🎶 @tmigone/pulseaudio 🎶

@tmigone/pulseaudio is a TypeScript based client library for PulseAudio, the most popular sound server for Linux. This library allows you to easily build clients or applications that interact with a PulseAudio server over it's native protocol, for example media players/recorders, volume control applications, etc.

Features

• Zero dependency fully typed TypeScript implementation of the PulseAudio client protocol
• Extensive testing suite
• Protocol features:
  • authentication - provide authentication data for the server
  • transport - connect over UNIX domain sockets or TCP sockets
  • introspection - query, modify and operate on PulseAudio objects like modules, sinks, sources, etc.
  • events - subscribe to server-side object events like a sink starting playback, etc.
  • (To be implemented) streams - manage audio playback and recording using Node.js streams

Installation

Install the library using npm:

npm install @tmigone/pulseaudio

Usage

import PulseAudio, { Sink } from '@tmigone/pulseaudio'

(async () => {
  // Connect using tcp or unix socket
  // const client: PulseAudio = new PulseAudio('unix:/run/pulse/pulseaudio.socket')
  const client: PulseAudio = new PulseAudio('tcp:192.168.1.10:4317')
  await client.connect()

  // Set volume of all sinks to 50%
  const sinks: Sink[] = await client.getSinkList()
  for (const sink of sinks) {
    await client.setSinkVolume(sink.index, 50)
  }

  // Close connection
  client.disconnect()
})()
