In this guide, we’ll walk you through the process of building a React Native video call app from start to finish with ZEGOCLOUD. Get ready to learn how to create a top-notch video chat app!

Why is Building a Video Call App with React Native Easier?

Building a video call app with React Native is considered easier due to its cross-platform nature, allowing developers to write code once and deploy it on both iOS and Android platforms. This significantly reduces development time and effort, as there’s no need to maintain separate codebases for each platform. React Native’s extensive library of pre-built components, including those for video calling features, further streamlines the development process. Developers can easily integrate advanced functionalities like real-time video streaming, without delving into the complexities of native code for each platform.

Moreover, React Native benefits from a large and active community, providing access to a wealth of resources, tools, and third-party plugins. This community support means developers can find solutions to common problems quickly and leverage existing libraries to add features like video call recording or screen sharing with minimal effort. The framework’s hot-reload feature also allows for instant feedback on code changes, making the development and debugging process more efficient. All these factors combined make React Native an appealing choice for building sophisticated video call apps with ease.

  7. Payment Gateway Integration: Essential for e-commerce or service-based apps, allowing secure and convenient in-app purchases or transactions.
  8. Dark Mode: A popular feature that offers a dark color scheme to reduce eye strain in low-light conditions and save battery life on OLED/AMOLED screens.
  9. Biometric Authentication: Enhances security by allowing users to log in using fingerprint scanning or facial recognition, offering a seamless and secure experience.
  10. Analytics and Feedback System: Collects data on how users interact with your app and gathers direct feedback, crucial for ongoing improvement and personalization.

Incorporating these features into your React Native app can create a more engaging, convenient, and valuable experience for your users, setting your app apart in the competitive app market.

Why Do You Need ZEGOCLOUD SDK to Build a React Native Video Chat App?

ZEGOCLOUD is a video communication platform that provides a fully customized video chat API for React Native developers to integrate video call functionality into their React Native applications. Developers can easily build cross-platform video communication apps for iOS and Android. It provides pre-built UIKits to its users for effective building, which allows developers to make their app development easier and faster within a few minutes.

As you have assessed the need to create a video call app for your system, taking ZEGOCLOUD’s help is effective. Using React native UIKits for video communication would simplify the complete design. Rather than hiring individuals, this turns out to be the best way to execute the process in no time.

When Do You Need UIKits for Video Chat with React Native

The benefits of using UIKits cannot be overstated. There is definitely no doubt that it is the best video call SDK out there. It is mighty for many reasons.

1. Build apps faster and easier.

This is one of the primary reasons for the React Native development of UIKits. It lets you get your video call apps up and running with a few lines of code. You don’t have to worry about the core implementation, as everything is taken care of behind the scenes. UIKits also supports many frameworks, so you don’t have to learn any frameworks to use them. For instance, we will implement a video call feature using React Native video SDK. If you are unfamiliar with React Native, you can use other development tools such as Flutter or Web.

2. Customize the UI and features as needed.

UIKits is highly customizable, unlike other UIKit tools out there. You can easily customize the look and improve the features of your video call app as per your needs by simply tweaking the code. There’s no doubt that the UIKits SDK has all the functionality you could ever need in a call app.

Apart from the two features mentioned above, below are some powerful features that UIKits SDK offers out of the box:

  • Ready-to-use 1-on-1/group calls
  • Customizable UI styles
  • Real-time sound waves display
  • Device management
  • Switch views during a 1-on-1 call.
  • Extendable menu bar
  • Participant list

As shown in the figure, React Native UIKit SDK from ZEGOCLOUD is responsible for processing audio and video calls and the logic related to text chat. Include:

  • UI and interaction of the calling module
  • call status management
  • Audio and video data transmission

You only need to implement business-related logic. For example:

  • User login registration
  • Friends List Management
  • Call billing recharge

  • A ZEGOCLOUD developer account–Sign up
  • React Native 0.60.0 or later
  • Basic understanding of React Native development

Steps to Implement Video Call for React Native App

1. Create Project

First, You need to run the following code to create a new project.

npx react-native init call
create video call project

2. Add React Native UIKit SDK dependencies

Next, you need to open the package.json file in the root directory and add the React Native UIKit SDK dependencies.

"@react-navigation/native": "^6.0.13",
"@react-navigation/native-stack": "^6.9.1",
"@zegocloud/zego-uikit-prebuilt-call-rn": "^1.2.1",
"@zegocloud/zego-uikit-rn": "^1.2.0",
"react-delegate-component": "^1.0.0",
"react-native-gesture-handler": "^2.8.0",
"react-native-safe-area-context": "^4.4.1",
"react-native-screens": "^3.18.2",
"react-navigation": "^4.4.4",
"zego-express-engine-reactnative": "^0.21.0"
add sdk dependencies

3. Add a call button

import { NavigationContainer, useNavigation} from '@react-navigation/native';
import React from "react";
import { Button, View} from 'react-native'
import { createNativeStackNavigator } from '@react-navigation/native-stack';

const Stack = createNativeStackNavigator();
export default function App() {
  return (
      <Stack.Navigator initialRouteName="HomePage">
        <Stack.Screen name="HomePage" component={HomePage} />

function HomePage(props) {
    const navigation = useNavigation();
    return (
        <View style={{flex: 1,alignItems: 'center',justifyContent: 'space-around'}}>
            <Button title="Call" onPress={() => { navigation.navigate('CallPage') }} />
react native uikit

4. Add Video Call page

Use ZegoUIKitPrebuiltCall to easily build a Call page

import ZegoUIKitPrebuiltCall, {GROUP_VOICE_CALL_CONFIG} from '@zegocloud/zego-uikit-prebuilt-call-rn';
function CallPage(props) {
  randomUserID = String(Math.floor(Math.random() * 100000))
  return (
      <View style={{flex: 1}}>
            appSign='Your App Sign'

              onHangUp: () => {props.navigation.navigate('HomePage')},

Now, you can make a new call by navigating to this CallPage.

5. Add Device permission

  1. Open the my_project/android/app/src/main/AndroidManifest.xml file and add the permission:
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WAKE_LOCK" />
  1. Open the my_project/android/app/ file and add the following:
-keep class **.zego.**  { *; }
configure project

Open the my_project/ios/my_project/Info.plist file and add the following:

<string>We need to use the camera</string>
<string>We need to use the microphone</string>

Run a demo
