run method

Future<void> run({ InternetAddress? address, int? port, int connectionCheckIntervalSeconds = 30, String? privateKeyPath, String? motdPath, })

Start a server.

address default is 0.0.0.0

port default is 6667

If privateKeyPath is not null, server listen with TLS enabled. It's file contents must contains both CERTIFICATE and PRIVATE KEY. So it's just looks like:

-----BEGIN CERTIFICATE-----
abcabc...
-----END CERTIFICATE-----
-----BEGIN PRIVATE KEY-----
xyzxyz...
-----END PRIVATE KEY-----

Implementation

Future<void> run({
  InternetAddress? address,
  int? port,
  int connectionCheckIntervalSeconds = 30,
  String? privateKeyPath,
  String? motdPath,
}) async {
  final addr = address ??
      InternetAddress(Platform.environment['IRCD_HOSTADDR'] ?? '0.0.0.0');
  final portStr = Platform.environment['IRCD_PORT'];
  final portNum = port ??
      (portStr != null ? int.tryParse(portStr, radix: 10) : null) ??
      6667;
  final certKeyPath =
      privateKeyPath ?? Platform.environment['IRCD_PRIVATE_KEY'];

  final ponger = Timer.periodic(
    Duration(seconds: connectionCheckIntervalSeconds),
    (_) => _checkClientConnection(DateTime.now()),
  );

  if (certKeyPath == null) {
    final server = await ServerSocket.bind(addr, portNum);
    _listen(server, ponger);

    print(banner);
    print('Listen on: ${server.address.address}:${server.port}');
  } else {
    final securityContext = SecurityContext()
      ..useCertificateChain(certKeyPath)
      ..usePrivateKey(certKeyPath);
    final server = await SecureServerSocket.bind(
      addr,
      portNum,
      securityContext,
    );
    _listen(server, ponger);

    print(banner);
    print('Listen on: ${server.address.address}:${server.port} with TLS');
  }
}
