Usage

id3.read(path, [opts])

The read method returns a promise for a ReadResult or an array of ReadResult of the path requested. The path parameter is a String with the path (relative or absolute) of a file or folder. The optional opts parameter is an object with the following properties:

• recursive: Read recursively when the path parameter is a folder path. ( Boolean. Default: true )
• each: A function to be called for each result ( Function (ReadResult). Default: null )

For example:

var id3 = require('music-tag');

id3.read('music.mp3').then(function(result) {
	console.log(result.data);
}).fail(function(err) {
	throw err;
});

id3.write(path, tags, [opts])

The write method returns a promise for a WriteResult or an array of WriteResult of the path requested. The path parameter is a String with the path (relative or absolute) of a file or folder. The tags parameter is an object with the new tags to add to the path. The optional opts parameter is an object with the following properties:

• recursive: Write recursively when the path parameter is a folder path. ( Boolean. Default: true )
• each: A function to be called for each result ( Function (WriteResult). Default: null )
• replace: Removes any previously existing tag. ( Boolean. Default: false )

For example:

var id3 = require('music-tag');

id3.write('music.mp3', { artist: 'Me' }).then(function(result) {
	console.log(result.tags);
}).fail(function(err) {
	throw err;
});
