websocket-because-yes

This repository contains implementation of The WebSocket Protocol.

Necesarry liblaries:

Only numpy :) (tested on 1.26.4)

This repository contains:

• Basic server that listens on 127.0.0.1:5006 and can recievie data via WebSocket
• WebSocket class (that currently can recieve non-fragmented messages)

Usage:

Demonstration:

Run server.py file:

python3 -m src.server

From (for example) console in web browser connect to the server:

const socket = new WebSocket("ws://localhost:5006/websocket");

Try sending messages to the server:

socket.send('test');
...
socket.send(125);

The WebSocket also correctly interprets binary data:

socket.send(new Uint8Array([72, 101, 108, 108, 111]));

The server very robustly logs connections and recieved messages :)

---

Other way to test the implementation is to use `test_client.py`

Usage:

1. run server.py

python3 -m src.server

2. from another terminal run test_client.py

python3 -m src.test_client

3. type in terminam any command:
   • P <message up to 125B >-> ping
   • C -> close connection
   • T -> text message
   • B <binary list of format 0-255,0-255,...> -> I think one could guess (send binarry message)

Tests:

Tests are implemented with unittest, to start them:

python3 -m unittest discover test -p "test_*.py"
