Usage Example

import { Device } from "mediasoup-client";
import mySignaling from "./my-signaling"; // Our own signaling stuff.

// Create a device (use browser auto-detection).
const device = new Device();

// Communicate with our server app to retrieve router RTP capabilities.
const routerRtpCapabilities = await mySignaling.request(
  "getRouterCapabilities"
);

// Load the device with the router RTP capabilities.
await device.load({ routerRtpCapabilities });

// Check whether we can produce video to the router.
if (!device.canProduce("video")) {
  console.warn("cannot produce video");

  // Abort next steps.
}

// Create a transport in the server for sending our media through it.
const { id, iceParameters, iceCandidates, dtlsParameters, sctpParameters } =
  await mySignaling.request("createTransport", {
    sctpCapabilities: device.sctpCapabilities,
  });

// Create the local representation of our server-side transport.
const sendTransport = device.createSendTransport({
  id,
  iceParameters,
  iceCandidates,
  dtlsParameters,
  sctpParameters,
});

// Set transport "connect" event handler.
sendTransport.on("connect", async ({ dtlsParameters }, callback, errback) => {
  // Here we must communicate our local parameters to our remote transport.
  try {
    await mySignaling.request("transport-connect", {
      transportId: sendTransport.id,
      dtlsParameters,
    });

    // Done in the server, tell our transport.
    callback();
  } catch (error) {
    // Something was wrong in server side.
    errback(error);
  }
});

// Set transport "produce" event handler.
sendTransport.on(
  "produce",
  async ({ kind, rtpParameters, appData }, callback, errback) => {
    // Here we must communicate our local parameters to our remote transport.
    try {
      const { id } = await mySignaling.request("produce", {
        transportId: sendTransport.id,
        kind,
        rtpParameters,
        appData,
      });

      // Done in the server, pass the response to our transport.
      callback({ id });
    } catch (error) {
      // Something was wrong in server side.
      errback(error);
    }
  }
);

// Set transport "producedata" event handler.
sendTransport.on(
  "producedata",
  async (
    { sctpStreamParameters, label, protocol, appData },
    callback,
    errback
  ) => {
    // Here we must communicate our local parameters to our remote transport.
    try {
      const { id } = await mySignaling.request("produceData", {
        transportId: sendTransport.id,
        sctpStreamParameters,
        label,
        protocol,
        appData,
      });

      // Done in the server, pass the response to our transport.
      callback({ id });
    } catch (error) {
      // Something was wrong in server side.
      errback(error);
    }
  }
);

// Produce our webcam video.
const stream = await navigator.mediaDevices.getUserMedia({ video: true });
const webcamTrack = stream.getVideoTracks()[0];
const webcamProducer = await sendTransport.produce({ track: webcamTrack });

// Produce data (DataChannel).
const dataProducer = await sendTransport.produceData({
  ordered: true,
  label: "foo",
});
