Controlling system volume level in Node.js has never been easier!

This cross-platform, dependency-free library lets you control and get the status of volume in your system. No matter what OS or what framework (it works everywhere - as well as on regular Node.js and Electron - where they were tested), you don't have to worry about the compatibility and potential errors - this library will handle it all.

Note that this library solves the Electron production-build specific problem with asar-packed files - other libraries similar to this, which have to call executable file or native module, don't work on Electron - easy-volume, on the other hand, was designed (and tested) to work with Electron like a charm!


import { setVolume, getVolume, setMute, getMute } from "easy-volume";

// Set volume - value from 0 to 100%
await setVolume(20);

// Get volume - value from 0 to 100%
const volume: number = await getVolume();
console.log(volume); // 20

// Set mute - true is muted and false is unmuted
await setMute(true);

// Get current mute status - true if system audio is muted, otherwise false
const isMuted: boolean = await getMute();
console.log(isMuted); // true


getVolume(): Promise<number>

  • Get current system volume
  • Returns: System volume, from 0 to 100 [%]

setVolume(targetValue: number) => Promise<void>

  • Change system volume to target value
  • Param targetValue: Target volume, from 0 to 100

getMute(): Promise<boolean>

  • Get current mute status (whether the system audio is muted or not)
  • Returns: Whether the system audio is muted, i.e. true == muted, false == unmuted

setMute(isMuted: boolean) => Promise<void>

  • Either mute or unmute system audio
  • Param isMuted: Whether to mute or unmute the system audio

toggleMute() => Promise<void>

  • Toggle mute state
  • Returns: Current (new) mute state (true == muted, false == unmuted)


This library should be compatible with every of the most popular OS:

  • Windows (uses native C++ CLI tool I wrote by myself (see src/platforms/windows/main.cpp))
  • macOS (uses AppleScript (osascript))
  • Linux (uses Advanced Linux Sound Architecture (ALSA, amixer) - installed by default on most Linux distros)

Tested on:

  • Windows 11 22H2
  • macOS Ventura 13.4
  • Ubuntu 22.04.2 LTS


You can test the library on your setup by running this command:

npm test

If any of the test fails or you're using another setup which isn't implemented here, feel free to create an issue or a pull request.

Feel free to give some ideas for future features by creating issues on the GitHub repository.


To build the library, just run simple

npm run build

IMPORTANT: After building, be sure to copy src/platforms/windows/volume.exe into dist/platforms/windows/volume.exe

Creating own implementations

If you're using a different setup and/or want to create your own implementation of the library, feel free to make a pull request.

  1. In src/platforms, create a new directory with the name of your target platform.
  2. In your newly created directory, create index.ts file which exports an object of type PlatformImplementation (see its declaration in src/types.ts).
  3. Create your custom implementation. Note: if you're calling some native modules or any files, make sure to surround your path with the toElectronPath function from src/utils/toElectronPath.ts.
  4. In the src/index.ts file, add a special case to the switch statement with your platform, following the patterns in the file.
  5. Before creating the pull request, please test the library (see above for running tests).
