Intro to NodeJS - using the net module and building a client and server

client.js

const net = require('net');

const options = {
  'port': 8080,
  'host': '127.0.0.1'
};

// creates a socket connection to a server
const client = net.connect(options, () => {
  console.log('Connected to Server!');
  client.write('Hello server');
});

// handles data received
client.on('data', (data) => {
  console.log('data: ', data);
});

// Take input from the commandline
process.stdin.on('readable', () => {
  var chunk = process.stdin.read();
  if (chunk !== null) {
    client.write(chunk)
  }
});

server.js

const net = require('net');

const server = net.createServer((request) => {
  // handles data received
  request.on('data', (data) => {
    console.log('Request recieved /n', data.toString());
  })

  request.write('Hello Client');
  request.end();

  // Handles request ended
  request.on('end', () => {
    console.log('Connection Closed');
  })
})

// Listen for events on port 8080
server.listen({ port: 8080 }, () => {
  const address = server.address();
  console.log(`Opened server on ${address.port}`)
});
