Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@lunionlab/meet-client-js

SDK client web pour lunion.meet — connexion au SFU, publication et abonnement des pistes média via RTCPeerConnection standard (offer/answer sur WebSocket). Framework-agnostique, sans dépendance runtime.

1.0.0 : la classe cliente s'appelle LunionMeetClient, sur RTCPeerConnection standard. Depuis 0.1.x, SfuClient/loadDevice/createSendTransport/produce sont remplacés par LunionMeetClient. Voir « Migration » ci-dessous.

import { LunionMeetClient } from "@lunionlab/meet-client-js";

const client = new LunionMeetClient(
  { url: "wss://meet.lunion-lab.com/sfu", iceServers: [{ urls: "stun:stun.l.google.com:19302" }] },
  {
    onWelcome: ({ selfId, peers }) => console.log("connecté", selfId, peers.length, "pairs"),
    onPeerJoined: ({ peerId, name }) => console.log("arrivée", name),
    // Piste distante : `streams[0].id` = id du pair source. `onTrackMeta` distingue cam / écran / micro.
    onTrack: (track, streams, _receiver, _mid) => attachToVideoElement(streams[0], track),
    onTrackMeta: ({ mid, peerId, source }) => console.log(peerId, source), // "cam" | "mic" | "screen"
  },
);

// Résout le `welcome` (après admission si salle d'attente). `token` émis côté backend par
// @lunionlab/meet-server-sdk ; sans token = mode ouvert (hôte + salle d'attente).
const welcome = await client.connect("reunion-1", "Awa", /* cid */ undefined, token);

// Publier caméra (simulcast auto) + micro
await client.publishCamera();
await client.publishMic();

API essentielle

  • new LunionMeetClient({ url, iceServers? }, handlers?)
  • connect(room, name, cid?, token?): Promise<LunionMeetWelcome>
  • publishCamera(constraints?, { codec? }), publishMic(), publishTrack(track, stream, encodings?, codec?) (bas niveau) — codec = mimeType préféré, ex. "video/H264" (accélération matérielle mobile/Safari) ; 0.3.0+
  • setTrackSource(mid, "screen") — étiqueter une piste (partage d'écran) ; relayé aux pairs via onTrackMeta
  • startRecording(peerId?), stopRecording(recordingId?) (modérateur)
  • Actions plan de contrôle : chat/réaction, salle d'attente (admit/deny), modération, rôles
  • Handlers : onWelcome, onTrack, onTrackMeta, onPeerJoined/Left, onChat, onReaction, onWaiting/onJoinRequest, onRecordingStatus, onRoomFull, onProducerActive, onIceStateChange, onClose

Dynacast (0.3.0+) : quand vous êtes seul (aucun abonné à vos pistes), le SDK coupe automatiquement l'upload vidéo à la source et le reprend dès qu'un pair s'abonne — économie d'uplink transparente. État exposé via producerActive / handler onProducerActive(active).

Le SFU parle SDP offer/answer standard sur /ws : aucune notion de rtpCapabilities, createWebRtcTransport ou produce/consume. Le token (via le sous-protocole lunion.token.<JWT>, hors URL) applique les droits canPublish / canSubscribe / roomAdmin… côté SFU.

Chiffrement de bout en bout (optionnel) : E2eeTransformer (AES-GCM par frame, SFU aveugle).

Migration 0.1.x → 0.2.0

| Avant (≤ 0.1.x) | Après (0.2.0) | |---|---| | new SfuClient(handlers, url) | new LunionMeetClient({ url }, handlers) | | connect({ room, name, token }) | connect(room, name, cid?, token?) | | loadDevice(welcome.rtpCapabilities) | (supprimé — RTCPeerConnection standard) | | createSendTransport() / createRecvTransport() | (supprimé) | | produce(track, "camera") | publishCamera() / publishMic() | | onNewProducersubscribe(id) | onTrack(track, streams, …) (abonnement auto) |

⚠️ Un client 0.1.x n'est plus compatible avec le SFU actuel : mettez à jour vers 0.2.0 (déployez le SFU à jour avant les clients).
