CRDT – Conflict-free replicated data type
CRDT or Conflict-free replicated data type is ‘a data structure which can be replicated across multiple computers in a network’
See https://en.wikipedia.org/wiki/Conflict-free_replicated_data_type
See demo project for a collaborative Markdown editor https://www.npmjs.com/package/crdt-md-editor
See also operational transformation, the convergence algorithm used by Google docs and Ms Office online.
CRDTs allow for a consistency model called Eventual consistency.
See Peritext, a rich-text CRDT developed by Ink & Switch. Github, Essay
See 5000x faster CRDTs: An Adventure in Optimization (Recent article 2021-07-31 about CRDT speed)
Here the author Seph Gentle recommends using Yjs for any kind of production set-up.
