What is React-Native Armia Chat-SDK

The React Native Chat SDK makes it easy to build in-app chat like WhatsApp, Facebook messenger, Signal app, which can easily be done through Chat SDK. Users can easily add chat functionality on their mobile as well as on desktop. The react native armia chat SDK library includes components you need to build a functioning chat user experience in React with one-to-one and group chat support.

Users can send audio and video messages, exchange photos and files. It uses Firebase as the backend service. You can download the FREE SDK to save months of development time from your project using the Chat SDK. If you are hosting in your own infra, there is no cost. If you want to host it in our infrastructure, there would be a hosting cost for more than 1000 chats per month. How does SDK work within a mobile app?

The SDK takes care of the basic functionality requirements for any chat application.

In this project, We have used the following Firebase services.

  • Firebase Authentication: For authentication user by phone number

  • Firebase Storage: That’s we use to store user profile image

Why to Choose React Native For Chat App Development?

  • Availability of Developers If you require it
  • Lower Development Cost
  • Reusable UI Components
  • Compatibility to Cross-Platform

React Native is a technology focused solely on building mobile apps using the platform node.js, Android Studio/ Expo Client App. React Native uses ReactJS as the JavaScript library, which enables it users to have all its advantages.  To build a cross-platform app with React Native, the language of the native platform needn’t be known by developers. They should be familiar with JavaScript and be familiar with the React syntax. They can also add a native component to the code.

React Native requires Bridge components to be written for each platform to use them. It brings it back closer to a hybrid framework. But in the case of React Native, you needn’t be anxious about the platform specific behaviors in providing the most seamless experience for your users.

If you have decided to build chat functionality in the client app, then React Native is one of the most popular frameworks. Our Chat SDK allows you to configure, build, and integrate chat functionality into any web or mobile app. If you have any questions concerning how to build chat app functionality into your app, contact our business development team for a consultation. Our development team is available for integrating text, audio, video chat functionality to your mobile apps or build a new chat app using the Chat SDK.
