Understanding nssocket and Its Powerful API for Node.js Networking

Introduction to nssocket

Nssocket is a powerful networking library for Node.js that simplifies the process of building TCP-based network applications. It provides a robust API for creating both client and server applications, handling complex socket communication elegantly.

Basic Example

  const nssocket = require('nssocket');
  
  const server = nssocket.createServer((socket) => {
    console.log('A new socket connected!');
    
    socket.data('news::flash', (data) => {
      console.log('Message from client:', data.message);
    });

    socket.send('greeting', { message: 'Hello from server!' });
  });

  server.listen(6785);
  
  const client = new nssocket.NsSocket();
  
  client.connect(6785);

  client.data('greeting', (data) => {
    console.log('Message from server:', data.message);
    
    client.send('news::flash', { message: 'Hello from client!' });
  });

Event Handling

  socket.on('start', () => {
    console.log('Socket has started!');
  });

  socket.on('end', () => {
    console.log('Socket has ended!');
  });

  socket.on('error', (err) => {
    console.error('Socket encountered an error:', err);
  });

Sending and Receiving Data

  socket.send('message::name', { field: 'data' });

  socket.data('message::name', (data) => {
    console.log('Received data:', data.field);
  });

Streaming Data

  const stream = socket.stream('data::stream');

  stream.write('Initial data');
  stream.end('Final data');

  stream.on('data', (chunk) => {
    console.log('Received chunk:', chunk.toString());
  });

  stream.on('end', () => {
    console.log('Stream has ended');
  });

Service Example

  const nssocket = require('nssocket');

  const serviceServer = nssocket.createServer((socket) => {
    socket.send('weather::update', { status: 'sunny' });

    socket.data('weather::request', () => {
      socket.send('weather::response', { status: 'sunny' });
    });
  });

  serviceServer.listen(6790);

  const serviceClient = new nssocket.NsSocket();

  serviceClient.connect(6790);

  serviceClient.data('weather::update', (data) => {
    console.log('Weather update:', data.status);
  });

  serviceClient.send('weather::request');

  serviceClient.data('weather::response', (data) => {
    console.log('Weather response:', data.status);
  });

Overall, nssocket is an excellent choice for building robust and scalable network applications using Node.js. Its API simplifies socket communication and offers powerful features for event handling and data streaming.
