The QuickBlox UIKit for React comprises a collection of pre-assembled UI components that enable effortless creation of an in-app chat equipped with all the necessary messaging functionalities.

Our development kit encompasses light and dark themes, colors, and various other features. These components can be personalized to fashion an engaging messaging interface that reflects your brand’s distinct identity.

The QuickBlox UIKit fully supports both private and group dialogs. To initiate the process of sending a message from the ground up using Java or Kotlin, please refer to the instructions provided in the guide below.

​

Requirements

The minimum requirements for QuickBlox UIKit for React are:

• JS QuickBlox SDK v2.15.5
• React v.18.0
• TypeScript v.4.9.3

​

Before you begin

Register a new account following this link. Type in your email and password to sign in. You can also sign in with your Google or GitHub accounts. Create the app clicking New app button. Configure the app. Type in the information about your organization into corresponding fields and click Add button. Go to Dashboard => YOUR_APP => Overview section and copy your Application ID, Authorization Key, Authorization Secret, and Account Key .

​

Helicopter overview

Before you start coding, let’s provide a brief introduction and explain the steps for developers. Firstly, you should install our JS SDK and UIKit. Secondly, you need to create a session, log in using the credentials of an already registered user, and connect to the chat.

​

Install QuickBlox SDK

npm install quickblox

​

Install QuickBlox UIKit

npm install quickblox-react-ui-kit

​

Init QuickBlox SDK

To init QuickBlox SDK you need to pass Application ID, Authorization Key, Authorization Secret, and Account Key to the init() method.

`var APPLICATION_ID = 41;
var AUTH_KEY = "lkjdueksu7392kj";
var AUTH_SECRET = "iiohfdija792hj";
var ACCOUNT_KEY = "sdjfnksnlk2bk1k34kb";
var CONFIG = { debug: true };

QB.init(APPLICATION_ID, AUTH_KEY, AUTH_SECRET, ACCOUNT_KEY, CONFIG);

​

Authentication

Before sending your first message you need to authenticate users in the QuickBlox system. You can read more about different ways of authentication by this link. In our example we show how to authenticate user with login and password.

import * as QB from "quickblox/quickblox";
import { QuickBloxUIKitProvider } from 'quickblox-ui-kit-react';

QB.createSession(function(error, result) {
  var params = { login: "garry", password: "garry5santos" };

  QB.login(params, function(error, result) {
    if(error){
    } else {
      //Connect to chat and navigate User to the UIKit
  });
});

​

Get started

The entire process consists of several steps:

• Creating a React Project with TypeScript
• Adding Dependencies to a React Project
• Adding QBconfig.ts File to Your React Application
• Perhaps updating the project structure according to your needs
• Configure QuickBloxUIKitProvider

​

Step 1. Creating a React Project with TypeScript and Webpack

In this section, we will guide you through creating a new React project using TypeScript and Webpack without using create-react-app. This manual setup gives you complete control over the build process, which is useful when integrating advanced SDKs and UIKits.

Initializing the Project

1. Open your terminal and create a new project directory:

mkdir react-chat-ui-kit-init-sample
cd react-chat-ui-kit-init-sample
npm init -y

Installing Dependencies

Install the required libraries and tools:

# Application dependencies
npm install react react-dom

# TypeScript and types
npm install --save-dev typescript @types/react @types/react-dom @types/node

# Webpack and its core plugins
npm install --save-dev webpack webpack-cli webpack-dev-server html-webpack-plugin copy-webpack-plugin

# Loaders for styles and scripts
npm install --save-dev ts-loader style-loader css-loader sass-loader sass

# Babel support
npm install --save-dev babel-loader @babel/core @babel/preset-env @babel/preset-react @babel/preset-typescript

# SVG loader
npm install --save-dev @svgr/webpack

Creating Configuration Files

Create a tsconfig.json in the root folder:

{
  "compilerOptions": {
    "target": "ESNext",
    "lib": ["DOM", "DOM.Iterable", "ESNext"],
    "allowJs": true,
    "skipLibCheck": true,
    "esModuleInterop": true,
    "allowSyntheticDefaultImports": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true,
    "module": "ESNext",
    "moduleResolution": "Node",
    "resolveJsonModule": true,
    "isolatedModules": true,
    "jsx": "react-jsx",
    "noEmit": true
  },
  "include": ["src"]
}

Also create a webpack.config.js file (see example in the QuickBlox repository for a complete working configuration webpack.config.js).

Creating the Project Structure

Manually create the following folder and file structure:

public/
  index.html
src/
  App.tsx
  App.css
  index.tsx
  QBconfig.ts
  logo.svg
webpack.config.js
tsconfig.json
package.json

Example of public/index.html

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <title>React UIKit Example</title>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
  </head>
  <body>
    <div id="root"></div>
  </body>
</html>

Creating the Entry Point

In src/index.tsx, add the following code:

import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import './index.css';

const root = ReactDOM.createRoot(document.getElementById('root') as HTMLElement);
root.render(<App />);

Adding NPM Scripts

In your package.json, update the scripts section to include:

"scripts": {
  "start": "webpack serve --mode development",
  "build": "webpack --mode production"
}

Running the Project

Start the development server:

npm run start

Then open your browser at https://localhost:3000 to view the running application.

You now have a working React + TypeScript + Webpack project ready to integrate the QuickBlox UIKit. Continue to the next section to add the required configuration and SDK logic.

​

Step2. Adding Dependencies to a React Project

To successfully integrate QuickBlox functionality into your React project, you need to add two main dependencies: quickblox and quickblox-react-ui-kit. By following the documentation, you can easily add these packages to your project.

Installing Dependencies

1. Open your command prompt or terminal and navigate to the root folder of your React project.
2. Run the following command to install the quickblox package:

 npm install quickblox --save

3. Then, execute the following command to install the quickblox-react-ui-kit package:

npm install quickblox-react-ui-kit --save

Importing Dependencies in the Project

1. Open the file where you want to use QuickBlox functionality, such as App.tsx
2. Add the following lines at the beginning of the file to import the dependencies:

// @ts-ignore
import * as QB from "quickblox/quickblox";
import 'quickblox-react-ui-kit'

Using QuickBlox in the Project

Now that the dependencies are successfully added to your project, you can utilize QuickBlox functionality within the relevant components and modules of your application. Refer to the QuickBlox and QuickBlox UIKit documentation for more detailed information on the available features and components you can use.

​

Step 3. Adding QBconfig.ts File to Your React Application

To ensure proper configuration and functionality of the QuickBlox UIKit in your React application, it is essential to add a QBconfig.ts file to the src folder. This file allows you to define the necessary parameters for the QuickBlox UIKit. The QBconfig.ts file contains various configuration settings that determine how the QuickBlox UIKit interacts with the QuickBlox JavaScript SDK and the backend services. These settings include:

1. appId: This parameter represents the unique identifier assigned to your QuickBlox application. It helps establish a connection between the frontend and backend components.
2. authKey and authSecret: These parameters are used for authentication purposes. They ensure secure communication between your application and the QuickBlox backend.
3. accountKey: This parameter identifies your QuickBlox account and provides access to the associated services.
4. apiEndpoint and chatEndpoint: These parameters define the API and chat endpoints provided by QuickBlox. They specify the URLs to which the QuickBlox UIKit will send requests for various functionalities.

To illustrate, here is an example of a QBconfig.ts file:

  export const QBConfig = {
    credentials: {
        appId: YOUR_APP_ID_FROM_ADMIN_PANEL,
        accountKey: 'YOUR_ACCOUNT_KEY_FROM_ADMIN_PANEL',
        authKey: 'YOUR_AUTH_KEY_FROM_ADMIN_PANEL',
        authSecret: 'YOUR_AUTH_SECRET_FROM_ADMIN_PANEL',
        sessionToken: '',
    },
    appConfig: {
        chatProtocol: {
            Active: 2,
        },
        debug: false,
        endpoints: {
            apiEndpoint: 'https://api.quickblox.com',
            chatEndpoint: 'chat.quickblox.com',
        },
        on: {
            async sessionExpired(handleResponse: any, retry: any) {
                console.log(`Test sessionExpired… ${handleResponse} ${retry}`);
            }
        },
        streamManagement: {
            Enable: true,
        },
    },
};

In this example, make sure to replace the placeholder values (YOUR_APP_ID_FROM_ADMIN_PANEL, YOUR_ACCOUNT_KEY_FROM_ADMIN_PANEL, YOUR_AUTH_KEY_FROM_ADMIN_PANEL, YOUR_AUTH_SECRET_FROM_ADMIN_PANEL) with the actual values obtained from your QuickBlox application. By adding the QBconfig.ts file to your React application, you ensure that the QuickBlox UIKit is properly configured and can interact seamlessly with the QuickBlox backend services.

Now we can add dependecies in our code. (Open your App.tsx and add that lines.)

import * as QB from "quickblox/quickblox";
import 'quickblox-react-ui-kit';
import { QBConfig } from './QBconfig'; // this line is new

​

Step 4. Updating the project structure according to your needs

In order to enhance the organization and maintainability of your project, it is recommended to make changes to the structure of the App.tsx in the src folder. You need to add a constant called “currentUser” inside the App() function in the App.tsx file, which describes your user registered in the admin panel, and configure the QuickBloxUIKitProvider. Additionally, import the necessary entities from quickblox-react-ui-kit. As a result, you should have the code below:

import React from 'react';
import * as QB from "quickblox/quickblox";
import {
   LoginData,
   QuickBloxUIKitProvider,
   qbDataContext,
   RemoteDataSource,
   useQBConnection, QuickBloxUIKitDesktopLayout,
} from 'quickblox-react-ui-kit';

function App() {

const currentUser: LoginData = {
   		userName: 'YOUR_REGISTRED_USER_NAME',
   		password: 'YOUR_REGISTRED_USER_PASSWORD',
};

	return (
   <QuickBloxUIKitProvider
       maxFileSize={100 * 1000000}
       accountData={{ ...QBConfig.credentials }}
       qbConfig={{ ...QBConfig }}
       loginData={{
           login: currentUser.login,
           password: currentUser.password,
       }}
   >
       <div className="App">
 		<QuickBloxUIKitDesktopLayout/>
       </div>
   </QuickBloxUIKitProvider>
);

}

export default App;

QuickBloxUIKitProvider can accept up to three parameters:

• maxFileSize - controls the maximum size of uploaded files.
• accountData - information about the application’s account data.
• qbConfig - the configuration file structure contains settings such as session duration for the React Kit, keys for interacting with AI features, and so on.
• loginData - information about the logged-in user.

Let’s add the QuickBlox UIKit chat layer - QuickBloxUIKitDesktopLayout - to the markup of the main component of the application.

If we do not specify a sessionToken in accountData, it means that the login and session start process occurs within our application. In this case, it is necessary to perform the following fifth step in our instruction. However, if the session start and application login process is already performed in another application, such as on a server, and we already have a ready sessionToken, then we can skip the next step.

​

Step 5. Configure QuickBloxUIKitProvider

To configure QuickBloxUIKitProvider and use QuickBloxUIKit in your application, follow these steps: Initialize DataContext:

1. To work with QuickBlox, it is necessary to initialize the UIKit react DataContext. It contains important data and settings for using QuickBloxSDK. The DataContext connects various components of the application and provides them access to shared data.

const qbUIKitContext: QBDataContextType = React.useContext(qbDataContext);
  const [isUserAuthorized, setUserAuthorized] = React.useState(false);
  const [isSDKInitialized, setSDKInitialized] = React.useState(false);
  const prepareSDK = async (): Promise<void> => {
    // check if we have installed SDK
    if ((window as any).QB === undefined) {
      if (QB !== undefined) {
        (window as any).QB = QB;
      } else {
        let QBLib = require('quickblox/quickblox.min');
        (window as any).QB = QBLib;
      }
    }
    const APPLICATION_ID = QBConfig.credentials.appId;
    const AUTH_KEY = QBConfig.credentials.authKey;
    const AUTH_SECRET = QBConfig.credentials.authSecret;
    const ACCOUNT_KEY = QBConfig.credentials.accountKey;
    const CONFIG = QBConfig.appConfig;
    QB.init(APPLICATION_ID, AUTH_KEY, AUTH_SECRET, ACCOUNT_KEY, CONFIG);
  };

2. We need to add user authentication, so to do this, we will introduce two states and use the useEffect hook:

const [authorized, setAuthorized] = React.useState(false);
const [initedSDK, setInitedSDK] = React.useState(false);
......
 useEffect(() => {
    if (!isSDKInitialized) {
      prepareSDK().then(result => {
        QB.createSession(currentUser, async function (errorCreateSession: any, session: any) {
          if (errorCreateSession) {
            console.log('Create User Session has error:', JSON.stringify(errorCreateSession));
          } else {
            const userId: number = session.user_id;
            const password: string = session.token;
            const paramsConnect = { userId, password };
            QB.chat.connect(paramsConnect, async function (errorConnect: any, resultConnect: any) {
              if (errorConnect) {
                console.log('Can not connect to chat server: ', errorConnect);
              } else {
                const authData: AuthorizationData = {
                  userId: userId,
                  password: password,
                  userName: currentUser.login,
                  sessionToken: session.token
                };
                await qbUIKitContext.authorize(authData);
                setSDKInitialized(true);
                setUserAuthorized(true);
              }
            });
          }
        });
      }).catch(
          e => {
            console.log('init SDK has error: ', e)
          });
    }
  }, []);

  ......

After implementing all the steps, your App.tsx file should look like this. You can compare it this your code or copy it instead of.

import React, { useEffect } from 'react';

// @ts-ignore
import * as QB from "quickblox/quickblox";
import {
  QuickBloxUIKitProvider,
  qbDataContext,
  QuickBloxUIKitDesktopLayout, LoginData, AuthorizationData, QBDataContextType,
} from 'quickblox-react-ui-kit';
import { QBConfig } from './QBconfig';
import './App.css';

function App() {

  const currentUser: LoginData = {
    login: '',
    password: '',
  };

  const qbUIKitContext: QBDataContextType = React.useContext(qbDataContext);

  const [isUserAuthorized, setUserAuthorized] = React.useState(false);
  const [isSDKInitialized, setSDKInitialized] = React.useState(false);

  const prepareSDK = async (): Promise<void> => {
    // check if we have installed SDK
    if ((window as any).QB === undefined) {
      if (QB !== undefined) {
        (window as any).QB = QB;
      } else {
        let QBLib = require('quickblox/quickblox.min');
        (window as any).QB = QBLib;
      }
    }

    const APPLICATION_ID = QBConfig.credentials.appId;
    const AUTH_KEY = QBConfig.credentials.authKey;
    const AUTH_SECRET = QBConfig.credentials.authSecret;
    const ACCOUNT_KEY = QBConfig.credentials.accountKey;
    const CONFIG = QBConfig.appConfig;

    QB.init(APPLICATION_ID, AUTH_KEY, AUTH_SECRET, ACCOUNT_KEY, CONFIG);

  };

  useEffect(() => {
    if (!isSDKInitialized) {
      prepareSDK().then(result => {

        QB.createSession(currentUser, async function (errorCreateSession: any, session: any) {
          if (errorCreateSession) {
            console.log('Create User Session has error:', JSON.stringify(errorCreateSession));
          } else {
            const userId: number = session.user_id;
            const password: string = session.token;
            const paramsConnect = { userId, password };

            QB.chat.connect(paramsConnect, async function (errorConnect: any, resultConnect: any) {
              if (errorConnect) {
                console.log('Can not connect to chat server: ', errorConnect);
              } else {
                const authData: AuthorizationData = {
                  userId: userId,
                  password: password,
                  userName: currentUser.login,
                  sessionToken: session.token
                };
                await qbUIKitContext.authorize(authData);
                setSDKInitialized(true);
                setUserAuthorized(true);
              }
            });
          }
        });
      }).catch(
          e => {
            console.log('init SDK has error: ', e)
          });
    }
  }, []);

  return (
      <div>
        <QuickBloxUIKitProvider
            maxFileSize={100 * 1000000}
            accountData={{ ...QBConfig.credentials }}
            qbConfig={{ ...QBConfig }}
            loginData={{
              login: currentUser.login,
              password: currentUser.password,
            }}
        >
          <div className="App">
            {
              // React states indicating the ability to render UI
              isSDKInitialized && isUserAuthorized
                  ?
                  <QuickBloxUIKitDesktopLayout/>
                  :
                  <div>wait while SDK is initializing...</div>
            }
          </div>
        </QuickBloxUIKitProvider>
      </div>
  );
}

export default App;

You should run the application using the command:

npm start

Also you can find the project from video here: React Chat UIKit init example.
