Automerge: A JSON-like data structure (a CRDT) that can be modified concurrently

• automerge

  A JSON-like data structure (a CRDT) that can be modified concurrently by different users, and merged again automatically.

  

  Unless I'm mistaken, according to their own TS types[0], `Automerge.merge` should return a `{ readonly [P in keyof T]: Freeze }`. Getting `undefined` here is probably a bug.

  A CRDT for asynchronous rich-text collaboration, where authors can work independently and then merge their changes.

  

  An interesting challenge in the CRDT era today, is that there isn't an ideal CRDT for rich text yet. When I mean rich text, I expect simple boundary based formattings like bold/italics but more importantly complex block based elements like tables and lists.

  While recent CRDTs like peritext has done an incredible job of focussing on this specific problem of rich text, even that project hasn't extended its types to cover table operations and list operations. I've been thinking about this problem deeply and my intuition is that anything that resembles semantic trees are tricky to deal with using a generic CRDT.

  For example a generic tree/json CRDT cannot be used for an AST tree - and it will most likely fail. I wrote about this a while back - https://news.ycombinator.com/item?id=29433896
