Deno 2.2 Improves Dependency Management and Expands Node.js Compatibility
Deno 2.2 enhances Node.js compatibility, improves dependency management, adds OpenTelemetry support, and expands linting and task automation for developers.
A small Javascript wrapper for talking to the Janus WebRTC signalling API.
A super-simplistic and -minimal wrapper for talking to the Janus signalling API. Developed for use with
Janus as a web game networking backend via janus-plugin-sfu, but fundamentally plugin-agnostic. Designed to
provide useful possible abstractions while still providing the maximum possible control over RTCPeerConnection
configuration and precise plugin signalling flow.
If you want a batteries-included wrapper, you should use the one distributed by the Janus developers -- janus.js. This one is different in a few ways:
RTCPeerConnection
directly, whereas janus.js
wraps and manages the connection for you.If you want a similar but moderately more featureful wrapper, check out minnie-janus.
Require minijanus
in Node, or link to bundle.js in a browser. Then:
var ws = new WebSocket("ws://localhost:8188", "janus-protocol");
var session = new JanusPluginSession(ws.send.bind(ws));
var handle = new JanusPluginHandle(session);
var conn = new RTCPeerConnection({});
ws.addEventListener("message", ev => session.receive(JSON.parse(ev.data)));
ws.addEventListener("open", _ => {
session.create()
.then(_ => handle.attach("janus.plugin.sfu"))
.then(_ => {
conn.addEventListener("icecandidate", ev => {
handle.sendTrickle(ev.candidate || null).catch(e => console.error("Error trickling ICE: ", e));
});
conn.addEventListener("negotiationneeded", _ => {
var offer = conn.createOffer();
var local = offer.then(o => conn.setLocalDescription(o));
var remote = offer.then(j => handle.sendJsep(j)).then(r => conn.setRemoteDescription(r.jsep));
Promise.all([local, remote]).catch(e => console.error("Error negotiating offer: ", e));
});
var unreliableCh = conn.createDataChannel("unreliable", { ordered: false, maxRetransmits: 0 });
var reliableCh = conn.createDataChannel("reliable", { ordered: true });
navigator.mediaDevices.getUserMedia({ audio: true })
.then(m => m.getTracks().forEach(t => conn.addTrack(t, m)))
.catch(e => console.error("Error acquiring media: ", e));
return new Promise(resolve => handle.on("webrtcup", resolve));
})
.then(_ => { console.info("Connected to Janus: ", conn); })
.catch(e => { console.error("Error connecting to Janus: ", e); });
});
(Note that this example code first negotiates only the data channels, and then renegotiates afterward when the microphone permission is provided. Only recent versions of Janus support renegotiation. If you didn't want this, you would instead wait to create the connection until the microphone permission was granted.)
To generate bundle.js:
$ npm run build
$ npm test
