType = 'application/vnd.ms-powerpoint';
    break;
case "pptx":
    contentType = 'application/vnd.openxmlformats-officedocument.preplyentationml.preplyentation';
    break;
case "xls":
    contentType = 'application/vnd.ms-excel';
    break;
case "xlsx":
    contentType = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet';
    break;
case "doc":
    contentType = 'application/msword';
    break;
case "docx":
    contentType = 'application/vnd.openxmlformats-officedocument.wordprocessingml.document';
    break;
case "csv":
    contentType = 'application/octet-stream';
    break;

I think this is a bug in hapi. The following should work:

reply.file(req.pre.item.actual_filename,
{
  filename: req.pre.item.user_filename,
  mode: 'inline'
}).type(req.pre.item.mime_type);

I submitted a pull request to fix this issue (#1956). Will update this answer when the pull request gets accepted and released.

EDIT: The change was accepted, it will be in the 6.9.0 release.

EDIT 2: Hapi 6.9.0 has been released with this change in it.

Seems like the easiest thing to do is not use reply.file and instead just open the stream on my own and reply with it, thusly:

serveItem: (req, reply)->
  out = fs.createReadStream path.resolve(tmpFolder, req.pre.item.get('real_filename'))
  reply(out).type(req.pre.item.get('mime_type'))
