To obtain the EXIF tag from an image using node.js, you can use the exif
package which provides a simple interface to read EXIF data from images.
Here is an example code:
const exif = require('exif');
exif('path/to/image.jpg', (err, data) => {
if (err) {
console.log(err);
} else {
console.log(data);
}
});
In this code, we first require the exif
package. Then, we call the exif
function with the path to the image file as the first argument, and a callback function as the second argument. The callback function receives two arguments - err
and data
. If there was an error reading the EXIF data, err
will be set to the error object. Otherwise, data
will contain an object with the EXIF data.
You can then access individual EXIF tags by their name in the data
object. For example:
console.log(data.Make); // prints the make of the camera
console.log(data.DateTimeOriginal); // prints the date and time the photo was taken
Note that some EXIF tags may not be present in all images, so you should check whether the tag exists in the data object before attempting to access it.
