lazy-socket 0.0.3

A lightweight WebSocket-based communication library

Lazy Socket

An attempt at creating a websocket based communication system that handles all the threading and async stuff in the background.

Installation

pip install lazy-socket

Usage

Server

The server can be created by subclassing LazyServer and implementing the process_message method. This is an async method that will be called whenever a message is received from a client. To respond to the client, use the send method of the client object passed to the method. A list of clients is available via the clients attribute of the server.

import asyncio
from lazy_socket.server import LazyServer


class Server(LazyServer):

    async def process_message(self, client, message):
        await client.send(f"Received: {message}")

if __name__ == "__main__":
    server = Server(name="TestServer", host="0.0.0.0", port=5000, version="1.0")

    try:
        server.start()
    except KeyboardInterrupt:
        print("Shutting down server...")

Client

The client can be created by instantiating the LazyClient class. The client has a queue attribute that can be used to receive messages from the server. The client must be started using the start method. Messages can be sent to the server using the send method.

A message lazy_client:connected:{uri} is sent to the queue when the client successfully connects to the server.

from lazy_socket.client import LazyClient

client = LazyClient()
client.start()

while True:
    if client.queue.empty():
        continue

    message = client.queue.get()
    if message.startswith("lazy_client:connected:"): 
        client.send("Hello, Lazy Server!")
