The Loro Protocol repo is now open source! It contains documentation for the wire protocol, along with TypeScript and Rust implementations of WebSocket clients and servers. The protocol allows reusing a single connection to join multiple CRDT rooms, such as Loro documents or the Ephemeral Store.

Loro Inspector is here! Now you can directly browse the current state and complete edit history of your Loro documents in the browser. You can also use this tool to time travel to any version in the history of your Loro document.

Just implemented the first working attempt at an Entity-Component API on top of the @loro.dev CRDT. It's a super work-in-progress start to the new Leaf SDK that will be powering @roomy.chat and a.weird.one.

Personal software has been trending recently. I enjoyed reading @leerob.com's "personal software" and @edmarferreira.bsky.social 's "selfish software". Hope you enjoy them too! xuanwo.io/links/2025/0...

Diving into Loro on stream today. Local-first, CRDT library written in Rust. Excited to explore it deeper! Starting in one hour.

It's so hard to feel this warmth from interactions on social platforms these days 🥹

The animated gifs and illustrations in @loro.dev's docs are delightful. Finding these docs to be an enjoyable and readily comprehensible introduction to CRDTs. Thanks @zxch3n.com!

New version control primitives have been added to Loro: - diff(from, to): calculate the differences between any two versions - revertTo(version): Generate ops to revert to the target version - applyDiff(diff): Apply differences You can use them to implement functions like git squash and revert.

just watched DJs coding Haskell live?!

Ok, a rundown of how we get p2p ATProtocol going: 1. Run *standard* ATProto services, locally 2. Use p2p to holepunch TCP connections 3. Add a thin layer for peering management Bundle all that up in an app, and we have a recipe for adding resilience & scaling to Bluesky. 🧵 teim:

Catch the deets at our upcoming LoFi/21 meetup 👉🏽 lofi.so

Finished another skim through the eg-walker paper: arxiv.org/abs/2409.14252, can’t wait to try it out in loro.dev

Join us for #LoFi/21 on Tuesday, November 26th, 2024, @ 8 AM PST 👉🏽 lofi.so. We have yet another exciting lineup featuring Felicia Chang (x/@felchang) from x/@jamsockethq, Sahil Lalani (x/@SahilLalani0) and Zixuan Chen (x/@zx_loro) from x/@loro_dev #localfirst #lofi #meetup

We are developing a local-first map community powered by ATProto - share your favorite cafes, discover your neighborhood, and explore new places wherever you go 🗺️☕️

What happened to npm downloads?

Myers diff may generate weird deltas like the following example. It will make concurrent text updates generate weird merge results. Any suggestions? My current thought is to implement an A* search on top of the edit graph that punishes noncontinuous edits

After revisiting and discussing this issue with @memoryandthought.me , I realized that I might be able to implement it on Loro while ensuring backward compatibility (but not forward compatibility). I will try to make a version to test.

You may experience data loss due to the following issues caused by incorrect usage of CRDTs libraries, regardless of whether you're using Loro, Automerge, or Yjs. Here is how to avoid them:

I've put together a starter pack for anyone interested in local-first! Who else mostly writes about local-first? go.bsky.app/KDasV5R

AT Protocol 貌似也能合法地在大陆部署，因为审核是去中心化的，可以选择性收录账户和内容

If an app needs to support end-to-end encryption, what kind of key management would provide the best UX? Considering that users are likely to forget passwords or lose key files.

iroh's going to 1.0 in 2025!

Loro is on Reddit 🔥

Zixuan has been doing impressive work turning some of our CRDT research into practice

Loro 1.0 is here! Introducing stable binary document format, blazing-fast import speed, Git-like shallow clone, enhanced version control, and more. loro.dev/blog/v1.0

Hello lots of new followers! If you just joined Bluesky, welcome. In case you’re interested how it works under the hood, I helped write this architecture description: arxiv.org/abs/2402.03239 (updated with new content just a few days ago)

Big news: I'm working with @chris.blue on a second edition of Designing Data-Intensive Applications! An early release of the first 3 chapters is now available: learning.oreilly.com/library/view... (O'Reilly Learning subscribers only at this point) and we're hoping to finish it next year.
