Vance IngallsandClaude Opus 4.6 59e1d0787f fix(studio): prevent composition switch loop on sub-composition navigation (#754) 
Circular state update between activeCompPath and compositionStack caused
the preview to flicker when navigating to sub-compositions and scrubbing.
The cycle: activeCompPath change → useEffect updates compositionStack →
onCompositionChange fires → setActiveCompPath + refreshPreviewDocumentVersion
→ re-render → effect re-evaluates → repeat. Fixed by guarding both sides:
onCompositionChange skips if path unchanged, updateCompositionStack skips
notification if top-of-stack ID unchanged.

README.md

@hyperframes/studio

Browser-based composition editor UI for Hyperframes. Provides a visual timeline, code editor, and live preview for building video compositions.

Install

npm install @hyperframes/studio

What it does

The studio is a React application with:

  • Visual timeline — drag, resize, and arrange elements on tracks
  • Code editor — edit HTML and GSAP scripts with CodeMirror (syntax highlighting, autocomplete)
  • Live preview — see changes in real time as you edit
  • Composition inspector — view and modify element properties

Development

The studio is embedded in the hyperframes preview command. To develop the studio UI itself:

cd packages/studio
bun run dev        # Start Vite dev server
bun run build      # Build for production
bun run typecheck  # Type-check

Tech stack

  • React 18/19, Zustand (state management)
  • CodeMirror 6 (editor)
  • Tailwind CSS (styling)
  • Vite (bundler)
  • Phosphor Icons
