- Cloudflare Worker + Durable Object server (packages/collab/)
- One DO per room with WebSocket Hibernation for near-zero idle cost
- Yjs sync protocol for document state (CRDT merge)
- Yjs awareness protocol for cursors, selection, presence
- Persists doc state to DO storage
- CORS headers for cross-origin WebSocket upgrade
- Client composable (src/composables/use-collab.ts)
- Y.Doc ↔ SceneGraph bidirectional binding
- Awareness: broadcasts cursor position, selection, name, color
- Auto-join from /share/:roomId URL
- Suppresses echo loops between Yjs and graph updates
- CollabPanel component (src/components/CollabPanel.vue)
- Share button generates room link, copies to clipboard
- Join flow: paste link or room ID
- Avatar stack with colored initials and tooltips
- Name input persisted to localStorage
- Remote cursor rendering in CanvasKit
- Colored arrow cursor + name label pill per remote peer
- Remote selection outlines in peer's color
- Only shows cursors on the same page
- SPA redirect for /share/* routes (Cloudflare Pages _redirects)
expanded: was mapped from frameMaskDisabled (unrelated Kiwi field),
now defaults to true. strokeMiterLimit: was mapped from speculative
strokeMiterAngle field that doesn't exist in Kiwi codec, now uses
hardcoded default 4.
- Replace _id/_graph/_api with Symbol-keyed properties so eval scripts
can't access SceneGraph internals directly
- fills/strokes/effects return frozen structuredClone copies
- Fix currentPage getter to define selection only once per proxy
- Fix layoutSizingHorizontal/Vertical: respect parent layout direction
even when the node itself is an auto-layout frame
- Add 6 new tests: layoutSizing, frozen arrays, internals not exposed
- sceneNodeToJsx() in @open-pencil/core: converts SceneNode subtree to JSX
- CodePanel.vue with Prism.js highlighting, line numbers, copy button
- Third tab in properties panel: Design | Code | AI
- 14 new tests covering shapes, text, layout, effects, multi-selection
- Track click count with timing/proximity in onMouseDown
- Double-click in text: select word (was only handled in dblclick)
- Triple-click in text: select all
- Double-click to enter editing: select word at click position
- Add selectLine/selectLineAt to TextEditor
Replace src/kiwi/ copies with re-exports from @open-pencil/core.
Extract shared sceneNodeToKiwi into kiwi-serialize.ts, used by
both fig-export.ts and clipboard.ts.
jscpd: 15.6% → 1.7% duplication (35 → 18 clones, -4459 lines)
- analyze colors: color palette usage with clustering
- analyze typography: font/size/weight distribution
- analyze spacing: gap/padding values with grid check
- analyze clusters: repeated patterns (potential components)
- node: detailed properties by ID
- pages: list pages with node counts
- variables: list design variables and collections
StyleRun model: array of {start, length, style} with
CharacterStyleOverride (fontWeight, italic, textDecoration, etc.).
Renderer uses ParagraphBuilder.pushStyle/pop for mixed-style text.
TextEditor delegates paragraph building to renderer.buildParagraph().
⌘B/I/U apply to selection range when text is selected, or toggle
whole-node style when no selection. Style runs adjust on
insert/delete to preserve formatting across edits.
Fig roundtrip: import characterStyleIDs + styleOverrideTable from
TextData, export back with deduped style table.
B/I/U/S toggle buttons in TypographySection.
TextEditor class in core — cursor positioning, selection, word
boundaries, line navigation via CanvasKit Paragraph API
(getGlyphPositionAtCoordinate, getRectsForRange).
Renderer draws selection highlights and blinking caret directly
on the canvas. Blue outline around text node during editing.
Phantom textarea captures input, IME composition, clipboard,
arrow keys, Home/End, word/line movement (⌥/⌘ modifiers).
Replaces the old visible <textarea> overlay.
Rust: list_system_fonts and load_system_font Tauri commands using
font-kit crate for cross-platform system font access.
TS: font shim detects Tauri runtime and uses invoke() for font
listing/loading instead of queryLocalFonts (unavailable in WKWebView).
Commands:
- open-pencil info <file> — document stats, node types, fonts
- open-pencil tree <file> — visual node tree with agentfmt
- open-pencil find <file> — search by name/type with rich output
- open-pencil export <file> — render to PNG/JPG/WEBP at any scale
Uses canvaskit-wasm/full for headless CPU rasterization.
All commands support --json for machine-readable output.
agentfmt provides consistent colored terminal formatting.
Move engine (scene-graph, renderer, layout, codec, kiwi) into
packages/core/ as a Bun workspace package. The app's src/engine/
files become thin re-export shims so all existing imports still work.
- Bun workspace with packages/core
- Zero DOM dependencies in core
- Headless-friendly CanvasKit init (locateFile option)
- Constants split: engine constants in core, UI constants in app
- All 76 unit tests pass, lint + typecheck clean, vite build works
