Lexical

Type: editor engine reference

Lexical is the strongest modern runtime challenger in this lane.

Why it matters

• separates mark ids from comment/thread stores
• separates decorator UI from text overlays
• gives a better invalidation/runtime posture than legacy Slate

Strongest local evidence

• ../lexical/packages/lexical/src/LexicalUpdates.ts
• ../lexical/packages/lexical-mark/src/MarkNode.ts
• ../lexical/packages/lexical-playground/src/commenting/index.ts
• ../lexical/packages/lexical-playground/src/plugins/CommentPlugin/index.tsx
• ../lexical/packages/lexical-react/src/useLexicalSubscription.tsx

Limits

• not a reason to copy Lexical’s whole node model
• playground comment code is product evidence, not universal law
• the strongest challenge here is the explicit dirty-node reconcile model
