Yjs features and specs

  • Real-time Collaboration
    Yjs enables real-time collaborative editing, allowing multiple users to work on the same document simultaneously without conflicts.
  • Conflict-free Replicated Data Type (CRDT)
    Yjs employs CRDTs to automatically resolve changes and conflicts, eliminating the need for complex merging algorithms.
  • Scalability
    The framework is designed to efficiently handle a large number of users, making it suitable for large-scale collaborative applications.
  • Offline Editing
    Yjs supports offline editing, allowing users to make changes while disconnected from the network and synchronizing them once back online.
  • Language Agnostic
    Yjs can be integrated with different programming languages, making it flexible for various tech stacks.
  • Open Source
    As an open-source library, Yjs provides full transparency of its codebase and fosters a supportive community for continuous improvement.

Possible disadvantages of Yjs

  • Complexity of CRDTs
    While powerful, CRDTs introduce a level of complexity that might be challenging for developers unfamiliar with distributed systems.
  • Learning Curve
    Developers may need time to understand and effectively implement Yjs, especially if they are new to real-time collaboration frameworks.
  • Integration Overhead
    Adding Yjs to an existing application might require significant changes in the architecture, particularly if the app wasn't initially designed for real-time collaboration.
  • Performance Overhead
    Handling a large amount of operational transformations in real-time can introduce performance overhead, especially in less optimized implementations.

  • Multi-player Mode is Everywhere, Even in Dev Tools
    Of course, you don’t have to code this functionality from scratch! You can also look at open-source software like Yjs, text-crdt, Automerge and so many more. Alternatively, you can check out tools like Liveblocks, Ably, etc. Which enable collaborative multi-player features. - Source: dev.to / 4 months ago
  • Show HN: JuntOS – A shared Pomodoro and focus tools
    I've built this app some time ago but only shared with close friends. It has been useful for me so I decided to share here. It works by sharing state with yjs [1], as long as you are in the same session, i.e. The same path. https://github.com/yjs/yjs. - Source: Hacker News / 7 months ago
  • Oops.js
    I write undo/redo/history in web/JS extensively. This the best lib out there for such tasks IMHO: https://github.com/yjs/yjs And you're right. You don't want undo/redo only in multi-user apps. You want to have each user have their own local undo/redo events that they can apply and unapply from the shared state which has its own events apart from each user. Everyone... - Source: Hacker News / 9 months ago
  • Oops.js
    After reviewing the ~600 lines of code, I have to ask what about this undo/redo manager is "advanced"? This seems like a naive implementation of a snapshot collection that is selected via array index. It's not event sourcing, OT or CRDT. With every event, the entire object is serialized and put into the heap. I can't even imagine what this does for performance when you deal with any object of significant size.... - Source: Hacker News / 9 months ago

    I've seen it come up often in collaborative text editors. Also see: https://github.com/yjs/yjs. - Source: Hacker News / over 1 year ago
