A server for the Friendly Audio Streaming Protocol.

Use fasp-server-cli if you want to run a server from the command line.

Because fasp-server is based on the wonderful mpv, it can play audio from many sources.

Install mpv. Refer to their installation page for further details.

# macOS
brew install mpv
# Ubuntu or similar
sudo add-apt-repository ppa:mc3man/mpv-tests
sudo apt update
sudo apt install mpv

On many Linux systems, you also need the dns_sd.h headers for mDNS.

# Ubuntu or similar
sudo apt install libavahi-compat-libdnssd-dev

Then, install fasp-server.

npm install fasp-server


const createServer = require('fasp-server')

const server = createServer((err, info) => {
    if (err) {
        process.exitCode = 1
    } else {
        console.info('port', info.port)

Control the server programmatically using fasp-client, or from the command line using fasp-client-cli.
