What is node-ipc?

The node-ipc package is a Node.js module that provides a simple and flexible way to handle inter-process communication (IPC) in Node.js applications. It supports various types of communication, including local sockets, TCP, and UDP, making it suitable for a wide range of use cases such as microservices, distributed systems, and real-time applications.

What are node-ipc's main functionalities?

Local Socket Communication

This feature allows for communication between processes on the same machine using local sockets. The code sample demonstrates setting up a server that listens for messages and a client that sends and receives messages.

const ipc = require('node-ipc');

ipc.config.id = 'world';
ipc.config.retry = 1500;
ipc.config.silent = true;

ipc.serve(() => {
  ipc.server.on('message', (data, socket) => {
    ipc.log('Received message: ', data);
    ipc.server.emit(socket, 'message', 'Hello from server!');
  });
});

ipc.server.start();

// Client
ipc.connectTo('world', () => {
  ipc.of.world.on('connect', () => {
    ipc.log('Connected to world');
    ipc.of.world.emit('message', 'Hello from client!');
  });

  ipc.of.world.on('message', (data) => {
    ipc.log('Received message: ', data);
  });
});

TCP Communication

This feature enables communication over TCP, allowing processes to communicate over a network. The code sample shows how to set up a TCP server and a client that can send and receive messages.

const ipc = require('node-ipc');

ipc.config.id = 'tcpServer';
ipc.config.retry = 1500;
ipc.config.networkPort = 8000;
ipc.config.silent = true;

ipc.serveNet(() => {
  ipc.server.on('message', (data, socket) => {
    ipc.log('Received message: ', data);
    ipc.server.emit(socket, 'message', 'Hello from TCP server!');
  });
});

ipc.server.start();

// Client
ipc.connectToNet('tcpServer', 8000, () => {
  ipc.of.tcpServer.on('connect', () => {
    ipc.log('Connected to TCP server');
    ipc.of.tcpServer.emit('message', 'Hello from TCP client!');
  });

  ipc.of.tcpServer.on('message', (data) => {
    ipc.log('Received message: ', data);
  });
});

UDP Communication

This feature supports communication over UDP, which is useful for applications that require low-latency communication. The code sample demonstrates setting up a UDP server and a client that can send and receive messages.

const ipc = require('node-ipc');

ipc.config.id = 'udpServer';
ipc.config.retry = 1500;
ipc.config.networkPort = 8001;
ipc.config.silent = true;

ipc.serveUDP(() => {
  ipc.server.on('message', (data, socket) => {
    ipc.log('Received message: ', data);
    ipc.server.emit(socket, 'message', 'Hello from UDP server!');
  });
});

ipc.server.start();

// Client
ipc.connectToUDP('udpServer', 8001, () => {
  ipc.of.udpServer.on('connect', () => {
    ipc.log('Connected to UDP server');
    ipc.of.udpServer.emit('message', 'Hello from UDP client!');
  });

  ipc.of.udpServer.on('message', (data) => {
    ipc.log('Received message: ', data);
  });
});
