Discobot

A commandless Discord bot that streams an internet radio station (SHOUTcast, Icecast or any direct audio URL) into a voice channel around the clock. On start it joins the configured channel, plays the first entry of the list and posts "now playing" to a text channel. A bundled cron script restarts it on schedule, because the Discord voice API tends to go silent after 20 to 30 hours of uptime.

Requirements

Node.js with npm and FFmpeg on the PATH, or Docker.

Installation

git clone https://github.com/leinstay/discobot.git
cd discobot
npm install

With Docker, make build builds the image with FFmpeg included and make start runs it with the repository mounted.

Running

node index.js

For non-stop broadcasting use a process manager and the bundled restart.js cron job:

pm2 start index.js --name DiscoBot --log bot.log --time --restart-delay 5000
pm2 start restart.js --name Restart

Configuration

The bot reads config.json in the repository root. To get a channel ID, enable developer mode in Discord and right-click the channel.

Key	Meaning
token	Discord bot token
voicechannel	ID of the voice channel to stream into
logchannel	ID of the text channel for "now playing" messages
activity	Text shown as the bot's activity
prefix	Command prefix. Reserved, the bot has no commands
list	Array of { "name", "url" } entries, stations or audio files

{
  "prefix": "!a",
  "token": "{BOT TOKEN}",
  "voicechannel": "{VOICE CHANNEL ID}",
  "logchannel": "{TEXT CHANNEL ID}",
  "activity": "Anime Radio",
  "list": [
    { "name": "Anime Radio", "url": "https://pool.anison.fm/AniSonFM(320)?nocache=0.05" }
  ]
}

Several entries make a playlist. Any direct link to an MP3 works, so the same config can play audiobooks or albums.
