PeerServer helps broker connections between PeerJS clients. Data is not proxied through the server.
If you prefer to use a cloud hosted PeerServer instead of running your own, sign up for a free API key here
or
Install the library:
$> npm install peerRun the server:
$> peerjs --port 9000 --key peerjsOr, create a custom server:
var PeerServer = require('peer').PeerServer;
var server = PeerServer({port: 9000, path: '/myapp'});Connecting to the server from PeerJS:
<script>
// No API key required when not using cloud server
var peer = new Peer('someid', {host: 'localhost', port: 9000, path: '/myapp'});
</script>Using HTTPS: Simply pass in PEM-encoded certificate and key.
var fs = require('fs');
var PeerServer = require('peer').PeerServer;
var server = PeerServer({
port: 9000,
ssl: {
key: fs.readFileSync('/path/to/your/ssl/key/here.key'),
cert: fs.readFileSync('/path/to/your/ssl/certificate/here.crt')
}
});Make sure to set the proxied option, otherwise IP based limiting will fail.
The option is passed verbatim to the
expressjs trust proxy setting
if it is truthy.
var PeerServer = require('peer').PeerServer;
var server = PeerServer({port: 9000, path: '/myapp', proxied: true});var express = require('express');
var app = express();
var ExpressPeerServer = require('peer').ExpressPeerServer;
app.get('/', function(req, res, next) { res.send('Hello world!'); });
var server = app.listen(9000);
var options = {
debug: true
}
app.use('/api', ExpressPeerServer(server, options));
// OR
var server = require('http').createServer(app);
app.use('/peerjs', ExpressPeerServer(server, options));
server.listen(9000);The 'connection' event is emitted when a peer connects to the server.
server.on('connection', function(id) { ... });The 'disconnect' event is emitted when a peer disconnects from the server or
when the peer can no longer be reached.
server.on('disconnect', function(id) { ... });Discuss PeerJS on our Google Group: https://groups.google.com/forum/?fromgroups#!forum/peerjs
