• Centralized vs. Decentralized: Why Modern Collaborative Tools choose CRDTs

  In the architecture of my Collaborative-Code-Editor, choosing CRDTs over OT gives me the advantage of not depending on a server for my data conflicts. Using Yjs as my CRDT library, not only fixes the problems OT arises but comes with additional features. A unique identifier keeps track of the characters' identity, and relative addressing that points to the character position in my code editor. The relative... - Source: dev.to / 2 months ago

• Show HN: Opensidian: Local-first notes in the browser with POSIX shell and sync

  ``` Those commands create and move real files that immediately appear in the editor's file tree. The best part is that all of this works in both browser and server-side contexts, since yjs (https://github.com/yjs/yjs) is isomorphic. Under the hood, metadata (name, parent, timestamps) lives in a versioned CRDT table. Document content lives in a separate Y.Doc per file, so the directory index syncs without pulling... - Source: Hacker News / 4 months ago

• Local-First Software: Why the Future of Apps Doesn't Need the Cloud

  Libraries like Automerge and Yjs have gone from academic curiosities to production-ready tools. They handle edge cases that would have made local-first apps unreliable five years ago. - Source: dev.to / 4 months ago

• Show HN: µJS, a 5KB alternative to Htmx and Turbo with zero dependencies

  I really like these sorts of frameworks from an architectural perspective, but what's the use-case? Maybe I'm too SPA-pilled, because to me all the fun of Web development is in providing really fluid, skeuomorphic experiences like those enabled by, eg pragmatic-drag-and-drop[0] or yjs[1]. I just struggle to envision what application benefits from the efficiency that this or htmx offer, but from neither the... - Source: Hacker News / 5 months ago

• JupyterGIS breaks through to the next level

  JupyterLab does use CRDT via yjs (https://github.com/yjs/yjs), and the JupyterGIS collaboration system is based on the service provided by JupyterLab. So multiple users can edit the file concurrently. - Source: Hacker News / 9 months ago

• 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 / over 1 year 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 / almost 2 years 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 / almost 2 years 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 / almost 2 years ago

• JSON Schema Store

  You are absolutely right that XML is better for document structures. My current theory is that Yjs [0] is the new JSON+XML. It gives you both JSON and XML types in one nested structure, all with conflict free merging via incremental updates. Also, you note the issue with XML and overlapping inline markup. Yjs has an answer for that with its text type, you can apply attributes (for styling or anything else) via... - Source: Hacker News / almost 3 years ago

• Wormholers, what can CCP and wormholers do to improve J-Space?

  CCP needs to revamp proto anyway, due to recent exploits... practically, nothing really prevents 'em from using some sort of CRDT's to make the state of the sig view eventually consistent (yjs lib, if we're speaking frontendian). Source: about 3 years ago

• Show HN: Nostr-CRDT – real-time collaborative apps over Nostr

  Hi HN! Nostr-CRDT is an experimental project that connects Yjs [1] (a proven, high performance CRDT) with Nostr [2]. I wanted to learn about the Nostr protocol and see if it'd be possible to send updates to state (e.g.: edits of a rich text document, updates to a todo list) over Nostr. Nostr describes itself as "The simplest open protocol that is able to create a censorship-resistant global "social" network once... - Source: Hacker News / over 3 years ago

• Show HN: Pg_CRDT – an experimental CRDT extension for Postgres

  A _lot_ of the heavy-lifting is done by the teams at Yjs[0] and Automerge[1], who have re-implemented their JS libs in Rust. This made it possible for us to wrap them into a Postgres extension using pgx[2] (which is fast becoming a de-facto tool at supabase) [0] Yjs: https://github.com/yjs/yjs [1] Automerge: https://github.com/automerge/automerge [3] pgx: https://github.com/tcdi/pgx. - Source: Hacker News / over 3 years ago

• CRDTs: A Beginner's overview for building a collaborative app

  There are a lot of implementations of CRDTs out there. In JavaScript, for instance, we have Y.js (https://github.com/yjs/yjs) and automerge (https://github.com/automerge/automerge). There’s also a Y.js demo (https://demos.yjs.dev/prosemirror/prosemirror.html) that allows you to play around with them and have your own collaborative app running in just a few seconds.
