yoil - yet (an)other irc library

yoil is a simple, yet fairly flexible IRC library written in JavaScript. It is intended for web-based IRC communication, and therefore only provides a WebSocket transport.

Features:

• Adaptive requesting of IRCv3 capabilities: some IRCv3 caps require other caps to actually be useful (I'm looking at you echo-message). Therefore, yoil checks if a capabilities dependants are present before requesting.
• SASL mechanisms: Since PLAIN is so easy to implement, I decided to implement SCRAM-SHA-256 and SCRAM-SHA-512 support (oh, and SCRAM-SHA-1, but don't use that)
• Namespaced events: Events are provided in namespaces depending on where the event belongs. The most interesting thing this does, is provide a way to distinguish between private messages and channel messages, using user::privmsg and channel::privmsg respectively.
• And a lot more, like auto reconnecting, automatically changing your nick if its in use, and a few other features.

Example:

Here is a simple example:

const irc = require('yoil');

const config = new irc.Config({
  nickname: 'nickname',
  username: 'username',
  realname: 'realname',
  
  port: 7002,
  host: '127.0.0.1',
  
  tls: true,
  
  saslUsername: 'username',
  saslPassword: 'password',

  autoReconnect: true,
});

const client = new irc.Client(config);

client.connect();

client.on('server::registered', ({ server }) => {
  console.log(`Connected to ${server}`);
});

client.on('sasl::account', ({ account, error }) => {
  if (error) {
    console.log('SASL unsuccessful');
  } else {
    console.log(`I successfully negotiated SASL and logged in as ${account}`);
  }
});

client.on('server::erroneous-nickname', data => {
  console.log(data);
});
