Hello chandradev819,

We have a guide here on how to setup collaboration! [PDF.js Express Real-Time Collaboration | Documentation](https://pdfjs.express/documentation/collaboration/overview)

Hi @tgordon Thanks for reply. I saw your official document on this topic.  
In that document, It was only with Nodejs with firebase.

Could you help me to give code sample with only html and JavaScript?  
is it mandatory to use NodeJS and Firebase?

Hello chandradev819,

Yes it does require Node and Firebase, since it requires a server to act as a host between the two clients.  
In realtime collaboration, a server will merely act as an online database that triggers events upon data creation/modification/deletion. As long as the above requirement is met, your server can be built in any language and stack of your choice. For the simplicity of this guide, we will be using [Firebase](https://firebase.google.com/).
