PeerJS: Simple peer-to-peer with WebRTC #

$3


PeerJS provides a complete, configurable, and easy-to-use peer-to-peer API built on top of WebRTC, supporting both data channels and media streams.

Setup

Include the library

with npm:
npm install peerjs
and the usage:
``js
import Peer from 'peerjs';
`


Create a Peer
`javascript
const peer = new Peer('pick-an-id');
// You can pick your own id or omit the id if you want to get a random one from the server.
`

Data connections


Connect
`javascript
const conn = peer.connect('another-peers-id');
conn.on('open', () => {
conn.send('hi!');
});
`
Receive
`javascript
peer.on('connection', (conn) => {
conn.on('data', (data) => {
// Will print 'hi!'
console.log(data);
});
});
`

Media calls

Call
`javascript
navigator.mediaDevices.getUserMedia({video: true, audio: true}, (stream) => {
const call = peer.call('another-peers-id', stream);
call.on('stream', (remoteStream) => {
// Show stream in some

`
Answer
`javascript
peer.on('call', (call) => {
navigator.mediaDevices.getUserMedia({video: true, audio: true}, (stream) => {
call.answer(stream); // Answer the call with an A/V stream.
call.on('stream', (remoteStream) => {
// Show stream in some `

Running tests

`bash
npm test
``
