WebPEER

Decentralized P2P network overlay inside browser

WebPEER.js enables browser to browser connectivity without a central server. Build completely peer-to-peer web applications, no trackers or relay servers required. Connecting projects safely, privately, and reliably in WebPEER Network.

Security

WebPEER Network run over libp2p gossipsub protocol to enables communication between peers.

By default, the gossipsub implementation will sign all messages with the author’s private key, and require a valid signature before accepting or propagating a message further. This prevents messages from being altered in flight, and allows recipients to authenticate the sender.
However, as a cooperative protocol, it may be possible for peers to interfere with the message routing algorithm in a way that disrupts the flow of messages through the network.

Example

import { webpeerjs } from 'webpeerjs'

void async function main() {

	const node = await webpeerjs.createWebpeer()
	
	console.log(`My node id : ${node.id}`)
	
	const [broadcast,listen,onmembersupdate] = node.joinRoom('globalroom')
	
	listen((message,id) => {
		console.log(`Message from ${id} : ${message}`)
	})
	
	onmembersupdate((data) => {
		console.log(`Members : ${data}`)
		broadcast('hello')
	})
	
}()

API

createWebpeer(config) - Create a new node. - config - Configuration object contain: - rtcConfiguration - (optional) Custom rtcConfiguration for WebRTC transport, currently the only transport available for direct peer-to-peer connectivity between browser.
id - Get the unique ID of the node as an identity in the global network.
status - Get the node status, returns connected or unconnected.
peers - Get all connected peers.
joinRoom(namespace) - Join to the room, returns an array of three functions (Broadcaster, onListenBroadcast, onMembersUpdate). - Broadcaster - Function to broadcast message to room members (limited to 1 message/second). - onListenBroadcast - Callback function that listen on incoming broadcast message. - onMembersUpdate - Callback function that listen on room members update.
