metalsmith-media-metadata

Adds metadata to image and video metalsmith file objects. Only really useful when used in conjunction with other plugins.

Example

The output of exiftool is added as metadata into the metalsmith file object for any media file:

{
  'dog.jpg': {
    // Existing file data untouched
    exif: {
      Sharpness: 'Normal',
      SubjectDistanceRange: 'Unknown',
      GPSLatitudeRef: 'North',
      GPSLongitudeRef: 'East',
      GPSAltitudeRef: 'Above Sea Level',
      GPSTimeStamp: '14:27:07.24',
      GPSSatellites: '06',
      GPSImgDirectionRef: 'Unknown ()',
      GPSMapDatum: 'WGS-84   ',
      GPSDateStamp: '2008:10:23',
      Compression: 'JPEG (old-style)',
      ThumbnailOffset: 4560,
      ThumbnailLength: 6702,
      ImageWidth: 640,
      ImageHeight: 480,
      EncodingProcess: 'Baseline DCT, Huffman coding',
      BitsPerSample: 8,
      ColorComponents: 3,
      // Many, many fields...
    }
  }
}

Usage

const mediaMetadata = require('metalsmith-media-metadata');
 
metalsmith.use(mediaMetadata({
  // Only process jpegs
  path: '**/*.+(jpg|jpeg)'
}));

There are two configuration options:

• cache: Save exif data alongside images (default: false)
• path: minimatch case-insensitive glob that determines which files get processed (default: **/*.+(gif|jpg|mp4|png))

Requirements

• exiftool: Depending on your platform, installing dist-exiftool may be the easiest way to go.
