    A drop-in javascript spreadsheet library that provides rich features like Excel and Google Sheets

    I posted this project to r/reactjs a couple of weeks a ago and received many feedbacks. It's more refined now and I would like share with r/webdev too! It's like Google Sheets, and completely open source. Github: https://github.com/ruilisi/fortune-sheet Live Demo: https://ruilisi.github.io/fortune-sheet-demo BTW, one thing to be mentioned is that in the collabration demo, I didn't use any OT or CRDT algorithms to ensure all clients are strictly synchronized. There're chances that one client make changes that collides with another client (e.g. editing the same cell), and result in different state. Any ideas of improving this?

  • yjs

    Shared data types for building collaborative software

    Checkout yjs it uses CRDTs https://github.com/yjs/yjs

  • Appwrite

    Appwrite - The Open Source Firebase alternative introduces iOS support . Appwrite is an open source backend server that helps you build native iOS applications much faster with realtime APIs for authentication, databases, files storage, cloud functions and much more!

  • automerge

    A JSON-like data structure (a CRDT) that can be modified concurrently by different users, and merged again automatically.

    And about conflict --as already mentioned in comments-- CRDTs is the way to go here. Automerge is an implementation you may want to look into.
