P2P WebSocket Network Example

This project demonstrates how to create a peer-to-peer (P2P) network over a WebSocket infrastructure using Rust and the Tokio async runtime. The example code allows nodes to connect to each other, forming a distributed network where messages can be exchanged between peers.

Features

• Establish a P2P network using WebSockets.
• Support for both client and server WebSocket connections.
• Broadcast messages to all connected peers.
• Graceful shutdown on receiving Ctrl+C.

Dependencies

This project uses the following Rust crates:

• tokio: For asynchronous programming and handling I/O operations.
• tokio-tungstenite: For WebSocket client and server implementation.
• futures: For handling asynchronous streams and sinks.
• clap: For parsing command-line arguments.
• log: For logging information and errors.
• env_logger: For configuring the log output.

Running

Ensure you have Rust and Cargo installed on your system. Clone the repository and navigate to the project directory:

$ git clone https://github.com/mohyfahim/p2pws-rs.git
$ cd p2pws-rs
$ cargo build

Then in separate sessions, run the program in orders with the following arguments:

$ RUST_LOG=debug cargo run -- --bind localhost:8080

$ RUST_LOG=debug cargo run -- --peers ws://localhost:8080 --bind localhost:8085

$ RUST_LOG=debug cargo run -- --peers ws://localhost:8080,ws://localhost:8085 --bind localhost:8086

Then you can see the message, broadcasting from each peer to all others. all-to-all broadcast!
