CRDT Algorithm for Collaborative Text Editing in Peer-to-Peer Applications
By
skadamat
A baker's-dozen of insight crammed into one ring.
Summary
This article presents a CRDT (Conflict-Free Replicated Data Type) algorithm for collaborative text editing in peer-to-peer applications. It describes an approach for handling concurrent edits to text buffers without conflicts, similar to popular libraries like Yjs and Automerge. The algorithm enables real-time collaborative editing where multiple users can edit the same document simultaneously while maintaining consistency across all peers.
