  • opts.fileName {String} - File name with extension, like name.ext
  • opts.type {String} - Mime-type, like image/png
  • opts.size {Number} - File size in bytes, if not set file size will be calculated from Buffer
  • opts.meta {Object} - Object with custom meta-data
• callback {Function} - Triggered after file is written to FS. With error, and fileRef, where fileRef is a new record from DB
• Returns {Files} - Current FilesCollection instance

var Images = new FilesCollection({collectionName: 'Images'});

fs.readFile('/data/imgs/sample.png', function (error, data) {
  if (error) {
    throw error;
  } else {
    Images.write(data, {
      fileName: 'sample.png',
      type: 'image/png'
    }, function (error, fileRef) {
      if (error) {
        throw error;
      } else {
        console.log(fileRef.name + ' is successfully saved to FS. _id: ' + fileRef._id);
      }
    });
  }
