Introduction to nssocket

nssocket is a powerful network communication library for Node.js, which simplifies the creation of client-server applications. It’s highly efficient and easy to use, making it an excellent choice for developers looking to implement robust communication protocols.

Key Features of nssocket

• Simplicity and ease of use
• Evented communication model
• Supports JSON messaging
• Flexible and extendible

Common API Methods

nssocket provides a variety of useful APIs. Below are some of the most commonly used methods along with their explanations and code snippets:

Creating a Server

  const nssocket = require('nssocket');

  const server = nssocket.createServer((socket) => {
    console.log('Connected to a new client');
  });

  server.listen(6785, () => {
    console.log('Server listening on port 6785');
  });

Creating a Client

  const nssocket = require('nssocket');

  const client = new nssocket.NsSocket();

  client.connect(6785);
  client.on('start', () => {
    console.log('Connected to the server');
  });

Sending Events

  const nssocket = require('nssocket');

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

  client.send(['hello', 'world'], { foo: 'bar' });

Receiving Events

  const nssocket = require('nssocket');

  const server = nssocket.createServer((socket) => {
    socket.data(['hello', 'world'], (data) => {
      console.log('Received:', data);
    });
  });

  server.listen(6785);

Disconnecting

  client.end();
  server.close();

Example Application

Below is a simple application that demonstrates the usage of the nssocket APIs:

  const nssocket = require('nssocket');

  // Create a server
  const server = nssocket.createServer((socket) => {
    console.log('User connected');
    
    socket.data(['message', 'send'], (data) => {
      console.log('Received message:', data.message);
      socket.send(['message', 'response'], { message: 'Message received!' });
    });

    socket.on('close', () => {
      console.log('User disconnected');
    });
  });

  server.listen(6785, () => {
    console.log('Server is listening on port 6785');
  });

  // Create a client
  const client = new nssocket.NsSocket();

  client.connect(6785);

  client.send(['message', 'send'], { message: 'Hello, server!' });

  client.data(['message', 'response'], (data) => {
    console.log('Server response:', data.message);
  });

  setTimeout(() => {
    client.end();
  }, 5000);

This example shows a simple message exchange between a server and a client using nssocket. The client sends a message to the server, which then responds back to the client.

nssocket is a versatile and powerful tool for network communication in Node.js applications, offering simplicity and flexibility.
