Different file size limitation based on file type

I have an endpoint to upload files. I would like to have different file size limits depending on the file type. Images size limit =< .5 MB and PDF size limit =< 2MB.

The limits.fileSize options only allows for one value, and I can’t do it in the fileFilter property either… So how could I do it?

I think you should be able to do it with the fileFilter property?

function fileFilter (req, file, cb) {
  if (file.mimetype === 'application/pdf' && file. size > 2 * 1014 * 1024) {
    return cb(new Error('File too large'))
  }

  cb(null, true)
}

Hi @LinusU

I have the same problem on Multer 1.4.2. I need to limit the file size on base of the file type for my project. It would be really nice, if that would be possible inside the file filter function.

Or can you expect when there will be a stable release for Multer 2.0?
