WebPEER

Decentralized P2P network overlay in browser-side

WebPEER js library enables p2p connectivity without a central server in browser-side. Instant build completely peer-to-peer network embeded in your web applications with scalable peers, no trackers or relay servers required. Connecting projects safely, privately, and reliably in the global WebPEER Network.

Basic Chat App Demo available at : https://nuzulul.github.io/webpeerjs/demo/chat.html

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.

Quickstart

Try now in Playground :

https://jsbin.com/suwesaliro/1/edit?html,output

NPM install:

npm i webpeerjs

Browser <script> tag :

Uses built-in JS files from latest release or CDN will make it's exports available as webpeerjs in the global namespace.

<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/umd/webpeerjs.min.js"></script>

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, example : [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.
