slack-irc

Connects Slack and IRC channels by sending messages back and forth. Read more here.

Demo

Installation and usage

Either by installing through npm:

$ npm install -g slack-irc
$ slack-irc --config /path/to/config.json

or by cloning the repository:

In the repository folder:
$ npm install
$ node index.js --config /path/to/config.json

It can also be used as a node module:

var slackIRC = require('slack-irc');
var config = require('./config.json');
slackIRC(config);

Configuration

slack-irc uses Slack's bot users. This means you'll have to set up a bot user as a Slack integration, and invite it to the Slack channels you want it to listen in on. This can be done using Slack's /invite <botname> command. This has to be done manually as there's no way to do it through the Slack bot user API at the moment.

slack-irc requires a JSON-configuration file, whose path can be given either through the CLI-option --config or the environment variable CONFIG_FILE. The configuration file needs to be an object or an array, depending on the number of IRC bots you want to run.

This allows you to use one instance of slack-irc for multiple Slack teams if wanted, even if the IRC channels are on different networks.

To set the log level to debug, export the environment variable NODE_ENV as development.

slack-irc also supports invite-only IRC channels, and will join any channels it's invited to as long as they're present in the channel mapping.

Example configuration

[
  // Bot 1 (minimal configuration):
  {
    "nickname": "test2",
    "server": "irc.testbot.org",
    "token": "slacktoken2",
    "channelMapping": {
      "#other-slack": "#new-irc-channel"
    }
  },
 
  // Bot 2 (advanced options):
  {
    "nickname": "test",
    "server": "irc.bottest.org",
    "token": "slacktoken", // Your bot user's token
    "autoSendCommands": [ // Commands that will be sent on connect
      ["PRIVMSG", "NickServ", "IDENTIFY password"],
      ["MODE", "test", "+x"],
      ["AUTH", "test", "password"]
    ],
    "channelMapping": { // Maps each Slack-channel to an IRC-channel, used to direct messages to the correct place
      "#slack": "#irc channel-password", // Add channel keys after the channel name
      "privategroup": "#other-channel" // No hash in front of private groups
    },
    "ircOptions": { // Optional node-irc options
      "floodProtection": false, // On by default
      "floodProtectionDelay": 1000 // 500 by default
    },
    // Makes the bot hide the username prefix for messages that start
    // with one of these characters (commands):
    "commandCharacters": ["!", "."]
  }
]

ircOptions is passed directly to node-irc (available options).

Tests

Run the tests with:

$ npm test

Style Guide

slack-irc uses a slightly modified version of the Airbnb Style Guide. ESLint is used to make sure this is followed correctly, which can be run with:

$ npm run lint

The deviations from the Airbnb Style Guide can be seen in the .eslintrc file.
