I came back from Sync Conf and shocked how many people are building text editors and the struggles they had with yjs. So rather than wait for my cofounder to finish his blog, I’ll just give a quick rundown on what we do for live collab editing.

Changelog 3 is out. Mostly we were busy with Sync Conf, the American holiday known as veteran's day, and 😱 replacing our frontend state management system. 😱 But we are looking forward to some very big product announcements in the next couple weeks. moment.dev/blog/changel...

We evaluated a lot of frameworks (this was back 2-3 years ago so keep that in mind). As you can tell from our blog, yjs did not cut it for us.

We ended up building a centralized stateful service that optimistically writes with a transaction log. Thats it. Nothing algorithmically fancy. Boring systems stuff.

We did start with durable objects but ended up partnering with reboot.dev and been satisfied. Performance is great and reboot clients handles the reactivity and idempotency for us.

We use github.com/nytimes/reac... for our render layer vs tiptap as we think working prosemirror transitions gave us better correctness and performance.
