# node-id3
node-id3 is an ID3-Tag library written in JavaScript.
## Installation
```sh
npm install node-id3
```
## Usage
```javascript
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.
```javascript
const success = NodeID3.write(tags, filepath) // Returns true/Error
// async version
NodeID3.write(tags, file, function(err) { })
```
### Write tags to filebuffer
```javascript
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.
```javascript
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.
```javascript
const success = NodeID3.create(tags) // Returns ID3-Tag Buffer
// async version
NodeID3.create(tags, function(buffer) { })
```
### Reading ID3-Tags
```javascript
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
```javascript
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)
```javascript
const NodeID3Promise = require('node-id3').Promise
NodeID3.write(tags, fileOrBuffer)
NodeID3.update(tags, fileOrBuffer)
NodeID3.create(tags)
NodeID3.read(filepath)
NodeID3.removeTags(filepath)
```
