Video Calling in Javascript Prebuilt SDK provides best video chat experience with just 10 lines of code. It provides inbuilt support for

It supports all the modern frameworks such as plain JavaScript, React JS, Vue JS and Angular JS.

#Step 5: Video Calling in Javascript

##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/0.1.4/rtc-js-prebuilt.js"></script>

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

##4: Add 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>",
          // },
        ],
      },

      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
      },

      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/0.1.5/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

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>",
        // },
    ],
}

Conclusion
