How to Build A React Native Video Calling App?

“If you are someone who wants to explore react native video chat app at the most technical level, or can say in-depth.. I have something amazing for you!”

Where modern technology is all about building connections around the world. This COVID-19 pandemic has raised their hands and involved all kinds of industries into it’s considered boundaries, where they have to rely over the modern technology to stay connected.

Yes! Today the video calling has been proven to be the best in all, whether it’s about meeting with productivity tips or collaboration across the possibilities, it has been encountered as the best in practice ever.

Although, I have crafted content on many SDKs with their pre-built communication features before. But, the main intention of this post is to provide you with the best when it comes to money and time, Of course when you are planning to build your secure video conferencing app especially using the powerful React Native SDKs technology. So, let’s dive and know more! 

Build a React Native Video Chat App with MirrorFly SDK

The easiest and fastest way to add video calling functionality to your platform is by integrating a video calling SDK, in just 20 mins. 

Note:
Don’t have an app already, you can get started with our sample app here.

Basic Requirements

Use the MirrorFly React Native SDK and install the below mentioned dependencies to start developing your video call app. 

• Node – 14.20.0
• npm – 6.14.10
• react-native – 0.69.12

Getting Started

To start the development, you will first need a license key to authenticate the SDK on your app. To do this, follow these steps:

To get the License Key,

Step 1: Contact our experts 

Step 2: Set up your MirrorFly account

Step 3: Login to your Account

Step 4: Go to the App info section in your account 

Step 5: Get the license key

Use NPM package for the Installation

Step 1: Install the React Native SDK into your app using NPM installation.

npm i mirrorfly-reactnative-sdk

Step 2: Choose the destination in your project and import the SDK. 

import { SDK } from "mirrorfly-reactnative-sdk";

Add NPM Package Dependencies

Follow the instructions here and add the chat-related dependencies.

{
   // Add chat related dependencies. And then add the below calls related dependencies
   "react-native-webrtc": "118.0.2", // must use version "118.0.2"
   "react-native-background-timer": "2.*.*"
  }

Initialize Calls SDK

To start with the SDK initialization, you will need specific data. So that whenever there are changes in the connection status of the client app, these data will be helpful for the SDK to respond accordingly. 

Now, in the licensekey param, use the license key you got from your account. Pass the dats through the SDK using the below method:

const incomingCallListener = (res) => {};
const callStatusListener = (res) => {};
const userTrackListener = (res) => {};
const muteStatusListener = (res) => {};
const missedCallListener = (res) => {};
const mediaErrorListener = (res) => {};
const callSpeakingListener = (res) => {};
const callUsersUpdateListener = (res) => {};
const helper = {}

const initializeObj = {
  apiBaseUrl: `API_URL`,
  licenseKey: `LICENSE_KEY`,
  isTrialLicenseKey: `TRIAL_MODE`,
  callbackListeners: {
    connectionListener,
    incomingCallListener,
    callStatusListener,
    userTrackListener,
    muteStatusListener,
    missedCallListener,
    mediaErrorListener,
    callSpeakingListener,
    callUsersUpdateListener,
    helper
  },
};
await SDK.initializeSDK(initializeObj);

Sandbox Details

From the Overview section of your account get the apiUrl and licenseKey details.

function connectionListener(response) {
  if (response.status === "CONNECTED") {
    console.log("Connection Established");
  } else if (response.status === "DISCONNECTED") {
    console.log("Disconnected");
  }
}

const initializeObj = {
  apiBaseUrl: "https://api-preprod-sandbox.mirrorfly.com/api/v1",
  licenseKey: "XXXXXXXXXXXXXXXXX",
  isTrialLicenseKey: true,
  callbackListeners: {
    connectionListener
  },
};
await SDK.initializeSDK(initializeObj);

Example Response

{
  "statusCode": 200,
  "message": "Success"
}

Register User

Step 1: To register a new user, use the below given method. 

Step 2: When you register, you will get a username and password. You can make use of these credentials to make a connection with the chat server using the connect method.

await SDK.register(`USER_IDENTIFIER`, `ANDROID_FCM_TOKEN`, `IOS_VOIP_TOKEN`, `IS_PRODUCTION`);

Sample Code for Register User

import messaging from '@react-native-firebase/messaging';
import RNVoipPushNotification from 'react-native-voip-push-notification';


RNVoipPushNotification.addEventListener('register', async voipToken => {
   const fcmToken = await messaging().getToken();
   SDK.register(userIdentifier, fcmToken, voipToken, process.env?.NODE_ENV === "production");
});

// =====  register for VOIP =====
RNVoipPushNotification.registerVoipToken();

Sample Response:

{
  statusCode: 200,
  message: "Success",
  data: {
    username: "123456789",
    password: "987654321"
  }
}

Connect to MirrorFly Server

Step 1: Use the credentials you obtained from the above step and start connecting with the MirrorFly server. 

Step 2: If your connection is successful, you will give an approval messages as ‘statusCode of 200’. Otherwise, willl get an execution error.Step 3: This way, you can trace the connection status of your React Native app using the connectionListener callback function.

await SDK.connect(`USERNAME`, `PASSWORD`);

Sample Response:

{
  message: "Login Success",
  statusCode: 200
}

Actions Generated During A Call Session

“React Native with WebRTC with tutorial can build entire call session”

Whenever the user is planning to make a call, there are only a few possible outcomes like making a call, attending a call, then ending up a call or hanging up. Let’s study this in technical terms,

1) Call Accepted 

This is the scenario where the call is received on the application and it’s been accepted as incoming call requests. Now, in technical terms this is possible with the specification of the session ID, here the user needs to accept this session ID in terms to accept the call. 

2) Call Rejected 

This will be the case when the incoming call has not been answered and cutted off. Such cases will be notified to the app by rejecting the session ID as the user wants to reject.

3) Call Hang Up 

This indicates the end of a call. Here, the app will be notified of the instruction by ending the session ID.

Final Touch

“The end executes the react native video chat app with endless connections”

Once all the above steps have been performed as per the instructions, the user will be able to have a fully functional React Native video chat app. However, CONTUS MirrorFly makes the entire process the most simple and easy one with it’s highly interactive SDKs and guided documentations.

Take Away

Well, the above technical stuff is one that takes place at the backend while building a react native video calling app. These are some of a few core coding steps but there are much more to explore. 

If this interests your attention to build your react native chat app, feel free to contact our proficient team of developers for further clarity to proceed

All the Best!
