What is unix-dgram?

The unix-dgram npm package provides a way to create and manage Unix domain datagram sockets in Node.js. This allows for inter-process communication (IPC) on the same host using the Unix domain socket protocol.

What are unix-dgram's main functionalities?

Creating a Unix Datagram Socket

This feature allows you to create a Unix datagram socket and bind it to a specific path. This is useful for setting up a communication endpoint for IPC.

const dgram = require('unix-dgram');
const socket = dgram.createSocket('unix_dgram');
socket.bind('/tmp/socket');
console.log('Socket bound to /tmp/socket');

Sending Messages

This feature allows you to send messages through the Unix datagram socket. The code sample demonstrates sending a simple 'Hello, World!' message to a specified socket path.

const dgram = require('unix-dgram');
const socket = dgram.createSocket('unix_dgram');
socket.send(Buffer.from('Hello, World!'), 0, 12, '/tmp/socket', (err) => {
  if (err) console.error(err);
  else console.log('Message sent');
});

Receiving Messages

This feature allows you to receive messages sent to the Unix datagram socket. The code sample shows how to set up an event listener for incoming messages and log them to the console.

const dgram = require('unix-dgram');
const socket = dgram.createSocket('unix_dgram');
socket.on('message', (msg, rinfo) => {
  console.log('Received message:', msg.toString());
});
socket.bind('/tmp/socket');
