About chat-uikit-react-native

chat-uikit-react-native is a React Native UI component library based on Tencent Cloud Chat SDK. It provides universally used UI components that include ConversationList, Chat, and Group components. Leveraging these meticulously crafted UI components, you can quickly construct an elegant, reliable, and scalable Chat application.

In respect for the copyright of the emoji design, the Chat Demo/TUIKit project does not include the cutouts of large emoji elements. Please replace them with your own designed or copyrighted emoji packs before the official launch for commercial use. The default small yellow face emoji pack is copyrighted by Tencent Cloud and can be authorized for a fee. If you wish to obtain authorization, please submit a ticket to contact us.

Before getting started

This section shows the prerequisites you need to check to use @tencentcloud/chat-uikit-react-native.

Requirements

• React Native 0.75.0
• Nodejs 18 or newer
• JDK 17 or newer
• Xcode version 14.0 or newer
• Android Studio

More details, please see https://reactnative.dev/docs/environment-setup

Getting started

This section gives you information you need to get started with chat-uikit-react-native.

Create a project

You can get started by creating a project with react-native 0.75.0. (highly recommended to use typescript)

npx @react-native-community/cli@latest init ChatApp --version 0.75.0

Navigate to the app directory

cd ChatApp

Install chat-uikit-react-native

chat-uikit-react-native can be installed through either yarn or npm

use npm

npm install @tencentcloud/chat-uikit-react-native

use yarn

yarn add @tencentcloud/chat-uikit-react-native

Install media library Dependencies

use npm

npm install react-native-image-picker react-native-document-picker react-native-video

use yarn

yarn add react-native-image-picker react-native-document-picker react-native-video

Getting permissions

Client apps must acquire permission from users to get access to their media library and save files to their mobile storage. Once the permission is granted, users can send images and videos to other users and save media files.

Android

Add the following permissions to your android/app/src/main/AndroidManifest.xml file.

  <uses-permission android:name="android.permission.READ_MEDIA_IMAGES" />
  <uses-permission android:name="android.permission.READ_MEDIA_AUDIO" />
  <uses-permission android:name="android.permission.READ_MEDIA_VIDEO" />
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

iOS

Add the following permission usage descriptions to your info.plist file.

  <key>NSCameraUsageDescription</key>
  <string> we would like to use your camera</string>
  <key>NSPhotoLibraryUsageDescription</key>
  <string> we would like to use your photo library</string>
  <key>NSMicrophoneUsageDescription</key>
  <string>we would like to use your microphone</string>

Login chat-uikit-react-native

Now you can use TUILogin login to chat-uikit-react-native.

The options parameter is of the Object type. It contains the following attribute values: | Name | Type | Description | | --- | --- | --- | | SDKAppID | number | Required, SDKAppID of the chat app | | userID | string | Required, user ID| | userSig |string | Required, the password with which the user logs in to the Chat console. It is essentially the ciphertext generated by encrypting information such as the UserID. For the detailed generation method, see Generating UserSig | | useUploadPlugin | boolean | Optional, whether to use the upload plugin, the default is false | | framework | string | undefined | Required, UI framework type, optional values: rn、undefined |

import { TUILogin } from '@tencentcloud/tui-core';
TUILogin.login(options);

Integration with navigation library

Now you can create a screen and integrate it with a navigation library like react-navigation.

Install react-navigation

react-navigation can be installed through either yarn or npm

use npm

npm install @react-navigation/native react-native-screens react-native-safe-area-context @react-navigation/native-stack

use yarn

yarn add @react-navigation/native react-native-screens react-native-safe-area-context @react-navigation/native-stack

The example below shows how to integrate using react-navigation.

Create a fragments and screens

Create a new Screens.tsx in the same directory as App.tsx.

import React from 'react';
import { useNavigation } from '@react-navigation/native';
import { ConversationList, Chat, ChatSetting } from '@tencentcloud/chat-uikit-react-native';

export const ConversationListScreen = () => {
  const navigation = useNavigation<any>();
  const onPressConversation = () => {
    navigation.navigate('Chat');
  };
  return (
    <ConversationList onPressConversation={onPressConversation} />
  );
};

export const ChatScreen = () => {
  const navigation = useNavigation<any>();
  const navigateBack = () => {
    navigation.goBack();
  };
  const navigateToChatSetting = () => {
    navigation.navigate('ChatSetting');
  };
  return (
    <Chat
      navigateBack={navigateBack}
      navigateToChatSetting={navigateToChatSetting}
    />
  );
};

export const ChatSettingScreen = () => {
  const navigation = useNavigation<any>();
  // Navigate to Chat when you click header back button.
  const navigateBack = () => {
    navigation.goBack();
  };
  // Navigate to Chat when you click the send message button.
  const navigateToChat = () => {
    navigation.goBack();
  };
  // Navigate to ConversationList when you disband group or leave group.
  const navigateToConversationList = () => {
    navigation.navigate('ConversationList');
  };
  return (
    <ChatSetting
      navigateBack={navigateBack}
      navigateToChat={navigateToChat}
      navigateToConversationList={navigateToConversationList}
    />
  );
};

Register screens to navigator

import React from 'react';
import {
  View,
  TouchableOpacity,
  Text,
  Image,
  StyleSheet,
} from 'react-native';
import { NavigationContainer, useNavigation } from '@react-navigation/native';

import { UIKitProvider } from '@tencentcloud/chat-uikit-react-native';
import resources from '@tencentcloud/chat-uikit-react-native/i18n';
import { TUITranslateService } from '@tencentcloud/chat-uikit-engine';
import { TUILogin } from '@tencentcloud/tui-core';
import { ConversationListScreen, ChatScreen, ChatSettingScreen } from './Screens';

const LoginScreen = () => {
  const navigation = useNavigation<any>();
  // Init localization
  TUITranslateService.provideLanguages(resources);
  TUITranslateService.useI18n('en-US');
  // Login
  const Login = () => {
    TUILogin.login({
      SDKAppID: 0,
      userID: '',
      userSig: '',
      useUploadPlugin: true,
      framework: 'rn',
    }).then(() => {
      navigation.navigate('ConversationList');
    });
  }

  return (
    <View style={styles.container}>
      <Image
        style={styles.logo}
        source={{uri:'https://web.sdk.qcloud.com/im/assets/images/tencent_rtc_logo.png'}}
      />
      <TouchableOpacity style={styles.buttonContainer} onPress={Login}>
        <Text style={styles.buttonText}>Log in</Text>
      </TouchableOpacity>
    </View>
  );
};

const Navigation = () => {
  const Stack = createNativeStackNavigator();
  return (
    <NavigationContainer>
      <Stack.Navigator
        screenOptions={{ headerShown: false }}
        initialRouteName="Login">
        <Stack.Screen
          name="Login"
          component={LoginScreen} />

          component={ChatScreen} />
        <Stack.Screen
          name="ChatSetting"
          component={ChatSettingScreen}/>
      </Stack.Navigator>
    </NavigationContainer>
  );
};

const App = () => {
  return (
    <UIKitProvider>
      <Navigation />
    </UIKitProvider>
  );
};

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#FFFFFF',
  },
  logo: {
    width: 232,
