build react native chat app

Building a fully functional chat app using the best-in-class React Native chat SDK library is now simple & quick. Want to know how? Let’s get started .

In this tutorial, we will cover every detailed guide on how to integrate React Native chat components to build your app? with enriched features of sharing video, image uploads, read state, reactions, threads, and much more.

Let’s begin!

Why To Choose React Native?

React Native is a JavaScript framework meant for writing real, natively rendering mobile applications like iOS and Android. It gives space to the developers to share the same codes across multiple platforms to build their chat app. Furthermore, it has the potential to expand to future platforms as well. 
Some of the social media platforms like Facebook, TaskRabbit, and Palantir, are utilizing React Native in production for better user-facing applications.

8 High-end Benefits of A React Native Chat App

  • Highly Compatible across the Platforms – specifies that the application that has been coded for Android can also be shared for iOS, which indeed save time as well as cost.
  • Robust Community – this provides access to the user support and many other user created tools.
  • Cost Effective and Time Saving – as you can create a single app and use it for both iOS as well as Android.
  • Top Reloading Feature – works across all the mobile platform with ease.
  • OTA (Over The Air) – an innovative update that enables the developers to let their users create and administer the recent updates.
  • Highly Flexible – this allows any number of developers to work on the app project at once without any interruption enabling them to add any number of features.
  • Open Source Framework – this attribute provides the developers with an easy accessibility to migrate from one platform to another.

How to Create A React Native App for Web & Mobile

To make this tutorial section much easier for you to understand, let’s get into the technical part of this react native chat app development for web applications.

Here, we will see a steps-by-step process to build a React Native chat app.

Step 1 – Build a Sample App – This process involves,

  • Installing Modules
  • License Key
  • Run the Application

Step 2 – Integrate Sample App into an Existing Application with the below set of processes

  • Initialize SDK
  • Register
  • Login
  • Update User’s Profile

Create a React Native Chat App for Web

Whether you want to develop a new react native chat app or integrate the chat features into the existing web application, all you need is our sample app with a sandbox SDK.  Yes! our chat comes with a fully functional UI component that makes the entire development process more simple to add chat to your web.

So with all the backend coding part, Let’s get into the detailed description of these above mentioned steps

Step 1 – Install npm modules in the project’s root directory

npm install

Step 2 – Add License key in.env.uat file and validate the rest of the configurations – here the Sandbox endpoints are pointed out as default.

Step 3 – Use the below said command to run the application

npm run start:sandbox 

As soon as the execution is done, the application will run on http://127.0.0.1:3000 or http://localhost:3000

Step 4 – Integrate the Sample App into the Existing Application

If you want to integrate the MirrorFly’s UI into an existing web app then you have to follow the below mentioned methods

Step 5 : Initialize SDK into your application

const initializeObj = { 
   xmppSocketHost: `HOST`,
  xmppSocketPort: `PORT`,
   ssl: `SSL`,
   encryptKey: `ENCRYPT_KEY`,
   apiBaseUrl: `API_URL`,
  licenseKey: `LICENSE_KEY`,
  isSandbox: `SANDBOX_MODE`,
   callbackListeners: {},
  signalServer: `SIGNAL_SERVER`,
   janusUrl: `JANUS_URL`,
   };
   await SDK.initializeSDK(initializeObj);

Step 6 : You need to call the Register SDK method to create a new user profile using license key

await SDK.register(`USER_IDENTIFIER`);

Proceeding further, for both Request and Responses need to refer below method

Register

To begin with there is a need to create a new user account

If you get the autoLogin as true, then this will enable the user to login with XMPP after successful registration.

Note – If the sandbox mode is set to true, then the users will register into the sandbox mode at the startup itself.
await SDK.register(`USER_IDENTIFIER`, `AUTO_LOGIN`);

Sample Responses - 

If autoLogin is true

{
statusCode: 200,
message: "Login Success"
}

if autoLogin is false

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

Now use the credentials that has been received from the Register response, login using SDK

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

Check for further Request and Responses

Example Request

Image as a URL

 await SDK.setUserProfile(
 "Name",
 "https://domain/path/image.png",
 "status",
 "1111111111",
 "email@domain",
  );

Image as a FILE

await SDK.setUserProfile("Name", FILE, "status", "1111111111", "email@domain");

When you want to sync the contacts with the License Key, use can use the Sync Contact Method

await SDK.syncContacts(`USER_IDENTIFIER`);

Once the entire process of registration and sync gets completed, you can refer to other profiles using one-to-one chat, and group chat methods.


Well, after having a better clarity with the importance of implementation of React Native in your chat app. Let’s get some ideas about the market launch strategy.

Key Points to Be Considered Before Launching a React Native Chat App!

The main target of every application is to reach the market, but this is not an easy journey. Let’s have a look at some of the key points that every react native chat app has to be considered before making market launch

  • Chat Performance & Reliability : Once the chat app using react native SDK is developed, it is time for it to be tested for its performance and reliability. The performance issues will be detected upon real-time experience with perceptible latency, undelivered messages, or any app crash during the course.
  • Privacy & Security Protocols : The legal issues like Terms of use and privacy policy is considered to be one of the major issues as they need to be very accurate and must be prepared under the survillenance of a lawyer before launching through play store.
    However, there are many other factors too but above mentioned are some major points for better understanding. Now, let’s see with CONTUS MirrorFly being the one for this entire react native chat app development.
