Let's begin with the prebuilt sdk setup. Read all the steps carefully before installing one in your application.

Video Calling Embed in Any Website and App

1: First of all, Register yourself to app.videosdk.live

2: Generate an API key and Secret

Implementation

3: Import the script in your html page

 <script src="https://sdk.videosdk.live/rtc-js-prebuilt/0.3.21/rtc-js-prebuilt.js"></script>

Note: You can also use official Npm package: rtc-js-prebuilt

4: Embed Video Calling javascript prebuilt code to your HTML page

<script>
  var script = document.createElement("script");
  script.type = "text/javascript";

  script.addEventListener("load", function (event) {
    const meeting = new VideoSDKMeeting();

    const config = {
      name: "John Doe",
      apiKey: "<API KEY>", // generated in Setup
      meetingId: "milkyway", // enter your meeting id

      containerId: null,
      redirectOnLeave: "https://www.videosdk.live/",

      micEnabled: true,
      webcamEnabled: true,
      participantCanToggleSelfWebcam: true,
      participantCanToggleSelfMic: true,

      chatEnabled: true,
      screenShareEnabled: true,
      pollEnabled: true,
      whiteBoardEnabled: true,
      raiseHandEnabled: true,

      recordingEnabled: true,
      recordingWebhookUrl: "https://www.videosdk.live/callback",
      participantCanToggleRecording: true,

      brandingEnabled: true,
      brandLogoURL: "https://picsum.photos/200",
      brandName: "Awesome startup",
      poweredBy: true,

      participantCanLeave: true, // if false, leave button won't be visible

      // Live stream meeting to youtube
      livestream: {
        autoStart: true,
        outputs: [
          // {
          //   url: "rtmp://x.rtmp.youtube.com/live2",
          //   streamKey: "<STREAM KEY FROM YOUTUBE>",
          // },
        ],
      },

      whiteboardEnabled: true,

      permissions: {
        askToJoin: false, // Ask joined participants for entry in meeting
        toggleParticipantMic: true, // Can toggle other participant's mic
        toggleParticipantWebcam: true, // Can toggle other participant's webcam
        drawOnWhiteboard: true,
        toggleWhiteboard: true,

      },

      joinScreen: {
        visible: true, // Show the join screen ?
        title: "Daily scrum", // Meeting title
        meetingUrl: window.location.href, // Meeting joining url
      },
    };

    meeting.init(config);
  });

  script.src =
    "https://sdk.videosdk.live/rtc-js-prebuilt/0.1.21/rtc-js-prebuilt.js";
  document.getElementsByTagName("head")[0].appendChild(script);
</script>

5: Insert API key in your code to run it

apiKey: "<API-KEY>"

Note: To restrict use of your API key on other domains, you can add domain URL which will block use of your API key in other domains.

Run the demo

To run the demo, you have to use any local server. Best could be Xampp or IIS as per your environment. We are going to use live-server package to run simple http server.

$ npm install -g live-server
$ live-server --port=8000

and open http://localhost:8000 in your web browser.

Record the meeting

To record the meeting, You have to first enable recording flag in the configuration.

recordingEnabled: set true or false to enable and disable online recordings
recordingWebhookUrl: Callback url, generally helps to store recording details on your database.

 recordingEnabled: true,
 recordingWebhookUrl: "https://www.videosdk.live/callback",

After enabling recording option, you'll be able to see recording button on the screen. Click on it to start and stop recording

Enable WhiteBoard

To enable whiteboard, you have to configure whiteboard flag and permissions.

whiteboardEnabled: if true, it will enable whiteboard
permission: you can also set permission of who can drawOnWhiteboard and toggleWhiteboard by using boolean value

whiteboardEnabled: true,
  permissions: {
    drawOnWhiteboard: true,
    toggleWhiteboard: true,
  },

Go live on social media

To enable live streaming, you have to configure list of stream key and URL. We only support RTMP protocol enabled broadcasting.

autoStart: If true, it will trigger re-streaming automatically when meeting will start.

livestream: {
    autoStart: true,
    outputs: [
        // {
        //   url: "rtmp://x.rtmp.youtube.com/live2",
        //   streamKey: "<STREAM KEY FROM YOUTUBE>",
        // },
    ],
}

Pin Screen

To enable pin screen, you have to configure pin property. It includes two major properties:

allowed: If it is true then that participant can pin or unpin other participants in the meeting, by default it is set to false.
layout: It should be a any of GRID or SPOTLIGHT or SIDEBAR, by default it is set to GRID.

Better understanding of Layouts

GRID

GRID: This layout is default layout if no participants are pinned, it will look same as a normal meeting grid layout, when any participant is pinned that participant will be moved on top of the main screen grid above all non pinned participants

SIDEBAR

SIDEBAR: This layout will have one main screen view and other sidebar grid layout. Only pinned participant will be visible in this layout, all unpinned participants will not be visible in this layout. If more than one participant is pinned then the first participant who was pinned will appear in main screen layout and all other remaining pinned participants will be visible in sidebar.

SPOTLIGHT

SPOTLIGHT: This layout will only contain main screen layout, multiple pinned participants will be visible in main screen view. Same as SIDEBAR layout only pinned participants will be visible in main screen.

pin: {
 allowed: true,
 layout: "SPOTLIGHT",
}

Conclusion

In this article, I have explained Video Chat in JavaScript. You can modify couple of parameters in code according to your need. This was the small introduction to Video SDK Prebuilt SDK.
