Websocket chat example

This is a multi-threaded chat server example.

Fancy shiny features:

• Browser-based WebSocket client served from static html+js
• Chat server runs in separate thread
• Tcp listener runs in separate thread
• Application state is shared with the websocket server and a resource at /count/
• Uses actors for improved readability of code in the server.rs implementation

Server

1. Chat server listens for incoming tcp connections. Server can access several types of message:

• /list - list all available rooms
• /join name - join room, if room does not exist, create new one
• /name name - set session name
• some message - just string, send message to all peers in same room
• client has to respond to heartbeat Ping messages, if server does not receive a heartbeat 'Pong' message for 10 seconds connection gets dropped

2. http://localhost:8080/count/ is a non-websocket endpoint and will affect and display state.

To start server use command: cargo run --bin websocket-chat-server

WebSocket Browser Client

Open url: http://localhost:8080/ Use two tabs to set up a proper conversation.

Python Client using aiohttp

Client connects to server. Reads input from stdin and sends to server. Fetch the needed python libraries pip3 install --requirements requirements.txt Then start client as ./client.py
