Hey there ​@Nur Nahid! Emily here from Support Engineering

Yes, it is possible to integrate Intercom live chat with a React.js website! 
React is a framework for building Single Page Applications (SPAs), and Intercom supports this type of integration

To set up Intercom on your React app, you will need to follow the SPA installation method, which includes including the Intercom JavaScript library file in your HTML head element and making additional JavaScript calls to manage the messenger's visibility and user sessions.
You can find the complete guide for integrating Intercom into a single-page app here

Hope this helps!

Hey ​@Emilygav thanks for your valuable words. 

No problem ​@Nur Nahid  Have a lovely day!

You too!
