Communication

The Server-Client communication is via the smart_socket:

import json
import socket


class Socket:
    """
    Socket enhancement to enable sending unlimited-size messages and using the json module.
    """
    def __init__(self, sock: socket.socket):
        self.socket = sock

    def send(self, data) -> None:
        data = json.dumps(data).encode()

        self.socket.sendall(data)
        self.socket.send(b"<done>")

    def receive(self):
        data = b""
        while not data.endswith(b"<done>"):
            data += self.socket.recv(1024)
        data = data[:-6]

        return json.loads(data)

    def execute(self, command):
        self.send(command)
        return self.receive()

Which uses pickle to serialize JSON objects and send it to the client.

UI

The user interface was done using PyQt5.

The authentication design was inspired by Zoom software for desktop.

Responsive design, the main window is fully resizable.
