rbox is a high-performance Rust library for seamlessly interacting with Pioneer DJ's Rekordbox software data. It supports the following Rekordbox files:

• Rekordbox database: Query and update the Rekordbox v6/v7 master.db database through a type-safe ORM
• One Library: Read and write Rekordbox One Library (Device Library Plus) export files
• XML database: Read and write Rekordbox XML database files
• Analysis Files: Read and write ANLZ files containing waveforms, beat grids, hot cues and more
• Settings Access: Read and write My-Setting files

🔧 Installation

rbox-js is available on npm:

npm install rbox-js

or

yarn add rbox-js

🚀 Quick-Start

❗ Caution: Please make sure to back up your Rekordbox collection before making changes to rekordbox data. The backup dialog can be found under "File" > "Library" > "Backup Library"

Rekordbox 6/7 database

Rekordbox 6 and 7 use a SQLite database for storing the collection content. Unfortunatly, the master.db SQLite database is encrypted using SQLCipher, which means it can't be used without the encryption key. However, since your data is stored and used locally, the key must be present on the machine running Rekordbox.

rbox can unlock the new Rekordbox master.db SQLite database and provides an easy interface for accessing and updating the data stored in it.

import { MasterDb } from 'rbox-js'

const db = MasterDb.open();
const contents = db.getContents();
for (const content of contents) {
    console.log(content)
}

One Library (Device Library Plus)

For newer generation Pioneer DJ devices, Rekordbox exports a new library format to the USB storage device (or SD card), called One Library (formerly known as Device Library Plus). As of 2025, this format is only supported by the OPUS-QUAD, OMNIS-DUO, XDJ-AZ and CDJ-3000X devices. The database schema is similar to the main Rekordbox database. It contains a selection of tables from the main database, with similar columns and data types.

rbox can unlock the new Rekordbox exportLibrary.db One Library database and provides an easy interface for accessing the data stored in it:

import { OneLibrary } from 'rbox-js'

const db = new OneLibrary("exportLibrary.db");
const contents = db.getContents();
for (const content of contents) {
    console.log(content)
}

Rekordbox XML

The Rekordbox XML database is used for importing (and exporting) Rekordbox collections including track metadata and playlists. They can also be used to share playlists between two databases.

rbox can read and write Rekordbox XML databases.

import { RekordboxXml } from 'rbox-js'

const xml = RekordboxXml.load(path);
for (const track of xml.getTracks()) {
    console.log(`track: ${track}`);
}

Rekordbox ANLZ files

Rekordbox stores analysis information of the tracks in the collection in specific files, which also get exported to decives used by Pioneer professional DJ equipment. The files have names like ANLZ0000 and come with the extensions .DAT, .EXT or .2EX. They include waveforms, beat grids (information about the precise time at which each beat occurs), time indices to allow efficient seeking to specific positions inside variable bit-rate audio streams, and lists of memory cues and loop points.

rbox can parse and write all three analysis files.

import { Anlz } from 'rbox-js'

const anlz = new Anlz(path);
const beat_grid = anlz.getBeatGrid();sett.setQuantize(Quantize.Off);
for (const beat of beat_grid.beats) {
    console.log(`Beat: ${beat.beatNumber} Tempo: ${beat.tempo} Time: ${beat.time}`);
}

Rekordbox My-Settings

Rekordbox stores the user settings in *SETTING.DAT files, which get exported to USB devices. These files are either in the PIONEERdirectory of a USB drive (device exports), but are also present for on local installations of Rekordbox 6. The setting files store the settings found on the "DJ System" > "My Settings" page of the Rekordbox preferences. These include language, LCD brightness, tempo fader range, crossfader curve and other settings for Pioneer professional DJ equipment.

rbox supports both parsing and writing of My-Setting files.

import { Setting, Quantize } from 'rbox-js'

const sett = new Setting(path);
console.log(`Quantize: ${sett.getQuantize()}`);
sett.setQuantize(Quantize.Off);
sett.dump();
