Usage

Connect to a Session

import { createSession } from "@8xff/atm0s-media-js";

const url = "<YOUR SERVER URL>";
const token = "<YOUR SERVER TOKEN IF NEEDED>";

// This can be any MediaStream
const stream = await navigator.mediaDevices.getUserMedia({
  audio: true,
  video: true,
});

const session = createSession(url, {
  roomId: "Echo Room",
  peerId: "echo-client",
  token,
  // You can optionally initialize the session with senders and receivers so we won't have to keep
  // updating SDP every time we create a new senders and receivers
  senders: [
    { stream: stream, name: "audio_main", kind: "audio" },
    {
      stream: stream,
      name: "video_main",
      kind: "video",
      // Optionally, you can add simulcast
      simulcast: true,
    },
  ],
  receivers: {
    audio: 1,
    video: 1,
  },
});

// This will connect to the server and send the initialized MediaStream from above 
session.connect();

Consume the stream

By issued stream name

const consumer = session.createConsumerPair(peerId, "audio_main", "video_main");

Or listen to stream events:

// Note: In this specific case, we only have our own stream, so only `mystream_added` is triggered.
// In the case of listening for an external stream, use `stream_added` instead
session.on("mystream_added", (stream) => {
  // The audio stream and video stream added events will be triggered separately

  if (stream.kind === "video") {
    const consumer = session.createConsumer(stream);
    const stream = consumer.view();
    // Do something with stream ...
  }

  if (stream.kind === "audio") {
    const consumer = session.createConsumer(stream);
    const stream = consumer.view();
    // Do something with stream ...
  }
});
