Node.js radio mini

Description

This app is a radio streaming solution made entirely in Node.js. It features a terminal GUI (there are sections for the playlist, the song queue, the currently playing song and for the keyboard controls) and a http endpoint at which the songs are going to get streamed.

Purpose of the whole project was to have fun and experiment. Production ready radio server should use Shoutcast / Icecast (or similar) for a robust streaming server.

Requirements

You must have ffprobe installed, which is part of ffmpeg, on your operating system in order for this app to work, since the javascript code relies on that binary to exist.

Installation

Clone this repository. Go into the root and run:

> npm install
> npm link

These commands will make a node-radio-mini command available to be run from anywhere in your terminal.

Usage

Go into a directory that contains music files (for now only mp3 format is supported), and run the command node-radio-mini.

> node-radio-mini

That command is going to read all mp3 files from the current directory and display them on you favorite terminal, similarly like on the image below.

There are four windows. 'Playlist' windows contains all the songs from you current directory. 'Queue' windows contains all queued up and ready to play songs. 'Now playing' windows is showing currently streamed song. 'Controls' window is just a helper for seeing available controls at that point of time.

First song is going to get automatically queued up and played. Songs are streamed to the endpoint http://process.env.HOST:process.env.PORT/stream, or if you didn't set any env variables the default would be http://localhost:8080/stream.

If you don't have any songs queued up, the last song will be played again.

This app is also serving a single html page that will automatically connect to the streaming endpoint shown above. The page is served at http://localhost:8080. You can see how the page looks in the browser in the next screenshot:
