v20.0.1

Multisocket Socket Library

An abstract multicast socket library designed to handle some of the platform specific implementation details that
make it difficult to write a cross platform multicast socket library.

Documentation

https://gibme-npm.github.io/multicast

Features

• IPv4 and IPv6 Support
• Windows, Linux, and Mac OS X Support
• Cross Platform
• Asynchronous
• Non-Blocking
• Supports Multicast and Unicast Messages
• Supports Joining and Leaving Multicast Groups
• Proper handling of listening on all interfaces
  • Creates a singular multicast socket for listening (or sending)
  • Creates a separate unicast socket for each interface for receiving unicast replies and/or sending messages (to ensure it goes out on all interfaces when bound to all)
• Ability to listen on one interface (by IP or name)
• Supports dynamic TTL
• Loopback support

Sample Code

import { MulticastSocket } from '@gibme/multicast';

(async () => {
    const socket = await MulticastSocket.create({
        port: 5959,
        multicastGroup: '224.0.0.251',
        loopback: true
    });
    
    socket.on('message', (message, remote, fromSelf) => {
        console.log({message, remote, fromSelf});
    })
    
    socket.send('Hello World');
});
