Simple lightweight package to start your own
liveradio station 📻 Just drop yourmp3files and broadcast them to the world 🌎Heavily inspired by Shoutcast and Icecast.
npm i @fridgefm/radio-core --save
const { Station } = require('@fridgefm/radio-core');
const station = new Station();
station.addFolder('User/Music');
server.get('/stream', (req, res) => {
station.connectListener(req, res);
});
station.start();<audio

type='audio/mp3'
src='/stream'
/>Creating a station is as simple as
const myAwesomeStation = new Station({
verbose: false, // if true - enables verbose logging (for debugging purposes),
responseHeaders: { // in case you want custom response headers for your endpoint
'icy-genre': 'jazz'
}
})connectListener connects real users to your station, this is the only method that should be exposed to listeners
response argument is required
station.connectListener(request, response, callback);addFolder adds track within a folder to the playlist
station.addFolder('User/Music');start starts broadcasting
station.start();next instantly switches track to the next one
station.next();getPlaylist just returns you the entire playlist
station.getPlaylist();reorderPlaylist lets you manipulate the entire playlist via passed callback
const myShuffleMethod = (list) => list
// doubles the list (making it twice as long)
.concat(list)
// filters out the specific track
.filter(track => track.fsStats.name !== 'Artist - Track');
station.reorderPlaylist(myShuffleMethod);There are also some built-in shuffle methods
const { SHUFFLE_METHODS } = require('@fridgefm/radio-core')
// This one randomly shuffles the playlist (keeping the length the same)
station.reorderPlaylist(SHUFFLE_METHODS.randomShuffle());
// This one moves the track on the 1st position and moves it to the 2nd position
station.reorderPlaylist(SHUFFLE_METHODS.rearrange({ from: 1, to: 2 }));on lets you make a subscription to station events (see below)
Station emits several events - they are available via
const { PUBLIC_EVENTS } = require('@fridgefm/radio-core')event fires when track changes
useful for getting to know when exactly the track changed and what track that is
station.on(PUBLIC_EVENTS.NEXT_TRACK, (track) => {
const result = await track.getMetaAsync();
console.log(result)
})Event fires on station start
station.on(PUBLIC_EVENTS.START, () => { console.log('Station started') });Event fires on station restart (when playlist is drained and new one is created)
it might be a nice time to shuffle your playlist for example
station.on(PUBLIC_EVENTS.RESTART, () => { /* do something*/ });Event fires when there is some error. You should add this handler - otherwise any error will be treated as unhandled (causing process.exit depending on Node version)
station.on(PUBLIC_EVENTS.ERROR, (e) => { handleError(e) });or just go to examples
npm run start
or
npm run start [path/to/your_mp3tracks]
# in this case it would take a little more time, just wait
