Getting Started

Start your first conversation

CometChat UI Kit for React Native is a collection of prebuilt UI components designed to simplify the development of an in-app chat with all the essential messaging features. Our UI Kit offers light and dark themes, various fonts, colors, and additional customization options.

CometChat UI Kit supports both one-to-one and group conversations. Follow the guide below to initiate conversations from scratch using CometChat React Native UI Kit.

Prerequisites

Before installing UI Kit for React Native, you need to create a CometChat application on the CometChat Dashboard, which comprises everything required in a chat service including users, groups, calls & messages. You will need the App ID , AuthKey, Region of your CometChat application when initialising the SDK.

i. Register on CometChat

  • To install UI Kit for React Native, you need to first register on CometChat Dashboard. Click here to sign up.

ii. Get Your Application Keys

  • Create a new app
  • Head over to the QuickStart or API & Auth Keys section and note the App ID, Auth Key, and Region.
Note

Each CometChat application can be integrated with a single client app. Within the same application, users can communicate with each other across all platforms, whether they are on mobile devices or on the web.

iii. IDE Setup

The minimum requirements for UI Kit for React Native are:

  • Node 14 or later
  • JDK 11
  • Android Studio
  • Xcode
  • iOS 12.0 and later
info
  1. Go to finder -> Applications -> Xcode -> Get Info
  2. Click on Open using Rosetta

Getting Started

You can start building a modern messaging experience in your app by installing the new UI Kit. This developer kit is an add-on feature to CometChat React Native SDK.


Step 1

Create a project

To get started, open terminal and create a new project using below command.

npx react-native init ChatingApp

Step 2

Add Dependency

You can install UI Kit for React Native through using below command.

npm i @cometchat/chat-uikit-react-native

Other Dependencies

npm i @cometchat/chat-sdk-react-native
npm i @react-native-async-storage/async-storage@1.17.10
npm i @react-native-clipboard/clipboard@1.13.2

Add Permissions for android

Open AndroidManifest.xml file from android/app/src/main location and add below permissions

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.INTERNET" />
info

Please make sure Android SDK path is set in the ANDROID_HOME environment variable or in local.properties via the field sdk.dir.

Install @cometchat/calls-sdk-react-native Package (Optional)

If you want calling functionality inside your application then you need to install calling SDK additionally inside your project.

Warning

react native ui kits supports calling SDK V3 or higher

  1. You can install @cometchat/calls-sdk-react-native Calling SDK for React Native using below command.

     npm i @cometchat/calls-sdk-react-native
  2. Install dependancies required for call SDK to work

    // Dependencies required for calls sdk.
    {
    "@cometchat/chat-sdk-react-native": "^4.0.5",
    "@react-native-async-storage/async-storage": "^1.17.5",
    "@react-native-community/netinfo": "7.1.7", // for react-native 0.63 & above.
    "@react-native-community/netinfo": "6.1.0", // for react-native below 0.63
    "react-native-background-timer": "2.4.1",
    "react-native-callstats": "3.73.7",
    "react-native-webrtc": "1.106.1"
    }
  3. Add permissions

    Android:

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    IOS:

    <key>NSCameraUsageDescription</key>
    <string>This is for Camera permission</string>
    <key>NSMicrophoneUsageDescription</key>
    <string>This is for Mic permission</string>

Step 3

Initialise CometChatUIKit

To integrate and run CometChat UI Kit in your app, you need to initialize it beforehand.

The Init method initializes the settings required for CometChat. Please ensure to call this method before invoking any other methods from CometChat UI Kit or CometChat SDK.

info

The Auth Key is an optional property of the UIKitSettings Class. It is intended for use primarily during proof-of-concept (POC) development or in the early stages of application development. You can use the Auth Token method to log in securely.

import React, {useEffect} from 'react'
import { Platform, PermissionsAndroid } from 'react-native'
import { CometChatUIKit, UIKitSettings } from '@cometchat/chat-uikit-react-native'
import { CometChat } from '@cometchat/chat-sdk-react-native'

// add below code in App.js or App.tsx
const getPermissions = () => {
if (Platform.OS == "android") {
PermissionsAndroid.requestMultiple([
PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE,
PermissionsAndroid.PERMISSIONS.CAMERA,
PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
]);
}
}

useEffect(() => {
getPermissions();
let uikitSettings : UIKitSettings= {
appId: <!--Your appId goes here -->,
authKey: <!-- your app authKey goes here -->,
region: <!-- App region goes here -->,
subscriptionType: CometChat.AppSettings.SUBSCRIPTION_TYPE_ALL_USERS,
};

CometChatUIKit.init(uikitSettings)
.then(() => {
console.log("CometChatUiKit successfully initialized")
})
.catch((error) => {
console.log("Initialization failed with exception:", error)
})
},[]);
Step 4

Login User

For login, you require a UID. You can create your own users on the CometChat Dashboard or via API. We have pre-generated test users: cometchat-uid-1, cometchat-uid-2, cometchat-uid-3, cometchat-uid-4, cometchat-uid-5.

The Login method returns the User object containing all the information of the logged-in user.

info

This straightforward authentication method is ideal for proof-of-concept (POC) development or during the early stages of application development. For production environments, however, we strongly recommend using an Auth Token instead of an Auth Key to ensure enhanced security.

let uid = <# Enter User's UID Here #>

CometChatUIKit.login({uid: uid})
.then(user => {
console.log("User logged in successfully \(user.getName())")
})
.catch((error) => {
console.log("Login failed with exception:", error)
})
Note
  • 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.

Step 5

Render Conversation With Message

ConversationsWithMessages is a wrapper component that offers functionality to render both the Conversations and Messages components. It also enables opening the Messages by tapping on any conversation rendered in the list of conversations.

Image
<CometChatConversationsWithMessages />
info

It will automatically fetch the conversation data upon loading the list. If the conversation list is empty, you can start a new conversation.

Warning

Make sure you add a Privacy Manifest File to your app before going live
