How to wrap a tcp socket connection between two servers in a promise?

Question

Node.js

There is an authorization and session storage server.
To simplify to a minimum:

const net = require('net');
const server = net.createServer((socket) => {
   socket.on('data', (data) => {
      //обрабатываем данные
      socket.write(data); //отправляем обработанные
      });
   socket.on('end', () => {});
});
server.listen(1333, () => {
  console.log('server bound');
});

And there are microprocesses that access the server for information:

const net = require('net');
const client = new net.Socket();
client.setEncoding('utf8');

client.connect('1333','0.0.0.1', ()=>{});
client.write(JSON.stringify({ param : data.toString()}));
client.on('data', (data) => {
   //обрабатываем полученные от сервера результаты
});

The question is, is it necessary to wrap the request of each client in a promise? And if so, how...

Answer 1

It can also be a regular callback. The main thing is that your logic is executed asynchronously.

Answer 2

It’s definitely not in the promise, since the promise works out and dies, and the sockets are still stream events, and not one-time
