Configure CometChat inside your React Native app

  • Initialize CometChat 🌟
The init() method initializes the settings required for CometChat. We suggest calling the init() method on app startup, preferably in the created() method of the Application class. 
import {CometChat} from '@cometchat-pro/react-native-chat';

const appID = 'APP_ID';
const region = 'REGION';
const appSetting = new CometChat.AppSettingsBuilder()
  .subscribePresenceForAllUsers()
  .setRegion(region)
  .build();
CometChat.init(appID, appSetting).then(
  () => {
    console.log('Initialization completed successfully');
    // You can now call login function.
  },
  (error) => {
    console.log('Initialization failed with error:', error);
    // Check the reason for error and take appropriate action.
  },
);
Replace APP_ID and REGION with your CometChat App ID and Region in the above code
  • Login your user 👤
This method takes UID and Auth Key as input parameters and returns the User object containing all the information of the logged-in user. 
import {CometChat} from '@cometchat-pro/react-native-chat';

const authKey = 'AUTH_KEY';
const uid = 'cometchat-uid-1';

CometChat.login(uid, authKey).then(
  (user) => {
    console.log('Login Successful:', { user });
  },
  (error) => {
    console.log('Login failed with exception:', { error });
  },
);
Replace AUTH_KEY with your CometChat Auth Key in the above code.
We have set up 5 users for testing having UIDs: cometchat-uid-1, cometchat-uid-2, cometchat-uid-3, cometchat-uid-4, and cometchat-uid-5.We have used uid cometchat-uid-1 as an example here. You can create a User from CometChat Dashboard as well.

import React from 'react';
import {View} from 'react-native';
import {CometChatUI} from '../cometchat-pro-react-native-ui-kit';
