node-id3

node-id3

node-id3 is an ID3-Tag library written in JavaScript.

Installation

npm install node-id3

Usage

const NodeID3 = require('node-id3')

/* Variables found in the following usage examples */

const filebuffer = Buffer.from("Some Buffer of a (mp3) file")
const filepath = './path/to/(mp3)file'

const tags = {
    title: "Tomorrow",
    artist: "Kevin Penkin",
    album: "TVアニメ「メイドインアビス」オリジナルサウンドトラック",
    APIC: "./example/mia_cover.jpg",
    TRCK: "27"
}

Write tags to file

If you have an existing file/buffer (e.g. an mp3 file) you can use the write method to write your tags into it. It will remove existing tags and add yours.

const success = NodeID3.write(tags, filepath) // Returns true/Error
// async version
NodeID3.write(tags, file, function(err) {  })

Write tags to filebuffer

const success = NodeID3.write(tags, filebuffer) // Returns Buffer
// async version
NodeID3.write(tags, file, function(err, buffer) {  })

Update existing tags of file or buffer

The update method works like the write method but will keep or overwrite existing tags instead of removing them.

const success = NodeID3.update(tags, filepath) //  Returns true/Error
const success = NodeID3.update(tags, filebuffer) //  Returns Buffer
NodeID3.update(tags, filepath, function(err, buffer) {  })
NodeID3.update(tags, filebuffer, function(err, buffer) {  })

// Possible options
const options = {
    include: ['TALB', 'TIT2'],    // only read the specified tags (default: all)
    exclude: ['APIC']            // don't read the specified tags (default: [])
}

NodeID3.update(tags, filepath, options)
const success = NodeID3.update(tags, filebuffer, options)
NodeID3.update(tags, filepath, options, function(err, buffer) {  })
NodeID3.update(tags, filebuffer, options, function(err, buffer) {  })

Create tags as buffer

The create method will return a buffer of your ID3-Tag. You can use it to e.g. write it into a file yourself instead of using the write method.

const success = NodeID3.create(tags) // Returns ID3-Tag Buffer
// async version
NodeID3.create(tags, function(buffer) {  })

Reading ID3-Tags

const tags = NodeID3.read(file)
NodeID3.read(file, function(err, tags) {})
/*
    tags: {
        title: "Tomorrow",
        artist: "Kevin Penkin",
        image: {
          mime: "image/jpeg",
          type: {
            id: 3,
            name: "front cover"
          },
          description: String,
          imageBuffer: Buffer
        },
        raw: {
          TIT2: "Tomorrow",
          TPE1: "Kevin Penkin",
          APIC: Object (See above)
        }
      }
*/

// Possible options
const options = {
    include: ['TALB', 'TIT2'],    // only read the specified tags (default: all)
    exclude: ['APIC'],            // don't read the specified tags (default: [])
    onlyRaw: false,               // only return raw object (default: false)
    noRaw: false                  // don't generate raw object (default: false)
}
const tags = NodeID3.read(file, options)

Removing ID3-Tags from file/buffer

const success = NodeID3.removeTags(filepath)  //  returns true/Error
NodeID3.removeTags(filepath, function(err) {  })

let bufferWithoutID3Frame = NodeID3.removeTagsFromBuffer(filebuffer)  //  Returns Buffer

Using Promises (available starting with v0.2)

const NodeID3Promise = require('node-id3').Promise

NodeID3.write(tags, fileOrBuffer)
NodeID3.update(tags, fileOrBuffer)
NodeID3.create(tags)
NodeID3.read(filepath)
NodeID3.removeTags(filepath)
