nssocket Comprehensive Guide to Enhance Your Node js Networking Applications

Introduction to nssocket

nssocket is a robust and simple framework for building TCP clients and servers in Node.js. With nssocket, developers can easily handle event-driven networking to build scalable and reliable messaging systems, chat applications, and more.

Basic API Reference and Examples

Creating a Server

  
    const nssocket = require('nssocket');

    const server = nssocket.createServer(function (socket) {
        socket.send(['hi'], 'Hello World!');
    });

    server.listen(6785);
    console.log('Server is listening on port 6785');
  

Creating a Client

  
    const nssocket = require('nssocket');

    const socket = new nssocket.NsSocket({
        reconnect: true
    });

    socket.connect(6785);

    socket.on('data', function (data) {
        console.log('Received: ' + data);
    });

    socket.send(['message'], 'Hello Server!');
  

Event Handling

  
    const nssocket = require('nssocket');

    const server = nssocket.createServer(function (socket) {
        socket.on('greeting', function (data) {
            console.log('Greeting received:', data);
            socket.send(['response'], 'Hello Client!');
        });
    });

    server.listen(6785, function() {
        console.log('Server is running on port 6785');
    });
  

Broadcasting Messages

  
    const nssocket = require('nssocket');

    const server = nssocket.createServer(function (socket) {
        setInterval(function() {
            socket.send(['news'], 'Breaking News!');
        }, 5000);
    });

    server.listen(6785);
  

Advanced Example

Below is an example of a simple chat application using the APIs discussed above.

Server for Chat Application

  
    const nssocket = require('nssocket');

    const clients = [];

    const server = nssocket.createServer(function (socket) {
        clients.push(socket);

        socket.on('message', function (data) {
            console.log('Message received: ' + data);
            clients.forEach(client => {
                if (client !== socket) {
                    client.send(['chat'], data);
                }
            });
        });

        socket.on('close', function () {
            const index = clients.indexOf(socket);
            if (index !== -1) {
                clients.splice(index, 1);
            }
        });
    });

    server.listen(6785, function () {
        console.log('Chat server running on port 6785');
    });
  

Client for Chat Application

  
    const nssocket = require('nssocket');

    const socket = new nssocket.NsSocket();

    socket.connect(6785);

    socket.on('chat', function (data) {
        console.log('Chat message: ' + data);
    });

    process.stdin.on('data', function (data) {
        socket.send(['message'], data.toString().trim());
    });
