This library implments the Pioneer PROLINK network protocol + additional functionality to interact with the prolink network. This library is used as part of Prolink Tools.
Alternative implementations of the Prolink protocol: Java, golang.
Thank you to @brunchboy for his work on dysentery.
Written in Typescript - Accurate typings making implementation a breeze. Autocompete your DJ tools to completion.
CDJ Status - Receive Player state details for each CDJ on the network.
The status is reported as a CDJStatus.State
.
Metadata Database - Access metadata of currently the currently playing (or not!) tracks stored in the connected Rekordbox formatted USB / SD device, or via Rekordbox link.
To talk with Prolink devices on the network you'll first need to...
import {bringOnline} from 'prolink-connect';
async function main() {
// Bring the prolink network online.
//
// This will begin listening for prolink devices on the network that send
// regular announcment packets over UDP.
//
// This will FAIL if Rekordbox is running on the same computer, or a second
// instance of the prolink-connect library is running on the same machine.
console.info('Bringing the network online');
const network = await bringOnline();
// Once online we can listen for appearning on the network
network.deviceManager.on('connected', device =>
console.log('New device on network:', device)
);
// To configure the online network to be "connected" we must need to specify
// what network device to use to announce ourselves as a "virtual" device
// onto the network, and what ID we want to announce ourselves as. By
// announcing ourselves this will cause other devices to send us more detailed
// information.
//
// There are two ways to configure the network:
//
// 1. Automatically - You can ask prolink-connect to wait for a device to
// appear on the network to determine what network interface devices exist
// on. Device ID 5 will be used in auto configure mode.
//
// 2. Manually - In this case you will need to manually specify the network
// device and device ID.
//
// NOTES on the Device ID:
//
// It's recommended that you use a Device ID of `5` for the virtual device.
// Using a ID between 1 - 6 will take up ONE SLOT on the network that normally
// a CDJ would occupy. When a 1-6 ID is used You may ONLY HAVE 5 CDJs on the
// network. Attempting to connect a 6th CDJ will conflict with the virtual
// device announced on the network by prolink-connect. (On models older than
// 2000s the rande is 1-4.)
//
// There are some cases where you may want your virtual device to announce
// itself with "real" device ID, but this library does not currently support
// the scenarios that would requrie that (Becoming master and sending a master
// tempo)
// 1. AUTO CONFIGURATION
console.info('Auto configuring the network');
await network.autoconfigFromPeers();
// 2. MANUAL CONFIGURATION
//
// const configuredIface = getNetworkInterfaceInfoIPv4()
// network.configure({vcdjId: 2, iface: configuredIface})
// We can now connect to the network.
//
// This will begin announcing ourself on the network, as well as enable various
// services on the network service object.
console.info('Connecting to the network');
await network.connect();
// If you're using trypescript, you can now type guard [0] to coerce the type
// to ProlinkNetworkConnected, marking all services as non-null.
//
// [0]: https://www.typescriptlang.org/docs/handbook/advanced-types.html#using-type-predicates
//
// You don't need to do this if you're not using trypescript
if (!network.isConnected()) {
console.error('Failed to connect to the network');
return;
