Скачать или смотреть Add Real-Time Collaboration to CKEditor 5 in React | Notes App Tutorial (Vite + TS + Vercel)

Turn your solo note-taking app into a live, multi-user workspace!
In this third episode, I add CKEditor 5’s *Real-Time Collaboration* (presence-list & revision
history) to the personal-notes app generated in video #1 and enriched with CKEditor features in
video #2. You’ll see how to regenerate the editor build, merge the diff into existing code, wire a
unique document-ID for each note, and test two browsers editing the same doc simultaneously.

🔑 What you’ll learn
• Quick repo & live demo recap
• Using CKEditor Builder to add *Real-Time Collab* & Revision History
• Merging CSS/TSX diffs instead of copy-pasting a fresh scaffold
• Exposing license + API keys via `.env` (and why `VITE_` prefix leaks!)
• Passing each note’s GUID as `channelId` so every document gets its own room
• Simple share-by-URL flow: open unknown GUID → create stub note → sync edits
• Persisting edits in LocalStorage for guest users
• Live test with two browser windows; version-history tour
• Caveats: race-conditions, user naming, security tips
