Vance IngallsandClaude Opus 4.6 45996c3523 fix(studio): serve runtime locally instead of from CDN
The Vite dev server was loading the HyperFrames runtime IIFE from
cdn.jsdelivr.net. This caused compositions using window.__hyperframes
(e.g., fitTextFontSize) to fail when the CDN script didn't load in
the iframe context.

Add a /api/runtime.js endpoint to the Vite plugin that serves the
local built runtime, matching what studioServer.ts already does for
the CLI embedded server.

@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)
