Yjs - CRDT-based collaborative editing framework. - Source: dev.to / 3 months ago

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 / 9 months ago

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 / 12 months ago

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 / about 1 year ago

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 / about 1 year ago

In a recent (abandoned) project, I used Reflect: https://reflect.net/ It was by far the most developer-friendly experience I've had trying to implement collaborative editing. The one thing it didn't have that YJS did was built-in undo/redo. - Source: Hacker News / about 1 year ago

Crazy plot twist (last minute edit): As I was about to publish this post I discovered that Replicache is going to be opened sourced in the near future and that its parent company is planning to launch a new sync-engine called "Zero". Here is the official announcement. It reads: "We will be open sourcing Replicache and Reflect. Once Zero is ready, we will encourage users to move." Ironically, Zero seems to be yet... - Source: dev.to / over 1 year ago

As the Monday began I started reading documentation and looking into the tech I wanted to use. For most of the stack I went with things I know. But for the multiplayer part I had to read up and understand the core concepts behind Replicache. While reading I came across their hosted service Reflect. This was a perfect fit as time was of the essence and I would not have to build my own Replicache backend! It's... - Source: dev.to / over 1 year ago
