Try the function like below,

function(req,res){
  gfs.files.findOne({ filename: req.params.filename }, (err, file) => {
    res.contentType(file.contentType);
    // Check if image
    if (file) {
      // Read output to browser
      const readstream = gfs.createReadStream(file.filename);
      readstream.pipe(res);
    } else {
        console.log(err);
    }
  });
};
