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

Building a video call app with React Native is considered easier for several reasons, making it a popular choice among developers looking to deploy apps across multiple platforms efficiently. Here are some of the key factors that contribute to the ease of developing video call apps with React Native:

  1. Cross-Platform Development: React Native allows for a single codebase to be used for both iOS and Android platforms, significantly reducing development time and effort. This means developers can build a video call app once and deploy it across multiple platforms without needing to rewrite the app in different programming languages for each platform.
  2. Rich Ecosystem and Libraries: React Native has a robust ecosystem and a wide range of libraries, including many for video calling features such as WebRTC for real-time communication. These libraries are well-documented and supported, making it easier to implement complex functionalities like video calling.
  3. Component-Based Architecture: React Native uses a component-based architecture, which allows developers to build apps with reusable components. This not only speeds up the development process but also improves the maintainability and scalability of the app.
  4. Hot Reloading: The hot reloading feature in React Native enhances developer productivity by allowing them to see the results of the latest changes in real-time without restarting the app. This is particularly useful during the development of interactive features like video calls, as it speeds up the iteration process.
  5. Strong Community Support: React Native has a large and active developer community, providing a wealth of resources, tools, and support. Developers can easily find solutions to common problems, get advice from experienced peers, and stay updated with the latest best practices and innovations.
  6. Integration with Native Modules: For features that require direct access to the device’s hardware (like camera and microphone access for video calls), React Native allows developers to integrate native modules written in Swift, Objective-C, or Java. This ensures that apps can leverage platform-specific functionalities and optimizations for high-quality video calls.

These advantages make React Native an attractive framework for developers looking to build efficient, cross-platform video call apps with less complexity and in a shorter timeframe.

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 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 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
