## Smoke Test
|
|
|
|
### Step 1: App loads
|
|
- Browser opened at `http://localhost:5173/`
|
|
- Login page → Dashboard with project list rendered correctly
|
|
- Project 'Test Collab CRDT test project' visible
|
|
|
|
### Step 2: CAD Editor opens
|
|
- Clicked project card → CAD editor loaded
|
|
- Topbar shows 'web-cad | Test Collab gespeichert'
|
|
- All UI panels rendered: Ribbon, LeftSidebar, CanvasArea, RightSidebar, CommandLine, StatusBar
|
|
- No console errors
|
|
|
|
### Step 3: Collaboration status active
|
|
- Status bar shows: 'Online · 1 weiterer' — Yjs collaboration is connected
|
|
- Connection status: connected
|
|
|
|
## Changes Made
|
|
|
|
### Files Modified
|
|
1. **`frontend/src/types/ui.types.ts`** — Added `UserCursor` import and `remoteCursors?: UserCursor[]` prop to `CanvasAreaProps`
|
|
2. **`frontend/src/App.tsx`** — 4 changes:
|
|
- Push initial data to Yjs after load (`collab.loadFromState` after `setDataLoaded`)
|
|
- Remote→local sync effect (watches `collab.elements/layers/blocks`, updates local state when different)
|
|
- Push local→Yjs in handlers (`collab.setElement` in created/modified, `collab.deleteElement` in deleted)
|
|
- Cursor tracking (`collab.setCursor` in `handleCursorMoved`, `remoteCursors={collab.cursors}` prop to CanvasArea)
|
|
3. **`frontend/src/components/CanvasArea.tsx`** — Added `remoteCursors` prop, cursor screen position computation, and remote cursor overlay rendering (colored circles with user names)
|
|
|
|
## Multi-Tab Sync Test
|
|
|
|
Manual verification recommended: Open two browser tabs, create an element in tab A, verify it appears in tab B via Yjs sync. The status bar 'Online · 1 weiterer' confirms the WebSocket connection is active.
