Pattern Decisions This Source Supports

Pattern Supported decision Required contract Claim note
Live cursors Choose live cursors when users need immediate spatial awareness of other collaborators' current pointer, caret, selection, viewport, or focus inside the same shared surface. Sending cursor data updates ephemeral awareness state with coordinate, target, viewport, selection, identity, color, timestamp, and visibility preference, not the saved document content. Yjs awareness API documents user status, cursor location, username, and email address as network-agnostic CRDT state.
