I made a fun little thing over the weekend that had been on my mind since the local-first conf. I combined @ethersync and the Language Server Protocol to enable some kind of real-time collaboration in Helix.

I use the "textDocument/didChange" event to track editor's changes and convert them to an edit message in Ethersync.

When a peer makes changes, the other peer receives them from the Ethersync daemon and converts them into a "workspace/applyEdit" message.

Also thinking about using inlay hints for showing other peer's cursor

I'm not sure if that will even be able to work properly, but it's worth trying anyway

#localfirst doesn't have to be about collaboration.

you can 100% have a #lofi app that stores data on your laptop, desktop, and phone without ever engaging a second human being.

multiplayer is cool — but you don't have to solve the hardest problems first.

In a month I'm starting a bi-weekly-ish "p2p lecture" series in @offline!

It's about radical peer-to-peer, local-first, convergent data-types and networking.

14.10. at 7pm is the first session.

This is the most fun you’ll have choosing your next #LocalFirst#OfflineFirst stack:

https://www.localfirst.fm/landscape

You’ll find @pouchdb and @couchdb in there too, with filters to help you maximise compatibility for your next use case

Thanks to @localfirstfm for putting it together ✨

OUT NOW! Our Part II Blog Post on building a convergent, offline-first Access Control CRDT!🍿🪩🧨

https://p2panda.org/2025/08/27/notes-convergent-access-control-crdt.html

Integrity, Provenance, Partial Ordering, Linearization, Concurrency, Conflicts, Consensus, Finality, Equivocation, Byzantine Fault Tolerance and Eventual Consistency, ..

This contains a lot of notes about what you might want to know when building a data type which should be collaborative, convergent and decentralized.

Our own @janl presented “How to Sync Anything” at the latest #LocalFirst Meetup.

He introduced approaches to replication, plus why @couchdb handles it so well from the get-go.

The one thing I’m trying to establish is that sync is a safer abstraction over a network than any manual API goo much like foreach() or map() are safer iteration primitives than a a manually indexed for(let idx=0; idx<list.length; idx++) {} loop. Wdyt? #OfflineFirst #LocalFirst

My lightning talk about How to Sync Anything from the #LocalFirst meetup last week is online: https://www.youtube.com/watch?v=3983rz8ja1U

It was great fun, especially the (not recorded, sorry) discussion afterwards.

It’s been a challenge to cram all that info into 15 minutes and I’m going fast, but I hope I captured all the important points in enough detail.

Ich habe im @workingdraft Podcast von Local-First erzählt. Hat nur zwei Stunden gedauert und wir hätten noch Themen für mindestens weitere sechs 😅

Es hat sehr viel Soaß gemacht, ich hoffe dass das rüber kommt 🙏

Wenn ihr noch Fragen habt: AMA!

I’ll be talking about How to Sync Anything at the Local-First LoFi/#29 event tomorrow night.

You can join via the LoFi Discord (don’t @ me): https://lofi.so

See you there! o/
