toy-peers

Simple network for Peer-To-Peer simulations which provides all mechanisms to build a low-level peer-to-peer network.

toy-peers relies on websockets to connect peers and exchange messages. Handshakes and offers are performed using Json Web Tokens.

Installation

npm install toy-peers --save

Getting started

Let's create a simple network with two peers connected to each other.

const Peer = require('toy-peers').Peer;

// peerA will run on port 80801, and peerB on port 8081
const peerA = new Peer(8080);
const peerB = new Peer(8081);

// launch peers
peerA.init();
peerB.init();

// listen for messages received from other peers
peerA.on('data', (id, message) => {
	console.log('peerA: received message "' + message + '" from peer#' + id);
});

peerB.on('data', (id, message) => {
	console.log('peerB: received message "' + message + '" from peer#' + id);
	peerB.send(id, 'hello world to you too!');
});

// connect peerA and peerB and then send a message
peerA.connect(peerB.address)
.then(() => peerB.connect(peerA.address))
.then(() => {
	// you can send data of any valid JS type (integer, string, Object, etc)
	peerA.send(peerB.id, 'hello world!');
})
.catch(err => console.err('failed to connect: ' + err));
