  • Ask HN: What Are You Working On? (October 2024)
    A sqlite extension that provides a virtual table backed by an Automerge document (https://automerge.org/). I believe that there are plenty of applications that could benefit from the collaboration or sync-ability that CRDTs provide, but that don't need to manage the CRDTs directly. Moving the CRDT management into the database seems like a natural fit. It's very early, and not public anywhere, but I'd be happy to... - Source: Hacker News / 6 months ago
  • Comparing local-first frameworks and approaches
    Ink & Switch released automerge to automatically achieve this merge. If you have two documents you are collaboratively editing, you can use automerge to make concurrent changes. - Source: dev.to / 7 months ago
  • 5000x Faster CRDTs
    > The most popular, highly ergonomic, best implementations of CRDTs actually break the academic rules of CRDTs. There's a popular, highly ergonomic implementation called Automerge[0] that would beg to disagree with you. [0]: https://automerge.org/. - Source: Hacker News / 8 months ago
  • Using CRDTs to build collaborative Rust web applications
    If you plan to build production-grade CRDT-based software and don’t want to build every piece of it by hand, I recommend Automerge as a library for handling all your CRDT needs, but it’s always good to look under the hood to build intuition and understanding for the underlying concepts. - Source: dev.to / about 1 year ago
  • Figma Is a File Editor
    Take a look at https://automerge.org/ and the stack those folks are building. You're exactly right that it's a difficult balance (specifically the trick is proving commutativity for the domain-specific data of your application). But automerge (and then https://github.com/inkandswitch/peritext) show it's at least possible. Good stuff. - Source: Hacker News / almost 2 years ago
