  Liveblocks is a platform to ship collaborative features like comments, notifications, text editors in minutes instead of months.

  

You should look at CRDT. I just saw this a few days ago: https://liveblocks.io

• SurveyJS

  surveyjs.io sponsored

  Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.

  Shared data types for building collaborative software

  

I think you might be looking for a CRDT implementation. Yjs is a popular one: https://github.com/yjs/yjs

  Realtime database backend based on Operational Transformation (OT)

  

This is called Operational Transformation, and there are a few libraries to help with it. One that looks fairly mature is https://github.com/share/sharedb
