dircc

Detachable, persistent IRC connection.

The actual connection to the server runs in a detached process, making it possible to reload your IRC client without breaking the connection to the server.

It uses an ircc Connection internally, which only handles the connection, not the communication. It doesn't respond to PINGs, doesn't send NICK and USER at the start of the session, et cetera.

Example

var dircc = require('dircc');

dircc.createConnection('ircc.sock', function(client) {
  client.on('init', function() {
    // called if there is no connection yet, so create one:
    client.connect(6667, 'irc.example.com');
    client.on('connect', function() {
      // registration:
      client.send('NICK', 'MyBoy');
      client.send('USER', 'mybot', 0, 0, 'My Awesome Bot');
    });
  });
  client.on('message', function(message) {
    console.log(message);
    if (message.command === 'WELCOME') {
      client.send('JOIN', '#channel');
    }
  });
});

API

dircc(filename, function(client) {})

dircc.createConnection(filename, function(client) {})

Creates a new ConnectionClient and connects it to the ConnectionServer via the unix socket at filename. If there is no server yet, it will be spawned.

The callback is optional and will be called when the ConnectionClient is ready.

Returns an eventemitter:

var connectionEmitter = dircc('irc.sock');
connectionEmitter.on('client', function(client) {
  /* ... */
});

connectionEmitter.on('client', function(client) {})

Emitted when the ConnectionClient is ready.

connectionEmitter.on('error', function(error) {})

Emitted when there's a problem with the ConnectionServer.

dircc.ConnectionClient

Connects to the ConnectionServer via the unix socket at filename:

var client = new ircc.ConnectionClient(filename);

client.connect(...)

Calls the server's .connect(...) method.

client.close()

Calls the server's .close() method.

client.send(...)

Calls the server's .send(...) method.

client.on('message', function(message) {})

Emitted when the ConnectionServer receives a message from the IRC server. The message is the same as you would expect from an ircc Connection or from the ircp parser.

client.on('connect', function() {})

Emitted when the ConnectionServer has a working Connection to the IRC server.

Important: this event is also emitted when connecting to an existing server with an existing Connection. Therefore it does not imply a "freshly made" connection.

client.on('init', function() {})

Emitted when connected to a ConnectionServer that doesn't have a Connection to an IRC server yet. This is, in essence, a prompt to call client.connect(...):

dircc.ConnectionServer

Manages a Connection and offers an API to communicate with it via a unix socket (using dnode).

var server = new ircc.ConnectionServer();

server.listen(filename)

Start listening to the unix socket at filename. If it already exists and can be connected to, the server will emit 'superfluous' and stop.

server.connect(port, host)

Create and open Connection to IRC server at host:port.

server.close()

Close the Connection.

server.send(messageObject)

server.send(command, [parameters...])

Send an IRC message. See Connection.

server.on('listening', function() {})

Emitted after the ConnectionServer starts listening for clients on the unix socket.

server.on('connect', function() {})

Emitted after the Connection to the IRC server is created and open.

server.on('superfluous', function() {})

Emitted if there's already a server running on the given unix socket.

server.on('error', function(error) {})

Emitted when there's a problem with the unix socket server.

server.on('close', function() {})

Emitted after the unix socket has been closed.
