read-exif

A Node.js module to get Exif data from a JPEG file

const readExif = require('read-exif');

(async () => {
  const exif = (await readExif('example.jpg')).Exif;

  // 34855: ID of the `ISOSpeedRatings` tag
  exif['33434']; //=> 250

  // 36868: ID of the `DateTimeDigitized` tag
  exif['36867']; //=> '2018:06:03 08:49:11'
})();

Designed to be memory and CPU efficient, as this module doesn't read entire file contents but read only a necessary part of a file.

Use npm.

npm install read-exif
