Sample App (If you do not have an existing app)

1) Get Your SDK License Key

Follow the below steps to obtain the License key from MirrorFly’s official website.

Step 1 : Go to MirrorFly’s Console Page

Step 2 : Provide the basic account information

Step 3 : Verify your account using your registered email

Step 4 : Sign into your MirrorFly account.

You will be taken to your Account Overview Page . On this page, you will be able to find the downloadable JavaScript SDK files and your License Key.

Step 5 : From the Application info section, copy the License Key.


2) Chat SDK Integration into Web App

In this section, you’ll learn how to integrate Chat SDKs in Javascript, Angular, React and React native.

Chat SDK Integration : Javascript

Step 1 : Download the Javascript SDK files from your MirrorFly Account

Step 2 : Extract the files from the downloaded ZIP folder

Step 3 : Copy the SDK files into your application

Step 4 : After copying, include the script file into your index.html

                     <script src="./index.js">
                     <script src="./">

Step 5 : You can now start the initialization with the available SDK object

Step 6 : Once your Javascript SDK is integrated, you may proceed with the chat implementation in any of the programming languages preferred by your clients.

Chat SDK Integration : Angular

Note: Minimum Angular requirement is version 8.3.29

Step 1 : In your project’s root directory, create a new folder

Step 2 : Paste the extracted SDK files

Step 3 : Open angular.json

Step 4 : Navigate to build > options > scripts

Step 5 : Add file paths to your SDK JS files

Step 6 : Before the Component decorator in the root component, add the below code in ngOnInit

                     declare var SDK: any;

Step 7 : Within Angular's initialization method, initialize our SDKs.

Chat SDK Integration : React

Step 1 : In the index.html, include your script file

                     <script src="./index.js">
                     <script src="./">

Step 2 : In the project root, create a new file SDK and paste the below code.

                           const SDK = window.SDK;
                              export default SDK;

Step 3 : Import the SDK into your app

                           import SDK from "./SDK";

Chat SDK Integration : React Native


Peer Dependencies Required Version
Node 14.20.0
react-native Any
npm 6.14.10
react-native-document-picker >=8.1.1
@react-native-async-storage/async-storage Any
react-native-get-random-values 1.7.1

Step 1 : Check for packages.json files and update them

Step 2 : Check for any duplicate package files (if they are not working on iOS)

Step 3 : From the dist folder, copy all the extracted files

Step 4 : Inside your project, paste all the SDK files

Step 5 : Export the SDK objects into a SDK.js file

                            import './index';
                           const SDK = window.SDK;
                           export default SDK; 

3) Chat SDK Initialization

To initialize the SDKs, you’ll need a set of data that can respond to the connection status changes in the client’s app. To pass these data, use the below method along with the License Key parameter.

                      //For chat logging 

4) User Registration

Step 1 : Use the connect method to establish server connection

                      await SDK.register(`USER_IDENTIFIER`);

You’ll receive a response similar to the section below:

                         statusCode: 200, 
                         message: "Success", 
                         data: { 
                            username: "123456789", 
                            password: "987654321" 

Step 2 : You can use the ConnectionListener callback to trace the connection status of the chat SDK with the MirrorFly server.

                      await SDK.connect(`USERNAME`, `PASSWORD`); 

5) Send Messages

Once the server connection is achieved, use the below method to send messages from your web chat app

6) Receive Messages

Implement the messageListener function to receive messages on your web chat app. Next, add the below callback method to initialize the SDK

                        function messageListener(response) { 
                         console.log("Message Listener", response); 


As seen from this tutorial, you’ll now be able to develop your own web chat apps in just 6 steps. If you’d like to take a step further with adding other functionalities, here are some of our tutorials you may need to check out:
