id3-writer

ID3 Writer is a small and tested library for writing ID3 tags to MP3 files. We don't touch the files self - we speak to write adapters like libid3 or eyeD3. So this library is just a wrapper around the CLI programs.

I don't plan to support Windows explicit. But if someone requests a pull for a write adapter with Windows support I will not reject it.

Features

• Support for multiple write adapters
  • We check if some binaries are available to do the tasks
• Support for ID3v1 and ID3v2
  • ID3v2 Tags need some validation at this point
• Support for converting the encoding of the given tags
• Support for writing images to the MP3 files (eyeD3 only atm)

Getting Started

Installation

$ npm install id3-writer

API

Simply write ID3 tags

// Load and assign modules
var id3 = require('id3-writer');
var writer = new id3.Writer();

var file = new id3.File('/tmp/your.mp3');
var meta = new id3.Meta({
    artist: 'Blur',
    song: 'Song 2',
    album: 'Blur'
});

writer.setFile(file).write(meta, function(err) {

    if (err) {
        // Handle the error
    }

    // Done
});

Write ID3 tags with a additional image

// Load and assign modules
var id3 = require('id3-writer');
var writer = new id3.Writer();

var mp3 = new id3.File('/tmp/your.mp3');
var coverImage = new id3.Image('/tmp/cover.png');

var meta = new id3.Meta({
    artist: 'Blur',
    song: 'Song 2',
    album: 'Blur'
}, [coverImage]);

writer.setFile(file).write(meta, function(err) {

    if (err) {
        // Handle the error
    }

    // Done
});
