A CRDT framework with a powerful abstraction of shared data
Yjs is a CRDT implementation that exposes its internal
data structure as shared types. Shared types are common data types like Map
or Array with superpowers: changes are automatically distributed to other
peers and merged without merge conflicts.
Yjs is network agnostic (p2p!), supports many existing rich text
editors, offline editing, version snapshots, undo/redo and
shared cursors. It scales well with an unlimited number of users and is well
suited for even large documents.
